#grid-OD0YWTnu7RSFLeX{padding-right:15px;padding-left:15px;} Before we discuss what materials cannot be CNC machined, we first need to understand the principles and limitations of CNC machining, and then see what materials are not suitable for CNC machining. CNC machining has become one of the core technologies of modern manufacturing due to its high precision, high efficiency and wide applicability. However, not all materials are suitable for machining by conventional CNC processes. The physical or chemical properties of some materials can cause excessive tool wear, poor machining quality, and even damage to machine tools. This article will explore which materials are difficult or impossible to use CNC machining, and analyze the reasons behind it and possible alternatives.CNC machining is usually achieved by cutting materials with tools, which mainly depends on two factors. One is the hardness of the tool. The tool must be harder than the material being machined, otherwise it will wear out quickly. The second is material stability: the material must have a certain strength to avoid deformation or fragmentation due to cutting force. If the material cannot meet the above conditions, conventional CNC machining will be difficult to carry out.1. Superhard materials:Typical materials: natural diamond, cubic boron nitride (CBN)Processing difficulties: The hardness of diamond is as high as Mohs 10, and CBN is close to 9, which is much higher than conventional carbide tools (hardness is about 8-9). The tool will quickly become blunt or even break during cutting.Alternative solutions:Use electrical discharge machining (EDM) or laser cutting to remove materials using heat or discharge principles.2. Highly brittle materialsTypical materials: ordinary glass, unsintered ceramics, high-purity graphiteProcessing difficulties:The material is prone to breakage during cutting, and burrs or cracks are generated on the edges, making it difficult to ensure accuracy. For example, glass may shatter instantly under tool pressure.Alternative solutions:Use grinding technology (such as precision grinders) or water jet cutting to reduce direct impact.3. Highly viscous or soft materialsTypical materials: rubber, silicone, soft plastics (such as PE, PU)Processing difficulties:The material is highly elastic, and the tool is prone to "pulling" rather than cutting, resulting in deformation or rough surface. Soft plastics may also melt due to frictional heat and stick to the tool.Alternatives:Freeze curing: Processing after hardening the material at low temperature (such as cooling rubber with liquid nitrogen).Use high-speed spindles (above 20,000 RPM) to reduce heat accumulation.4. High-temperature sensitive materialsTypical materials: lead, tin, PVC plasticsDifficulties in processing:Low-melting-point metals (such as tin melting point 232°C) are easy to soften and stick to the tool during high-speed cutting; PVC releases toxic chlorine gas at high temperatures, which endangers operators.Alternatives:Control cutting temperature (such as using coolant), or use 3D printing or injection molding instead.5. Heterogeneous composite materialsTypical materials: Carbon fiber reinforced composite materials (CFRP), glass fiberDifficulties in processing:Material anisotropy leads to uneven cutting force and extremely fast tool wear; carbon fiber may also delaminate, affecting structural strength.Alternatives:Use diamond-coated tools and optimize cutting parameters (low feed, high speed).It is worth noting that although many materials are difficult to process with conventional CNC, they are not absolutely "unprocessable". The following methods can be used to break through the limitations:Special tools: such as polycrystalline diamond (PCD) tools for processing carbon fiber.Process improvement: combined with cooling technology (such as cryogenic processing), vibration suppression, etc.Hybrid process: CNC rough processing first, then EDM or laser finishing.For example, although nickel-based high-temperature alloys (such as Inconel) have extremely short tool life due to high strength and high thermal conductivity, they can still be processed with special ceramic tools and extremely low feed speeds, but the cost is extremely high. ConclusionAlthough CNC processing is powerful, its limitations also remind us that material properties and processing technology need to be highly matched. When facing special materials, engineers need to comprehensively consider cost, efficiency and quality, and flexibly choose traditional cutting, special processing or additive manufacturing solutions. In the future, with the development of technologies such as superhard tools and intelligent cooling systems, the boundaries of CNC may be further broadened, but "applying technology according to materials" will always be the core logic of the manufacturing industry.

#cell-WH8P2NHdml7WRKD{order:0;} EDM machine tools: the "invisible engraver" of precision machining     In modern manufacturing, the ability of precision machining technology to form complex parts directly affects the performance and quality of products. As a non-contact special machining technology, electrical discharge machining (EDM) has become an "invisible engraver" for high-hardness materials and complex geometric parts by virtue of its unique machining principle. This article will analyze the technical principles, core advantages and applicable scenarios of EDM, and compare it with traditional CNC machining to help you understand its key role in industry. #cell-pJYOAFpmrH2oJdf{order:0;} Processing principles and core features of EDM machine tools #cell-t2GNmAJ7rhnq22y{order:0;}     The EDM machine tool generates instantaneous high temperature (up to 8000-12000℃) through high-frequency pulse discharge between the electrode and the workpiece, causing the metal material on the surface of the workpiece to partially melt and vaporize, and gradually eroding the material. The entire process does not require physical contact, so it is not limited by the hardness of the material and can achieve micron-level precision. EDM machine tools can process high-hardness conductive materials such as hardened steel, cemented carbide, and titanium alloy. And through electrode shape replication or wire cutting path control, complex structures such as deep grooves, micropores, and special-shaped cavities can be processed, and fine structures that CNC processing cannot perform can be processed. The EMD processing process has no mechanical cutting force, avoids deformation of the workpiece, and is especially suitable for thin-walled and fine parts. At the same time, EDM processing can achieve mirror effects or specific roughness requirements by adjusting the discharge parameters. #cell-CBWeToeMgoRQ3me{order:0;} Typical application scenarios of EDM #cell-v89QHBl1Fa6lPKs{order:0;} 1. Mold manufacturing fieldInjection molds and die-casting molds: Processing complex cavities such as deep cavities, narrow slits, and sharp corners to solve the interference problem of traditional CNC tools.Precision stamping molds: Directly process cutting edges and gaps with micron-level precision on hardened mold steel.2. Aerospace and medical equipmentEngine blade film cooling holes, fuel nozzle micropores (aperture can be as small as 0.1mm).Titanium alloy precision parts of surgical instruments (such as porous structures of orthopedic implants).3.

When dealing with high-hardness materials, complex microstructures, and zero-deformation processing requirements, EDM shows irreplaceable advantages. Engineers need to flexibly choose between the two technologies based on material properties, part geometry complexity, and cost budget to achieve the best balance between efficiency and precision.

#cell-hte1benjf5oDI8m{order:0;} In the world of CNC machining, the choice of metal materials directly affects machining efficiency, part accuracy and final cost. Although no metal can "take all" in all machining scenarios, some metals have become the "darlings" of CNC machining due to their excellent comprehensive performance. They are not only adaptable to a variety of machining processes, but also can show stable performance in the fields of auto parts, aerospace, etc. #cell-sf5ykdgp7btLkmx{order:0;} Aluminum alloy: the all-rounder in CNC machining #cell-n2EfqeyJkwAiHb7{order:0;} ▶ Aluminum alloy is one of the ideal materials for CNC machining, especially in the fields of auto parts and aerospace.In terms of processing performance, aluminum alloy has moderate hardness (the hardness of common 6061 aluminum alloy is about 95HB), low cutting resistance, slow tool wear, and can greatly improve processing efficiency. Its thermal conductivity is excellent, about 3 times that of steel, and the heat generated during processing can be quickly dissipated to avoid the accuracy of parts affected by thermal deformation. In addition, aluminum alloy has good plasticity, and smooth surface quality can be obtained whether it is milling, turning or drilling, without complicated subsequent processing.In terms of cost, the price of aluminum alloy raw materials is relatively affordable, and the material utilization rate is high during processing, which is suitable for mass production. For example, engine brackets in the auto parts field and lightweight structural parts in aerospace are mostly processed with aluminum alloys, which can meet strength requirements and achieve weight reduction goals. #unit-JiwtST2rBObN3b1 .ce-image_inner{justify-content:center;}#unit-JiwtST2rBObN3b1 .ce-image_item{--svg-color:rgba(2, 190, 240,1);}#unit-JiwtST2rBObN3b1 .ce-image{--image-effect:1;} #cell-yM6YUncJHFDbB4G{order:0;} Brass: The “stable” material for precision machining #cell-RI1CNylw30ktqH0{order:0;} ▶ Brass has become a popular choice for precision parts processing due to its excellent cutting performance.Brass has a low hardness (about 50-100HB) and a uniform internal structure. It is not easy to produce burrs and cracks during processing, and can easily achieve high-precision dimensional control (tolerance can be stabilized within ±0.01mm). It has good self-lubrication, is not easy to stick to the tool during cutting, and can reduce tool loss. It is especially suitable for processing parts with fine threads and complex holes, such as hydraulic valve components in auto parts and connectors in precision instruments.In addition, brass has good conductivity and corrosion resistance. After processing, it can meet the needs of some scenarios without additional plating, further reducing production costs. However, brass has a high density and is relatively limited in its application in weight-sensitive aerospace parts.Compared to brass, copper is widely used in new energy vehicle charging systems, with CNC-machined copper and copper alloy components being widely used. High-precision copper parts (such as charging gun terminals and battery connection pins) ensure stable current transmission. In the battery system, CNC-machined copper tabs and busbars efficiently collect power, while copper sleeves precisely adapt to the heat dissipation structure, balancing electrical and thermal conductivity. In the cooling system, precision-machined copper tubes, with their excellent dimensional accuracy, ensure reliable heat dissipation under high-voltage environments. Connectors and sensor contacts made from brass and other alloys, manufactured through CNC machining, maintain excellent conductivity while meeting complex assembly requirements through high-precision morphology, fully supporting the efficient operation of the vehicle's power transmission and thermal management systems. #unit-ZtQbrQCj6DD2heh .ce-image_inner{justify-content:center;}#unit-ZtQbrQCj6DD2heh .ce-image_item{--svg-color:rgba(2, 190, 240,1);}#unit-ZtQbrQCj6DD2heh .ce-image{--image-effect:1;} #cell-Ivc0eD6y8fWr5Kg{order:0;} Mild steel: a cost-effective choice #cell-KmoRi3w3UkWEc0L{order:0;} ▶ Low carbon steel (carbon content <0.25%) is a "frequent visitor" in the industrial field and also occupies an important position in CNC processing.Its strength and toughness are balanced, and the cutting force during processing is moderate, which is suitable for various conventional processing technologies. Low carbon steel is cheap and the raw material supply is sufficient, which is suitable for mass production of structural parts, such as chassis brackets in auto parts and gear blanks in mechanical transmission. After heat treatment, low carbon steel can also improve the surface hardness and meet the wear resistance requirements.However, it should be noted that low carbon steel is easy to rust, and usually needs to be electroplated or painted after processing; and its thermal conductivity is not as good as aluminum alloy, so it needs to be cooled during high-speed processing to avoid deformation of parts. #cell-rKUmHsusNx5cDKr{order:0;} Stainless steel (304/316): the “preferred material” in the field of corrosion resistance #cell-FMvPGMnafa6EgaQ{order:0;} ▶ In scenarios with high requirements for corrosion resistance, 304 and 316 stainless steel are the first choice for CNC machining.304 stainless steel contains chromium-nickel alloy, has strong oxidation resistance and stable processing performance, and is suitable for making parts for food machinery and medical equipment; 316 stainless steel has better resistance to salt spray and high temperature corrosion due to the addition of molybdenum, and is often used in aerospace pipeline systems and exhaust parts in auto parts.Although stainless steel has a high hardness (about 150-200HB) and the tool wears faster during cutting, high-precision parts can still be efficiently processed by selecting carbide tools and optimizing cutting parameters (such as reducing feed speed and strengthening cooling). #cell-MQmLx3oJ6Va6DQB{order:0;}#unit-46nOCFh3JPB5DUx .ce-image_inner{justify-content:center;}#unit-46nOCFh3JPB5DUx .ce-image_item{--svg-color:rgba(2, 190, 240,1);}#unit-46nOCFh3JPB5DUx .ce-image{--image-effect:1;} Key principles for choosing the right metal ▶ To determine whether a metal is suitable for CNC machining, the following factors need to be considered comprehensively:• Machining efficiency: Material hardness and cutting resistance directly affect machining speed and tool life;• Precision control: Thermal conductivity and plasticity determine whether the parts are easily deformed due to machining heat or stress;• Cost adaptation: Raw material prices, machining energy consumption, and subsequent processing costs must match the project budget;• Scenario requirements: The strength, corrosion resistance, weight and other properties of the parts must meet the special requirements of the application field (such as the requirements of aerospace for lightweight and high temperature resistance).Different metals have their own advantages, and the selection needs to be combined with the drawing requirements, performance indicators and cost budget of the specific project.

In the dynamic landscape of the manufacturing industry, characterized by the continuous emergence of new technologies, a pertinent question often surfaces: Is CNC (Computer Numerical Control) processing technology losing its edge and becoming obsolete? This concern, however, stems from a misapprehension of the current standing and future trajectory of CNC processing in modern manufacturing. Far from being obsolete, CNC processing continues to play an indispensable role across diverse sectors, including automotive and aerospace, owing to its unique set of advantages. Moreover, it is undergoing a process of continuous innovation and enhancement.​ ▶   1. The Core Advantages Of CNC Machining Are Irreplaceable #cell-2YIaRIHamFjvIme{padding-top:1vw;}#unit-5jmFxwFdLb2Hx1R{padding-bottom:1vw;} CNC machining has firmly established itself in the manufacturing sector, primarily due to its irreplaceable core strengths.​● 1.1 Unparalleled Machining Accuracy​CNC machining is renowned for its ability to achieve an extremely high level of precision. Tolerances can be meticulously controlled within a range of ±0.001mm or even finer. This precision is the bedrock for ensuring the performance and safety of products with exacting precision requirements. In the automotive industry, for instance, precision transmission parts demand such high - level accuracy. Similarly, in the aerospace domain, key structural components, like the turbine blades in aircraft engines, feature complex curved surfaces and require precise dimensional control. These blades can only be consistently and accurately produced through CNC machining. According to industry data, in the production of aircraft engine turbine blades, CNC machining has reduced dimensional errors by over 80% compared to traditional machining methods, significantly enhancing engine efficiency and reliability.​● 1.2 Exceptional Material Adaptability​CNC machining exhibits remarkable adaptability to a wide spectrum of metal materials. Whether it is common metals such as aluminum, steel, and copper, or more challenging materials like titanium alloys and high - temperature alloys, CNC machines can effectively process them. As a professional CNC machining foreign trade company, we have amassed extensive experience in handling various metal parts and components. We have successfully processed over 100 different types of metal materials, enabling us to adeptly address the processing challenges presented by diverse materials. For example, when working with titanium alloys, which are widely used in aerospace due to their high strength - to - weight ratio, our CNC machining processes ensure that the material's integrity is maintained while achieving the desired shape and finish.​● 1.3 Unrivaled Mass Production Stability​One of the standout advantages of CNC machining lies in its stability during mass production. Once the program is set, it can guarantee the consistency and stability of large - scale part production, effectively minimizing quality issues arising from human errors. In industries such as automotive parts manufacturing, which rely on the large - scale production of standardized components, this stability is crucial for enhancing production efficiency and ensuring product quality. A leading automotive parts manufacturer reported a 30% reduction in defect rates after switching to CNC machining for mass production, along with a 25% increase in overall production efficiency. #cell-9tuRyEw63WhnqR6{padding-top:1vw;padding-bottom:1vw;}#unit-qkuiEVnXb4RzABD .ce-image_inner{justify-content:center;}#unit-qkuiEVnXb4RzABD .ce-image_item{--svg-color:rgba(2, 190, 240,1);}#unit-qkuiEVnXb4RzABD .ce-image{--image-effect:1;} #cell-9zEzc7eGkOxVlJ2{padding-top:1vw;} ▶   2.

However, this does not imply that they can supplant CNC machining entirely.​● 2.1 Limitations of 3D Printing in Comparison​3D printing has its own set of advantages, particularly in complex structure prototyping and small - batch personalized product manufacturing. Nevertheless, it lags behind CNC machining in several crucial aspects. In terms of machining accuracy, surface quality, and the machining efficiency of high - strength metal materials, CNC machining holds a clear edge. For aerospace metal parts that must withstand high loads, CNC machining can effectively ensure their mechanical properties and structural stability. In contrast, 3D - printed products still need significant improvement in these areas. A study comparing 3D - printed and CNC - machined aerospace components found that CNC - machined parts had a 50% higher fatigue life and a surface roughness that was 70% lower, making them more suitable for high - stress applications.​● 2.2 Cost - effectiveness in Production​When it comes to large - scale production of metal parts, CNC machining enjoys a distinct cost advantage. The equipment and material costs associated with 3D printing are relatively high, making it difficult to compete with CNC machining in large - scale manufacturing scenarios. Therefore, rather than being substitutes, CNC machining and emerging technologies are more complementary, each catering to different manufacturing needs. For example, in the production of 10,000 metal brackets for an automotive assembly line, the cost per unit using CNC machining is 30% lower than that of 3D printing, considering both equipment depreciation and material consumption. #cell-BqqNTLwd1YGYmld{padding-top:1vw;padding-bottom:1vw;}#unit-i5DWJ3lCEqgI0F3 .ce-image_inner{justify-content:center;}#unit-i5DWJ3lCEqgI0F3 .ce-image_item{--svg-color:rgba(2, 190, 240,1);}#unit-i5DWJ3lCEqgI0F3 .ce-image{--image-effect:1;} ▶   3.
