CNC milling
CNC milling is suitable for planes, cavities, steps, hole systems and complex three-dimensional contour processing, and can be used for structural parts, shell parts, brackets, fixtures and functional verification parts. Suitable for metal and engineering plastic parts with clear requirements on dimensional accuracy, assembly relationship and surface consistency.
CNC turning is suitable for processing shafts, sleeves, cylindrical parts, threaded parts and rotary parts, and has stable performance in terms of dimensional repeatability, coaxiality and batch consistency. Suitable for precision parts projects that require fast delivery, stable repurchase and multi-batch consistency.
Five-axis CNC machining can reduce errors caused by multiple clampings and is suitable for complex curved surfaces, multi-faceted features, deep cavity structures and high-precision contour processing. For aerospace, medical equipment, robotics and high-end equipment parts, a better balance between accuracy, surface quality and manufacturing efficiency can be achieved.
Turning and milling combined processing can complete multiple processes such as turning, milling, drilling and tapping in one clamping. It is suitable for shaft parts with side holes, slots, flat surfaces or special-shaped features. It can reduce process transfer errors and improve the processing efficiency and dimensional stability of complex rotating parts.
CNC grinding is used for the finishing of high-precision mating surfaces, shaft surfaces, positioning surfaces and precision assembly parts, which can improve dimensional accuracy, flatness, roundness and surface roughness. Suitable for heat-treated steel parts, mold parts and functional parts sensitive to assembly gaps.
Commonly used materials: hardened steel, alloy steel, stainless steel
Tolerance capability: ±0.002 ~ ±0.01 mm
Wire EDM
Wire-cut EDM is suitable for processing high-hardness metals, complex internal and external contours, narrow grooves, sharp angles and mold structures. Due to the low cutting force during the machining process, the risk of deformation of thin-walled, fine-structured and hard materials can be reduced. It is often used for precision features that are difficult to access with traditional tools.
Commonly used materials: mold steel, carbide, stainless steel, alloy steel
Tolerance capability: ±0.005 ~ ±0.02 mm
Precision machining of centering machine
The precision machining of the centering machine is suitable for the production of slender shafts, small diameter parts, connectors, pins and high-consistency small metal parts. Through continuous feeding and stable support, the processing deformation of slender parts can be reduced, which is suitable for projects with high requirements on dimensional stability, batch repeatability and delivery efficiency.
Drilling and tapping are used for mounting holes, positioning holes, threaded holes and connection structures, and can be completed in conjunction with CNC milling, turning or a combination of turning and milling operations. By controlling hole position, hole diameter, thread depth and verticality, it helps parts meet the needs of assembly, fixation and repeated disassembly and assembly.
Commonly used materials: metal materials, engineering plastics
Tolerance capability: ±0.02 ~ ±0.05 mm

Aluminum alloy 6061
6061 is one of the most commonly used aluminum alloys for CNC machining. It has a balanced overall strength, corrosion resistance and processability, and is suitable for structural parts, shell parts, brackets, fixtures and functional verification parts. It supports anodizing (natural/black/color), sandblasting, brushing and other surface treatments, taking both appearance and delivery into consideration, making it the “universal first choice”.
7075 is a high-strength aviation-grade aluminum alloy with higher strength and better rigidity. It is suitable for load-bearing structural parts, sports equipment parts, aerospace-related parts and parts requiring high strength/lightweight. Suitable for projects with higher strength requirements; if you pay more attention to cost and versatility, you can give priority to 6061.
5052 is known for its good corrosion resistance and formability, and is often used in sheet metal and thin-walled parts; when used in CNC, it is also suitable for shell parts and structural parts that require corrosion resistance and surface consistency. If your parts are thin-walled/appearance parts and require a more stable surface treatment effect, 5052 is a very practical choice.
304 is one of the most common stainless steel materials. It is corrosion-resistant, reliable in strength, and suitable for long-term use of structural parts, appearance parts, connectors and equipment parts. It can be treated with sandblasting, brushing, polishing and other appearance treatments; if higher corrosion resistance requirements are required (seaside/chemical media), it can be upgraded to 316.
Compared with 304, 316 has stronger corrosion resistance and is suitable for humid seaside environments, chemical media, medical/food equipment related applications and high-demand terminal parts. For projects more sensitive to cosmetics and long-term reliability, priority is given to the 316 (generally more expensive than the 304).
303 is characterized by “easier cutting and processing” and is suitable for parts that require a large amount of turning/milling and pursue processing efficiency and surface cutting quality (such as shafts, threads, and connectors). If your parts are complex to process and are sensitive to efficiency, 303 is suitable; if corrosion resistance and versatility are more important, 304 is more commonly used.
45# is a commonly used medium carbon steel with a relatively balanced strength and toughness. It is suitable for general mechanical parts such as shafts, supports, load-bearing structures, fixtures and fixtures. It can be combined with heat treatment (tempering/quenching, etc.) to improve strength and wear resistance; if there is a need for rust prevention, it is recommended to blacken the surface, electroplating or spraying.
40Cr is a typical alloy structural steel with better strength, toughness and hardenability. It is suitable for high-strength shafts, gears, connectors and load-bearing parts. Often combined with quenching and tempering/surface quenching to obtain higher strength and wear resistance; suitable for working conditions that are more sensitive to fatigue and wear resistance.
H62 brass has good processability, excellent electrical and thermal conductivity, and good appearance and texture. It is suitable for connectors, terminals, valve bodies, decorative appearance parts and precision small parts. It can be polished, electroplated, etc. to achieve higher appearance requirements; if higher strength/wear resistance is required, higher strength brass or bronze systems can be considered.
Copper-T2 has excellent electrical conductivity, thermal conductivity and ductility, and is suitable for CNC machining of conductive connectors, heat dissipation parts, electrical terminals, shielding parts and experimental equipment components. If the project pays more attention to high strength, wear resistance or low cost, you can compare and choose among brass, stainless steel, aluminum alloy or alloy steel.
ABS has good comprehensive strength and toughness and is easy to process. It is suitable for structural verification parts, shell parts, prototypes and assembly parts. Can be used for post-processing such as painting, electroplating, etc. It is a commonly used engineering plastic with "cost-friendly + high verification efficiency".
POM (polyoxymethylene) has low friction, wear resistance and dimensional stability, and is suitable for precision motion/fitting parts such as gears, sliders, bushings, and guides. When more temperature or creep resistance is required, high-performance plastics such as PPS/PEEK can be upgraded.
PC has higher impact resistance and toughness, and is suitable for snap-on structures, transparent/translucent covers, stress-bearing shells and protective parts. If you need more toughness or more reliable assembly verification, PC is often a better fit than ABS.
PMMA (acrylic) has high light transmittance and good appearance and texture, and is suitable for parts that are sensitive to "transparency and appearance" such as transparent windows, lampshades, and display structural parts. If you care more about impact resistance and toughness, you can consider PC instead.
PEEK has the characteristics of high temperature resistance, chemical corrosion resistance and high strength, and is suitable for structural parts and insulation parts with extremely high performance requirements in high-end equipment, medical, aviation, etc. Suitable for "performance first" projects; if the budget is more sensitive, you can first evaluate PPS/PA and other solutions.
PPS has good temperature resistance, chemical resistance and dimensional stability, and is suitable for electrical insulation parts, temperature-resistant structural parts and parts with high environmental stability requirements. It is more cost-friendly than PEEK and is the "cost-effective route" for high-performance plastics.
PTFE (Teflon) has extremely low friction coefficient and excellent chemical corrosion resistance, and is suitable for seals, corrosion-resistant bushings, sliding parts, etc. The material is soft and easily deformed, and processing and assembly tolerances need to be evaluated more carefully.
PA6 has good toughness and wear resistance, and is suitable for structural parts, assemblies, wear-resistant/sliding parts and functional parts with daily strength requirements. If you need higher strength and more stable dimensional performance, you can choose PA66 or reinforced material route.
Compared with PA6, PA66 has higher strength, heat resistance and more stable dimensional performance, and is suitable for structural support parts, wear-resistant parts and assembly parts with higher strength requirements. When the temperature resistance/rigidity requirements are more extreme, PPS/PEEK can be further evaluated.
PP is lightweight and has good chemical resistance. It is suitable for corrosion-resistant container parts, structural parts and applications that require high material inertness. The material is soft and relatively low in rigidity. If higher strength and dimensional stability are required, POM/PA and other alternatives can be considered.
