Tolerances
Standard machining toleranc：±0.05 mm
Precision features：±0.01 mm (depending on part design)
Final tolerance depends on part geometry, material condition, machining requirements, and inspection requirements.
Prototype Machining Materials & Surface Finishing
Machmaster supports prototype manufacturing using a wide range of materials — from aluminum and stainless steel to brass and engineering plastics.
Aluminum
Aluminum is widely used in CNC machining for its excellent machinability, lightweight properties, and corrosion resistance. It’s ideal for prototypes, enclosures, structural parts, and applications where weight and strength must be balanced.
| Available Aluminum at Machmaster: | Aluminum 6061, 2024, 5052, , 6063, 6082, 7075-T6. |
Stainless Steel
Stainless steel offers outstanding strength, wear resistance, and corrosion protection. It’s a preferred choice for high-stress or outdoor parts across industries like medical devices, automotive, and consumer electronics.
| Available Stainless Steel at Machmaster: | Stainless Steel ,304,316,316L,430, ,440C, 17-4PH. |
Brass
Brass is known for its good machinability, aesthetic appeal, and electrical conductivity. It’s commonly used in CNC parts for plumbing components, fittings, decorative hardware, and electrical connectors.
| Available Brass at Machmaster: | Brass C27400, C28000, C36000 |
Copper
Copper provides excellent thermal and electrical conductivity. CNC machined copper parts are widely used in electronics, heat sinks, and industrial components requiring rapid heat transfer or low resistance.
| Available Copper at Machmaster: | Copper C101(T2), C103(T1), C103(TU2), C110(TU0), Beryllium Copper |
Titanium
Titanium combines high strength, low weight, and excellent corrosion resistance. Though harder to machine, it’s ideal for aerospace, medical implants, and demanding applications where material performance matters.
| Available Titanium at Machmaster:: | Titanium Alloy TA1, Alloy TA2, Alloy TC4/Ti-6Al 4V |
Plastics
Engineering plastics like ABS, POM, and PC are lightweight, cost-effective, and easy to machine. They’re suitable for functional prototypes, insulation components, housings, and parts requiring impact resistance or electrical isolation.
If you have special material requirements, please leave a message with the specific specifications, and our engineers will evaluate them for you.
Machmaster provides finishing options to create prototypes close to final production appearance.
As Machined
The part is left as-is from CNC machining, offering a cost-effective solution with visible tool marks and a standard roughness of 3.2 μm (126 μin), plus deburring for safe handling.
Anodizing enhances corrosion and wear resistance by forming a protective oxide layer on aluminum or titanium surfaces. It also allows for decorative coloring and improves overall part durability.
Bead Blasting
Bead blasting produces a uniform matte finish by removing surface imperfections. Commonly used to improve appearance before anodizing, plating, or coating.
This dry finishing process applies powder to metal parts, then cures it into a tough, uniform coating. It offers excellent durability and is available in many colors and textures.
Electroplating uses electric current to deposit a metal layer onto a part, enhancing hardness, conductivity, and appearance with finishes like chrome or nickel.
Polishing removes surface flaws and creates a reflective, smooth finish. It’s used to improve aesthetics, reduce friction, and prepare parts for secondary coatings.
Brushing applies a fine, directional texture using abrasive belts or pads. Often used for decorative metal finishes or to visually mask minor surface defects.
Applied primarily to aluminum, Alodine coating creates a corrosion-resistant and paint-ready surface, significantly improving both protection and finish durability.
