Available Material For CNC Machining
Our CNC machine shop can machine virtually any engineering material, including plastics, metals, alloys, foam or tooling board. Here is a list of our standard CNC machining materials available, other materials are upon request.
Aluminum is a highly ductile metal, making it easy to machine. The material has a good strength-to-weight ratio and is available in many types for a range of applications.
Brass has desirable properties for a number of applications. It is low friction, has excellent electrical conductivity, and has a golden (brass) appearance. It is commonly used in parts that need a large load.
Copper displays excellent thermal conductivity, electrical conductivity and plasticity. It is also highly ductile, corrosion resistant and can be easily welded.
Stainless steel features a high-temperature resistant, with good oxidation resistance and corrosion resistance. It is widely used in machine parts, contruction industry parts, etc.
Plastic is one of the most commonly used materials in the world because of its strong corrosion resistance, durable, waterproof, light weight, low cost and easy processing.
Titanium alloy is widely used in automobile industry because of its light weight, high strength and good corrosion resistance.
Special steel is a kind of steel with special composition, special production process, special structure and performance, which can meet special needs. Compared with ordinary steel, special steel has better strength and toughness, physical properties, chemical properties, biocompatibility and technological properties. It is widely used in machinery, automobile, military industry, chemical industry, home appliances, ships, transportation, railway and other fields.
Available Surface Finishes After CNC Machining Services
Surface finishes are applied after machining and can change the appearance, surface roughness, hardness and chemical resistance of the produced parts. Below are the mainstream surface finish types from DEK:
This is the standard choice, economical and rapid, the parts’ surface will leave visible machining marks. The surface finish is equivalent to 3.2RA μm (125 RA μin).
Polishing is to make the surface smooth by physical friction processing, it is often used to prevent corrosion and remove oxidation. After polishing, the parts have a smoother and brighter finish.
Bead blasting is the process of spraying abrasive on the surface of parts under high pressure, after sandblasting, the metal parts have a satin texture or frosted surface, eliminating the processing marks.
After anodizing, a hard non-conductive ceramic coating will be added on the surface of aluminum parts to improve the wear resistance and retain the metal texture and luster.
Electropolishing is the reverse process of electroplating, which simplifies the metal surface at the micro-level through chemical solution. After electropolishing, metal parts can be more bright and reduce surface roughness.
The black oxide is a chemical conversion coating, it is produced by a chemical reaction between iron and oxide salt in black oxide solution. The corrosion resistance of parts can be improved after black oxidation.
Powder coating can add a layer of solid and colorful polymer coating on the surface of parts, so as to improve the wear resistance and corrosion resistance.
Spray painting is to spray paint on the surface of parts in the air. After painting, the parts have various colors, improve the aesthetic appearance, and make the parts unique, enhance brand awareness.
Standard Tolerance Of Our Precision CNC Machining
The table below summarizes the standard tolerances of the parts produced by certified DEK. Tolerances up to .0008” (0.020mm) are available upon request.
