Product Q&A

Q:1.What materials can be used in CNC machining?

CNC machines can handle a variety of materials such as: a.Metals (aluminum, steel, titanium, brass, copper) b.Plastics (ABS, POM, nylon, acrylic) c.Wood and composite materials d.Ceramics and more.

Q:2.What is the difference between CNC milling and CNC turning?

CNC Milling: Involves rotating the cutting tool and moving it along multiple axes to remove material from a workpiece. CNC Turning: Involves rotating the workpiece and using a stationary cutting tool to remove material, mainly for cylindrical parts.

Q:3.How do I choose the right CNC machining service?

Factors to consider include: a.Material requirements b.Tolerance and precision c.Production volume d.Lead time e.Cost-effectiveness

Q:4.What is the maximum size of a part that can be CNC machined?

The size limitations depend on the specific CNC machine being used. Large-scale machines can accommodate parts up to several meters in length, while smaller machines are typically limited to parts around 1000mm in length or less.

Q:5.What is the accuracy and tolerance of CNC machining?

CNC machining offers high precision, with tolerances typically ranging from +/-0.01mm to +/-0.1mm. However, the exact tolerance will depend on the machine and the material used.
