CNC Machining

CNC Machining

CNC (Computerized Numerical Control) Machining is a subtractive manufacturing process which cuts away the unwanted material from a block of material to form the structure of the part. Compared to the SLA/SLS and other additive manufacturing processes, CNC Machining has the advantages of tighter tolerance, bigger building size, smoother part surface, much cheaper material cost and capacity of target material. As one conventional manufacturing process, CNC machining is widely used for the manufacture of prototype, precision component, big and bulky part, low and high volume production.

At Honkia, our CNC machining tolerance is ± 0.1/100 mm. For the specific tighter tolerance demand noted, we could pay special attention to achieve it. For the uncharted tolerance demand, we use tolerance standard DIN ISO 2768-f for the machined plastic and metal parts. The materials we have CNCed include: ABS, PC, ABS+PC, Acrylic, PP, PS, POM, PA, PA+GF, TEFLON, Carbon Fiber, Bakelite, Wood, Aluminum, Magnesium, Titanium, Iron, Brass, Copper, Stainless steel, etc.

CNC Aluminum Prototyping

One of the fast growing and wide applications of CNC machining today is rapid prototyping for its advantages of tight tolerance, large building size, target and cheap material, accurate threading, and usually cheaper prototyping cost compared to the additive manufacturing processes, thus CNC machined prototypes or parts provide more reliable and economical feedback on mechanism and strength verification. For the part with big size and simple geometry, its manufacturing time and cost by CNC machining are possibly shorter and much lower than the additive manufacturing processes.

CNC Machined Prototype

Though more and more Additive Manufacturing processes are developed and widely used for rapid prototyping & manufacturing in western countries, CNC machining is still the leading rapid custom manufacturing process in China for its real and cheap materials, inexpensive and mature CNC machines and great labor cost advantage. No matter big or small size, simple or complex geometry, visual or mechanical verification, low or high volume production, CNC machining is always the competitive choice for product prototyping to production.
