What is CNC machining?CNC (Computer Numerical Control) machining is a manufacturing process where pre-programmed computer software controls the movement of machinery and tools. It's used for a wide range of materials, including metal, plastic, and wood.2. What materials can be used in CNC machining?CNC machines can handle a variety of materials such as:Metals (aluminum, steel, titanium, brass, copper)Plastics (ABS, POM, nylon, acrylic)Wood and composite materialsCeramics and more.3. 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.4. How do I choose the right CNC machining service?Factors to consider include:Material requirementsTolerance and precisionProduction volumeLead timeCost-effectiveness5. What is the typical lead time for CNC machining?Lead times depend on the complexity of the part, the material, the required finish, and the production volume. Typically, CNC machining can take anywhere from a few days to a couple of weeks for a prototype or small batch, but larger orders may take longer. Normally 7 days for prototyping and 20 days for mass production shipment.6. What is the maximum size of a part that can be CNC machined?The size limitations depend on the specific CNC machine being used.
