What is the difference between CNC milling and CNC turning?

CNC Milling uses rotating tools to remove material from a stationary workpiece, ideal for complex 3D shapes, slots, and holes. CNC Turning rotates the workpiece against a stationary tool, perfect for creating cylindrical parts like shafts and pins. Many parts require both processes, which we can handle as a complete machining service.

What is your typical tolerance for machined parts?

Our standard machining tolerance is ±0.005mm (±0.0002"). Tighter tolerances are achievable based on part geometry and material. We will perform a DFM analysis and recommend the optimal process to meet your specifications.

Do you provide CNC prototyping services?

Yes, rapid prototyping is one of our core services. We can quickly produce functional prototypes from your CAD files in a wide range of materials, allowing for design validation before moving into production.

What materials can you machine?

We machine a vast range of materials, including Aluminum (6061, 7075), Stainless Steel (303, 304, 316), Brass, Copper, Titanium, and various Engineering Plastics (PEEK, Delrin, Nylon).

What information do I need to get a CNC machining quote?

For the fastest and most accurate quote, please provide: 1) 3D CAD file (STEP or IGES preferred), 2) 2D drawing (PDF or DWG) with critical dimensions/tolerances, 3) Material specification, 4) Quantity, and 5) Any special finishing requirements.
