Overview: What is CNC Machining?
CNC (Computer Numerical Control) machining is an automated manufacturing process that uses high-speed cutting tools to precisely shape metal or plastic stock materials. Common CNC machines include milling machines, lathes, and routers with 3-axis to 5-axis capabilities. The cutting approach varies - the workpiece may be stationary while the tool moves, the tool may be stationary while the workpiece moves, or both may move simultaneously.
Skilled machinists program the tool paths based on CAD models of the final part geometry. CNC machining offers high precision and repeatability, making it suitable for custom parts across industries like aerospace, medical, robotics, and electronics. UTM provides CNC machining services quoting over 40 materials from aluminum to engineered plastics like PEEK and Teflon. The computer control enables automated, efficient material removal through processes like milling, drilling, and turning.

Quality Services
Clients Love
UTM is an extremely professional company with great customer service. Everything we ordered arrived as expected. There were some initial problems, but Kobe helped find a solution that worked for both sides. We will definitely use them again.
UrbanFor my last order, the customer support was amazing. Kobe helped me solve a logistics issue and the algo parts were excellent quality as expected. I'm super happy with the support and service. For my next order, I'll be increasing the number of parts since I know the quality and service will be great.
Andres CI ordered 50 CNC machined stainless steel parts and they turned out great. The dimensions were right on and the parts were clean and smooth. I'll definitely order from them again.
Wim Peter
They do what they say they'll do. Sometimes they even finish sooner than promised. If we have any problems or questions, they always give us helpful answers. You can count on them.
