CNC Machining

Computer Numerical Control (CNC) machining of metal or plastic prototypes and tooling programmed directly from your CAD file

Variety of Applications

CNC machining is excellent for making jigs, fixtures, tools, molds, and prototypes.

Plastic or Metal Part Production

TriMech offers high-precision CNC machining with engineering-grade plastic materials (including ABS, polycarbonate, Nylon, and PEEK) and metal materials (including stainless steel, aluminum, and copper).

Low or High Volume Production

Extremely accurate process and is, therefore, ideal for low- and high-volume production of end-use production-grade metal and plastic components

Why choose CNC Machining?

CNC Machining Services, including milling, and turning for the production of high-quality parts using modern machining methods. With highly skilled machinists and industry-leading equipment TriMech can accommodate a vast array of manufacturing applications.

CNC machining is a subtractive fabrication method, whereby unwanted material gets milled (cut and removed) away from a block of metal or plastic.

CNC machining is usually a slower prototyping process than 3D printing parts. However, it is an extremely accurate process and is, therefore, ideal for low- and high-volume production of end-use production-grade metal and plastic components.

CNC Machining Service Overview

CNC Machine Programming

Fast and Precise Machining

TriMech is able to create CNC machined parts with at a fast rate.

At the same time, TriMech’s experienced engineers ensure the highest standards with cutting edge software and equipment.

Milling machine and workpiece

Variety of CNC Machines

TriMech’s facilities provide a variety of equipment such as single axis lathes for executing round parts such as nozzles, engine components and thread shafts.

Plus 4-axis machines, which substantially reduce turnaround time by eliminating intermediate setups and enabling undercuts and off-axis features.
