3 to 5 axis milling

3-axis CNC milling machines have a lower hourly rate than multi-axis milling machines. Their use is advantageous when machining on a limited number of faces.

4 to 5 axis CNC machining centers can produce parts with complex geometries and high precision. Minimizing the number of set-up, multi-axis machining allows high productivity while limiting human intervention.

2 to 8 axis turning

CNC turning is a subtractive manufacturing process. The machine is computer controlled (CNC) using specialized programming software. The part is held in a rotating chuck as a cutting tool removes material to shape it.

8-axis CNC turning allows complete machining of a part on all sides, including milling operations. This machine has two chucks. This process allows for increased productivity, precision and produces a finished part that is extracted from the machine using a robotic arm at the end of its cycle.

Wire and drill electrical discharge machining

The wire cutting process (EDM) allows high repeatability and extreme precision. This process allows us to cut very hard materials such as carbide and hardened tool steel. Wire cut materials (EDM) must have good electrical conductivity such as steels, aluminum, bronze, etc.

Surface and cylindrical grinding

Cylindrical grinding (external and internal) and flat grinding are procedures using abrasive wheels that allow an accuracy of 2 microns (.0001”) to be obtained and a surface finish up to 4 RA. This equipment also gives the possibility of working materials of great hardness such as carbide or hardened tool steel.

Assembly

We offer to our customers a simple and complex assembly service in order to provide them with a turnkey product. Using the combination of human expertise and technological tools, we assemble and adjust the machined components in accordance with the specifications.

Heat treatment

Oil and air quenching is done in-house to provide our customers with a better delivery time. Our processes and work instructions guarantee you an excellent control of quality. We also have several partners with who we collaborate for other specific heat treatments according to the customer’s request.

Surface treatment

We perform the black oxidation surface treatment in-house in order to offer a better delivery time. Our process is one of the best in the industry since it is done at 140°C. Our processes and work instructions guarantee you an excellent control of quality. This surface treatment blackens the metals. It protects them against oxidation and does not create extra thickness, unlike paint. We also have several partners with who we collaborate for other specific treatments according to the client’s request.
