CNC Milling

The workpiece is loaded into the special chuck in the center of the machine. The cutter that moves on the vertical and horizontal plane will move around the workpiece, and then cut it into shape.

CNC-turning-2

CNC Turning

CNC turning is used for bar or cylinder-shaped components machining. A metal or plastic workpiece is loaded onto a locking chuck. Then, a computer-guided cutter is used to remove material from the workpiece while the chuck rotates at a high speed. It produces the workpiece into the shape and size required.

Wire-EDM

Wire EDM Machining

Wire EDM machining works by creating an electrical discharge between the wire or the electrode and the work piece. As the spark jumps across the gap, material is then removed from the work piece and the electrode.

CNC Grinding

CNC grinding machines are to use a rotating grinding wheel to achieve material removal on a metallic workpiece by means of cutting. Grinding machines are mostly used for the hard-fine machining of workpieces.

What Our Clients Are Saying About Us

When we were looking to have parts manufactured, we had tight deadlines with an even tighter budget. Promise Technology understood our constraints and worked with us closely to get our parts to high quality level. I can not recommend Promise Technology enough. They are professional, communicative and efficient. I felt very happy to work with them.
Jon Bakken
Mechanical design engineer - Apex
We initially started working with Promise Technology, as we needed a high quality product developed within a very short lead time. The entire process went very smoothly and we received the products ahead of schedule. We were pleased with the final results and we found working with them very easy, as they offered very good technical advice.
