Milling

Milling is the process of machining using rotary cutters to remove material by advancing a cutter into a workpiece. It's one of the most commonly used processes for machining custom parts to precise tolerances.
We have seven mills.
Turning (Lathe)

Turning is a machining process in which a cutting tool describes a helix toolpath by moving linearly while the workpiece rotates. This is often how cylindrical objects are created. A lathe is used to rotate the workpiece.
We have five lathes.
Wire EDM

EDM is known as spark machining, where a desired shape is obtained by using electrical discharges to remove material from a workpiece. This method allows us to shape materials that are extremely difficult to machine conventionally.
We have two Wire EDMs.
Surface Grinding

Surface grinding is a process that uses a rotating abrasive wheel to smooth the flat surface of metallic or non metallic materials and achieve various finishes.
This time intensive process produces the incredible tolerances required by precision industries.

Design to Production

Left and Right Guides

Aluminum plates requiring a slight asymmetry achieved through consultation from our DFM team to meet cost requirements.
Aerospace Bearings

Hardened metal exterior with mirror finish on inside surfaces.
Bracket for Manufacturing

Each of these holes called for radial tolerance of 0.005” and an extremely short cycle time in production.
Large Tool Brace

Precision aluminum trays are almost 9” across and required precise communication between our mills and lathes.
Small Tool Brace

Similar to the aluminum tool brace, this brass brace was offered as an alternative for application in maritime use cases.
Optical Sighting Equipment

Stainless steel trays required CAD, CAM, and trigonometry expertise to meet precision requirements.

What Our Clients Say

Tony Costa, Production Manager, MBT Systems Ltd.

I want to take a moment and thank you for the effort from you and your team on creating the machined parts that are used in our new cutting tools. As prototype parts, these were brand new pieces that we have not made previously. The personal service provided and the willingness to work with us on an ongoing basis has allowed us to be highly responsive to our customers. Pro Machine is our preferred source for machine services when we are taking prototype pieces into volume.
Duane Morgan, Mechanical Engineer, Soma Manufacturing

I have been doing business with Pro Machine & Engineering since the early 90’s. Pro always gives you their best whether it’s a tight specification or working through technical issues. Pro Machine is always my first choice when machining is required.
Dave Pfister, Principle Mechanical Engineer, Sanmina - Newisys

From prototypes, DFM reviews through production ramp Pro Machine is my go to shop for machining services. They have a wide range of capabilities, experienced machinists and modern CAD/CAM/ CNC equipment for a shop of their size.
