Protomatic Takes a Microscopic Look at Parts

Protomatic recently added a Keyence “Super Resolution Digital Microscope” to its arsenal of inspection equipment. “Here at Protomatic, we are always curious about what the parts we make look like at the microscopic level,” said Vice President, Doug Wetzel. “Sure, it’s overkill at times and may be too much information, but by understanding the microfinish we put on a part and the impact it has on the part function, we are able to improve our customers’ final product.”

This microscope has a depth of field that is twenty times greater than optical scopes and is capable of performing topology measurements. Being digital, it is able to capture images for customers and employees for educational use.

With optical scopes, the lack of a large depth-of-field resolution is a handicap. The operator has to move the focal field manually and remember what they were viewing over the entire length of the part. With this digital scope and custom software, the image is clear in a single image. This clarity gives the machinist the insight they need to meet print finishes, and gives them insight to tool choice and condition.

Greater resolution and clarity can be achieved using shorter wavelength light, such as narrow wavelength blue lighting. By employing a blue filter and pixel shift technology, super resolution imaging that exceeds the limitations of an optical system is possible. The microscope is capable of capturing super resolution images that are impossible to obtain with white light.

Greater depth of field, topography and super resolution imaging give Protomatic and its customers a look at parts and products beyond anything ever seen before. Procurements like the Keyence microscope, which provide greater images during inspection, are why Protomatic is known for its life-saving precision.

Protomatic resides in a 30,000 square foot facility that can be found at 2125 Bishop Circle West in Dexter, Mich. The company’s specialties include prototype machining and custom short-run precision CNC milling and turning. In addition to those services, Protomatic will customize, produce and assemble parts and systems for numerous industries and jobs. Industries served include aerospace, automotive, medical, military and several other markets.
