The unique shape of Palmgren’s electric hand grinders provide exceptional control with less operator fatigue.
Each of the three available models has an efficient motor design that conserves power and runs cooler.
Highly accurate, the electric hand grinders are ideal for rotary filing, deburring, cleaning and polishing applications.
Related Glossary Terms
- fatigue
fatigue
Phenomenon leading to fracture under repeated or fluctuating stresses having a maximum value less than the tensile strength of the material. Fatigue fractures are progressive, beginning as minute cracks that grow under the action of the fluctuating stress.
- filing
filing
Operation in which a tool with numerous small teeth is applied manually to round off sharp corners and shoulders and remove burrs and nicks. Although often a manual operation, filing on a power filer or contour band machine with a special filing attachment can be an intermediate step in machining low-volume or one-of-a-kind parts.
- polishing
polishing
Abrasive process that improves surface finish and blends contours. Abrasive particles attached to a flexible backing abrade the workpiece.
