The process of repairing a crankshaft used to be very complicated and stressful. To repair a damaged crankshaft, one had to dismantle the engine, pack the parts like fragile glassware, and ship them off to a workshop. It was expensive, slow, and honestly… a huge headache. However, the onsite crankshaft grinding machine arrived and flipped the script.
Features of the Crankshaft Grinding Machine
1. Portable Design:

The Crankshaft Grinding Machine isn’t just portable—it’s precise.
We’re talking accuracy within 10 microns (that’s micrometer-level precision), with surface finishing that complies with international quality standards. It’s lightweight, simple to carry, and super user-friendly.
Technicians don’t need to be hardcore specialists. With a quick 1-week training (yes, literally just a week), they’re able to grind and polish crankshafts like pros.
