In high-performance diesel and gas engines, the crankshaft’s surface finish is critical for smooth operation, oil film retention, and bearing life. Across Africa’s energy, marine, and industrial sectors, the use of a crankshaft polishing machine ensures that journals achieve the mirror-like finish required for optimal engine performance.
At Panesar Crankshaft Centre, we utilize advanced crankshaft polishing machines—both in situ and workshop-based—to support precise, efficient crankshaft restoration across Africa.
What Is a Crankshaft Polishing Machine?
A crankshaft polishing machine is a tool designed to refine the surface finish of crankpins and main journals after grinding or minor repair. Using specialized abrasive belts or pads, the machine removes micro-scratches, high spots, and minor imperfections—without altering the journal’s critical dimensions.
Why Use a Polishing Machine Instead of Manual Polishing?
- Consistent surface finish across all journals
- Controlled pressure and speed to avoid over-polishing
- Faster and more uniform than hand tools
- Compatible with all crankshaft materials and sizes
- Improves bearing life and reduces friction
A proper polish can mean the difference between a crankshaft that lasts years and one that fails prematurely.
Applications of Crankshaft Polishing Machines
- Final step after crankshaft grinding
- Surface correction for journals with light scoring or fretting
- Onboard engine maintenance in marine and FPSO vessels
- Diesel generators and stationary engines in power plants
- Mining and heavy equipment crankshafts
Whether you’re polishing crankshafts on a vessel in Mombasa, a refinery in Nigeria, or a power station in Ghana, we bring portable polishing machines to your engine.
