Frequently Asked Questions
▸ What is a crankshaft polishing machine used for?
The crankshaft polisher is used to provide final finishing to crankshaft journals and rods after grinding. It removes grinding marks and leaves a mirror surface, which is essential to reduce friction with bearings and extend engine life. The PV-2200 works with crankshafts up to Ø15.7x78.7 inches (Ø400x2000mm), using a felt disc of Ø19.7 inches (Ø500mm) at 780 rpm, controlling workpiece rotation between 14-34 rpm for uniform polishing.
▸ What is the maximum capacity of the PV-2200 polisher?
The Chinelatto PV-2200 handles crankshafts up to Ø15.7 inches (Ø400mm) diameter by 78.7 inches (2000mm) length. It has 4hp total motor, with 1hp for crankshaft rotation and 3hp for the polisher. Crankshaft rotation is controlled between 14-34 rpm, while the polishing disc spins at fixed 780 rpm. Comes with Ø6 inches (Ø152mm) crankshaft chuck plate, Ø19.7x0.8 inches (Ø500x20mm) felt disc and rotating tailstock included with the machine.
▸ What engine size fits in the PV-2200 crankshaft polisher?
The PV-2200 accepts crankshafts from small to large engines, as long as they don't exceed Ø15.7x78.7 inches (Ø400x2000mm). Works for car, pickup truck, some medium truck and stationary engine crankshafts. The limit is flywheel and counterweight diameter, not cylinder count. V6, V8 car engines fit easily. Heavy truck or marine engine crankshafts may exceed the machine's maximum diameter capacity.
▸ What's the difference between manual and automatic crankshaft polisher?
The manual polisher like the PV-2200 needs the operator controlling disc movement over the journal, regulating pressure and time by hand. The automatic has CNC programmed feed. Manual is cheaper, flexible for different crankshafts and lets the mechanic feel the finish quality. Automatic is faster in high production but costs much more and is less versatile for small machine shops with various part types.
▸ How does crankshaft polishing work in practice?
The crankshaft goes in the chuck plate and tailstock, rotating slowly (14-34 rpm). The felt disc with polishing compound spins at 780 rpm and the operator approaches the journals. The rotation difference and abrasive compound removes grinding scratches. The secret is constant pressure without forcing, otherwise it heats up and warps the part. The PV-2200 has controlled rotation that prevents this, leaving mirror finish ideal for the bearings.
▸ How long does the felt disc last on the polisher?
The felt disc lasts about 6 months to 1 year depending on usage. Heavy machine shops doing lots of crankshafts will replace more often. Signs for replacement: felt fraying, losing round shape or not achieving good shine even with fresh compound. The PV-2200 comes with Ø19.7x0.8 inches (Ø500x20mm) disc, but has optional various thicknesses available. Keeping the disc clean and using correct compound significantly extends service life.
