Frequently Asked Questions
▸ What is a crankshaft polishing machine used for?
The crankshaft polishing machine is used for final finishing on crankshaft journals and pins after grinding. It removes microscopic scratches, leaves a mirror surface finish and ensures the necessary smoothness for proper bearing operation. The PV-1500 works with crankshafts up to Ø15.7x59 inches (Ø400x1500mm), using a Ø19.7 inch (Ø500mm) felt polisher at 780rpm, ideal for car, light truck and agricultural machinery engines.
▸ What is the maximum crankshaft size the polisher can handle?
The polisher can work with crankshafts up to Ø15.7x59 inches (Ø400x1500mm) maximum capacity. This covers most automotive engines, from compact cars to medium trucks. The machine has a Ø6 inch (Ø152mm) crankshaft chuck plate and 3hp motor for the polisher, ensuring sufficient power even for larger parts. Crankshaft rotation varies from 14 to 34rpm, allowing adjustment according to diameter and desired polishing type.
▸ What types of engines does this crankshaft polisher work on?
The PV-1500 handles domestic and imported car engines, light trucks, vans, pickups, agricultural tractors and industrial machines with crankshafts up to Ø15.7x59 inches (Ø400x1500mm). It works on both gasoline and diesel engines. With the standard Ø19.7 inch (Ø500mm) disc, it can polish from small journals to V8 engine pins. For specific applications, optional Ø15.7 inch (Ø400mm) and Ø23.6 inch (Ø600mm) discs are available.
▸ What is the difference between manual and automatic crankshaft polishers?
The manual polisher like the PV-1500 requires the operator to manually control the polisher movement and pressure on each journal. It allows greater process control and is more versatile for different crankshaft sizes. The automatic does the process alone after programming, being faster in series production. The manual is better suited for machine shops working with variety of engines, while automatic serves better for high volumes of the same type.
▸ How does the crankshaft polishing process work?
The crankshaft is fixed between the universal chuck and rotating tailstock, spinning from 14 to 34rpm. The Ø19.7 inch (Ø500mm) felt disc spins at 780rpm with polishing compound applied to the surface. The operator brings the polisher close to journals and pins, making longitudinal movements to ensure uniform finish. The polishing compound removes microscopic scratches from grinding, leaving a mirror surface. Process takes few minutes per journal, depending on initial condition.
▸ What is the lifespan of the polisher felt disc?
The felt disc lasts on average 6 months to 1 year in normal machine shop use, depending on frequency of use and type of polishing compound. Signs for replacement: felt too worn, hardened or with deep grooves that mark the crankshaft. The PV-1500 comes with standard Ø19.7x0.8 inch (Ø500x20mm) disc, but has options from 0.6 to 1.6 inches (15mm to 40mm) thickness available. To extend lifespan, clean the disc regularly and use only proper polishing compound.
