Why do crankshafts/camshafts need polishing?

Crankshafts are generally composed of spindle and connecting rod journals. Crank, balance block, front and back end, etc., the material is made of carbon structural steel or nodular cast iron. A spindle neck, a connecting rod diameter and a crank constitute a crank, the number of in-line engine crankshaft crank is equal to the number of cylinders; The number of bends in a V-engine is equal to half the number of cylinders.

How to ultra precision processing bearing ?

Bearing super finishing, also known as super finishing, is a micro-grinding process. For high-precision bearings, usually the ring rolling surface and the working surface of the rolling body need to be ultra-finished.
Ultra-finish machining has different processing equipment, processing principles are not the same, in order to achieve the geometric accuracy requirements, surface quality requirements, it is necessary to consider the equipment, tooling, whetstone, grinding fluid, and even the grinding process bearing parts of the state.

What material can Virtifed CBN grinding wheel process?

Vitrified bond CBN grinding wheels are increasingly used in the fields of grinding micro-bearings in the inner circle (for magnetic tape, video recorder and office automation equipment), grinding cams or grooves, or honing automotive parts. This is because vitrified CBN grinding wheel or honing strip is different from resin, metal or electroplating bond CBN grinding wheel, it is particularly suitable for the above field of large-scale production needs. This paper mainly discusses the differences of CBN grinding wheel with different bond agents and their grinding effects, enumerate some practical examples of cubic boron nitride grinding tools with vitrified bonding agents and the selection methods of grinding parameters and grinding tools specifications.

How to achieve mirror surface roughness?

The surface roughness of the workpiece after grinding is Ra<0.01μm, and the light is like a mirror, which can image clearly, so it is called mirror grinding. The flatness of the grinding plane is not more than 3μm/1000mm. Surface machining of high precision and high added value parts requires mirror grinding.
