Double disc grinding requires high grinding fluid, good grinding fluid can improve the surface quality of workpiece and prolong the service life of grinding wheel. The selection of grinding fluid must meet the following requirements

Precision and ultra-precision grinding is not a simple machining method, it has formed a system engineering, its components are: machined materials, precision and ultra-precision grinding mechanism, precision and ultra-precision grinding machine, grinding wheel and dressing, workpiece positioning and clamping, detection and error compensation, working environment and human skills. Precision and ultra-precision grinding machine are the key to ensure the machining accuracy.

The advantages of spur gear and transmission: simple manufacture, easy assembly, direct engagement without synchronizer, and direct use of deep groove ball bearings for shaft end installation, basically without axial force.

Ceramic knife, Ceramic knife) is started using a new type of kitchen utensils and appliances in recent years, high purity superfine zirconia powder is used as raw material, under the condition of the high temperature of one thousand degrees, the spray granulation, isostatic pressing molding, precision machining and other process manufacturing, and has high hardness, strong corrosion resistance, good chemical stability, high wear resistance, high toughness and other characteristics.

Engineering ceramics occupy a very important position in the field of new materials for its high temperature resistance, wear resistance, corrosion resistance, good chemical stability and unique electrical, thermal, optical, magnetic and other functions.

Single sequence machining and compound machining can be used to grind crankshaft journal and connecting rod journal. Single sequence processing and composite processing of the main difference in the number of clamping, single sequence processing refers to the spindle journal and connecting rod journal grinding in different procedures for several clamping, and composite processing is a clamping, grinding spindle journal and connecting rod journal at the same time.
