Why is copper hard to grind ?

Copper has good ductility, it is easy to cause blockage of pores, and the grinding wheel loses heat dissipation capacity, which in turn causes burns or expansion and deformation of the workpiece, which is one of the materials that are difficult to grind.

Why is grinding more accurate than turning or milling?

The grinding mechanism is completely different with cutting.

In cutting,using the tool cut into workpiece material so the material deforms then breaks.

Application of Vitrified Diamond Wheel in Thermal Spraying Industry

Vitrified diamond grinding wheel not only has the wear resistance of metal bond and the porosity of vitrified bond. There are many advantages: high abrasion rate, minimal bond/workpiece interaction, excellent chip and coolant carrying capacity, good sand fixation ability and tool life, reduce surface damage to the self-sharpening behavior of the work piece, and change the grinding wheel Grit Selection and customization of hole structure.

The influence of raw materials on grinding wheel life

Most of the vitrified diamond grinding wheels we produce are used for the grinding and polishing of precision PCD tools. Generally, the quality of the cutting edge of PCD tools requires 50 times magnification without chipping, and the high requirements are 200 times magnification without chipping, Even 5 μm edge accuracy

Compensation method for grinding wheel dressing

The accuracy of the work piece depends largely on the consistency of the process system state.After dressing the layer thickness decreases and the grinding wheel local changes to the designated calibration position, which leads to the change of the state of the whole process system, so the size consistency cannot be guaranteed.Therefore, it is very important to compensate the grinding wheel after dressing.

How to solve the problem of superalloys machining?

Superalloys refers to a kind of metal material based on iron, nickel and cobalt, which can work for a long time under high temperature above 600℃ and certain stress. With high temperature strength, good oxidation and corrosion resistance, good fatigue performance, fracture toughness and other comprehensive properties. Superalloys is an important material widely used in aviation, aerospace, petroleum, chemical industry and ship.

Influence of grinding wheel blockage on cutting force and grinding wheel vibration

Cutting Force: The cutting force of a grinding wheel is caused by two functions: chip formation and friction;  It is generated by physical contact between the grinding wheel structural parts and the workpiece. Under the specified conditions, in the total cutting force, the cutting force related to friction is much larger than that related to chip formation. Because the two cutting forces are associated with each other during chip formation, they are not easily distinguished. Less friction can provide a freer cutting force and reduce surface heat and blockage of the grinding wheel. The cutting force determines the lifespan, abrasion resistance, energy and other grinding standards.
