How to achieve mirror surface roughness?
2022-08-25The 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.

The difference between diamond sanding belt and diamond grinding belt
2022-08-04Both diamond abrasive belts and diamond grinding wheel are the cumulative effect of micro-cutting of the “micro-edge cutting tool” with high speed — abrasive particles, so their grinding mechanism is roughly the same. However, due to the different characteristics of sand belt composition and use mode, the grinding of diamond polishing belts is different from diamond wheel grinding in terms of both grinding mechanism and comprehensive grinding performance. The main performance is as follows

How to select grinding fluid in different grinding methods?
2022-08-01During metal grinding process, it is very important to choose the right grinding fluid in order to obtain the ideal machining accuracy and surface quality. Different metal grinding processes have different processing phenomena and different requirements on grinding fluid, so the grinding fluid used is more different.

The difference between hubless dicing blade and hub type electrofromed dicing blade ?
2022-07-18The diamond dicing blade is a kind of diamond cutting disc that needs different specifications for different models. Thin diamond cutting disc are usually used for slotting or cutting. In order to distinguish different cutting disc, thin diamond cutting disc are divided into ” hubless dicing blade and hub type electrofromed dicing blade”.

How to achieve high precision grinding crankshaft
2022-07-13Crankshaft is also a very unique part, no other part processing requires so many different processes, it is thin and long, the materials used in poor machining performance. Among them, the accuracy of thrust surface (including thrust journal and width) is more and more high, and R. A significant characteristic of thrust surface is that its contact area is much larger than that of other shaft collar sides, and the accuracy requirements are also much higher. Vitrified CBN grinding wheel is the ideal tool for crankshaft grinding, control is very sensitive, preventing burns during grinding.

How to high precision rotor grooving?
2022-06-30The rotor is a key part of the vane pump/motor. The material is 38CrMoAlA and the surface of the rotor groove is nitrified. Because the size accuracy, shape and position tolerance and surface roughness of this part are high requirements, the groove is narrow and deep, so the grinding wheel should be considered to have chemical inertia and high hardness, not need dressing in the process of use, so the selection of vitrified or electroplated CBN grinding wheel is more suitable.

Do you know how centerelss grinding work?
2022-06-22Centerless grinding is on centerless grinding machine, which interacts with regulating wheel and supporting plate to grind workpiece cylinder. During grinding process, no spindle or fixture is used to locate and secure the workpiece, workpiece is between the grinding wheel and the regulating wheel, supported by the support plate below, and the regulating wheel drives the cylindrical workpiece to rotate on the pad iron. Centerless grinding can also be used for inner circle grinding. During machining, the outer circle of the workpiece is supported on the roller or the supporting block, and the workpiece is driven to rotate by the eccentric electromagnetic suction ring. The grinding wheel extends into the hole for grinding. Centerless inner circular grinding is usually used to grind inner groove of bearing ring on special grinding machine for bearing ring.
