Cylindrical grinder is very common in mould factory and hardware processing factory, be manufacturing treatment commonly used equipment, apply very extensive. Between operation cylindrical grinder, very important to the choice of abrasive, the service life of the treatment quality to material and grinder is having the abrasive with the different right choice according to grinder very big impact. The steel qualitative roll with blame hard to temper by dipping in water or hard temper by dipping in water chooses cylindrical grinder corundum emery wheel; And roller of cold hard cast-iron roll, balata roller, copper, granitic roller uses carborundum emery wheel. Qualitative to different capable person steel pledges roller still should choose the corundum emery wheel that matchs to it, ability acquires taller grinding precision and exterior quality. If alloy steel roller chooses chromic corundum emery wheel, roller of heat-resisting alloy steel uses zirconium corundum emery wheel, to stainless steel roller should use single crystal corundum. The choice of granuality of cylindrical grinder emery wheel: Thick granuality is chosen when kibble (24~60) emery wheel. Fine granuality is chosen when essence of life is ground (60~100) emery wheel. 150 granuality emery wheel is used when accurate grinding. When grinding exceeding essence of life or mirror grinding, use small noodles or vermicelli made from bean or sweet potato starch commonly (W63~W14) emery wheel. The choice of hardness of cylindrical grinder emery wheel: Grinding roller side is better, emery wheel hardness should be jumped over when the choice soft. If emery wheel wears away too fast, explain the emery wheel that chooses to the roller place of specific treatment is too soft, can accept the following improvement measure: 1.
1.
Increase the linear velocity of emery wheel. 1.
2.
Rise procrastinate board fore-and-aft feed speed, namely workpiece every turn procrastinate board the 2/3~3/4 that fore-and-aft feed increases emery wheel breadth. 1.
3.
Lower the rate of roller. If adopt,apparent grinding effect had be notted obtain after afore-mentioned measure, explain emery wheel is too soft, not applicable, should choose a bit harder emery wheel. If when grinding roller, emery wheel is apparent suffocate suffocate or very dirty, passivation arenaceous bead falls off not easily, emery wheel is easy adhesion worry bit, occurrence burn of grinding roller face, pull hair, explain chosen emery wheel is too hard, can accept improvement of the following measure: 1.
1.
Reduce emery wheel linear velocity. 1.
2.
Raise roller rate. 1.
3 if adopt,apparent grinding effect had be notted obtain after afore-mentioned measure, explain emery wheel is too hard, should choose a bit softer emery wheel. 1.
4.
Outside the emery wheel that colophony bond chooses when the face of choice roller roller of bond of cylindrical grinder emery wheel divides mirror grinding, other grinding type all in order to use emery wheel of pottery and porcelain had better. CNC Milling
