Graph sketch map of emery wheel of 1 turning nap pursues emery wheel of figuration of nap of 2 diamond gyro wheel uses nap figuration of nap of tool general emery wheel or long go wearing blunt surface layer, in order to restore the unit process of cargo bandling of the grinding function of working surface and correct geometrical figure. Correctly nap emery wheel, it is to increase grinding efficiency and the important segment that make sure grinding quality is indispensable. Emery wheel nap has turning commonly, wait for a method with diamond gyro wheel, grinding and rolling. Turning nap law with odd grain diamond (or the nap of diamond of King Kong pen that makes with finely diamond piece) regarding cutting tool turning as emery wheel is the nap method with the commonnest application. Installation is in normally in the diamond cutting tool on tool carrier perpendicular with the level two direction tilt each 15 ° of ～ of about 5 ° ; The contact of diamond and emery wheel is nodded should under emery wheel axes 0.

5 ～ 2mm, the diamond when nap makes shift of even low speed feed. The exterior surface roughness after requirement grinding is smaller, criterion feed speed should be jumped over low, if should achieve Ra0.

16 ～ 0.

The exterior surface roughness of 04µm, nap feed speed should under 50mm/min. Nap gross is commonly bosseyed 0.

1mm left and right sides, nap of move back and forth for many times. Thick repair cut it is greatly every time 0.

01 ～ 0.

03mm, essence of life is repaired be less than 0.

01mm. Law of nap of diamond gyro wheel is used eletroplate or the diamond gyro wheel that the method such as pulverous metallurgy sets many diamond grain in steel to pledge gyro wheel surface is made, rotate with certain rotate speed (Jie in order to reduce the relative speed) of gyro wheel and emery wheel, the emery wheel surface that rotates to high speed produces grinding and Zhan to control function, make emery wheel gains the incisive work face with be identical of gyro wheel face. Diamond gyro wheel makes complex, cost tall, but efficiency of wear well, nap is tall, comfortable at be in grinding of large quantities of the nap in estimating production are special figuration surface (if tenon of lamina of whorl, gear and turbine ages,wait) emery wheel. Law of nap of emery wheel grinding uses low speed revolving to exceed the arenaceous wheel pair that emery wheel of strong level carborundum and high speed rotate to grind, in order to achieve the goal of nap. Rolling nap law uses a group of hard alloy disc, You Bo disc of billow form white iron or the hard steel of temper by dipping in water that take groove piece suit and become gyro wheel, undertake nap to boil and squashing with emery wheel. Gyro wheel is installed commonly the operation is moved in begin of nap clamping apparatus, nap efficiency is tall, comfortable the nap at kibble emery wheel. CNC Milling
