Bearing grinding knowledge: the secret of success dressing grinding wheel

The key factors that can improve the grinding wheel grinding performance is good cosmetic and sharp ( Known as dressing) Tools and skilled finishing skills. In fact, a high quality finishing grinding wheel dressing tools and proficiency skill of the operator, can always keep grinding wheel has high grinding performance. Rather than relying only on buying so-called good grinding wheel. This is very important, because the shop can't according to each person, equipped with special grinding wheel. A sharp is a transferred superhard abrasive grinding wheel grinding grain of sharp grinding process. In this process, need to remove the grinding grain between binder and blunt grinding wheel grinding grain, make strong grinding performance of the grinding wheel grinding grain of prominent binder, form a sharp cutting edge. Repair the sharpness must also from the pores on the surface of the grinding wheel, remove tiny material, prevent enlargement of the grinding force acting on the grinding wheel, grinding wheel on the grinding force increases, will cause vibration and cause parts surface burn. Without the proper repair sharp, even the best grinding wheel is not likely to get consistency processing parts with high quality and size. In fact, when you invest in the high quality of the grinding wheel, in order to obtain high grinding performance, good finishing them it is very important. Plastic can be said to be part of preparations for grinding wheel, it with ordinary grinding wheel repair sharp at the same time. Two process for superhard abrasive grinding wheel, is separately, first for plastic wheel. In the use of superhard abrasive grinding wheel grinding, plastic surgery is the use of plastic tools or roller, repair the sharpness is often using a trim stick, ceramic bond upon the completion of the plastic, for dealing with sharp grinding wheel. Before dressing of grinding wheel's including plastic and sharp, main shaft bearing in a certain temperature ( As usual grinding wheel grinding state) Is very important. This can avoid damage parts geometric shapes and abnormal wear of grinding wheel and the dressing tools. For dressing tools must be handled with care, generally speaking, qualitative hard, wear-resisting, but because it is very brittle materials, diamond and the tiny crack and breakage caused by slight collision, force is very sensitive. Because the diamond dresser itself is a tool, need to keep very sharp. Use a dulling the dressing tools to trim surface of grinding wheel, grinding wheel dull. In order to maintain a high quality and the sharp diamond dressing tools, at regular intervals, twirling need 1/8 single point or finishing tool with a cone tip. Number of revolution can be decided according to the modification situation, according to the experience, at least rotating once a day. For chisel head and forming the dressing tools, general need 180 ° before they dull rolling again. Most of the cylindrical grinder is put parts and grinding wheel in a horizontal line. The highest point of the cylindrical parts with cylindrical grinding wheel/grinding wheel contact points, the highest known as parts diamond dressing tools should be as much as possible in the near parts/grinding wheel dressing grinding wheel contact points. For internal grinding machine used grinding wheel, diamond dressing tools close to the highest point of the cylindrical grinding wheel ( The hole when the parts/grinding wheel contact points) Repairing it is more important. To trace dressing to reduce the repairing time, as there is always a kind of want to choose some bigger in addition to the temptation of depth. This is a wrong idea. Must choose the most appropriate repair in addition to the depth of grinding wheel dressing. Choose too large in addition to the depth, can produce high cutting temperature, reduce the service life of the dresser, will also useful wheel layer removal. The end result is to make the dresser and grinding wheel is damaged, both counterproductive. Optimum amount of modification after repairing by several times in addition to, can restore the geometry of a grinding wheel, and can produce good grinding blade just as guidelines. Using a single point of dressing tool, should with 10 - 15 o axis Angle contact grinding wheel diameter direction. This will lead to a single point of dressing tools in the regular rotation, produce a sharpening effect. With multipoint contact dressing tools don't need to tilt the Angle. Instead of using dressing tool of the entire face and the grinding wheel surface contact.
