To improve the performance of the largest grinding wheel grinding key factors is good plastic and the sharp (appellative and trim) tools and skilled shaping skills. In fact, a high quality dressing tools and mastering dressing grinding wheel skills of the operator, can always keep the grinding wheel with high performance. And not just rely on the purchase of the so-called good grinding wheel. That is very important, because not everyone work according to the workshop, equipped with special grinding wheel.
The sharp is a super hard grind grain of grinding wheel grinding grain of the grinding of sharp process. In this process, the need to remove between the grits combination agent and grinding wheel grits blunt, have very strong performance of the grinding wheel grinding grain of outstanding combination agent besides, forming sharp cutting edge. The sharp must also from the surface of the grinding wheel vent, removing tiny materials, in the role of the grinding wheel to prevent the grinding force increases, the grinding wheel grinding force increases, will cause vibration and cause parts surface burn.
Without the proper fix sharp, even if is the best of the grinding wheel is impossible to obtain the processing components of high quality and size consistency. In fact, when you throw in the high quality of the grinding wheel, in order to get high grinding performance, good nap they appears very important.
Plastic can say is part of the preparations for grinding wheel, it and ordinary grinding wheel to the practice of sharp simultaneously. For super-hard abrasive wheel, two procedure is taken separately, first to the grinding wheel is shaped. In the use of ultra hard abrasive wheel grinding, plastic is to use plastic tools or roller, the sharp is often use a ceramic combination agent the nap of great, the plastic, after the completion of the grinding wheel to sharp processing.
In the grinding wheel including plastic and fix the nap of sharpness before, guarantee the spindle bearing in a certain temperature (such as the grinding wheel grinding usually state) is very important. This prevents damage geometry and parts of the grinding wheel and dressing tools of abnormal wear. To trim the tools used must be handled with care, because it is general by qualitative hard, wear-resisting but and crispy diamond material is made, and the because of slight collision, force cause tiny crack and breakage are very sensitive.
Because the diamond plastic itself is a knife, need to keep very sharp. Use a grinding of blunt dressing tools to fix the grinding wheel surface, can make the grinding wheel dull. In order to maintain a high quality and the sharp diamond dressing tools, every time, need 1/8 single point or belt rotating enclosure cone pointed dressing tools. According to the number of rotation to trim, according to experience, at least once every day rotation. For the head and molding chisel dressing tools, usually takes worn them before blunt in 180 ° rolling again.
Most cylindrical grinder is will parts and grinding wheel in a horizontal line. Parts of the highest point and the grinding wheel round round the highest point of the parts/contact point is called grinding wheel, diamond dressing tools should as far as possible in parts/grinding wheel contact point to place dressing grinding wheel. In with grinding wheel to round grinder, grinding wheel, diamond grinding tools will be close to the round high (namely grinding holes parts/grinding wheel contact point) for renovation, this is more important.
Take trace nap
To reduce nap time, as if there is a kind of want to choose a big fix in addition to the temptation of some depth. This is a kind of wrong ideas. Must choose the most suitable to the practice of depth to the grinding wheel except for renovation. Choose too large in the depth, and will produce the high cutting temperature, reduce the shaping of the service life, will also be useful grinding wheel layer resection. The end result is that the dressing grinding both damage, just the opposite.
The best of the several times for shaping the except, already can restore the geometry of the grinding wheel, and can produce good grinding just logic as the criterion.
Use single point dressing tools, should be with 10-15 o of axis line gradient contact the diameter of the grinding wheel direction. This will make the single point dressing tools in regular turns, produce a sharpening role. With more contact with dressing tools don't need to tilt the Angle. Instead of the whole end with dressing tools with grinding wheel surface contact.
