Diamond wheel is the most hardest wheel used in Diamond Grinding Machine, it has the "invincible" ability, grinding ability is very tough, but the use of diamond grinding wheel is also still have to pay attention to some issues. To extend the service life of diamond grinding wheel. Diamond wheel is a valuable diamond tool, only used in the processing of high hardness materials, and should not be used to grind ordinary steel or other soft materials. The use of diamond grinding machine, the rigidity is better, the spindle selection accuracy is high (radial runout is not greater than 0.01 mm), and can make a trace horizontal feed.
But also should choose the appropriate amount of grinding. The following data for reference:
(1) wheel linear speed:
Metal bonding agent: ①10 ~ 15 * / s (dry grinding), ②20 ~ 35 * / s (wet grinding)
Resin binder: ①15 ~ 30 * / s (dry grinding), ②25 ~ 40 * / s (wet grinding)
(2) work-piece line speed: usually 10 ~ 15 * / min.
(3) grinding depth: grinding depth is smaller, or diamond grinding wheel wear quickly, and the grinding efficiency is not necessarily high. Generally 0.005 to 0.01 mm / oxygen stroke is appropriate. The finer the abrasive grain size, the smaller the grinding depth, especially when the coolant is not used.
In addition, the new diamond wheel to start using, in order to make it the correct shape (cylindrical roundness, flatness of the face), also need to be trimmed, dressing method available carbide wheel, or silicon carbide abrasive in the flat Metal plate or glass with manual grinding for dressing (for dressing wheel face).
In order to save diamond wheel, you can also use the natural dressing method, that is, the new wheel used for coarse grinding, to be worn to the correct shape, and then used for grinding. Grinding process found in the grinding wheel is not enough sharp or clogged phenomenon, you can also hand-held silicon carbide grinding wheel carefully work surface grinding wheel a little refit. Also need to pay attention to the following questions:
1. Surface operation problems;
In everyday use, many operators are always accustomed to operating the grinding wheel because of the energy that can be applied in this direction, which is actually a behavior that should be specifically prohibited in the operation of the grinder. According to operating procedures, the use of grinder grinding work-piece, the operator should stand on the side of the diamond wheel, not in front of the wheel to operate, so as to avoid failure of the wheel, the wheel out of or broken wheel flying out of wounding.
2. Side grinding problems;
In the daily use of the grinder, we often find that some operators grind the side of the grinder randomly, regardless of the type of the grinder, which is a serious violation of the safe operation rules behavior. According to the rules with the circumferential surface of the diamond grinding wheel should not be used to carry out the side of the grinding, the larger radial strength of the wheel, the axial strength is small, the operator is too large will cause the wheel broken, or even wounding, at The actual use of the process should be prohibited from such behavior.
3. Common problems
In actual day-to-day operations, this happens as well. Someone is trying to catch a job and grab a working time while they share the same grinder. This is a serious illegal operation and should be strictly prohibited. A grinder is not enough time, you can use to add grinder solution, absolutely not allowed to share a grinder.
4. hard to operate the problem
In the use of grinder, some operators, especially young operators, in order to grind faster, too much force, this is a very unsafe operating behavior. Any diamond grinding wheel has a certain strength, this is likely to cause the grinding wheel broken, or even fly out wounding, but also a prohibited behavior.
