Grain is not easily to fall off, is lost, and not only increases the service life of diamond tool, and improve the utilization rate of diamond, thus
With preferably application prospect.
The foregoing is only a preferred embodiment of the present invention, is not intended to restrict the invention, for the skill of this field
For art personnel, the invention may be variously modified and varied.All within the spirits and principles of the present invention, made any to repair
Change, equivalent replacement, improvement etc., should all be included in the protection scope of the present invention.
