Higher cutting speed can reduce cutting forces

will increase the cutting speed cutting force, thus accelerating tool chipping failure, so a diamond cutting tool machining should not be too low.
Should be avoided in the stationary state the diamond tool and workpiece or other hard object, tool edge to prevent bruising. Operator  granite polishing pad nails and fingerprints easily entrained sand and other hard objects, scratching with nails or fingers directly blade diamond blade may be damaged. Diamond tool knife should be used to detect and adjust optical instruments and other non-contact measurement method.
Should be used plus the amount of alcohol or acetone cotton cleaning diamond tools. Put the tool when not in use rubber or plastic protective sleeve, and placed in a separate knife box.
Using the straight line wiper diamond tools for cutting mirror, requiring deputy angle less than a few minutes, and the tool that may arise during the installation of the installation error of 1 °, so the need for pre-processing tool for the knife, by adjusting the  cutting tools light repair tool edge and parallel feeding direction, in order to get the best surface roughness. The knife is as follows: First, a short machined on the workpiece surface, and then in the 10 to 30 times under the microscope to adjust the tool so that the wiper with a new machined surface of the mirror parallel. Since parallelism higher, and therefore must be patient and repeated fine adjustments. It should be noted: Unscrew the knife lever clamping screw may produce slight rotation of the cutter knife lead to failure.
Because straight wiper blade tool for time-consuming process, so for some precision cutting can be less demanding of the carbide tipped saw blade  mirror radius of 10 ~ 30mm arc cutting tool instead of a straight line wiper tool. The shape of this circular blade cutter tools with contact lenses similar, but reduces the posterior horn, increasing the nose radius. Using this tool the knife is not only simplifies the process, and when an arc worn, after a slight rotation of the tool may be used for another new arc, thereby increasing the tool life. Precision circular single-crystal diamond cutting tool is machining the necessary tools concave mirror.
