The final operation to obtain the desired geometric characteristics, as well as to recreate the cutting properties lost due to wear of the teeth, is the sharpening of the cutters.
Correctly executed sharpening or finishing, increases the durability of the cutter and thus reduces the consumption of the cutting tool. When using it, it is not recommended to bring cutters to wear values that exceed the approved values. Therefore, it is necessary to monitor the condition of the cutting edges and carry out the sharpening of the cutters in advance, without allowing too much wear or significant tooth breakage.
Our company offers to grind and refine the face mills with a diameter of 80..630 mm on the semiautomatic device VZ-652F2. Sharpening of the main surface of the milling cutter is performed by the end face of the grinding wheel with or without use of a cooling liquid. Sharpening of the diamond circle face, carried out with cooling, is combined with electro erosive correction. Semiautomatic and separately located equipment is installed on the foundation or concrete cushion and, if necessary, attached to the foundation. Depth of placement depends on the ground.
- Automatic milling cutter (semi-automatic mode);
- Sharpening with feed per each revolution;
- Sharpening with filing on the tooth.
To sharpen the back plane of the milling cutter, it is first necessary to install it so that the auxiliary edge assumes a horizontal position and the milling axis is inclined in the vertical plane by the amount of the front corner of the auxiliary cutting edge.At the end of the process, the cutter must be examined for chips, cracks and other defects, and also check the roughness of the base of the treated surface.Video semiautomatic CNC Grinding Machine For Face Mills VZ-652F2
