Principle of computer gong tool alignment: plane tool alignment, put the tool on the tool rest, manually read the plane of the workpiece, calculate the depth and height, and run the machining height correction on the computer to compensate the height difference. This is the simplest NC machining method.

Features of computer gong:

1, parts have strong processing adaptability and good flexibility, and can be used to process parts with particularly complex contour shapes or difficult to control dimensions, such as mold parts and shell parts;

2. It can process parts that ordinary machine tools can't process or are difficult to process, such as complex curve parts and three-dimensional curved parts described by mathematical models;

3. Parts requiring multiple processes can be processed by one-time clamping and positioning;

4. The machining accuracy is high, and the machining quality is stable and reliable. The pulse equivalent of the numerical control device is generally 0.00 1mm, and the high-precision numerical control system can reach 0.1μ m. In addition, the numerical control processing also avoids the operator's operation mistakes.

5. The high degree of production automation can reduce the labor intensity of operators. Conducive to the automation of production management;

6, high production efficiency, CNC milling machines generally do not need to use special process equipment such as special fixtures, and only need to call the processing program stored in the CNC device, clamp the tool and adjust the tool data when replacing the workpiece, thus greatly shortening the production cycle. Secondly, the CNC milling machine has the functions of milling machine, boring machine and drilling machine, which makes the working procedures highly concentrated and greatly improves the production efficiency. In addition, the spindle speed and feed speed of CNC milling machine are stepless, which is beneficial to choose the best cutting parameters.
