CNC Machining Description

The Features of CNC Turning

1. CNC lathe can operate automatically the main shaft speed change, positive and negative rotate, start or stop, feeding and moving along the two coordinate direction, loose, transposition and clamp the knife rest, control the cutting fluid, etc.

2. The feeding of turning tools should establish relationship with the rotating of main shaft. Because the CNC turning is calculated by the pulse equivalent that the turning tools moving along the feeding direction when the main shaft rotate a circle.

3. Because the design drawing of components are indicated and measured by diameter data, to improve the precision of radial dimension, make the programming and measuring easier, the pulse equivalent on X axis will be half of on Z axis.

4. When use horizontal type CNC lathe to machining components, to ensure the machining precision and surface quality, the main shaft should have a large speed adjustable range. It can use both constant surface speed and constant rotate speed for machining.

5. The workblank for CNC turning is always rough blank and die forging. The machining allowance is large. So the CNC lathe will have different fixed cycle function. It can process kinds of turning machining.

CNC Turning Route

1. Single row slot cutting: For annular slots with small width and depth dimensions, the cutting tool with equal width can be used to cut and cut the groove once. Generally, the tool is positioned rapidly along the z-axis direction and is processed along the X-axis direction. After cutting into the bottom of the groove, the tool can be stopped for a short time by using the pause instruction to trim the shape accuracy of the bottom of the groove.

2. Deep slot turning: The cutting route of deep groove shall adopt the method of sub-feed. After cutting into the workpiece at a certain depth, the cutter shall stop and return to a certain distance, so as to achieve the purpose of chip cutting and chip removal and avoid the phenomenon of tying and breaking the cutter. Note that the processing route only moves in radial (X direction) and back.

3. Wide-slot turning: When the precision requirements of turning side and groove bottom are both high, the method of row knife should be adopted for rough turning. Then, the fine cutting groove shall be rolled from one side of the groove to the groove bottom. When determining the finishing route, pay attention to the change of the cutter location. The distance of axial movement is not equal to the width of the groove, but the difference between the bottom of the groove and the width of the cutter.
