The grooving and cutting in the CNC machining plant of the part belongs to the turning application and is a relatively common machining process in the machining industry. In the entire grooving and cutting process, the selection of the knife and the use of aspects are quite elegant. So, today I will talk to you about cutting and grooving.
1. Select the tool
It is important to reduce the cutting force and the material savings when cutting the pipe, workpiece, and bar. Therefore, the blade should be as narrow as possible, and the groove shape can make the cutting narrower than the groove. This allows for good cutting control and surface finish.
2. How to apply
The blade should be as narrow as possible. This can help save material and reduce cutting force, and also reduce environmental pollution. If possible, avoid cutting to the center. Reduce the feed by 75% before cutting to the center of the workpiece, which maximizes tool life. The cutting process is stopped approximately 1 mm before the center of the workpiece, and the part will fall due to its own weight and length.
Cutting processing precautions:
1. Set the height of the cutting edge to a height of 0.1 to 0.2 mm above the center point.
2. Always use wet machining and ensure that enough cutting fluid flows to the tip.
3. The recommended machining is to use a fixed rotating tree to stabilize the life of the tool.
4. Cut as close as possible to the nip point.
5. When the cutting process is close to the center, reduce the amount of the feed to 1/2 to 3/1 of the original to avoid the impact when cutting.
2.1. Cut to pre-drilled hole
Be sure to drill deep enough to not affect the lateral forces. Forced blades with side sharp corners can cause blade cracking and inconsistent tool life.
2.2. Cut small diameter bar and cut thin wall tube
Try to use the smallest, sharpest blade to ensure the most possible force.
2.3. No flash cut
Use a right or left hand refining blade with a front corner to avoid or reduce flash. Note that the large front angle reduces the flash, but may result in a non-straight surface and may result in a worse surface finish and shorter tool life. Use the smallest possible front corner.

2.4. Cutting of pipe fittings
Use as narrow a blade as possible to save material, reduce cutting forces and reduce environmental pollution.
2.5. No burr cut
Use a right or left hand precision blade with a front corner to avoid or reduce burrs.
Therefore, when the machining of the CNC machining shop is carried out, when the force and the moving direction of the tool are the same, careful operation must be taken. To prevent the occurrence of the phenomenon of the knives and the broken knives, the loss can be reduced, and the tool must be reduced. The sharpening condition and the clamping situation are well done. It is necessary to adjust the various parameters of the machine tool so that all parts of the machine tool are good.
