How to cut off parts in CNC machining factories in a short period of time
How to learn cutting in CNC machining factories for parts in a short period of time!
The slotting and cutting in CNC machining factories belong to turning applications and are common machining processes in the machining industry. Throughout the entire cutting and slicing process, there is a great deal of attention paid to the selection and use of knives. So, today we will talk about cutting and slotting.
Cut off:
1. Choose a cutting tool
Reducing cutting force and saving materials are important when cutting pipes, workpieces, and bar materials. So, the blade should be as narrow as possible, and the groove shape should make the cutting narrower than the groove. This can achieve good cutting control and surface smoothness.
2. How to apply
The blade should be chosen as narrow as possible. This can be beneficial for saving materials and reducing cutting force, as well as reducing environmental pollution. If possible, avoid cutting to the center. Reduce the feed rate by 75% before cutting to 2mm from the center of the workpiece, which can greatly optimize the tool life. Stop cutting approximately 1mm before approaching the center of the workpiece, and the part will fall off due to its own weight and length.
Precautions for cutting processing:
1. Set the height of the blade tip at a point 0.1~0.2mm higher than the center point.
2. It is necessary to use wet machining and ensure sufficient cutting fluid flow to the cutting edge.
3. It is recommended to use a fixed rotating tree for stable tool life during processing.
4. Cut as close as possible to the clamping point.
When cutting near the center, please reduce the feed rate to 1/2 to 3/1 of the original to avoid impact during cutting.
2.1. Cut off to pre drilled hole
Be sure to drill deep enough not to affect the lateral force. Blades subjected to force at sharp edges may cause blade cracking and inconsistent tool life.
2.2. Cutting off small diameter bars and thin-walled tubes
Try to use narrower and sharper blades to ensure maximum force is generated.
2.3. No flying edge cutting
Use a right or left hand precision grinding blade with a front angle to avoid or reduce burrs. Pay attention to reducing burrs with a large rake angle, but it may result in uneven surfaces and may lead to poorer surface finish and shorter tool life. Use the smallest possible front corner.

2.4. Cutting of pipe fittings
Use blades as narrow as possible to save materials, reduce cutting forces, and minimize environmental pollution.
2.5. Non burr cutting
Use precision blades with front corners on the right or left hand to avoid or reduce burrs.
So, when machining in a CNC machining factory, when the force and direction of movement of the tool are consistent, careful operation must be carried out to prevent the occurrence of tool stabbing and breakage, which can reduce certain losses. In addition, it is necessary to do a good job in the grinding and clamping of the tool, and adjust all parameters of the machine tool to ensure that all parts of the machine tool are in good condition.
