Welcome one more day to the blog of Mecánica Curiel, your company. CNC machining trustworthy in Barcelona. In today's entry we want to talk to you about the appropriate cutting speed to cut in your center of CNC machining.
Cutting speed in machinery CNC It has a turning movement combined with a displacement movement. The combination of both movements is what causes the detachment of chips when they come into contact with the material along their movement.
The chip that we extract from the material has two functions, the first is to create a groove that allows us to separate one piece from the other, and the other function is to cool the tool.
While cutting a material CNC machined in Barcelona, friction and thermal change are generated. As the tool advances we manage to remove the pieces of the material, the chips. Any excess temperature in the tool can cause breakage, expansion or malfunction. You have to make sure in each CNC machining that the tool used is appropriate for the material to be machined.
The chip load factor (Cx) of each material will depend on its density and whether it is more or less high. There are tables that tell us what level of progress we can allow ourselves in each material.
If you want to make deeper passes, what is produced is a larger chip, so, to maintain the load established in the formula that belongs to the material being machined, what must be done is reduce the feed speed.
Another thing to keep in mind is vibration. When metal materials such as aluminum or brass are going to be cut, it is very important that the material is perfectly supported, since the vibration of the material during cutting means that the material is not being cut uniformly but rather that it will be bitten unevenly. stable, the material will overheat and end up breaking.
Excessive cutting speed
Excessive cutting speed can produce the following situations:
- Very rapid wear of the cutting edge of the tool
- Plastic deformation of the cutting edge with loss of machining tolerance
- Poor machining quality.
Cutting speed too low
Cutting speed that is too low may cause the following situations:
- Formation of input edge on the tool
- Negative effect on chip evacuation
- Low productivity
- High machining costs
The cutting speed is directly proportional to the hardness of the tool material, and inversely proportional to the hardness of the material to be machined.
