Cone rolling machine

We are a professional manufacturer of cone rolling machines with over 10 years of industry experience. Today, we would like to introduce to you:

There are various factors that affect the cutting temperature of the cone rolling machine, and these factors collectively affect the cutting area, leading to changes in cutting temperature. The following is a detailed analysis of these factors:

1. Cutting parameters

The cutting speed is the most important factor affecting the cutting temperature of the cone rolling machine. When the cutting speed increases, the amount of metal involved in deformation per unit time increases, the power consumption increases, friction and plastic deformation intensify, the heat generated increases, and the heat dissipation time decreases, resulting in a significant increase in cutting temperature. When the feed rate increases, the thickness of the cutting layer increases, and the heat generated also increases accordingly. However, compared to cutting speed, increasing the feed rate has a smaller impact on heat dissipation, so the temperature rise is relatively small. The effect of back cutting amount on cutting temperature is relatively small. This is because the change in the amount of back cutting has a limited impact on the heat dissipation area, so the temperature change is not significant.

2. Workpiece material

The higher the strength and hardness of the workpiece material, the more work is consumed during cutting, and the more cutting heat is generated. Therefore, the cutting temperature of the cone rolling machine is higher. The higher the thermal conductivity of the workpiece material, the more heat is transferred through the chips and workpiece, and the faster the cutting temperature decreases. On the contrary, materials with low thermal conductivity are less likely to dissipate cutting heat and have relatively high cutting temperatures.

3. Geometric parameters of cutting tools

Increasing the rake angle of the tool can reduce cutting deformation, thereby reducing heat generation. Meanwhile, increasing the rake angle can also improve the heat dissipation conditions, which is beneficial for reducing the cutting temperature of the cone rolling machine. But when the current angle exceeds a certain range (such as 18 °~25 °), the heat dissipation conditions become worse due to the reduction of the tool wedge angle, and the influence of the rake angle on the cutting temperature will weaken. The reduction of the main deviation angle will increase the working length of the cutting edge and the tip angle, thereby improving the heat dissipation conditions and reducing the cutting temperature.

4. Tool wear

After the tool wears out, the cutting edge becomes dull, which will intensify the friction and deformation during the cutting process, leading to a sharp increase in the cutting temperature of the cone rolling machine. Therefore, the wear of the cutting tool has a significant impact on the cutting temperature.

5. Cooling conditions

The use of cutting fluid can directly absorb and remove heat from the cutting area, effectively reducing the cutting temperature. The lubricating effect of cutting fluid can also reduce friction, further reducing the generation of cutting heat.
In summary, the cutting temperature of the cone rolling machine is influenced by various factors such as cutting parameters, workpiece materials, tool geometry parameters, tool wear, and cooling conditions. In the actual machining process, these parameters and conditions should be adjusted reasonably according to the specific situation to control the cutting temperature, improve machining quality and efficiency.
