What causes Milling Cutters to heat up abnormally?

Milling Cutter as a key tool for metal cutting processing, its working condition directly affects the processing quality and efficiency. Abnormal heat will not only accelerate tool wear, reduce machining accuracy, and in serious cases, even lead to tool chipping scrap. So you know what are the reasons for milling cutter abnormal heat? The following is the sharing of the editorial of Zhongye Da, take a look.

Milling Cutter in cutting abnormal heat, the essential reason is mostly due to the cutting process heat generation and distribution of the balance is broken.

First, the parameters and tool adaptation problems

Milling Cutter cutting parameters will increase the heat, such as too high a speed to exacerbate the friction, feed too much ambient deformation of the cutting layer heat. Cutting tool material and processing materials do not match, such as processing high hardness materials with poor red hardness of the tool, easy to soften the wear to form a vicious circle. Inappropriate coating will hinder heat dissipation.

Second, the process and equipment impact

Cutting process defects hinder heat dissipation, dry cutting chip winding, cooling medium error may make the milling cutter heat. Poorly designed tool chipformer can lead to chip accumulation. Machine tool spindle runout or workpiece clamping instability triggered by vibration, will also cause localized overheating of the cutting edge.

Third, the role of material properties

The material's own characteristics will also exacerbate the heat, such as cast iron white mouth organization, welded parts of the internal stress concentration area, will increase the milling resistance, in the organization of the uneven area, the heat is more likely to be concentrated in the edge.

Optimization direction

To solve the milling cutter abnormal heat needs multi-dimensional synergy. Adjust the speed and feed according to the material characteristics, and choose the appropriate tool material and coating. High-pressure internal cooling can be used to improve cooling, optimize the design of the chipformer. And check the milling cutter equipment precision and clamping stability, if necessary, the material annealing pretreatment.

In summary, systematic optimization of the whole process of processing, not only to extend tool life, but also to enhance the overall efficiency of metal cutting, and promote the development of manufacturing quality. For more information, feel free to consult with Zhongye Da.
