Why is the carbon fiber milling cutter easy to entangle chips?

In the carbon fiber machining scenario, milling cutter chip entanglement is a headache for many practitioners. It not only slows down the machining rhythm, but also may affect the machining accuracy, damage the tool, and even lead to the scrap of the workpiece. So, why is the фрезель из углеродного волокна especially easy to wrap chips? Today, we will come and Zhongye da editorial together to understand.

First, the root cause

Свойства материала

First of all, carbon fiber composite material consists of carbon fiber reinforcement and resin matrix. High hardness, high brittleness of the carbon fiber is easy to produce short chips, and the resin matrix is softened by heat viscosity, the chips will be bonded into a mass winding фрезель из углеродного волокна, сочетание его твердых и мягких характеристик для увеличения сложности удаления чипа.

Structural design defects

Во -вторых, малые и плохого и плохого держателя чипсов предотвращают своевременные сбросы чипов, а тупая передняя кромка усугубляет деформацию экструзии материала, которые представляют собой два фактора, которые увеличивают риск запутывания чипа.

Improper processing parameters

One point that cannot be ignored is that too low a rotational speed causes cutting heat to accumulate, and too slow or too fast a feed will lead to excessive chip fragmentation or delayed discharge, and too large a depth of cut exceeds the capacity of chip removal, all of which will lead to chip entanglement.

Second, chip removal solutions

Optimize the design of cutting tool: Adopt spiral milling cutter with large chip holding groove, sharpened with high precision, and coated with DLC anti-adhesion coating.

Регулировка параметров обработки: разумно увеличивает скорость вращения, чтобы уменьшить тепло режущего, соответствовать характеристикам материала, чтобы установить скорость подачи и использовать слоистую резку для управления количеством генерации чипа.

Reinforcement of auxiliary measures: use lubricant-containing cutting fluid to reduce temperature and remove chips; during dry machining, blow the cutting area directionally by high-pressure air.

In short, фрезель из углеродного волокна chip entanglement, the nature of a variety of factors superimposed on the results. We want to solve efficiently, as long as these methods to eat through, live, in order to make carbon fiber processing chip removal smooth, efficiency, precision double enhancement, do not have to worry about chip entanglement.
