How to avoid the formation of chip deposits in fully automatic pipe cutting machines?

Measures to avoid the formation of chip deposits in fully automatic pipe cutting machines:  

    1、Increase the front angle of the tool、The front of the grinding tool、Using cutting fluid,Both can reduce cutting deformation and friction,Avoid the formation of debris tumors。

    2.Work hardening
Machined surfaces,Its hardness has increased、The phenomenon of reduced plasticity,Called work hardening。The depth of the hardened layer is0. 07-0.5mmbetween,The hardness is the original hardness of the deformed material on the processed surface of the material1.2-2times。

    3、The fully automatic pipe cutting machine adopts high-speed or low-speed cutting。Practical proof,Using less than2m/minOr higher than100m/minCutting speed of,When cutting medium carbon steel,It will not produce debris tumors。Under these two conditions,The friction coefficient between steel and tool materials is relatively small,Therefore, it is not easy to produce debris tumors。When using a fully automatic pipe cutting machine for medium speed cutting,The temperature in the cutting area precisely increases the friction coefficient between the steel and the tool material,So it is easy to produce debris tumors。The temperature in the cutting area is300℃Left-right timing,The height of the debris accumulation tumor is the highest。  

For surfaces that need to be further cut,Due to the presence of a hardened layer,Increased the difficulty of the next cutting。Based on the above reasons,Efforts should be made to minimize work hardening during cutting。 Hardening layer generated during cutting,Its hardness and depth are very uneven,And often produce small cracks。This is detrimental to the quality of the processed surface。When the fully automatic pipe cutting machine operates at low or high cutting speeds,The temperature in the cutting area is also low or high。
