Where do you need to pay attention to the harden of processing CNC precision parts?

Release time:2019-11-29 16:03:00  Browse times:

Dongguan pengshun mechanical and Electrical Co., Ltd. is a professional company specializing in precision parts processing, complex parts processing, titanium alloy parts processing, Dongguan CNC precision parts processing and non-standard parts processing, focusing on semiconductor, new energy, medical treatment, photography and optical communication and other fields. What details should be paid attention to in the hardening of precision parts?

1. The influence of cutting tools on the machining of Dongguan CNC precision parts. In the process of machining, cutting tools are indispensable. But the shape of the tool has a great influence on the hardening effect. The hard layer of cold work will be affected by the rake angle, edge fillet and tool wear. If the front angle of the tool decreases, or the wear of the back edge increases, the depth and hardness of the hard layer will also increase.

2. The influence of raw materials on the processing of Dongguan CNC precision parts. For example, if the hardness of the processed material is small, the greater the plasticity is, and the hard level of cold work is crucial. In CNC precision aluminum parts processing, because the hardness of aluminum is small, it must be specially considered.

3. The influence of cutting quantity in the process of machining. In the machining of Dongguan CNC precision parts, the hardness of cold work is affected by the feed rate and cutting speed of the tool. When the contact time between the tool and NC machining workpiece becomes shorter, the cutting speed increases, the hard layer and hardness of cold work are reduced, and the level of plastic deformation is also reduced. If the feed speed is increased, the surface cold hardening level is increased, and the plastic deformation level is increased.

What details should be paid attention to the harden of precision parts?


1.The impact from the CNC tool. The cutting tools are indispensable in the process of machining,but the shape of the tool has a great influence on the effect of hardening.The hardening layer of cold work will be affected by the tool's front angle, rounded edge angle and tool wear.If the front Angle of the tool decreases, or the wear of the back increases, the depth and hardness of the cold working hard layer will increase accordingly.


2.The impact from the raw material.

For example, the hardness of the processed material is small, the plasticity is greater,the level of cold work is critical.

In the processing of CNC precision aluminum parts,we must take special consideration because of the hardness of aluminum is small.


3.Influence of cutting amount during machining process.

During the CNC precision parts machining, cold work hardness is affected by the tool feed and cutting speed.When the tool and workpiece contact time becomes shorter, cutting speed increases,then the cold work hard layer and hardness are reduced, the level of plasticity deformation is also small.If the feed speed increases, the level of surface cold hardness increases, and the deformation of plastic level increases.
