Stay Parts processing In process ， The hardness of parts is a lot Parts processing Manufactor Most concerned 。 Such as Aluminum processing factory We attach great importance to the problem of hard parts ， This is also the reason why many customers choose aluminum profiles as materials 。 If the hardness is not up to the customer's standard ， Such products can only be treated as waste products 。

　　 For most Parts processing Manufactor Speaking ， Influence Parts processing The key factors for cold work are as follows ：

　　1、 Impact from processed raw materials 。 The processed raw materials directly affect the strength and hardness of the parts 。 Customer Stay When selecting raw materials to be processed ， We have determined the hardness of the parts 。 If the hardness of raw materials to be processed is small ， The greater the plasticity ， The more important is the hard level of raw material cold working 。 Parts processing Manufactor Stay And Customer When communicating materials ， Usually tell the customer in advance 。

　　2、 Influence from tool shape 。 Parts processing Manufactor All understand ， Parts processing Cannot leave the tool ， And the front angle of the tool 、 Edge fillet and wear of the back edge of the tool ， It has a great influence on cold working hard layer of parts 。 The hardness and depth of the hard layer decrease with the rake angle of the tool 、 The wear of cutting edge and rear edge increases with the increase of wear 。

　　3、 Influence from cutting parameters 。 Change of feed rate and cutting speed ， Stay Parts processing Cold work In process ， Great influence on strong hardness 。 When the feed speed of the tool increases ， The probability of plastic deformation is high ， Surface cold work hardness level increased 。 If the cutting speed of the tool increases ， Tools and care Parts processing Shorter contact time of workpiece ， The probability of plastic deformation is small ， The hardness and hardness of the hard layer are reduced 。

　　 Therefore ， Stay Parts processing In process As long as the above factors are properly handled ， Parts processing Manufactor You don't have to worry about tough parts 。
