Hardware Punch Precision Automotive Parts OEM Processing Quartet and Cylindrical 

About Product Description

1. Processing Difficult: This is a more complex processing workpiece,  It is clear that this part is round and square mixed molding, in the grinding process, the cube and cylinder concentricity grinding is 0.003, the machining accuracy of the R0.05 molding part, the slope and 0.1 slot is 0.005 mm, And smoothness of the surface is also the difficulty of the precision mold part. Another processing difficulty is EDM processing, such as: dimensional accuracy of 0.01 mm and surface finish control.

We are not afraid to face the difficult precision mold parts , because we have experienced engineers, ability and quality is our Kingrui best guarantee.

2. Application Material: SKH51 was used in this precision mold part. As we known, SKH51 has some special features, such as:  high red hardness, high wear resistance and cutting capacity, high impact toughness, fine grain uniformity, high toughness, etc.And this precision mold part. This precision mold parts are metal punch inserts, metal punch inserts require material hard, high impact resistance, wear resistance, so SKH51 choice is appropriate.

3. The Part Shape: Square and rounded union,this shape also gives us a certain degree of difficulty in processing.

4. Main Processing: Heat treatment, milling, grinding, wire cutting, discharge.
