When grinding the round mold, the following points need to be noted

 

The selection of abrasives should be based on the mold material to choose the appropriate hardness and particle size, to avoid hard or too fine abrasives to cause damage to the mold.

When grinding, apply uniform force, do not exert too much force, so as not to cause uneven mold surface.

The grinding direction should be perpendicular to the surface of the die to avoid grinding marks during the grinding process.

During the grinding process, it is necessary to ensure that the mold surface temperature is consistent to avoid unnecessary damage caused by local overheating or undercooling.

After grinding, the surface of the mold should be cleaned to ensure that the surface is smooth and without wear marks.

In addition, it is also necessary to understand the characteristics of the mold material and its requirements for the wear resistance and hardness of abrasives and abrasives, and to ensure that the operator has sufficient grinding skills and safety awareness.

Talk about the causes of loss in precision mold discharge machining?

 

Die discharge machining, also known as EDM or electroerosion machining, is a special processing technology that is widely used in die making and machining industries. The causes of the loss during mold discharge machining can be summarized in the following aspects:

A. Material problems:
Poor material quality, insufficient material strength or material defects, such as unrefined die steel, with a large number of smelting defects, will lead to an increase in mold processing losses.
Poor material performance, not wear-resistant, or convex and concave die, forging billet change forging process is not perfect, leaving hidden dangers of heat treatment, will also lead to accelerated loss of the die.
⒉ Design problems:
The mold design is unreasonable, the structure is complex, and the strength is insufficient, such as the slender punch is not designed to strengthen the device, and the discharge port is not smooth resulting in stacking, which will make the mold bear greater alternating load during the processing and aggravate the loss.
3. Processing problems:
Program errors, cutting tool wear, equipment aging and other processing problems are also the main reasons for mold processing losses. For example, the poor state of the discharge machining equipment or the insufficient working fluid medium may lead to unsatisfactory processing results and increase mold losses.
4. Process problems:
Problems such as unreasonable mold processing technology and non-standard operation will also lead to an increase in mold processing losses. For example, in the process of discharge machining, if the processing parameters are set improperly, such as discharge current, pulse time, etc., it may lead to a decrease in the surface quality of the mold and an increase in loss.
Discharge processing characteristics:
Although the discharge machining has the advantages of high precision and flexibility, in the processing process, due to the high temperature and high energy generated by the discharge, the surface material of the workpiece may melt and evaporate instantly, resulting in a certain loss to the mold.
Pictures operation and maintenance:
In the process of mold discharge machining, the skill level and maintenance of the operator will also affect the loss of the mold. For example, improper operation or maintenance of the equipment by the operator may lead to increased mold loss.
