What is the grinding method in the mold processing operation of the original state of round parts?

 ⑴ Longitudinal grinding method:

During grinding, the table is used for longitudinal reciprocating feed, the grinding wheel is used for periodic transverse feed, and the grinding allowance of the workpiece is gradually worn in multiple reciprocating strokes

to…



Features: The grinding efficiency is relatively low, but the surface quality is good and the roughness is low.

(2) Cutting grinding method (transverse grinding method) :

When the width of the grinding wheel is greater than the length of the grinding surface, the workpiece does not move longitudinally during the grinding process, but the grinding wheel is continuously transverse to the workpiece

Feed in.

Features: high grinding efficiency, but the grinding force is large, the grinding temperature is high, and sufficient coolant must be supplied when grinding.

(3) Composite grinding method:

This is a comprehensive application of longitudinal grinding and transverse grinding. First, the workpiece is segmented rough grinding by the transverse grinding method, each section leaves a fine grinding allowance, and the adjacent two sections have a certain amount

Overlap. Then use the longitudinal grinding method for fine grinding.

Features: Both horizontal grinding method of high efficiency and vertical grinding method of good quality advantages.

⑷ Deep grinding method:

This method has high productivity, but the grinding wheel dressing is complicated, and the structure of the workpiece must ensure that the grinding wheel has sufficient cutting and cutting length.

Features: When grinding, the grinding wheel is trimmed into a cone or step shape at one end, and the circular feed speed of the workpiece and the longitudinal feed speed are very slow at one time

Full grinding allowance is eliminated in longitudinal feed.

⑸ Hand grinding:

It is pressed on sandpaper with bamboo or hardwood that is softer than the grinding part material. The grinding fluid can be kerosene or light oil.

The grit of the sandpaper is gradually changed from coarse to fine until the desired surface finish is achieved.

(6) Grinding with abrasive particles:

For small parts or characters and patterns that cannot be ground with whitetstone and sandpaper, abrasive particles (such as alumina and silicon carbide) can be glued to the grinding rod with oil

, emery, etc.) for grinding.

⑺ Grinding with a grinding paste:

Use bamboo sticks and wooden sticks as grinding tools to grind with grinding paste. The paste should be diluted with kerosene or gasoline when used.
