Skills and Methods of Machining Step Parts on Surface Grinder

There are not many introduction materials on surface grinder grinding steps. It should be noted that the steps can be ground from two directions, and the basis for choosing which side to cut the steps from is efficiency. If the same part is changed in one direction, the grinding efficiency will be different. Which direction would you choose to start smartly?

1. Extra long workpiece grinding steps
When the grinding area of ​​the workpiece is relatively large, the heat generated during processing is large, and it is easy to deform, so you need to pay attention to the roughness, you need to choose the direction of cutting the steps, and it is best not to grind the sides and bottom at the same time when finishing, and use a coarse grinding wheel to lie down. Grind one surface, then stand up to grind the other surface, try to avoid grinding with the side of the grinding wheel, and finally replace the fine grinding wheel to clean the corners.

2. Grinding steps for small workpieces
Small workpieces often encounter steps of only 0.1mm or even 0.05mm. Grinding such steps can be processed at will for imprecise processing. For precision parts, the corners must be cleaned. Generally, the design will indicate the need for cleaning. The angle makes R less than 0.03mm, no matter how small the step is, it must be straight, even if there are only a few wires, the general material can be achieved by using 120K to clear the angle 3-5 times. It is more troublesome for materials with particularly high hardness, such as For materials such as DC53 and SKH-9, you need to change to a finer grinding wheel such as 360K to clean the corners, and the number of times needs to be increased accordingly. If you check the R size, the experienced master will take a long time to do it based on his feelings and experience. Friends can use projection to check, and they will know after a few projections.

3. Steps with R
This situation is also very common. It should be noted that when roughing, you need to leave the R position to open a step. When finishing, it is enough to repair the R directly.

4. Four-sided steps
For this type of workpiece, you need to pay attention to leaving a certain craft table on each side. Some places are called standing feet. Otherwise, there will be no support points when grinding the steps and finishing, and there is the possibility of deformation. The craft table does not need to be left too much, 0.7-2mm Yes, it is convenient to remove the craft table without deformation.
