Grinding operations thus contribute greatly to the quality of the finished workpiece. However, problems can often occur during the grinding process. The biggest and most known problem is without doubt grinding burn, which is thermal damage to the rim zone of the part. Grinding burn occurs when too much heat is channelled into the part.

· Plunge grinding a form can be good, depending on specifics. It''s done quite a lot. The major first thing to think about is uneven wheel wear. For example, if you begin grinding a straight cylinder into a taper, the first part of the wheel to touch will get more wear than the last part.

For plunge grinding, ensure that wheel width is larger than work width. Use harder grade wheel. Incorrect wheel dressing: Adjust dressing tool so that the circumference of the wheel touches the circumference of the work: Faulty grinding operation: Check steady rest position. Feed table more smoothly. Do not allow wheel to separate from work on

If there is no deviation, the grinding rod is loaded, and then the grinding rod is close to the grinding wheel by dial indicator to check whether the grinding rod is bent ( usually the grinding rod allows the deviation to be within ).In addition to the above two points to ensure the improvement of the surface roughness of the grinding, and also pay attention to choose the right grinding

· Try grinding with your weak hand first then use your strong hand to match that grind. You may want to try slipping the belt over the edge a bit to round out the plunge somewhat. Also start at a higher grit until you get more practice. I used a worn out 80x or w/e Gator belt with a rounded off edge, it seemed to do a great job on plunges for me.
