Introduction of centerless grinding through adjustment method

Step 1. Select the correct insert. Starting with an outside diameter of 3-12, the principle is that T is less than the diameter of the workpiece and more than 1/2 the diameter. Then make sure the blade is parallel to the grinding wheel.

Step 2: Calculate Center Height

H (measured height) minus r (half the diameter of the workpiece) = center height. The center height should be greater than the standard for each type of machine. Basically, it should be about 1/4 of the workpiece. If this number is less than 1, we use 1.

Step 3.: Adjust the R.0W. rotation angle to determine the amount of grinding. If you want to grind 0.15 mm. The correct drawing will have a slight draft at the bottom. Then feed 0.15 mm and your workpiece will stop at the entry point. Where the entry point is depends on your adjustment of the feed and tilting angle.

Adjust the support tablets. If you are grinding 0.15mm, you must adjust the backward guide from the bottom. Then gradually adjust the front guide, feeding 0.02mm at a time, up to the entry point (determined by the dressing and tilting angles of the regulating wheel).

Step 4-1. Adjust the straightness of the rear support piece by using the point where the end touches lightly.

Step 4.2 Slowly feed a small amount at a time, depending on the amount of grinding. For example, if you are grinding 0.15mm (the grinding wheel must be 80% or above), you can test 0.02mm at a time. If it is 0.01mm for fine grinding, of course, it can only be 0.002mm each time to test, and use this distance to adjust the front support piece when it comes to the front.

Adjustment problem: If the head and tail dimensions are small. The armrest plate is shown in the figure below

Adjustment problem: If the head and tail dimensions are large. The armrest plate is shown in the picture below. To solve the problem, adjust one side of the head to be smaller to make sure the other side is normal. Then adjust the small size of the original head to the correct size.
