Conventionally, surface grinding, which is carried out for the purpose of removing scratches from abrasive materials such as stainless steel materials, involves pressing a rotating grindstone (grinding head) against a stationary abrasive material at a constant pressure, and grinding along the length of the abrasive material. A known method is to move the grinding head by an appropriate amount in the width direction of the material to be abrasive at the end of each of the forward and backward steps.

However, in conventional grinding methods, the total length of the material to be abrasive is set as the grinding length using a counter, etc., and the grinding head starts grinding from one end of the material to be abrasive and stops when it reaches the other end. This process was performed by moving the abrasive material by an appropriate amount in the width direction and then turning it back, resulting in a time delay between when the stop signal and the retreat signal were sent and when the grinding machine started the specified operation. Or, if the stop and return position of the grinding head is displaced due to mechanical slippage of the grinding machine itself, and this accumulates during the entire reciprocating process, unground parts may appear on the side edges of the abrasive material 1 as shown in Fig. 2. Part 10a, 10
It remains as b. Manual work is required to grind these unground areas, which not only results in poor uniformity and reduced grinding accuracy, but also reduces product value.
There were drawbacks that adversely affected grinding work efficiency.

Similarly, when the grinding head passes the reference line and moves from the other side edge of the abrasive material to the return process, it coasts outward from the side edge of the abrasive material, stops, and then moves in the width direction of the abrasive material.

Grinding length detection means for detecting each L 2 is provided. The grinding machine 4 cuts each side end 2 of the abrasive material 1 in the length direction in response to a stop and retreat signal from the grinding length detection means.
After coasting outward from 0.30, it turns around. As this grinding length detection means, for example, the grinding length is set in a counter, the counter counts pulses from a pulse generator as the grinding machine 4 runs, and commands are given to stop and retreat the grinding machine 4.
