1. Crack caused by cracking of the cutting piece

Problem 1: When the cutting hole is small or the shaft is strong, it is hard to load.
Solution: the cutting hole and the shaft should be able to be smoothly loaded, but not rigidly loaded.
Problem 2: The flange support is uneven (the flange is bent; the lead filling layer is convex; the flange is burred; the cutting surface is not flat)
Solution: The left and right sides of the aluminum abrasive cutting disc flange should be finished to the specified correct and smooth size, and the flat part of the cutting piece should be processed accurately, and the lead filling layer can not be convexly protruded.
Question 3: The tightening force of the nut is too large
Solution: If the tightening nut of the flange is too strong, the flange will be twisted, so that the local force of the cutting piece is large, so it should be tightly tightened.
2, the line speed of the cutting piece is too large
Problem: When the rotational speed of the cutting blade shaft is too high, when using a cutting piece having a larger diameter than the 14 inches cutting disc used in the past
Solution: Change the speed of the cutting blade shaft so that the cutting wire speed is within the range of the highest line speed or use a small diameter cutting piece.
3. When the imbalance of the cutting piece is too large

Problem 1: The balance check of the cutting sheet manufacturer is insufficient
Solution: Recalibrate the balance on the balance frame
Question 2: The cutting piece contains a part of water
Solution: the grinding surface is idling in the state of stopping the water injection.
4, the cutting piece strength is small

When using the side of the cutting piece, the use surface of the cutting piece is specified. It is strictly forbidden to use the cutting piece other than the side to perform the side.
5. Insufficient inspection of the grinding machine or improper machine tool

Problem 1: The bearing is loose, the spindle is bent, and the precision of the grinding machine is significantly reduced.
Solution: Check and repair the grinding machine to improve its accuracy
Problem 2: The shaft diameter of the cutting piece shaft is too small
Solution: If there is a cutting piece of the same size as the shaft, use a cutting piece equivalent to this.
Question 3: Wrong rough grinding or cutting piece use error
Solution: rely on the guidance of the skilled person or the cutting blade instruction manual for correct grinding operation
6. Side grinding with unsuitable cutting blades

When using a side cutting blade other than the cutting piece, it is necessary to use a cutting piece for side grinding (bowl cutting piece, etc.)
7, cutting sheet changes

Problem: When the cutting piece encounters a flood or fire, the resin bond and the rubber bond cutting piece should undergo qualitative changes.
Solution: Confirm the way the cutting disc for stainless steel enters. The correct storage should take into account the manufacturing date and time of the cutting piece, and strictly check the inspection before use.
8, irregular destruction

Problem: The quality of the cutting piece is not good; the cutting piece is pressed by the heavy object; the unreasonable mounting of the cutting piece
Solution: Ensure the quality of the product, enter the inspection to study the condition in detail, and strictly prohibit the installation of heavy objects on the cutting piece to be smooth and smooth.
