    1, the line speed of the cutting disk is too large

    Problem: When the speed of the cutting disc shaft is too high, use a cutting disc with a larger diameter than the resin EN12413 cutting discs used in the past.
    Solution: Change the cutting disc shaft speed so that the cutting disc line speed is within the range of the highest line speed or use a small diameter cutting disc.

    2. The workpiece is stuck between the workpiece holder and the cutting disc

    Problem 1: The workpiece holder is poorly adjusted
    Solution: The distance between the workpiece holder and the cutting surface of the China cutting disc for metal is within 3 mm.

    Problem 2: Insert the workpiece between the workpiece holder and the cutting disc
    Solution: The workpiece is supported by the workpiece support and cannot be forced between the cutting disc and the workpiece holder.

    Problem 3: When side grinding is not performed for the workpiece holder for side grinding
    Solution: The flat cutting disc is forbidden for side grinding, the side grinding uses a bowl-shaped cutting disc, and the workpiece holder is correctly set up.

    3. 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

    Question 2: The shaft diameter of the cutting disc shaft is too small
    Solution: If there is a cutting disk of the same size as the shaft, use a cutting disk equivalent to this.

    Question 3: Wrong rough grinding or cutting disc usage error
    Solution: rely on the guidance of the skilled person or the cutting disc instruction manual for correct grinding

    4. When the imbalance of the cutting disc is too large

    Problem 1: The balance check of the cutting disc manufacturer is insufficient
    Solution: Recalibrate the balance on the balance frame

    Question 2: The cutting disc contains a part of the water
    Solution: the grinding surface is idling in the state of stopping the water injection.

    When using the side of the cutting disc, the use surface of the cutting disc is specified. It is strictly forbidden to use the cutting disc other than the side for side grinding.

    5, cutting disk strength is small

    When using the side of the cutting disc, the use surface of the cutting disc is specified. It is strictly forbidden to use the cutting disc other than the side for side grinding.

    6, the spindle diameter and the cutting disc aperture are not suitable

    Problem: The cutting disc aperture is too small compared to the standard size, and it is tough to fit on the spindle.
    Solution: There must be a proper gap between the cutting disc hole and the main shaft.

    7. Side grinding with an improper cutting disc

    When using a side grinding disc other than the cutting disc, it is necessary to use a cutting disc for side grinding (bowl cutting disc, etc.)

    8, the change of cutting quality

    Problem: When the cutting disk encounters a flood or fire, the resin bond, rubber bond cutting disk, etc. should undergo qualitative changes.
    Solution: Confirm the way the cutting disc enters. The correct storage should consider the date of manufacture of the cutting disc, and strictly check the inspection before use.

    9. In the case of breaking into three or more pieces in the radial direction

    Problem: The cutting disc uses excessive line speed; the cutting disc gasket is missing; the aluminum abrasive cutting disc hole is too small; the flange shape is not suitable and the screw is tightened too tightly
    Solution: Strictly observe the highest line speed specified by the type of cutting disc, carefully check the state of the installation of the cutting disc flange, and use it correctly.

    10. In the case of breaking into two pieces in the radial direction

    Problem 1: The cutting disk has cracks before use
    Solution: Strictly check before installation

    Question 2: Excessive use of the side of the cutting disc
    Solution: Do not use the side of the cutting disc

    11, irregular destruction

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