Cutting sheet safety requirements

1. The grinding machine must have the power required to grind under the maximum allowable load to ensure the normal operating speed of the spindle of the cutting blade.
2. The direction of rotation of the spindle thread of the cutting piece: the direction of the thread of the end of the aluminum flat cutting disc of the cutting piece for fastening the cutting piece or the cutting piece chuck must be opposite to the direction of rotation of the cutting piece when it is working. When the above requirements are not met, measures must be taken to prevent the 5 inch resin cutting disc for metal or the cutting blade chuck from loosening when the spindle of the cutting blade is rotated.
3. The length of the spindle thread of the cutting piece must be ensured that the entire compression nut is ******* in.
4. The threaded portion of the main shaft of the cutting blade must extend into the pressing surface of the compression nut, but must not exceed one-half the length of the inner diameter of the minimum thickness of the cutting piece allowed for the design.
5. The tensile strength of the spindle material of the cutting piece is not less than 650 N/mm 2 and the elongation is not less than 10%.
6. The diameter of the cutting disc chuck shall not be less than one third of the diameter of the mounted cutting piece. The diameter of the cutting disc chuck for cutting the cutting piece shall not be less than one quarter of the diameter of the mounted cutting piece.
7. Any type of cutting disc chuck, the diameter of the left and right parts and the radial width of the pressing surface must be equal.
8. The cutting disc chuck must be able to reliably transmit the driving force to the cutting piece.
9. The cutting disc chuck should have sufficient rigidity and the tensile strength is not less than 415 Newtons/mm^2. The pressing surface must remain flat and evenly contacted after tightening.
10. Grind all the rotating parts on the machine, such as: cutting blades, motors, pulleys and workpiece head holders, etc., must be installed with a protective cover. The protective cover should be firmly fixed and its joint strength should not be lower than the strength of the protective cover.
11. The cutting piece guard is generally composed of a circumferential member and two side members, and the cutting piece, the cutting piece chuck and the end portion of the cutting piece spindle should be covered. Its main performance is: when the cutting piece is damaged due to work, it can effectively cover the pieces of the fiber cutting disc Chinese supplier to ensure the safety of personnel.
12. The cutting blade shield can be round or square. The maximum opening angle is not allowed to exceed 90°, and the upper half of the cutting blade must be covered at all times. The area above the horizontal plane of the spindle center line of the cutting blade shall not exceed 65°.
