Due to the high speed of pottery wheel, grinding wheel and more brittle, damaged and may occasionally result in serious consequences, therefore, whether the wheel is installed properly reasonable, safe and reliable, it is very important. Wheel of installation must be carried out carefully to ensure production safety grinding.
Ceramic wheel installation should pay attention to the following safety technology issues.
① aperture wheel should be freely attached to the concrete cutting wheels spindle or wheel chucks, and remain in compliance with the clearance aperture crude refining on the technical requirements.
Wheel pore size is too large, allowing the use of the liner shrinkage. Bush width smaller than the width of the wheel, but not less than 1/2 the thickness. Wheel chuck diameter of not less than 1/3 the diameter of the wheel, the wheel in order to ensure there is enough power and torque.
Wheel chuck have sufficient rigidity, after pressing the sides to maintain contact with the wheel flat and uniform, must be pressed between the pad surface with a flexible gasket (asbestos rubber sheet) and a thickness of 1 ~ 2mm, a diameter greater than card disc diameter 2mm appropriate. To ensure that the contact surface between energy compaction, compaction, should be kept clean and free of attachments.
When ② installation woodworking saw blade, should pay attention to controlling the compression nut or screw tightness, it is necessary to ensure when the grinding wheel does not slip, but also to prevent excessive pressure, resulting in wheel damage, therefore, it is best to use a torque wrench. If multiple time compression screw shall diagonal order, gradually tightening; wheel and chuck the total weight exceeds 16kg, it should be mounted on a grinder lifting methods and collision avoidance; install the new wheel to check to make sure safe only after the test, all the normal sounds and operation, etc., that can be put into production.
