There are many types of bunnings angle grinder discs, and the shapes and sizes are also different. According to the abrasives of the bunnings angle grinder discs, the binder material and the manufacturing process, each bunnings angle grinder discs has a certain application range. Improper selection will directly affect machining accuracy, surface roughness and production efficiency. Therefore, the grinding process must be selected according to the specific conditions of the corresponding bunnings angle grinder discs. How to choose the right bunnings angle grinder discs? For the bunnings angle grinder discs used in the abstract, let everyone clearly choose the bunnings angle grinder discs.
The inner hole of the bunnings angle grinder discs and the outer circle of the bunnings angle grinder discs or the flange should not be too tight. Otherwise, the heat will expand when grinding. The bunnings angle grinder discs is easy to expand and should not be too loose. Otherwise, the bunnings angle grinder discs is easily eccentric, loses balance and is vibrating. Generally, the matching clearance is 0.1~0.8mm, and the high-speed bunnings angle grinder discs gap is smaller. When using a flange pinch roller, the diameters of the two flanges should be equal and the outer diameter should not be less than 1/3 of the diameter of the wheel. Apply thick cardboard or oil-resistant rubber between the flange and the bunnings angle grinder discs surface, such as the lining plate, so that the pressure is evenly distributed. The tightening force of the nut should not be too large, otherwise the bunnings angle grinder discs will be broken. Please note that the rotation of the fastening threads should be opposite to the rotation of the bunnings angle grinder discs.
The general diameter of a bunnings angle grinder discs larger than 125 mm should be balanced so that the center of gravity of the bunnings angle grinder discs coincides with its axis of rotation.
Uneven bunnings angle grinder discs produce vibrations at high speeds, the quality of the color rings and the accuracy of the machine, severe damage and broken bunnings angle grinder discs. The main cause of the imbalance is uneven wheel density, asymmetrical geometry and eccentric mounting. Therefore, balance should be done before the wheel is installed. The balance of the wheel is both static and dynamic. In one case, only static balancing is required, but dynamic balancing must be performed when cutting high speed mushrooms (speeds greater than 50 m / s) and high structural grinding.
If the wheel is unbalanced, the heavier part is always below. Then balance the position of the balancing block. The balance sanding discs velcro should be inspected before it is mounted on the machine tool spindle, and the broken bunnings angle grinder discs is absolutely forbidden. The between the bunnings angle grinder discs and the flange should be 0. The elastic pad of the 5-1 book: the two flanges must be equal in diameter and usually half the diameter of the bunnings angle grinder discs.
The method of balancing the bunnings angle grinder discs: loading some balance blocks in the annular groove of the bunnings angle grinder discs flange, and adjusting the position of the balancing block so that the center of gravity of the bunnings angle grinder discs coincides with its rotating axis.
