Matters wheel in place before the inspection and installation should be noted

First, install the front wheel in place before the check in place, with the visual inspection method or using sound test method to check the confirmed cases of damage or injury to the existence of the grinding wheel to be installed, as well as checking grinder (or machine) and Wheel of speed between matches. Check the wheel in place prior to note the following:
A first wheel by visual inspection of  abrasive fibre disc the inspection. Visual inspection method: All wheel before use must be visually inspected and, if damaged, do not use. 2, if necessary, use sound test method for further confirmation. Sound Inspection Act (also known as the percussion test): vitrified grinding wheel before use advanced sound check. If the wheel five crack, then crackled, and vice versa issued or hoarse voice muffled. 3, is not allowed to have cracked or damaged wheel onto the axle in place, it will not only dangerous, but will also cause the appearance of precision grinding workpiece great deviation. 4, is not allowed due to covet fast pursuit of speed, wheel over wheel when using the defined maximum safe use of speed. 5, the use of the process, we should always proofread machine speed grinder or whether those indicated under the wheel speed or equal to the maximum safe use. Found nothing wrong to make timely adjustments. Second, install the  Grinding wheel china correct wheel when the wheel is installed in place is extremely important step for safe and effective use of the wheel, the wheel must be in place to ensure the implementation of the staff has considerable practical professional level.
A wheel spindle must straight, smooth, clean, non-destructive; spindle dimensions must allow tolerance range.
2, is not allowed to force the wheel mounted on the spindle of the grinding wheel, or any change in the aperture. If the spindle does not match the aperture wheel, please choose another size matching wheel. 3, the wheel must be free or attached to the spindle flange. 4, flange, chuck clamping surfaces must be smooth, clean, and the outside diameter of at least not less than one third of the wheel diameter. 5, flange  zirconia flap disc flatness require periodic measurements. Right flange flatness should be within 0.01mm of, if there is flatness tolerance, you need to perform maintenance on the flange. 6, does not allow the use of clean, unbalanced, with a burr or a different size, different flange concave pattern. 7, for multi-point fastening flange, be careful not to tighten the screws too tight.
8, for multi-point fastening flanges should be based machine manufacturer recommended torque flange size fastened firmly and evenly on the wheel. Note that when installing screws and nuts tightness, and not pressing enough to drive wheel slippage is appropriate. When multiple screws should be tightened diagonally order, fractional gradually tightened, conditions should be used to force wrench.
