First, earnestly implement the "common metal-cutting grinder operation," .
Second, carefully following the General implementation of grinder
(A) install a new wheel must be:
1, double-check the new wheel, if cracks, scars strictly prohibited.
2, the new wheel should be after two serious static balance, that is, before the installation of the first, loaded with diamonds axis of the amendment and then removed once the balance.
3, the installation of a new wheel when the wheel flange and into the lining between 0.5 to 2 mm pad of paper. Flange screw should be tightened evenly, but do not compress the transition, so as not to Yahuai wheel.
4, installed a new wheel, in order to speed the work for less than 5 minutes of the air operation to confirm correct installation, operation before the normal work.
(B) before checking wheel and wheel cover should be good crack-free, the right to install, reliable fastening. No wheel covers are not allowed to switch on the machine.
(C) serious work to do:
1, the start of each wheel, hydraulic opening should stop cutting stop on the location of the handle to adjust the minimum speed on the location of wheel seat quickly into the position to handle on the back to avoid accidents.
2, the start of each wheel before start the pump or static supply lubrication oil system, the grinding( Grinding mill ) wheel spindle lubrication to be normal, the mercury switches from the top or static pressure to meet the design requirements value of the grinding wheel spindle after the float in order to start the wheel turning .
3, grinding the beginning, when the volume is smaller, slower speed to prevent wheel as a result of brittle Rupture cold, especially in winter when the temperature low to pay more attention to.
4, the rapid introduction of the workpiece grinding( Grinding mill ) wheel, the motor are not allowed to feed, not into the Big, prominent attention to the work site of edges and corners to prevent the collision.
5, grinding wheel spindle temperature exceeds 60 ° C when they have to stop when the temperature returned to normal after work.
6, are not allowed to use the grinding wheel as an ordinary wheel grinding machine, like East and West.
(D) the use of the machine tool coolant, the work should turn off the cooling pumps, wheel idle for a few minutes off the net and then stop coolant rotating wheel.
Third, carefully following the implementation of the relevant provisions of the special grinding machine.
(A) Grinder( Grinding mill ):
1, grinding up parts of the plate and supporting Plate support the installation location, should be able to meet the requirements of grinding work. Due to improper lead to the prevention of accidents.
2, grinding is strictly prohibited without bending or surface machining of the workpiece. Allowance should not work more than 0.3 mm.
3, the maximum speed when using the amendment to guide, should gear was torn off and destroyed to prevent the helical gear; when using the normal speed to amend round lead, helical gear should be torn off and the gear to be put up.
