What should I pay attention to when using the polishing machine? How to use it correctly?

Polishing machines, also known as grinders, are often used for mechanical grinding, polishing and waxing. Is a kind of hardware power tools, I believe that a lot of understanding of the decoration operation, should know these tools, generally such tools are not used at will, then the use of polishing machine should pay attention to what? How to use the polishing machine correctly?

What should I pay attention to when using the polishing machine?

The polishing machine is composed of some basic components such as base, throwing plate, polishing fabric and polishing cover. The motor polishing machine is fixed on the base, and the cone sleeve used for the fixed throwing disc is also connected to the shaft of the motor by screws. The polishing fabric is fixed to the polishing disc by tightening, and the motor can be rotated by applying pressure after being powered on. The key to the operation of the polishing machine is to try to obtain a maximum polishing rate, so that the damage layer generated during polishing can be removed as soon as possible. It is also necessary to ensure that the polishing damage layer does not affect a tissue that is finally observed. The use of coarser abrasives can ensure a greater polishing rate to remove the polished damage layer, and the polishing damage layer is relatively deep. The latter uses a finer material, and the polishing damage layer will be relatively shallow. For the above problem, we can carry out polishing in two stages, the purpose of rough polishing is to remove the polished damage layer, this stage should have a large polishing rate, for the surface damage formed by rough polishing is a secondary consideration, but it should be as small as possible. The drawing machine is followed by fine throwing its purpose is to remove a surface damage generated and then reduce its damage to a minimum. When polishing the polishing machine, the sample grinding surface should be parallel to the polishing disc and evenly pressed on the polishing disc. Care should be taken to prevent the specimen from flying out or creating new wear marks because of too much pressure, and the specimen should also be rotated and moved back and forth along the radius of the turntable. In order not to wear too fast, it is necessary to constantly add a fine powder suspension to maintain a certain humidity of the polished fabric. We need to check the environment before using the polishing machine, the operator's hands and feet should be far away from the rotating polishing head, the operator can not step on the power cord or the power cord to wrap into the polishing head, and the power supply must be cut off when replacing or installing the light pad. If the operator has not received professional training or has not learned the safe operation procedures, the polishing machine is not operating normally do not use the high-speed polishing machine.

How to use the polishing machine correctly?

1. (Prelude to homework) :
1, first of all, clean the work site, clean the sanitation around the work, tidy up idle things, clean up the objects unrelated to the work, and discharge the work pieces to a proper position.
2. Test the polishing machine, start the polishing machine operation is abnormal, debug the fixed bolt firmness and looseness.
3, polishing machine operating tools have complete conditions.

Ii. (Normal operation) :
1, in the polishing machine operation process, must be in accordance with the requirements of the polishing machine to operate.
2, the operator shall not wear gloves during the normal operation of the polishing machine, which is the explicit regulation of the industry.
3, the operator must self-check the effect of processed items at any time, to see whether the processing of the workpiece has abnormal conditions, such as deformation, tip, impression and other adverse effects, it is necessary to maintain communication with the relevant staff at any time to prevent serious errors.
4, the work of the polishing machine is normal and abnormal, as an operator can feel or can hear the sound of the machine is abnormal, of course, to stop working immediately, eliminate the function of the fault in order to operate normally.
5, professional personnel professional operation, is beneficial to people and polishing machine.

Iii. (Follow-up work) :
1. After stopping work, it is also necessary to keep the polishing machine clean and clean up the production waste in time.
2, the operation tool is placed in the set position, the processing product workpiece is sorted out and discharged, and it is placed in the appropriate position.
3. Turn off the power and pull the plug cable.

The steps of using the polishing machine
1, start, turn on the "emergency stop" button;
2. Adjust the sink card position to properly clamp the sink, record the data of each card position, and take photos of the caliper position (Note: Align the water hole with the center of the turntable);
3. Number the program name and "reset" to the original position;
4, adjust the depth of the grinding wheel, pay attention to adjust the sensor lower limit position and screw position;
5, the existing data "data zero", press "debug stop", "debug start" light on, debugging begins, the steps are as follows:
① "grinding wheel", the grinding wheel forward to the appropriate position;
② "workpiece positive" rotates the workpiece at a certain Angle;
③ "after the grinding wheel", the grinding wheel is moved back to the appropriate position, so that the grinding wheel is in close contact with the arc of the sink.
6. After debugging the polishing machine, "monitor" the data to check whether there is abnormal data. If so, correct it;
7, after the completion of the correction, press "debug start", debug start light off, debugging end; Adjust to the "automatic" stop, then "reset", open the "automatic start", and test the sink;
8. Check the polishing effect, make corrections, and complete debugging.
