Grinding is widely used and is one of the main methods for precision machining of machine parts. However, due to the high speed of the grinding wheel of the grinding machine, the grinding wheel is relatively hard, brittle, and cannot withstand heavy impacts. Therefore, the safety technical work of grinding processing is particularly important, and reliable safety protection devices must be taken, and the operation should be concentrated to ensure that nothing goes wrong.

In addition, the fine sand and metal chips splashed on the workpiece of the grinding wheel during grinding will hurt the eyes of workers, and workers should take appropriate protective measures if they inhale a large amount of such dust. The following safety technical issues should be paid attention to during grinding processing.

Before starting, the machine should be carefully and comprehensively inspected, including the inspection of the control mechanism, electrical equipment and clamps such as magnetic chucks. After inspection, it will be lubricated, and after lubrication, test run will be carried out to confirm that everything is good before it can be used.

When loading the workpiece, it is necessary to pay attention to the clamping and clamping, because the loosening of the workpiece during the grinding process will cause the workpiece to fly out and hurt people or break the grinding wheel. When starting to work, the manual adjustment method should be applied to make the grinding wheel slow down and close to the workpiece, and the starting feed should be small, and the force should not be too strong to prevent collision with the grinding wheel. When it is necessary to control the reciprocating motion of the workbench with a baffle, it is necessary to accurately adjust the reciprocating motion according to the grinding length of the workpiece, and tighten the baffle iron.

When replacing the grinding wheel, it is necessary to first carry out a visual inspection to see if there is any external injury, and then hit it with a wooden hammer or wooden rod to ensure that the sound is crisp and there are no cracks. When installing the grinding wheel, it must be assembled according to the specified methods and requirements, and the static balance is installed after debugging, and the test run can be used only after everything is normal.

Workers should wear protective glasses at work, and trim the grinding wheel in a balanced manner to prevent impact. Measuring the workpiece, adjusting or wiping the machine is carried out after the machine has been stopped. When using magnetic suction cups, the disc surface and the workpiece should be cleaned, close to each other, and sucked firmly, and if necessary, a baffle can be added to prevent the workpiece from shifting or flying out.

It is necessary to pay attention to the installation of the grinding wheel guard or the machine tool baffle, and the standing position should be sideways to the front of the high-speed rotating grinding wheel.

1.Before starting (instrument), it is necessary to check whether the device of the workpiece is correct, whether the fastening is reliable, and whether the magnetic chuck is out of order, otherwise, it is not allowed to drive.

2.When starting, the manual adjustment method should be used to leave a proper gap between the grinding wheel and the workpiece, and the initial feed should be small to prevent the grinding wheel from cracking.

3.Measuring the workpiece or adjusting the machine and cleaning work should be stopped before proceeding.

4.In order to prevent debris from injuring people when the grinding wheel is damaged, the grinding machine must be equipped with a protective cover, and it is forbidden to grind with a grinding wheel without a protective cover.

1. Lubricate all parts of the machine tool before starting the grinder, check that the mechanical transmission is normal, the switch button is sensitive and reliable, and the grinding wheel is intact and undamaged.

2. Start the grinding wheel to the normal processing speed in a jog mode and idle for five minutes.

3. Attention should be paid to the installation of grinding wheels; 1.Before installation, check the complete appearance of the grinding wheel, and tap the grinding wheel to hear a crisp sound to ensure that the grinding wheel is intact and undamaged. 2.

The flange clamping grinding wheel should be padded with an asbestos pad, and the first balance should be carried out after clamping, and the new grinding wheel should be idled for five minutes.

Fourth, the amount of grinding is reasonably selected, and overload grinding is strictly prohibited.

5. Before grinding, check whether the workpiece is firmly sucked or clamped firmly, and when clamping the workpiece with high workpiece and small bottom area, it should be clamped with a block or a special fixture to prevent failure.

6. No one is allowed to stand in front of the rotation of the grinding wheel when the machine is started, so as to prevent the grinding wheel from breaking and flying out or the workpiece from flying.

7. At the end of the work, the machine tool is wiped clean, the power supply is cut off, the other parts are placed neatly, and the work site is kept clean.

8. If the fault is found, cooperate with the maintenance personnel to overhaul it, and keep the scene in case of an accident, report it immediately and deal with it in time.

Safe operating procedures for grinding machines.

1. Before work, machinery, electrical appliances, protective devices, dust collection devices, work card measuring tools, etc. should be inspected, and they must be in complete and good condition.

2. After manually inspecting each part, run the empty car, check the longitudinal reciprocating movement of the grinding head, and confirm that it is normal, and then carry out the work.

3. Before work, according to the grinding length of the workpiece, manually adjust the position of the reversing baffle and tighten it.

4. When the machine tool is working, the pressure of the hydraulic system should not exceed the specified value range. The oil temperature shall not exceed 50, and when there is air in the cylinder, the grinding head should be walked back and forth several times with the maximum stroke to exhaust the air.

5. The machine tool does not have an automatic and manual interlock mechanism for longitudinal movement, and the handle must be pulled out when the hydraulic automatic reciprocating motion is used.

6. Check the fixture, the fastening of the workpiece, the balance fastening of the grinding wheel and the tightness of the belt during the work. The grinding wheel should be dull and should be trimmed in time.

The machine tool is a dangerous and valuable production tool, so it must be used correctly and maintained after work when using the machine tool. Surface grinders are a type of machine tools, and naturally the same.

The following is a brief introduction to the safe operation and maintenance methods of surface grinders

Operation of surface grinders:

1. Before using the machine, check whether the left and right automatic control levers of the machine are in place, and check whether the grinding wheel is firm;

2. When the left and right automatic control levers are started, pay attention to whether there are people on the left and right;

3. Use the special dresser for surface grinder to dress the grinding wheel;

4. Before the workpiece is processed, the burrs on the workpiece should be removed, and the workpiece and the working platform must be wiped dry;

5. When the grinding wheel does not stop rotating, it is strictly forbidden to wipe the working platform under the grinding wheel and take the workpiece;

6. Before processing, check whether the disk is flat;

7. After the workpiece is placed, pay attention to whether it has been magnetically absorbed;

8. The magnetically absorbing and movable workpiece should be fixed with a file block;
