Precautions when using high-precision double-end grinding machine

The operation of any machine tool product is more technical and dangerous. Therefore, before we operate the machine tool, we should have a brief understanding of the operation. We take a high-precision double-sided grinder as an example.

1. seriously implement the relevant provisions of the "metal cutting machine general operating procedures.

2. carefully implement the following general provisions for double-face grinding machines:

Installation of New Grinding Wheel for High Precision Double Face Grinding Machine:

1. Carefully check the new grinding wheel of the high-precision double-sided grinder. If there are cracks, it is strictly forbidden to use it.

2. The new grinding wheel to go through two serious static balance, before installation to the spindle on a diamond, and then remove the balance.

3. When installing a new grinding wheel, a paper pad of 0.5-2mm should be placed between the grinding wheel and the flange of the double-sided grinding machine. The flange screws should be tightened evenly, but not excessively pressed to avoid crushing the grinding wheel.

4. After the new grinding wheel of the double-sided grinder is installed, it can be idling for no less than 5 minutes at the working speed, and it can only work after confirming the correct installation and normal operation.

Before work, check whether the grinding wheel and grinding wheel cover of the high-precision double-sided grinder are intact and free of cracks, whether the installation is correct, and whether the fastening is reliable. The machine tool without the grinding wheel cover is not allowed to start.

3. serious work:

1. Before starting the grinding wheel each time, the hydraulic switch valve should be placed in the stop position, the adjustment handle should be placed in the low-speed position, and the grinding wheel rapid feed handle should be placed in the reverse position to avoid accidents.

  2.High-precision double-face grinding machine: Before starting the grinding wheel of the high-precision double-sided grinder, the lubrication pump or the oil pump of the hydrostatic oil supply system should be started first. After the grinding wheel spindle is lubricated normally, the mercury switch is jacked up or the hydrostatic pressure reaches the design value. After the grinding wheel spindle floats, the grinding wheel can be started to rotate.

3. At the beginning of grinding, the feed rate should be small and the cutting speed should be slow to prevent the grinding wheel from cold and brittle cracking, especially when the temperature is low in winter.

4. High-precision double-end grinding machine: When the grinding wheel quickly enters the workpiece, it is not allowed to power feed or large knife feed, pay attention to the protruding edges and corners of the workpiece to prevent collision.

  5.High-precision double-face grinding machine: When the temperature of the grinding wheel spindle exceeds 60, you need to stop working and wait until the temperature returns to normal before working.

It is not allowed to use the grinding wheel of a high-precision double-sided grinder as an ordinary grinder to grind things.

4. For double-sided grinding machine tools that use coolant, the cooling pump should be turned off after the work is over, and the grinding wheel should be idling for a few minutes before stopping the grinding wheel.

Tips

When more than one grinding wheel is installed on the grinding wheel chuck at the same time, it is allowed to separate the grinding wheels with a spacer. The diameter of the spacer and the size of its pressing surface with the grinding wheel need to be equal to the size of the grinding wheel chuck. Specially manufactured grinding wheels are allowed to be glued or stacked together for installation.

Well, thank you all for watching, and I'll see you next time.
