M250A Internal Grinding Machine Tool

 Adjustment and use of machine tools

Before operating machine tools, operators must have a detailed understanding of the structure of each part of machine tools, so that we can correctly adjust and use, and correctly maintain and maintain machine tools. According to figure 8-1 lubrication shown in full figure oil before driving, adjust and operate the machine according to the following principles.

(1) pre operation adjustment (see Figure 7-1)

1, the adjustment of each bump and press board on the workbench:

(1) 16 block in the table should be left when the left wheel surface projecting workpiece of 1/3 wheel width and the reversing handle 25 to the middle position of collision.

(2) block in 14 to be the table right, right end wheel width of the grinding wheel and the workpiece from the 1/3 to the middle position between the reversing handle 25.

(3) block 12 should be in the right table, grinding wheel dresser diamond tip exit 2-3 mm and the reversing handle 25 to the middle position of collision.

(4) block 13 should be in the state of the left wheel dresser, exit 2-3 mm diamond tip and the reversing handle 25 to the middle position of collision.

(5) when grinding, 21 screws should be 3~5 mm away from the long right side of the front part of the bed when it is on the right side of the table.

(6) according to the size of the grinding hole and the size of the grinding wheel, the relative position of the center line between the workpiece spindle and the grinding shaft is adjusted, so that the wheel and the end face of the workpiece can be avoided after driving, resulting in accidents of the body and equipment.

In the above adjustment, we should take into account the difference between the worktable's slow and slow speed. After adjusting, we should trim it when moving at work speed, especially when grinding through holes and stepped holes.
