What are the fault diagnosis methods for the electrical system of NC vertical lathe?

What are the operating procedures for vertical lathes? The following will be explained in detail by the vertical car manufacturer.

1、 Operating procedures

（1） Conscientiously:

1. The rough surface of the workpiece shall not be directly placed on the worktable, but shall be supported by sizing block or screw top; It is forbidden to use the worktable for other operations, such as hammering to correct workpieces, welding workpieces, etc.

2. When aligning the workpiece, only jog the worktable to rotate and align at low speed, and do not align at high speed.

3. When starting and stopping the workbench, the starting and stopping handle of the workbench can only be pulled by hand, and pedaling is strictly prohibited.

4. When the worktable rotates, it is not allowed to do beam lifting and rapid movement of tool rest.

5. When moving the beam, loosen the clamping device first, and clamp it immediately after moving. After the beam is lowered each time, it shall be raised a little to eliminate the clearance between lead screws and nuts.

6. Gravity cutting is not allowed when the ram of vertical tool holder and side tool holder extends for a long time; When machining with vertical tool holder, especially for gravity cutting, the pillars shall be lowered to the position close to the work as far as possible.

2、 Structural features

1. Hydraulic transmission of main gearbox; The rotation speed of the worktable is selected manually through electro-hydraulic control;

2. The hydraulic system is equipped with a pressure maintaining device;

3. The beam clamping mechanism adopts spring clamping and hydraulic loosening;

4. Equipped with digital display device (special order required *);

5. Main gearbox and worktable spindle support and transmission automatic lubrication;

6. The tension of the main drive belt, the clearance of the main shaft bearing, the clearance of the vertical ram nut and the clamping force of the cross beam can be adjusted;
