The characteristics and operating procedures of CNC vertical lathe

The characteristics of CNC vertical lathes: CNC vertical lathes are large-scale mechanical equipment used to process large and heavy workpieces with large radial dimensions and relatively small axial dimensions, and complex shapes. It can also be used for threading, spherical turning, profiling, milling and grinding with the help of additional devices. Compared with the clamping of the workpiece on the inside of the clamping trim of the horizontal lathe.

On the vertical lathe, the spindle axis is arranged vertically, and the table top is in the horizontal plane, so the clamping and alignment of the workpiece are more convenient. This layout reduces the load on the main shaft and bearings, so the vertical lathe can maintain the working accuracy for a long time. Some operating procedures in CNC vertical lathe processing work: (1) Do it carefully in the work: 1. The rough surface of the workpiece is not allowed to be placed directly on the work table, and it should be supported by pad iron or screw top; it is strictly forbidden to use the work table for other purposes. Operations such as correcting workpieces with hammering, welding workpieces, etc.

2. When aligning the workpiece, the worktable can only be rotated at a low speed to align, and high-speed alignment is not allowed. 3. When starting and stopping the workbench, the handle of the workbench can only be turned by hand, and pedals are strictly prohibited. 4. When the worktable is rotating, it is not allowed to do the lifting of the beam and the rapid movement of the tool holder.

5. When moving the beam, the clamping device must be loosened first, and it should be clamped immediately after moving. After the beam is lowered each time, it should be raised a little to eliminate the gap between the screw and the nut. 6. It is not allowed to carry out gravity cutting when the ram of the straight tool holder and the side tool holder is extended for a long time; when using a vertical tool holder for processing, especially when doing gravity cutting, the beam should be lowered as close as possible to the work position.

7. When performing intermittent cutting, the amount of feed and the rotational speed of the worktable should be appropriately reduced. 8. When changing gears, the joystick must be pushed to the specified position. If the gears are not well meshed, they should be adjusted by micro-movement after work, and it is not allowed to forcibly move the worker's table"start stop"handle.

(2) After work, for machine tools with two vertical tool rests, the vertical tool rests should be stopped at both ends of the beam symmetrically; for machine tools with one vertical tool rest, the vertical tool rests should be parked in the middle of the beam; It should be moved to the Z lower end position of the column.
