-
The rough surface of the workpiece is not allowed to be directly placed on the work surface, and should be supported by a pad iron or screw top; it is strictly forbidden to use the work surface to perform other operations such as hammering to correct the work piece, welding the work piece, etc.
-
When aligning the workpiece, only jog the worktable to rotate at low speed for alignment, and high-speed alignment is not allowed.
-
When starting and stopping the workbench, the start and stop handle of the workbench can only be moved by hand, and pedaling is strictly prohibited.
-
When the worktable is rotating, it is not allowed to do the lifting of the beam and the rapid movement of the tool post.
-
When moving the beam, the clamping device must be released first, and the clamping device should be clamped immediately after the movement is completed. Each time the beam is lowered, it should rise a little to eliminate the gap between the lead screw and the nut.
-
Gravity cutting processing is not allowed when the ram of the hanging tool rest and side tool rest extends very long; when using the tool rest for processing, especially for gravity cutting, the beam should be lowered as close to the working position as possible superior.
-
When doing intermittent cutting, it is necessary to appropriately reduce the feed rate of the small CNC vertical lathe and the rotation speed of the worktable.
