The numerically controlled lathe of drive head
Affiliated technical field
The utility model relates to a kind of numerically controlled lathe, particularly a kind of numerically controlled lathe of drive head.
Background technology
When numerically controlled lathe has helicla flute and circumferentially needs the tubular member of punching at the processing inwall, need workpiece is pulled down punching then from frock after processing inside and outside circle, efficient is low, and influences machining accuracy.
Summary of the invention
In order to overcome above adverse effect, the utility model provides a kind of numerically controlled lathe of drive head, and operation such as clamping workpiece of the numerically controlled lathe of this drive head just can be finished car, draws, brill has improved efficient, has improved machining accuracy.
A kind of numerically controlled lathe of drive head, it is characterized in that: lathe bed is oblique lathe bed structure, main shaft drives the chuck rotation, between main spindle box and the chuck dividing plate is arranged, the Z spindle motor drives workbench Z to moving, and X-axis motor-driven workbench X is equipped with many cover knife rests to moving on the workbench, workbench X is equipped with unit head to the lower end, around lathe bed the protection coaming plate is installed.
The numerically controlled lathe of described drive head is characterized in that: lathe bed is 45 ° or 60 ° of oblique lathe beds.
Adopt the beneficial effects of the utility model to be to have improved efficient, cost is low, the machining accuracy height.
