Abstract
The invention is a CNC machine tool, namely a CNC lathe, that includes a horizontal main spindle. The unfinished parts to be machined are supplied to the machine tool horizontally to the working compartment by a handling device integrated into the CNC control, and are then supplied via the handling device to a chuck that is to the horizontal main spindle. The machine tool according to the invention is particularly well-suited for small machining runs.
Claims21
A CNC-controlled machine tool, comprising:
- a horizontally disposed main spindle with chuck, for receiving unprocessed workpieces to be processed;
- a first handling device disposed proximal to the main spindle and integrated in the CNC control;
- said first handling device being configured and arranged for picking up and delivering unprocessed workpieces to the chuck of the main spindle, rotatable about a spindle axis, and for removing processed workpieces;
- the chuck being located within a working space for processing workpieces;
- a first linear conveyor horizontally disposed parallel to the main spindle and outside of the working space;
- second handling device, driven by a motor and longitudinally reciprocatable along the first linear conveyor;
- a gripper connected to the second handling device;
- a second linear conveyor, driven by a motor, having an end;
- unprocessed workpieces being transportable on the second linear conveyor toward the second handling device;
- the second handling device with gripper being longitudinally reciprocatable along the first linear conveyor over the second linear conveyor;
- the second handling device sequentially removing unprocessed workpieces from the second linear conveyor to a working space for processing of the unprocessed workpieces;
- pressure plates, disposed divergently relative to each other, being located proximal to the end of the second linear conveyor;
- said pressure plates being configured and arranged to isolate an approaching unprocessed workpiece received from the second conveyor and to align the unprocessed workpiece in preparation for pick up by the gripper of the handling device and subsequent transport to the working space for processing;
- said pressure plates being actuatable in a longitudinal direction to assist in pressing up the unprocessed workpiece into a delivery position suitable for receipt by the gripper and subsequent transport by the handling device.
