What Should Be Paid Attention To In The Machining Process Of Double Tool Post CNC Lathe

The double-tool holder CNC lathe uses multiple tools to cut at the same time, thereby shortening the processing time and improving the production efficiency. It is an efficient automatic processing equipment. However, the programming of a double-tool post type CNC lathe is complicated, difficult to program manually, and it takes a long time to adjust the machine tool. The following issues must be paid attention to in the machining process planning and CNC programming of the CNC column lathe:

1. Prevent geometric interference and process interference: Geometric interference is the collision between the tool and the machine tool, workpiece, fixture and between the left and right tool holders during the machining process. Machining interference is the machining parameter requirements of the cutting tools involved in the machining process. Conflicts, such as spindle speed and rotation direction.

2. Coordination of the left and right tool rest NC programs: the two tool rests of the double tool rest CNC lathe are usually controlled by two sets of CNC systems. One CNC is the main control system, and the NC programs of the two tool rests are compiled separately. Communication and coordination should be carried out between the CNC systems, which can be achieved through CNC program instructions.

3. Numerical control program optimization: According to the precision and processing requirements of the processed parts, the processing tasks and processing sequence of the left and right tool holders are reasonably arranged without interference to shorten the service life of the single tool holder.
