There are usually two methods for processing multi-line threads on CNC lathes: single-tool multi-line processing and multi-tool simultaneous processing.

1. Single tool multi-line processing:

Working principle: CNC lathe multi-line machining refers to using one tool to form multiple threads through multiple cuts.

step:

Tool preparation: Use a specially designed CNC lathe threading tool that has multiple threading cutters arranged along the tool axis.

Tool positioning: The CNC lathe CNC system accurately positions the tool on the workpiece by controlling the movement of the workbench and turret.

Multiple cutting with a single tool: The CNC lathe tool performs multiple feeds. Each feed cuts a small section of thread, and the entire multi-thread thread is processed through multiple cuts.

Advantages: CNC lathes simplify tool path planning and are suitable for relatively simple multi-thread processing.

2. Multi-tool simultaneous processing:

Working principle: Multi-tool simultaneous processing on CNC lathes refers to using multiple tools to process multiple threads on the workpiece at the same time.

step:

Tool preparation: Multiple tools of the CNC lathe are assembled on the turret, and each tool is responsible for processing a thread.

Tool positioning: The CNC lathe CNC system accurately positions multiple tools to their respective processing positions by controlling the movement of the turret and worktable.

Synchronous processing: Multiple cutting tools on a CNC lathe are cutting at the same time to complete the processing of multiple threads.

Advantages: CNC lathes have high processing efficiency and are suitable for occasions with high processing efficiency requirements, such as mass production.

The choice of which method to use usually depends on factors such as specific machining needs, the shape of the workpiece and the machining process. Single-tool multi-line processing is suitable for relatively simple multi-line thread processing, while multi-tool simultaneous processing is suitable for large-volume, complex-shaped multi-line thread processing.
