CNC knowledge and tool selection for CNC lathe processing

CNC lathe processing refers to a machine tool that uses CNC lathe to process parts. Exponential control CNC CNC lathe processing adopts NC machining language programming control, generally using G code. NC Corporation G code language tells NC lathe position coordinates of tool processing, and controls tool feed speed and spindle speed, as well as tool converter, cooling medium and other functions.

CNC lathe processing has great advantages over manual processing. For example, the parts produced by CNC lathe processing are highly accurate and repeatable; CNC lathe processing produces parts that are complex in shape and cannot be manually processed. CNC machining technology is now widely promoted, and most processing workshops have CNC machining capabilities. Typical CNC machining workshops usually adopt the processing methods: CNC milling machine, CNC lathe machining and CNC EDM wire cutting (EDM wire cutting).

CNC lathe has high machining accuracy, concentrated processing processes, and few parts clamping times, so higher requirements are put forward for the CNC tools used in CNC machine tools. The following will introduce to you what issues should be considered when processing CNC lathes?

1. Tool Requirements

When processing CNC lathes, the type, specifications and accuracy grade of the tool should meet the CNC machining requirements.

2. High precision

The tool must have high accuracy to meet the requirements of high precision in CNC lathe processing and automatic tool change.

3. Reliability

In order to ensure that there are no accidental tool damage and potential defects during the CNC lathe processing process, which will affect the smooth progress of processing, the combination of tool and tool accessories must have good reliability and adaptability.

4. Durability

Whether it is rough processing or finishing processing, the wear resistance of CNC lathe machining tools is higher than that of ordinary lathe machining tools, so as to minimize the number of tool replacement or grinding times and the number of tool adjustments, improve processing efficiency, and ensure processing quality. .

5. Good chip breaking and chip removal performance

In CNC lathe processing , chip breaking and chip removal cannot be processed manually in time like ordinary lathe processing. Chips are easily wrapped around tools and workpieces, easily damage the tool and scratch the processed surface of the workpiece, and may even cause injury to personnel and equipment accidents. , affects the safe operation of the machine tool, so the tool is required to have good chip breaking and chip removal performance.
