CNC lathes or lathes are usually used to produce turning parts, forming different materials into the desired shape. There are also many types of workpiece materials, so it is particularly important to choose a suitable CNC lathe for workpiece processing.

 

As the leading mini cnc lathe supplier, the following will introduce the selection principle and three elements of the cnc lathe.

Selection principle

 

The basic principle of determining the three elements: first, determine the anti grasping amount according to the cutting requirements, then look up the table to obtain the feed rate and then look up the table to calculate the main cutting speed formula. Reasonable cutting quantity selection is related to many factors, such as lathe, tool, workpiece, and process.

 

The method of reasonable selection of processing dose is as follows:

 

  1. During rough machining, high production efficiency should be ensured. Therefore, a large reverse grasping amount, large feed rate, and medium or low cutting speed U should be selected.

 

  1. When finishing, it is mainly to ensure the requirements of the size and surface accuracy of the parts. Therefore, a smaller reverse cutting amount, smaller feed rate, and higher cutting speed are selected.

 

  1. During rough machining, it is usually necessary to give full play to the potential of the machine tool and the cutting ability of the tool. During semi-finishing and finishing, the CNC lathe factory should focus on how to ensure the machining quality and improve productivity to a great extent on this basis. When selecting the cutting amount, the CNC lathe factory shall ensure that the tool can complete the parts or ensure that the durability of the tool is not less than one shift and not less than half of the working time of the shift.

 

The specific value of cnc lathe factory shall be selected according to the specifications in the machine tool manual, the durability of the tools, and practical experience.

 

Selection of reverse grab amount

 

The selection of reverse grasping amount shall be determined according to the stiffness of the machine tool, fixture, workpiece, and the power of the machine tool. If the processing system allows, please select as many rear knives as possible.

 

In addition to the allowance left for future machining, the remaining rough machining allowance shall be reduced as much as possible at one time to greatly reduce the number of passes. Generally, on medium power machine tools, the post-cutting amount of rough machining is 8 to 10 mm (one side). The semi-finish machining of a small cnc lathe is 0.5 to 5 mm, and the precision machining range is 0.2 to 1.5 mm.

 

Determination of feed speed

 

When the quality of the workpiece can be guaranteed, a higher feed speed can be selected to improve productivity. When cutting, deep hole machining, or finishing in cnc lathe factory, it is recommended to choose a lower feed speed. The feed speed shall be compatible with the spindle speed and the number of rear knives. During rough machining, the selection of feed is limited by cutting force.
