CNC lathe processing from LK

The machining process of CNC lathe is similar to that of ordinary lathe, but since the CNC lathe is a single clamping and continuous automatic machining to complete all turning operations, the following aspects should be noted.


1. Reasonable choice of cutting amount


For high-efficiency metal cutting, the material to be processed, the cutting tool, and the cutting conditions are three major factors. These determine processing time, tool life and process quality. A cost-effective processing method must be a reasonable choice of cutting conditions. The three elements of the cutting conditions: cutting speed, feed rate and depth of cut directly cause damage to the tool.


As the cutting speed increases, the tip temperature rises, causing mechanical, chemical, and thermal wear. Cutting speed is increased by 20% and tool life is reduced by 1/2. The feed conditions are related to the wear behind the tool in a very small range. However, the feed rate is large, the cutting temperature rises, and the rear wear is large. It has less effect on the tool than the cutting speed. Although the depth of cut has no effect on the cutting speed and the feed rate, in the case of small depth cutting, the hardened layer is generated by the material to be cut, which also affects the life of the tool.


The cutting speed to be used is selected according to the material to be processed, hardness, cutting state, material type, feed amount, depth of cut, and the like. The selection of the most suitable processing conditions is selected on the basis of these factors. Regular, stable wear and longevity are ideal conditions.


However, in actual operations, the choice of tool life is related to tool wear, machined dimensional changes, surface quality, cutting noise, machining heat, and so on. When determining the processing conditions, it is necessary to conduct research according to the actual situation. For difficult-to-machine materials such as stainless steel and heat-resistant alloys, coolant or a rigid blade can be used.


2. Reasonable choice of tools


(1) When roughing the car, it is necessary to select a tool with high strength and durability to meet the requirements of large back feed and large feed amount during roughing.

(2) When finishing the car, it is necessary to select tools with high precision and durability to ensure the processing accuracy.

(3) In order to reduce the tool change time and facilitate the tool setting, the machine clamp and the machine clamp blade should be used as much as possible.


3. Reasonable selection of fixtures


(1) Try to use universal clamps to clamp the workpiece and avoid using special fixtures;

(2) The part positioning reference coincides to reduce the positioning error.


4. Determine the processing route


The machining route is the trajectory and direction of the tool relative to the part during the index control machine tool processing.

(1) should ensure the processing accuracy and surface roughness requirements;

(2) The machining route should be shortened as much as possible to reduce the tool idle travel time.


5. Relationship between processing route and machining allowance


At present, under the condition that the numerical control lathe has not yet reached universal use, it is generally necessary to arrange excessive margin on the blank, especially the margin containing the forged and cast hard skin layer on the ordinary lathe. If you must use CNC lathes, you need to pay attention to the flexible arrangement of the program.


6. Fixture installation points


At present, the connection between the hydraulic chuck and the hydraulic clamping cylinder is realized by the tie rod. The hydraulic chuck clamping points are as follows: firstly, the nut on the hydraulic cylinder is removed by a wrench, the pull tube is removed, and the pull rod is taken out from the rear end of the main shaft, and then moved. Remove the chuck by removing the chuck retaining screw.
