- CNC lathe parts processing is a high-precision and high-efficiency automated machine tool. Using CNC lathes can improve processing efficiency. The processing technology of CNC lathes is similar to that of ordinary lathes, but CNC lathes are disposable chucks that create more value. The emergence of CNC lathes has freed enterprises from their backward processing technology. To complete all the turning processes with continuous automatic machining, it is necessary to pay attention to the following points. So, let's learn about the complete set of CNC lathe parts processing techniques together!
The reasonable selection of cutting quantities for CNC lathe parts processing determines processing time, tool life, and processing quality. For efficient metal cutting, the material to be processed, the cutting tool, and the cutting conditions are three major factors. An economical and effective machining method inevitably selects a reasonable cutting condition.
The three elements of cutting conditions: a rise in the temperature of the tool tip can cause mechanical, chemical, and thermal wear. If the cutting speed is increased by 20%, the cutting speed, feed rate, and depth directly lead to tool damage. As the cutting speed increases, the tool life will be shortened by half.
The relationship between feed conditions and wear behind the tool occurs in a small range. The impact on the tool is less than the cutting speed. The cutting speed and feed rate are large, but the feed rate is large, the cutting temperature rises, and the rear wear is large. Cutting depth has no effect on the tool, but when cutting at a small cutting depth, the material to be cut will produce a hardened layer, which affects the life of the tool.
The user of CNC lathe parts processing must select the cutting speed to be used based on the processing material, hardness, cutting state, material type, feed rate, cutting depth, etc.
The selection of better processing conditions is based on these factors. Regular and stable wear is an ideal condition for reaching a lifetime.
However, in practical work, when determining processing conditions, it is necessary to conduct research based on the actual situation. Coolants can be used for difficult to process materials such as stainless steel and heat resistant alloys. The selection of tool life is related to tool wear, changes in the size to be processed, surface quality, cutting noise, and processing heat. You can also use a blade with high rigidity.
Reasonable selection of cutting tools for CNC lathe parts processing:
1. If it is rough turning, in order to meet the requirements of large size cutting tools and large feed rate, it is necessary to select tools with high strength and good durability.
When finishing a lathe, in order to ensure the processing accuracy requirements, it is necessary to select tools with high accuracy and good durability.
In order to shorten the replacement time and facilitate the use of knives, chuck knives and chuck knives should be used as much as possible.
Reasonable Selection of Fixture for CNC Lathe Parts Processing
Try to clamp the workpiece with a universal jig to avoid using a special jig;
In order to reduce positioning errors, it is necessary to comply with the positioning benchmark of the component. The processing route for determining the processing route refers to the movement path and direction of the tool relative to the part during the processing of a CNC machine tool.
CNC lathe parts processing determines the processing route
1. Requirements for ensuring machining accuracy and surface roughness;
2. Try to shorten the processing route and reduce the idle travel time of the tool. Generally, it is arranged to process excess allowance on an ordinary lathe, especially the allowance containing forged hard skin layer. When it is necessary to use a CNC lathe for machining, it is necessary to pay attention to the flexible arrangement of the program. Clamping mounting point Now, the connection between the hydraulic chuck and the hydraulic clamping cylinder is achieved through a pull rod. The clamping points of the hydraulic chuck are shown below. First, remove the nut of the hydraulic cylinder with a handler. The relationship between the processing process and the machining allowance is currently not widely used in CNC lathes. Remove the hose, pull it out from the rear end of the spindle, and remove the chuck fixing screw with a handler to remove the chuck.
