CNC lathe processing auxiliary process knowledge

First, the composition of the CNC lathe processing process

The machining process of the CNC lathe is generally composed of one or several processes, and the process is divided into installation, station, step and feed, and the burrs are changed into qualified parts through various processes.

1. CNC lathe process

The process of a CNC lathe is the basic unit of the process, which refers to the part of a process (or a group of individuals) that is continuously completed at one work site (such as one device) for one (or several) workpieces. The main basis for the division process is that the workers, the workpiece, the work site (equipment) are unchanged, and whether the process of the process is continuous.

2. CNC lathe installation

In CNC lathe machining, the process of occupying a workpiece in a proper position and being clamped in a lathe or fixture is called clamping. In a process, it is sometimes necessary to perform multiple clamping of the workpiece. The part of the process that is completed after the workpiece has been clamped once is called installation.

3. CNC lathe station

The part of the process in which the workpiece of the CNC lathe is completed in one installation relative to the lathe or the tool for each machining position is called a station.

4. CNC lathe steps

The CNC lathe work step refers to the part of the process that is completed under the condition that the cutting speed and the feed amount are the same in the machining surface, the machining tool and the cutting amount. Any change in the three is another step.

5. Feeding of CNC lathes

CNC vertical thread lathe in one step, if the metal layer to be cut off by the machined surface is thick and needs to be cut several times, each cut is called a feed. If the thread is turned, multiple feeds are required under the thread step.

Second, the principle of CNC lathe process division

Process division can be divided into two different principles, namely, process concentration and process dispersion.

1. The principle of process concentration is to concentrate the processing of the workpiece in a few processes, and the processing content of each process is more. The process concentration is beneficial to the use of high-efficiency CNC lathes, which can reduce the number of lathes, the number of operators and the floor space. It can process more processes after one clamping, which not only ensures the mutual positional accuracy between the various machining surfaces, but also It reduces the amount of workpiece transport between processes and the auxiliary time for clamping workpieces. However, the investment in numerical control equipment, special equipment and process equipment is large, especially the adjustment of special equipment and process equipment is rather cumbersome, which is not conducive to the conversion.

2. The principle of process dispersion is to disperse the processing of the workpiece in a large number of processes. The processing content of each process is very small, the process dispersion makes the equipment and process equipment structure simple, the adjustment and maintenance are convenient, the operation is simple, the conversion is easy, and the selection is convenient. Reasonable cutting amount and reduced maneuver time. However, the process route with long process dispersion is long, and the required equipment and individuals are large, and the floor space is large.

The above is the decomposition of the CNC lathe processing process by the CNC lathe machine China manufacturer. The processing of a part consists of one or several processes, each consisting of installation, work station and work step, and the step is composed of feed.
