Processing method of computer gong

Computer gong processing is a complex processing by computer-controlled machine tools. The most complex part of the computer gong is the control system. The computer sends all kinds of instructions to control the three-axis servo motor of the machine. According to the established route, it cooperates with each other to process all kinds of complex processes and ensure high machining accuracy.

What are the common computer gong processing methods

1. Plane hole parts

Generally, point and line control computer gong machine tools (such as computer gong drilling machine) are used for processing. When selecting the process route, the two principles of processing accuracy and processing efficiency are mainly considered.

2. Rotating parts

Commonly used computer gong lathe or grinder processing.

a. Consider the processing efficiency: when processing on the lathe, usually the machining allowance is large, we must reasonably arrange the rough machining route to improve the processing efficiency. In actual programming, it is generally not suitable to use cycle instruction (otherwise, there are too many empty tools at work speed). A better way is to cut off the material as soon as possible with rough turning, and then finish turning.

b. Consider the strength of the tool tip: low strength tools are often used in computer gongs and lathes to process small grooves.

3. Plane contour parts

Commonly used computer gong milling machine processing. It should be noted that:

a. Cut in and cut out direction control: radial cut in, there are pits on the surface of the workpiece; horizontal cut in and cut out, the surface of the workpiece is smooth.

b. First approximation method selection: when machining irregular curve contour, the computer gong machine tool with only linear and circular interpolation function needs to use small linear segment or circular segment to approximate the machined contour (its error is called first approximation error). When approaching, the workpiece error should be within the qualified range, and the number of program segments should be less.

In the production and processing, there are two main forms: solid heat treatment and melt heat treatment. There is a certain difference between the two ways to make precision hardware processing parts. What’s more, they use different steel to make different workpieces.

CNC lathe is composed of bed, headstock, turret feed system, cooling and lubrication system and CNC system. Different from the ordinary lathe, the feed system of CNC lathe is qualitatively different from the ordinary lathe. It does not have the traditional tool box, slide box and change gear frame, but directly uses the servo motor or stepper motor to drive the slide and tool through the ball screw to realize the feed movement. The NC system consists of NC unit, input and output module and operation panel.

1. Solid solution strengthening: because the solute atoms enter into the gap or node of the solvent lattice, the lattice will be distorted and the hardness and strength of the solid solution will be increased. This phenomenon is called solid solution strengthening.
2. Compound: a new crystal solid structure with metallic properties is formed by the combination of alloy components.

Mechanical mixture: an alloy consisting of two crystal structures. Although it has two kinds of crystals, it is a component with independent mechanical properties.

1. Ferrite: interstitial solid solution of carbon in a-Fe (body centered cubic iron).
2. Austenite: interstitial solid solution of carbon in g-fe.
3. Cementite: stable compound (Fe3C) formed by carbon and iron.
4. Pearlite: a mechanical mixture of ferrite and cementite (F + Fe3C contains 0.8% carbon)
5. Ledeburite: a mechanical mixture of cementite and austenite (containing 4.3% carbon) Metal heat treatment is one of the important processes in mechanical manufacturing. Compared with other processes, heat treatment generally does not change the shape and overall chemical composition of the workpiece, but endows or improves the performance of the workpiece by changing the microstructure inside the workpiece or the chemical composition on the surface of the workpiece.
