Selection of processing materials for computer gongs

CNC precision machining engineers summarize their experience in actual machining, mainly including the following situations:

1. The tubular material will bend and deform when it is cut open;
2. When the center of the part is hollowed by WEDM, the stress and deformation will occur;
3. POM deforms due to excessive cutting amount or high processing temperature;
4. Customized materials have not been properly and scientifically aged;
5. Other complex parts in the process of processing due to improper process settings resulting in subsequent processing deformation;

In order to avoid the deformation caused by the above conditions in the processing, thus affecting the precision of the workpiece, the technical personnel put forward the following countermeasures:

1. Appropriate and scientific aging treatment should be carried out for customized materials and hollow materials;
2. The stress effect of each process should be considered in the processing of complex structural parts,

Set up scientific and reasonable process flow;

3. In the processing of POM and PVC materials, it is necessary to consider the particularity of materials, set appropriate machining allowance, and adopt the principle of “a small number of times” for processing and measuring;
4. The processing of curved surface needs to design and make good fixture,

Balance the clamping force on the workpiece;

CNC machining center structure can be divided into two parts: host part and control part! The host part includes the body, headstock, worktable, base, column, beam, feed mechanism, tool magazine, tool changer, auxiliary system, etc

The structure of CNC machining center is as follows

CNC machining center structure can be divided into two parts: host part and control part!

The host part includes the body, headstock, worktable, base, column, beam, feed mechanism, tool magazine, tool changer, auxiliary system, etc. the control part includes hardware part and software part

The hardware part includes: computer digital control device (CNC), programmable logic controller (PLC) input and output equipment, spindle drive device, display device, etc.

Software part includes: system program and control program two parts!

The purpose of the automatic tool changer is to meet the processing requirements,

The tool installed on the spindle is automatically replaced. The automatic tool changer is a set of independent and complete parts.

The tool changing process of the automatic tool changing device consists of two parts: tool selection and tool change!

Tool selection means that the tool magazine will automatically move the tool to be used to the tool change position according to the tool selection instruction. Tool change is to take down the used tool on the spindle and install the selected tool on the spindle!
