Computer gong processing – product processing center

Product processing center refers to the processing center used to process products. There are large products and small products here. However, large machine tools are usually used to process molds, and there are a small number of products. Product processing center is the most widely used in the field of CNC machining center, because there are more products than molds. The products of many industries need to be processed by vertical machining center.

The main functions of the equipment are as follows:

  1. Milling, CNC milling machine generally should have three coordinate linkage function, which can carry out linear interpolation and arc interpolation, and automatically control the rotation of the milling cutter relative to the workpiece movement for milling.
  2. Drilling, reaming, reaming, countersinking, boring, etc. can be carried out by using fixed size hole processing tools, or milling cutter can be used to mill holes of different sizes;
  3. Tool compensation function, generally including tool radius compensation function and tool length compensation function.
  4. For the conversion of metric and English units, metric units (mm) and English units (inch) can be selected for programming according to the marking of drawings, so as to adapt to the specific situation of different enterprises.
  5. Absolute coordinate and incremental coordinate programming, the coordinate data in the program can be absolute coordinates or incremental coordinates, so that the data can be calculated or between 20%. The programming is more convenient.
  6. Adjustment of feed speed and spindle speed. The control panel of CNC milling machine is generally equipped with multiple switch of feed speed and spindle speed, which is used to adjust the actual feed speed and actual spindle speed at any time according to the processing status and program setting value during program execution, so as to achieve the best cutting effect. Generally, the feed speed adjustment range is between 0% ~ 150%, and the spindle speed adjustment range is 50% ~ 1.

This machining center is the commonly used equipment in CNC industry. The CNC equipment is composed of mechanical equipment and CNC system. It is an efficient automatic CNC machine tool used to process complex shaped workpieces. This equipment is originally developed from the CNC milling machine, but also in the later application process in the technical aspects of change. Moreover, this equipment is also a highly mechatronic product. After the workpiece is clamped, the CNC system can control the machine tool to automatically select according to different working procedures. In addition, it can automatically change the cutting tool and automatically change the spindle speed and feed rate. In addition, the equipment can also continuously complete drilling and boring Milling, reaming, tapping and other processes, which can greatly reduce the clamping time of the workpiece, as well as the auxiliary process time such as measurement and machine tool adjustment, and the more complex processing shape and higher accuracy requirements in application, as well as good experience in parts with frequent variety change Moreover, the current application equipment can gradually become the most important equipment in the mechanical processing industry,

The supporting parts of machining center mainly refer to machine bed, upright, beam, base and other large parts. Its function is to support parts, bear force and ensure their mutual position. Although the shape, geometric size and material of the support are various, they all satisfy the following points.

  1. The anti vibration property of the supporting part refers to its ability to resist forced vibration and self-excited vibration. Vibration will not only make the machine produce noise, but also affect the processing quality. Therefore, the support should have sufficient vibration resistance and have the required dynamic characteristics. The main factors affecting the vibration resistance of the support are: the stiffness of the support, the natural frequency of the support, the damping of the support, the support condition of the support and the material of the support, etc. in practice, the vibration resistance of the support is often improved by selecting the high damping material, adopting the high damping component, and improving the support condition of the support with the Linjia vibration damping pad.
  2. Stiffness requirements the stiffness of the supporting part refers to the ability of the support to resist deformation under the action of constant load and alternating load. The former is called static stiffness and the latter is dynamic stiffness. The static stiffness depends on the structural stiffness and contact stiffness of the supporting timber body. The dynamic stiffness is not only related to the static stiffness, but also to the damping and natural frequency of the supporting system. The most important factors affecting the stiffness of the support are the material and structure of the support. The stiffness of the support can be improved by using high rigid materials and increasing the elastic modulus of the material; the contact stiffness can be effectively improved by increasing the surface contact area, increasing the preload and improving the surface quality; It is an effective measure to improve the stiffness of supporting parts by adopting reasonable cross-section shape and configuring the stiffeners and stiffeners.
  3. The main factors affecting the thermal deformation of the supporting parts of machining center are: the structure of the support, the heating of the moving parts and the external heat source. The thermal deformation can be reduced by adopting the thermal symmetry structure, isolating the heat source, forced cooling and quick chip removal
