Methods of selecting, installing and changing tools magazine  for Precision cnc milling machine 850

The cutting tool is very important to the vertical machining center, and all kinds of process processing are completed by the tool magazine. Tool selection, tool installation and tool change are the most common processing procedures. Mastering these methods is very necessary for the daily operation of the machining center.

Vertical machining centers are currently very popular models, mainly used for processing small parts in industrial enterprises, teaching in colleges and universities, and processing daily handicrafts. Its biggest feature is high cost performance, good stability, strong reliability, and high machining accuracy. The vertical machining center can process some complex parts of flat, curved, and variable bevel angles. Machining centers also have shortcomings, that is, there are certain constraints on the dimensions and processing strokes of the processed parts. Generally, a tool magazine with about 20 tools is used for vertical machining centers (usually 24 tools).

There are also three ways to select a tool for the machining center:

1. Select the tools in sequence, install the tools in the tool holder according to the order in which the tools are used, and select them one by one according to the order, and then return to the original position after use.

2. Select the tool at will, encode the tool holder, put the corresponding tool into the prescribed tool holder, and use the address T to mark the tool holder code of the tool at the same time of programming.

3. Memorize the tool selection. In the memory of the machining center, record the tool number, storage location and tool seat number. When the tool storage address changes, the memory of the machining center will also change. In the tool magazine of a small machining center It is equipped with a position detection device, and the tool can be taken out and sent back at will.

Must-see precision Cnc Milling Machine 850 skills! Can reduce burrs without secondary processing

In the process of processing metal workpieces, machining centers often leave burrs on the parts. Deburring in order processing has become a fixed processing cost, which requires manpower, material resources and time. It is very necessary to reduce the generation of burrs in metal processing. In fact, there are many ways to reduce burrs, but the required cost and difficulty are different.

Fine screening of tool materials

The material of the tool is the reason that affects the cutting performance of the tool, especially in the high-speed cutting process of the machining center, the tool has to carry a large cutting force and is heated by high temperature to be oxidized, which will increase the wear of the tool. Once the tool is worn, the blade is damaged or dulled, it is easy to produce burrs, which are often difficult to remove. When designing the workpiece processing, the tool material must be selected according to the processing requirements and the properties of the workpiece material.

Tool angle quasi calculation

There are many categories of tool angles, mainly including rake angle, back angle, entering angle, back angle and so on. Properly increasing the rake angle can effectively reduce the deformation of cutting, which is helpful to reduce the generation of burrs. Increasing the relief angle can make the cutting edge sharper, thereby reducing the cutting edge squeezing the workpiece material. The entering angle and the back angle are factors that affect the residual area of the workpiece. Appropriately increasing the entering angle and reducing the back angle can also reduce the generation of burrs on the residual area.

Tool mechanism should be applicable

According to the processing requirements and processing conditions of the parts, various structural tools can be used to control the generation of burrs. For example, for burrs such as steel flanging, a very small arc can usually be poured, and it feels good to the touch. If a composite tool is used, the burr generated by the previous tool will be removed immediately after the tool. This can effectively control the generation of burrs and improve the processing quality without consuming too much cost, which is very suitable for our machining factories.

In short, although burrs cannot be completely avoided in the process of machining centers, it is necessary to seek an efficient, environmentally friendly, and low-cost deburring method. It is undoubtedly a good way to effectively avoid the generation of burrs by paying a little attention to the selection and use of tools.
