• A variety of tool holder selection skills, work easier

  Tool handle specification The 7:24 taper tool holder is used in most CNC tool handles, and the corresponding type of tension structure of the rivet is used to match with the spindle of the machine tool. There are various specifications of toolholder, commonly used are 40, 45 and 50. At present, iso7388-1983, GB 10944-1989, MAS 403-1982, ANSI / ASME b5.50-1985 are widely used in China. When selecting the tool holder, it should be considered that the specification of the tool holder is suitable for the machine tool spindle and manipulator. Specification and quantity of toolholder The integrated TSG tool system includes 20 kinds of toolholders, with hundreds of specifications. Users can select the types and specifications of toolholders according to the NC processing technology of typical parts, which can meet the processing requirements and avoid overstocking. Considering that there are a certain number of toolholders in pre adjustment or tool grinding while CNC machine tools are working, the number of toolholders is usually 2 ~ 3 times of the required ones. Matching of tool and handle Attention should be paid to the matching between the tool holder and the tool, especially when selecting the tapping tool holder, the size of the screw tap driving square head should be paid attention to. In addition, the use of single edge boring tool on CNC machine tools can avoid scratching the workpiece during tool withdrawal, but attention should be paid to the position direction of the tool tip relative to the keyway on the toolholder: some machine tools require the same orientation

• In CNC machine tools, what is the relationship between the toolholder and the toolholder?

  1. Reduce tool types: (1) The tool is composed of cutting part and clamping part. (2) There are dozens of standard forms for the installation of cutting tools. (3) If the tool is directly connected to the machine tool, different clamping parts should be made for the same cutting edge. This is obviously uneconomical and unrealistic. 2. Middle connection form -- toolholder: (1) The clamping part of the cutter is made into square, outer cylindrical, inner cylindrical and outer conical. (2) There are several ways to clamp one end of a machine tool. This is the handle. (3) Such a small number of tool connection forms and a small number of tool holder connection forms, there are a large number of combination forms, to meet a large number of different needs. 3. Connection of clamping tool: (1) The appearance of machine clip type non regrinding blade causes new problems in the connection between the blade and the cutter bar. (2) When the tool holder is directly installed on the machine, the cost will be increased. (3) Another intermediate is added, which is commonly called a knife bar. One end of the intermediate is installed with a clamping blade, and the other end is made into a traditional square, outer cylindrical, inner cylindrical and outer conical.

• Change of spring after unloading of spring collet

  What are the capabilities of the spring collet: The spring collet is made of alloy steel with good elasticity. After heat treatment, the outer cone of the head and the inner wall of the collet have high density to protect the strength and wear resistance. Each size of spring collet can clamp the workpiece in a very small size environment, so it is mostly used in self-propelled lathe and other efficient automatic machine tools. The combination of spring chucks is more real, rigid, able to bear large torque, eliminate the occurrence of loosening in rotation, use special performance of alloy steel energy, good durability, strong durability. Spring chucks are widely used as an elastic element in the machinery and construction industry, and the spring has relatively large elastic change in the absolute energy under load, so the mechanical The work or kinetic energy is converted into variable energy, and the change of spring disappears after unloading and returns to the original state. Spring chuck is a very convenient thing, but there are many problems that can hinder its use. Almost the friction between the clamp and the thing under the gas mine is an important problem that affects whether the clamp is clamped. In almost cases, the larger the friction, the tighter the clamp, and the smaller the friction, the opposite. First of all, it is the problem of his axis adjustment. Only when the action points of the big axis and the small axis are adjusted well, can the maximum clamping force be exerted. In view of the larger clamping force of the big axis and the smaller clamping force of the small axis, it is often important to adjust the length of the axis. However, there are too many small chucks in the East and West, and it is a general form th
