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

  2020 / 07 / 01

  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

• What are the advantages of the side fixed handle

  2020 / 06 / 15

  Side fixed handle: it refers to the tool whose handle is flattened, which is usually used for quick drilling. The advantages are: high degree of clamping and concentricity, commonly used for connecting thread milling cutter, milling cutter, drill bit, large clamping force, suitable for machining with large cutting force. However, a bit of one size needs to be equipped with a chuck correspondingly, with many specifications. Secondly, it may cause the bit and the spindle are not concentric, which may cause damage to the bit during processing. The main characteristics of the side fixed boring cutter are: A. high precision B. large clamping force C. good rigidity D. strong directionality The side fixed taper handle is a first-class technology in the world, which can fit well with the spindle, prolong the service life of the cutter, repeatedly clamp, and has high precision. The surface hardness is high, which can reach 58 ° - 62 °. The product has high cost performance and stable quality. The side fixed shank is suitable for finishing, rough machining, plane machining, end face machining, groove, cut in machining, heavy cutting and other processing technologies. The shape of the side fixed shank is different due to the different clamping tools, and the corresponding locking screws are different. In use, the position of the side fixed screws must be confirmed. Only the plane position of the cutting tool can be locked.
