• How to maintain the numerical control tool holder?

  2019 / 12 / 04

  Tool holder is an important connecting accessory of machine tool and cutting tool. The connecting part of the machine tool and the handle, the handle and the cutting tool are mostly used for metal processing. They should not be stained with metal powder and impurities, and should be kept clean at all times. To avoid damage to the handle. In order to ensure the accuracy, the important mating surface cannot be treated after grinding. Maintenance method of CNC tool shank: 1. Reduce the contact between the sweat on the hand and the handle of the knife, try not to grasp the knife with bare hands, and apply anti rust oil in time after grasping the knife with bare hands. When the handle is installed and disassembled by hand, form a good habit of applying antirust oil after the handle is removed and before installation; 2. Check the concentration of coolant regularly to prevent the concentration of coolant from decreasing, bacteria from multiplying and breeding in large numbers, and accelerate the corrosion of blade handle. The antirust aging of the coolant is different. Choose the appropriate antirust aging coolant; 3. It is necessary to clean and rust proof the handle of the knife before the holidays. For the handle that is not used for a long time, be sure to apply antirust oil for preservation, and reapply antirust oil regularly. The service life of the handle is usually 5-8 years. Selecting the handle with excellent performance and stable quality can effectively save production cost. The routine maintenance of CNC tool holder can effectively increase the service life of tool hol

• Spring collet is widely used

  Production skills of spring collet: first add the collet into the pressure cap on the way, gently run the circlip, and when the eccentric layout of the pressure cap is concave into the groove of the circlip, evenly and forcefully promote the circlip along the direction of the arrow, the cone can be broken. The ER chuck only needs to be turned to the sliding sleeve to change the drilling and tapping sleeve rapidly. When drilling, the Morse sleeve can be found automatically; when tapping, the torque reserve load can slip smoothly, which inevitably prevents the tap from breaking. In addition, when changing tools outside the boundary, use a wrench to loosen the pressing cap to take out the collet and the tool, remove the tool, force the circlip along the direction of the arrow, exit it, and then replace the circlip with another hole diameter as required. The adjustability of the spring collet is usually selected according to the law of bolt fastening and pin position. When the collet is adjusted and arranged, the length of a circuit can be easily polished. Spring chuck has a lot of clamping force ratio, a wide range of clamping plane, and a high reliability at the same time, so it has been widely used in some industries, such as the application in machine tool industry. For ER chuck, it has different types, and different types of chuck are applied in different levels. It can have not low reliability, can quickly position the parts in a certain direction, which plays an important role for the smooth production of the manual, and also improves the production efficiency of the manual. The spring chuck should pay attention to the surface maintenance of the equipment, which directly affects the surface quality of the instruction manual. The key is to treat the rust. Therefore, it is very important to select the same suitable, high-quality and senior grease. S

• Selection of lathe tool holder

  2019 / 11 / 29

  CNC machining is more strict on the rigidity, accuracy, durability and dynamic balance performance of cutting tools. The selection of cutting tools should pay attention to the analysis of the structure and process of the workpiece, combined with the processing capacity of CNC machine tools, workpiece materials and process content and other factors. There are two kinds of structural forms of tool shank in CNC machine tools: integral type and modular type. The working part of the clamping tool of the integrated tool handle is integrated with the handle for installation and positioning on the machine tool. This kind of tool handle has poor adaptability to the transformation between machine tool and parts. In order to adapt to the transformation of parts and machine tools, users must reserve various specifications of tool holders, so the utilization rate of tool holders is low. Modular tool system is a kind of advanced tool system, each handle of which can be assembled by a series of modules. According to different machining parts and machine tools, different assembly schemes can be adopted to obtain a variety of tool shank series, so as to improve the adaptability and utilization of tool shank. The selection of the structural form of the handle should take into account the advanced technology and economic rationality: 1. For some simple tools that are used repeatedly for a long time and do not need to be assembled, it is appropriate to equip with integral tool handles to make the tools rigid and cheap (such as the end milling tool handles, spring collet tool handles and drill collet tool handles for machining the external contour of parts, etc.);
