• The difference and use of boring cutter and milling cutter

  2021 / 01 / 12

  Usually we use the rough boring cutter, which is basically round handle. We use more when processing and expanding the inner hole. So what's the difference between the boring cutter and the milling cutter? About boring cutter: Boring cutter is a kind of boring cutter. Because of the different clamping methods, the toolholder has square handle, taper handle and other forms. The rough boring cutter can not only be used to process the inner hole, but also the outer edge of the end face. It needs to be pre adjusted before using the boring cutter, and the dimensional accuracy should meet the requirements. Boring cutter is a kind of boring cutter, which is usually round handle, but also large workpiece. Square cutter bar is commonly used in vertical lathe, and the common occasions are inner hole processing, reaming, profiling, etc. However, it is not only able to process the inner hole, but also the outer circle of the end face, which is not used in this way About milling cutter: Milling cutter is a kind of forming cutter, which is mainly used for milling, with one or more cutter teeth. The types of milling cutter include cylindrical milling cutter, face milling cutter, etc. milling cutter is mainly used for machining plane, forming surface and cutting workpiece on milling machine. There are two kinds of milling methods: forward milling and reverse milling. The geometric shape of the machined part is the main basis for selecting the tool type.

• How to choose the structure classification of CNC toolholder

  The structure of tool holder of CNC machine tool is divided into integral type and modular type. The working part of the clamping tool of the integral tool handle is integrated with the handle used for fixing and positioning on the machine tool. This kind of toolholder has poor adaptability to the transformation of machine tools and parts. In order to adapt to the transformation of parts and machine tools, users must reserve various specifications of toolholders, so the utilization rate of toolholders is low. Modular tool system is an advanced tool system. Each tool holder 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 toolholder series, so as to improve the adaptability and utilization rate of toolholder. The selection of tool handle structure should take into account the advanced technology and reasonable economy ① For some simple tools which are used repeatedly for a long time and do not need to be assembled, it is better to equip with integral toolholder to make the tools rigid and cheap (such as end mill toolholder, spring collet toolholder and drill collet toolholder used to process the outer contour of parts); ② In order to reduce the processing cost, modular toolholder should be selected to replace a large number of integral boring toolholders when machining multi variety and small batch parts with constant change of hole diameter and depth; ③ There are many CNC machine tools, e

• Selection and use of powerful milling tool shank

  In the actual field processing, the use of powerful milling tool holder is very common, and it is used as the basic tool holder by many users. Today, Sheng Anbei is going to talk about some key points that are not usually mentioned. Selection and use of powerful milling tool shank 01. About clamping force It is difficult to answer the question of "how much kg · m clamping force is needed for low Zui". It is easy for users to fall into the misunderstanding of judging the quality of powerful toolholder according to the nominal holding force in the samples of various brands. In fact, it can not be simply said that a good toolholder has a large holding force. Take big dazhaohe powerful milling tool holder with clamping force of 300kg · m as an example. In practical use, the actual cutting torque of Φ 32 milling cutter is no more than 60kg · M. even considering the safety rate, 250kg · m is completely enough. However, in addition to the clamping force, the following points are more important! 02. The inner diameter has enough shrinkage In practical application, there are many occasions where the tool shank diameter is close to the lower tolerance limit and is used with the reducer sleeve. At this time, no matter how big the clamping force is, only when the gap between the inner wall of the handle and the reducing sleeve, and the gap between the reducing sleeve and the handle of the cutting tool is zero, can the clamping force be generated and the cutting tool be clamped. According to the calculation, if the
