1. Manufacturing standard: BT handle is Japanese standard mas-403, and JT handle is German standard din69871. There is also a manufacturing standard jisb6339 for BT tool handle. Although the Japanese standard jisb6339 has replaced the standard mas-403 of Japan working machinery industry association, because its main overall dimensions are the same, it basically has no impact on the use. Therefore, many tool manufacturers still mark the mas-403 standard code on their samples instead of jisb6339....
There are two main methods for BT CNC tool holder grinding: One is an ordinary tool with low requirements for overall dimension accuracy and simple blade shape. The user can manually grind the cutting edge through an ordinary tool grinder. This grinding method is characterized by high requirements for the grinding master and must have a certain understanding of the tool. The polished tool can only be used for rough machining. The other is the precision integral tool with complex shape and high...
CNC machining has more strict requirements for tool stiffness, accuracy, durability and dynamic balance performance. The selection of CNC tool holder should pay attention to the analysis of workpiece structure and processability, combined with the processing capacity of CNC machine tool, workpiece material and process content. 1、 For some simple tools that are used repeatedly for a long time and do not need to be assembled, it is appropriate to be equipped with an integral tool handle, so that...

Spring collets are made of high-quality alloy steel with good elasticity. Heat treatment makes the outer cone of the head and the inner wall of the collet have high hardness to ensure rigidity and wear resistance. Spring collets of various sizes can clamp workpieces in the field of small size. Therefore, they are mostly used in safe automatic machine tools. Such as automatic lathe. The spring collet has conventional composition, good rigidity, can withstand large torsion and eliminate looseness...
The manufacturing technology of spring collet is to first add the collet to the pressure cap, gently operate the circlip, wait until the eccentric part of the pressure cap is concave into the circlip groove, evenly and vigorously expand the circlip along the arrow mark, and then the cone can be divided into two halves. The ER collet only needs to move the sliding sleeve, that is, the drilling and tapping sleeves can be reliably replaced. When drilling, Morse sleeve is found automatically; When...
The machining of CNC machine tool and the machining quality of workpiece are also related to the installation of cutting tools. Er extension rod has excellent quality and reasonable price. In addition to matching with major domestic machine tool plants, the products are deeply trusted by users at home and abroad. During use, the materials should be kept dry to prevent rust. For the ER extension rod, the quality requirements are very strict. For the storage of the ER extension rod, if it is not...
The position of collet in machining industry can not be underestimated. Don't look at this small and insignificant collet, it is the key to realize tool machining. The spring collet is also known as the collet, which is not unfamiliar to people in the machining industry. The spring collet is installed on the milling machine. It is a cylindrical fixture used to imprison the drill bit or milling cutter in machining. From another point of view, the spring collet is a fixing device used to fix and...
Collet is a kind of locking device for clamping cutter or cavity, which is usually used in drilling and milling machines and machining centers. Select the quality of the rear pull collet and identify the titanium Hao. The rear pull collet is to pull the clamping part backward after the object is loaded to clamp the collet. The forward push type moves the cavity forward so that the collet clamps the object. At present, the collet material used in the industrial market is 65Mn. Collets are called...
