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...
Manufacturing technology of spring collet: firstly, put the collet into the pressure cap, work the circlip gently, when the eccentric layout of the pressure cap is concave into the groove of the circlip, place the forceful circlip along the arrow positioning, then the two halves of the cone can be achieved. The ER collet needs to be turned to the sliding sleeve, that is to say, the drilling and tapping sleeve can be reliably replaced. When drilling, the Morse sleeve is fully automatic locked;...
The spring collet holder is a kind of cylinder-shaped clamp used to imprison the drill or the milling cutter. The collet is installed in the lock nut, and then the lock nut with spring collet is lightly screwed on the tool handle, extension bar or main shaft. It is easy to loosen and fasten by elastic spring steel. It is mainly used to hold light and medium load cutting tools. It is often used to clamp end mills, drills, taps, reamers, center drills and other cutting tools. Change the clamping...

The clamp structure of spring collet is very important for metal workpiece machine tools, especially for bar automata. However, some of their parts are often damaged, so the chance of Turing machine strike caused by clamping organization is often very small, so the spring chuck is a key machine tool accessory among all parts of clamping group. It is practiced under slight motion conditions and determines the precision of grinding. Therefore, it is very important to confirm the basic parameters...
In the high-end manufacturing and processing technology, it is inseparable from the advanced CNC machine tools. In addition to the system, the high-end CNC machine tools, high-precision and stable chucks, tool handles, and CNC tool accessories are also very important in the processing of CNC machine tools. It can be said that a good CNC tool is the teeth of a CNC machine tool. A good CNC tool needs to be equipped with a good chuck, tool handle, and CNC tool to give full play to the superior...
1. tool holder spring collet chuck It is mainly used for clamping straight shank cutters and tools such as drills, milling cutters and taps. The elastic deformation of the circlip is 1mm, and the clamping range is 0.5-32mm in diameter. 2. Hydraulic collet chuck A-lock screw, use Allen wrench to tighten the lock screw; B-lock the piston and press the hydraulic medium into the expansion chamber; C-expansion chamber, compressed by liquid to produce pressure; D-thin expansion bush, during the...
In the actual field processing, the powerful milling shank is widely used, which is used by many users as the basic shank. Here are some key points that will not be mentioned in the sample. (1) about clamping force It is very difficult to answer the question of "how much kg · m of clamping force is needed at least" (in order not to drop the knife) ". Tool holder of a powerful milling cutter with a clamping force of 300kg · m as an example, the actual cutting torque of a Φ 32 milling cutter is...
Most JT tool holders have internal cooling channels to support cooling in the spindle center or (and) the spindle end face. The main structure is shown in the figure below BT handle is a Japanese standard, the shoulder size is larger than JT, so the blade weight is increased, there is positioning around 180 degrees, and there is no positioning gap adverse to dynamic balance. Most of the BT tool holder do not have internal cooling channels, and some can provide BT tool holder with internal...
In addition to the application effect at the end of indirect impact of spring collet quality, it is also the focus of customers' selection. What points should manufacturers pay attention to when grinding? As a professional manufacturer, we get the following key points: 1. For the conical surface of the finish turning collet, the thread tire is used to ensure the machining accuracy of the collet body on each surface of the finish turning. After the holes are equally drilled, the element conical...
ER spring chuck system has been widely used in machine tools all over the world due to its good scalability and accuracy. As a daily tool, how to choose and install each component correctly is very important. However, whether you are a senior engineer or a novice, you may think more than once about the question, "Is the right chuck I use?"
