1. Do you see that Latin is of the same specification? Maybe there is something wrong with the handle. You can measure it and see
in addition, the claw should be adjusted
2. According to the machining center spindle taper hole is usually divided into two categories, namely taper 7:24 general system and 1:10 HSK vacuum system. Generally, there are five standards and specifications for universal toolholder with taper of 7:24, namely NT (traditional type), din69871 (German standard), is07388 / 1 (International Standard), masbt (Japanese standard) and ANSI / ASME (American Standard). The German standard of NT type toolholder is din2080, which is used to tighten the toolholder on the traditional machine tool through the pull rod, also known as st in China; The other four kinds of toolholders are tightened on the machining center by the pull pin at the end of the toolholder. At present, din69871 (JT) and masbt toolholders are widely used in China. Din69871 toolholder can be installed in din69871 and ANSI / ASME spindle taper hole machine tools, is07388 / 1 toolholder can be installed in din69871, is07388 / 1 and ANSI / ASME spindle taper hole machine tools, so in terms of versatility, is07388 / 1 toolholder is the best< The German standard of HSK vacuum toolholder is din69873, which has six standards and specifications, namely < br > hsk-a, hsk-b, hsk-c, hsk-d, hsk-e and hsk-f. there are three commonly used ones: < br > hsk-a (automatic tool change with internal cooling), hsk-c (manual tool change with internal cooling) and hsk-e (automatic tool change with internal cooling, high-speed type).
3. Er32 refers to the er32 chuck with din6499 standard. Er collet is a kind of cylindrical fixture, also known as Er collet, which is used to imprison drilling tools or milling tools. It can also be used to fix and reinforce a fixed locking device which needs to transform the processing parts. Er spring chuck, large clamping force, wide clamping range, good precision. It is widely used in boring, milling, drilling, tapping, grinding and carving. Er collet is a kind of spring collet, which is generally used for NC tool holder.
4. 1: There is a spring behind the three claws to see if the spring is broken, and the three claws are opened at the end. 2: long term jacking of the tool holder to see if it is shortened. If it is necessary to adjust the length
5. It's estimated that it depends on how strong the impact is. If it's slight, it won't, if it's very serious, it's estimated that it will fall. Just be careful when you operate. Personal opinions are for reference only
6. Tightening or loosening the tool is done by using the cutter cylinder (mechanical type) or hydraulic type. Please check whether the claw of the spindle taper hole is damaged, whether the claw mechanism is composed of four claw pieces and springs, whether the action of cutting and loosening is normal, and whether the distance is normal. The spindle has two dimensions of 92.9mm and 93.6mm. Please use a depth gauge to measure from the spindle section to the claw section
because the torque is transmitted by the keyway on the cylinder at the front end of NC5 toolholder, and there is no keyway at the end of toolholder to transmit torque, the axial dimension is shorter than that of HSK toolholder
the biggest difference between it and the previous two toolholders is that the toolholder does not adopt thin-wall structure, and a middle taper sleeve is added at the taper surface of the toolholder. Km toolholder and HSK toolholder compensate the manufacturing error of toolholder and spindle through thin-wall deformation, and ensure the reliable contact of cone and end face at the same time. NC5 toolholder achieves this goal through the axial movement of the middle cone sleeve
extended data:
HSK toolholder adopts short conical surface and flange end face positioning at the same time, the toolholder is hollow structure, short conical taper is 1:10, and the toolholder and spindle are locked by expansion elastic chuck
There are two main failure modes of HSK toolholder in the working process: one is that the material strength of the toolholder is insufficient and it is damaged under the action of huge centrifugal load; Secondly, the high-speed rotation reces the dynamic clamping force, so that the clamping system can not provide enough clamping force to ensure the smooth cutting. Therefore, the calculation of HSK toolholder critical speed should be analyzed from two aspects of material strength and clamping force
after the parts are clamped once, the CNC system can control the machine tool to select and change the cutting tools automatically according to different processes; It can automatically change the spindle speed, feed rate, tool relative motion path and other auxiliary functions of the machine tool. It can automatically drill, countersink, ream, bore, tap thread, mill and other processes on each processing surface of the workpiece
7. 1) Many factors need to be considered in the selection of toolholder structure. For some simple toolholders that are used repeatedly for a long time and do not need to be assembled, such as face milling toolholder, spring chuck toolholder and drill chuck toolholder used for machining on the outline of parts, integral toolholder is suitable. In this way, the tool is rigid and cheap. When machining multi variety and small batch parts with constant change of hole diameter and depth, molar tools should be selected. This can replace a large number of integral boring tool handles. When more machining centers are used, molar tools should be used. Because the selection of molar tools can make the intermediate mole (connecting rod) and working mole (tool loading mole) used in each machine universal, which can greatly rece the equipment investment, improve the utilization rate of tools, and is also concive to the management and maintenance of tools.
8. This kind of situation generally occurs in the machining center quality is not very good common. Generally more than 1 million, this problem is not much... The reason is because the spindle cone hole and Latin fixed when the air pressure is constant, but in the process of processing, e to the processing capacity is too large, generally milling cutter. It causes the tool taper handle to heat up and cause micro expansion. So that it fits too tightly with the taper hole in the spindle. Therefore, when the knife can not be manually taken down, mainly with a copper hammer and other things to help beat
9. The standard taper of toolholder in machining center is 7:24
machining center (abbreviated as CNC, full name as computerized numerical control): it is a highly automated multi-function CNC machine tool with tool magazine and automatic tool changing device. In Hong Kong, Taiwan and Guangdong, many people call it a computer gong
after the workpiece is clamped once in the machining center, the digital control system can control the machine tool to automatically select and replace the tool according to different processes, automatically change the spindle speed, feed rate, the movement path of the tool relative to the workpiece and other auxiliary functions, and complete the multi process processing on several surfaces of the workpiece in turn. And there are a variety of tool change or tool selection functions, so that the proction efficiency is greatly improved.
10. Press the single section operation key --- when the machine tool stops --- turn the mode switch to the handwheel --- clear the relative coordinate --- press the spindle stop key (some machine tools will not stop, but can only stop after reset). If the blade is replaced and replaced, open the spindle and move the coordinate to the relative coordinate x0y0z0 point with the handwheel. At the beginning of the mode, turn to the auto start program button. Some machine tool mode switch is the key, switch to manual mode will automatically reset.
