Slant bed CNC lathe manufacturer analysis of CNC lathe tool holder system
Slant bed CNC lathe manufacturer analysis of CNC lathe tool holder system release time: 2016 - 02 - 18 clicks: 2678 times of CNC lathe tool carrier is an important part of CNC lathe. Rest for clamping cutting knives, so its structure directly affect the cutting performance of machine tools and cutting efficiency. To a certain extent, the structure and properties of tool post reflects the machine tool design and manufacturing technology level. With the continuous development of numerical control lathe, cutting tool structure have been renovated. Tool rest is direct execution of finish machining parts, so the head must have good strength and stiffness in the structure, to withstand the rough machining of cutting resistance. Due to machining accuracy depends largely on the tip position, so ask CNC lathe reliable positioning scheme and choose the reasonable structure of positioning, to ensure that there are high repeat positioning accuracy. In addition, the design of the tool rest should satisfy tool change time is short, compact structure and safe and reliable. Slant bed CNC lathe manufacturer according to the different methods of tool change, numerical control lathe tool holder system mainly include rotary tool rest, rest and take knife library automatic tool change device such as a variety of forms. 1, the row type tool carriage row type CNC lathe tool rest are used for small specification, mainly processing bar or plate parts. For its structure form, with various different USES tool clamping toolholder along the X axis direction of the machine tool is arranged on the transverse slide. This tool post decorate in the cutting tool and machine tool adjustment, etc are more convenient, can according to the requirements of the specific workpiece turning technology, any combination of different USES of cutting tool, a tool cutting task finished, transverse slide as long as according to the preset program along the X axis distance, after the first ErBaDao to reach processing position, this completes the tool change machine. This way of tool change quickly to save time, improve the production efficiency of machine tool. 2, rotary head rotary tool carrier is the most commonly used one kind of typical for CNC lathe tool rest, with the rotation of the tool post graduated positioning to achieve the automatic tool change machine action, according to the processing requirements can be designed into four, six party head or disc type tool post, accordingly to install 4, 6 or more rest. Rotary tool carriage tool change action can be divided into the tool post lift, tool post transposition and tool slide lock several steps. It is made by CNC system instructions. Rotary tool post according to head back to the bottom of shaft and installation of the relative position, divided into vertical tool rest and two horizontal tool slide. 3, with a knife library automatic tool change device installed by the row of knife rest and rotary tool rest tool cannot too much, even if is equipped with two head, also have a certain limit to the number of the cutting tool. When, for some reason need quantity more knives, knife library automatic tool change device should be adopted. With a knife library automatic tool change device consists of knife library and tool exchange mechanism.
