3d milling is developed from CNC milling machine. The biggest difference with the CNC milling machine is that the machining center has the ability to automatically exchange machining tools. By installing tools for different purposes in the tool magazine, the machining tools on the spindle can be changed by the automatic tool changer in one clamping to realize multiple machining. Features.
3d milling is a high-efficiency automatic machine tool composed of mechanical equipment and numerical control system suitable for processing complex parts. 3d milling is currently one of the most widely used CNC machine tools in the world. Its comprehensive processing ability is strong, and more processing contents can be completed after the workpiece is clamped once. The processing accuracy is high, and the efficiency of batch workpieces with medium processing difficulty is 5 to 10 times that of ordinary equipment, especially it can complete Many processings that cannot be completed by ordinary equipment are more suitable for single-piece processing with more complex shapes and high precision requirements or for small and medium batch production of multiple varieties. It concentrates the functions of milling, boring, drilling, tapping and cutting threads on one equipment, so that it has a variety of processing methods. According to the spatial position of spindle machining, 3d milling is classified into horizontal and vertical machining centers. Classified according to process use: boring and milling machining center, compound machining center. According to the special classification of functions, there are: single workbench, double workbench and multi-workbench machining center. Machining centers with single-axis, dual-axis, three-axis and interchangeable headstocks. According to the classification of guide rails, there are linear rail machining centers, hard rail machining centers, etc.
(1) Expand the scope of CNC lathes and turning-milling machines to realize "one machine with multiple uses". The machine tool is equipped with suitable conversion other tool fixtures, which can carry out corresponding similar machine processing and expand the processing range, such as lathes, radial drills, CNC lathes, workbench boring molds, and drilling machines that can be used when lathes and drilling machines.
(2) It reduces the requirements on the technical level of workers and reduces the labor intensity of workers. Due to the use of mechanical tools, it avoids the limitation of the technical level of the workers and the route, and the influence of the quality of the marking precision parts. The worker's operation can only be good when the workpiece is in the fixture, which ensures the quality of the product and reduces the labor intensity of the worker.
(3) Improve labor productivity and reduce processing costs. The tool used has a short installation time, no need to find it, time mark, some fixtures can also improve the rigidity of the workpiece, which is beneficial to increase the cutting amount and reduce the movement time. If you further use the workpiece clamping and pneumatic, hydraulic quick linkage clamping device, you can Further reduce auxiliary time and improve labor productivity.
(4) Parts with stable quality and machining accuracy are guaranteed. During the cutting process, the workpiece is inevitably subjected to cutting force. Using a fixture, the workpiece is at the correct position without cutting force damage relative to the machine cutting tool. Machining accuracy, when the workpiece is installed on the clamping device on the fixture, this constant position is not affected by subjective factors. For example, the eccentricity of manual scoring and turning in a special fixture is much more accurate.
