WFL company puts forward Mechanical Bearing 6901 of ‘install the card once and complete it all’. M40G This turning and milling center integrates a dual-spindle turning center, a five-axis machining center, deep hole boring, milling, drilling and three-axis functions in one. It can fully process the crankshaft on a dual-spindle turning-milling composite machining center , The processed crankshaft can be directly transferred to the finishing process. At present, a similar compound machine tool has been introduced in China. During CIMT2005, the CKZ80-5 turning and milling machining center exhibited by Shenyang CNC Machine Tool Co., Ltd. is a compound machine tool, representing the highest level of similar machine tools in my country. The X, Y, Z, and B axes of the machine tool are detected by linear grating ruler or round grating ruler, which can realize closed-loop control.
The machining center is equipped with a 48-96 station tool magazine that can realize automatic tool change, and can carry out turning, milling, drilling, boring, tapping, etc. processing at one time. In terms of crankshaft finishing, CBN CNC grinders with integrated processes have also appeared, that is, grinding all crankshaft main journals and connecting rod journals at one time. Such grinders are generally equipped with double grinding wheel headstocks.
Such CNC grinders produced by Japan TOYADA Machinery, Germany JUNKER, Germany NAXOS, etc. are relatively mature equipment. Here is a brief introduction to the performance of the GF70M-T crankshaft grinder developed and produced by Japan’s TOYADA Machinery: This machine tool is a CNC crankshaft grinder designed to meet the needs of multi-variety, low-cost, high-precision, and mass production. It uses workpiece rotation and grinding wheel processing.
Thanks to the servo linkage control technology, the grinding of all journals can be completed in one clamping without changing the crankshaft rotation center, including follow-up grinding of connecting rod journals; using hydrostatic spindle, hydrostatic guide rail, and hydrostatic feed Screw (grinding wheel head) and linear grating closed-loop control, using GC50CNC control system produced by TOYADA machine, grinding journal roundness accuracy can reach 0.002mm; using CBN grinding wheel, grinding linear speed up to 120m/s, with double The grinding wheel headstock has extremely high grinding efficiency. Diversification of tool materials in crankshaft machining
