YH2M8426A高精度立式平面研磨抛光加工机技术特点：Technical characters:
1.本机床属于4道行星轮系运动原理的研磨机床。
2.本机托盘重量通过空心轴、固定套配成对锥轴承和三个支撑脚全部落入底板，可以保证*的托盘端跳。
3.齿圈、下研磨盘、上盘与太阳轮各用一个减速机，各减速机轴线与传动轴线具有好采用变频器调速，起动及停车平稳、无冲击。
4.机床在工作时通过在人机界面编辑好加工程序，本机可以编辑100个程序。
5.本机床配有对工件加压研磨的压力检测机构，自动检测工件当前所受压力。
6.本机配有安全自锁气缸，当上研磨盘上升到上限位点时，勾板挂上，防止上研磨盘落下，确保操作者、设备安全。
7.采用PLC控制，控制方式灵活可靠。
8.用触摸屏做为人机界面显示报警和机床状态的实时信息；介面友好，信息量大。
＊注：压力检测系统为选配。
1.The movement principle of 4 planet gears.
2.Ensure tray’s high run-out and stable, the weight of tray is distributed to the base plate through hollow shaft, cone bearing and three supporting legs.
3.Exclusive reducer and frequency converter regulating, there is one for each ring gear, upper plate, lower plate and sun gear, and the machine starts and stops smoothly.
4.Programmable, it is easy to program on interface and it can add 100 programs.
5.Pressure detecting mechanism, automatically detect the pressure of work piece.
6.Self-lock cylinder, when upper plate goes up to upper limit, hook will catch it for ensuring operator’s safety.
7.PLC controlling, which it is flexible and reliable
8.Touch screen, it is convenient to show alert information and state. Besides, the interface is friendly and the information is huge.
* Pressure detecting mechanism is optional.
