Characteristics of machine tools:

Based on manual surface grinder, it covert the longitudinal and vertical machine to fully automatic The bidirectional friction electronic clutch, simple and reliable structure, clutch reversing process has no impact, no noise, safe commutation 5000000 times; the electric control part with electronic switching frequency switching, The service life 10 times longer than the relay control, simple operation, sensitive, infinitely variable; large output torque, low noise, Safe and reliable.  Power supply use a number of mechanical and electrical protection function which is safe voltage, Energy saving, power saving, power consumption per class (calculated according to 8 hours) is only 0.6.When the manual grinding is working,Before and after the workbench’s movement, in and out, around the reversing are automatic operation, greatly improving the

production’s efficiency and the surface finish, suitable scope that from the original single, small  batch to mass batch.

 

机床特性:

     是在手动平面磨床的基础上,将工作台手动的纵向运动机构和横向运动机构转换为全自动.采用双向摩擦电子合器,结构简单、可靠,离合换向过程无冲击、无噪音,可安全换向500万次以上;电控部分用电子开关实现频繁切换,寿命比继电器控制长10倍,操作简单项、灵敏、无级变速;输出力矩大,噪音低。安全可靠,使用电源为安全电压,且使用多项机械、电子保护功能。节能、省电,耗电量平均每班(按8小时计算)仅为0.6度。使手动平磨在进行磨削时,工作台(工件)左右和前后的运动、进给、换向实现自动化操作,大大提高了生产效率和磨削光洁度,使的适用范围由原来的单件、小批量磨削扩大到大批量磨削。
