　Easson ET-400HR tool presetter is intended for improving efficiency of CNC machining center, it has the advantages of being easy-operating and high precision, the whole presetting Process does not need to be done on CNC machine, so greatly reduce the stopping time.
　　Comparing with traditional presetter, ET-400HR can improve the efficiency at least more than two times.
　　For common parts processing, ET-400HR can increase the efficiency by at least 5%. Because the whole presetting process (for example, measurement for compensation length, diameter etc.) is going on without the machine, no need to stop CNC machining center to tool presetting, so even if user has many CNC machining center, he only needs one ET-400HR to do all workshop’s presetting work.
　　Operation of ET-400HR is very simple and direct, ET-400HR is equipped with a precision standard cone as its benchmark zero, The digital readout counter of ET-400HR takes the standard cone as 0.000, the size difference between all measured tool and the standard cone is tool compensation data, which can be input directly in controller of CNC machining center.
