M: M series are 3 axes by manual.          
H: H series are longitudinal by hydraulic and cross feed / vertical axes are manual.
AH: AH Series are auto. Cross feed, longitudinal by hydraulic and vertical axis is manual
AHR: AHR Series are auto. Cross feed, longitudinal by hydraulic and vertical axis travel is by AC servo motor.
The manufacturer reserves the right to modify the design and mechanism specifications, etc. without prior notice.
Above the 5010AHR Series are equipped with auto. Cross feed, longitudinal by hydraulic, vertical axis drvien by Ac servomotor and operated by MPG. The AD5, (designed by PROMPT) can be added to become 3 axes fully automated thereby making operation more convenient.
