Based on their well-established "Deckel-type" precision Universal milling machines, in the late 1970s Maho began to offer a series of models fitted with first NC and then CNC controls. By the early 1980s, the machines had been divided into three ranges, the MH-P, MH-C and MC. The MH-P machines, MH-400P, MH-600P and MH-800P, were the introductory models and equipped as standard with a CRT screen (though optional on the model 400), CNC positioning and a "straight cut" control system. A single DC motor provided the drive that passed through electro-magnetic clutches and ordinary Acme-form feedscrews.
The more advanced MH-C range, consisting of the MH-400C, MH-700C and MH-900, these being CNC machines offered with full contouring control in up to four axes and equipped with CRT screens as standard; powerful variable-speed DC motors were fitted and drove through zero-backlash recirculating ball screws. Confusingly, two models in the Series carried a P suffix and were less well specified, having just straight cut control and basic CRT screens.
Machines in the MC range were quite different and classified as Horizontal machining centres; two models were offered, the compact MC500 and the MC600, the latter fitted as standard with a pallet changer and available with further options such as loading by robot and a pallet shunting station.
