MDH Series – Horizontal Machining Centre

Model : MDH40,...

The MDH Series is the ideal machining center for producing box-type and irregular work pieces for automobile, shipbuilding, engine and general engineering industries. The machine is a high-performance, high-reliability and high-precision product characterized by a compact configuration and rapid response rates. The spindle design makes it particularly suitable for heavy power cutting while the excellent ball screw & spindle cooling system provide superb capability for flexible manufacturing.

High-speed High-power Spindle

The high performance, programmable two speed integrated electric spindle motor means that the MDH is not only capable of high-speed, high-power cutting, but also provides excellent low-speed high-torque cutting.

Compact Configuration and Unrivalled Rigidity

The machining center is constructed from thick wall box castings providing exceptionally high rigidity. The extra thick castings of the base and column Improve rigidity, and control thermal deformation to a minimum thus keeping exceptionally high precision over extended periods.

The unique configuration of the MDH horizontal machining center in which the X-axis moves left and right and Z-axis moves the table forward and backward makes the machine work more effectively. The compact configuration also means that the machine takes up 30% less space than former
machining centers and makes the machine particularly suitable for machining automobile engine cylinder body, large steel components, casting and Aluminum components.

High-speed ATC

The fully mechanical, cam-operated, ATC system ensure high-speed accurate tool changing with high durability. The cam provides a variable-speed function so that heavy tools are changed smoothly while the single-motor system ensure complete synchronization of the tool clamp/unclamp operation during high-speed ATC operation.

Combined with a high-speed automatic shutter, the ATC completes a tool-to-tool change in 2/2.5 seconds, while the cassette-pot magazine design permits flexibility for tool capacity expansion, and boasts a top-class tool weight capacity of 25kg.

High-speed APC

The direct-drive APC mechanism is designed to lift and rotate only, thus achieving an APC time of only 12.5 seconds as well as accurate table changing operation.

A multiple APC system (8 or 10 pallets) can be provided to add flexibility in future system expansion and line configuration. Maximum table loading is 2000 kg.
