. Machine Structure
Machine base and travelling column are made from high strength cast iron to maximize machine stiffness
and damping.
• Machine is designed using Finite Element Method (FEM) software for rigidity and FEM analysis. The
end result is an optimum combination of structure, accuracy, reliability and price / performance ratio.
• One-piece T-shaped base with box-type construction and rib reinforcement, to maximize rigidity and
stability.
• Base has three-point leveling, with four secondary supporting pads, for ease of installation and
maintenance.
• Travelling column with double-wall design and stepped X axis linear guides, to improve rigidity and
machining stability.
• Main base includes twin chip augers to direct the chips to the rear of the machine.
• Thermal stabilization by coolant flushing of lower base.

. Linear X, Y and Z Axis
• All linear axes are equipped with generously sized precision THK linear guides and preloaded linear
bearing packages, providing fast 60 m/min traverse speeds.
• Automatic oil-air lubrication system for ball screws.
• Automatic central lubrication system for linear guides.
• Single ball screw drive in the X, Y, and Z axis.
• Servo motors are direct coupled to the ball screw drive to eliminate the risk of drive failures.
• Y axis ball screw saddles are secured during a power-off condition by a servo motor / brake
combination.
• Available options:
o Absolute linear glass scales to eliminate the effects of temperature variation and minimize the
need for start of shift warm-up cycles or to re-calibrate the axis home position after the return of
power. Linear scales are provided with an air purge circuit to protect the scales from coolant
contamination.

7. Spindles
The MMH 500 is available with a standard 12,000 RPM high performance motorized spindle to provide
the RPM and torque required for the application.
MAG spindles offer the following features:
• CAT 40 tool taper
• 22 kW (30 HP) (15 min. rating).
• Integral AC servo motor for optimum acceleration.
• High precision angular contact ball bearings, arranged to maximize spindle stiffness.
• Greased-for-life ball bearings.
• Closed loop circulating oil cooling system with isolation of motor heat from the spindle bearings.
• (4) Coolant flush holes thru front of spindle housing.
• Air blow-off of the tool seating flange during tool change.
• Disc spring clamp and hydraulic unclamp of tool collet for maximum reliability.
• Air purge to prevent coolant ingress.
• Prepped for optional high pressure coolant thru the spindle.

8. Tool Storage and Automatic Tool Changers
The MMH 500 machine is available with a standard 40 tool, chain style magazine with floor level tool load.
• CAT 40 tool taper
• Tool capacity: 190 mm (7.48 inch) diameter, 550 mm (21.65 inch) mm length, 12 kg (26.4 pounds)
weight.
• Indexing of the chain is accomplished via a servo motor-driven, rotating cylindrical cam. The chain is
guided by a series of roller followers mounted to the chain, which follow a solid track.
• Pneumatic cylinder releases the chain gripper from the cutting tool flange at tool exchange position.
• Pneumatic tool shuttle mechanism to remove the tool from the tool magazine and place it in position
for pickup by the swapper arm.
• Pneumatic cylinder opens and closes the vertical tool change door.
• The new tool is unloaded from the tool shuttle mechanism via a servo motor-driven, cam operated
swapper arm, which removes the new tool from the tool shuttle and rotates 180° to position the new
tool in front of the machining spindle, before inserting the new tool into the spindle. The “old” tool is
simultaneously removed from the spindle and placed in the tool shuttle mechanism with the other end
of the swapper arm.
• Pneumatic mechanism to disengage tool from tool magazine so operator can remove and replace
cutting tools.

9. Rotary Table for Pallets
The machine includes an infinite B-axis rotary table.
• 22 RPM direct drive contouring table.
• Worm gear drive with zero backlash.
• Hydraulic table clamping in cutting position.
• Pallet clamping to the table provided by (4) cones that provide high clamping forces without distortion
of the pallet.
• Air blow off thru the tapered cones.
• Air switch to confirm pallet seating.
• 600 kg (1,322 lb.) fixture payload on pallet.

10. Pallet Changer
• The machine includes a (2) position rotary pallet changer.
• The pallet changer mechanism provides 8.5 second pallet change time via an overhead hydraulically
driven rotary index unit and hydraulic lift and lower mechanism.
• Seal plate is provided to isolate the work area from the work piece load / unload area of the machine.
• Manual pallet indexing at the load station to provide access to four sides of the work holding fixture.
• Index times without fixture: 90° = 2.0 Sec. / 180° = 3.0 Sec.

11. Pallets
• The machine includes (2) 500 mm x 500 mm pallets with (24) M16 x 2.0 tapped holes.
• Pallets have side locator plates to use for fixture location.
• Available options:
o T slot pallets to replace standard tapped mounting holes.

12. Electrical System
• Designed and built to North American controls standards.
• The machine is provided with a power distribution panel to house the CNC, servo drives and
associated I/O, motor starters and fuses.
• Panel assembly is NEC, NFPA 79 and UL compliant, 508 A/SB Designed to 65 KA.
• Dual-check safety system included (Dual-channel guard safety lock switches provided).
• Electrical Connection 400 / 460 V Wye AC 3 Phase ± 10%, 50 / 60 Hz ± 10%.
• Direct connect 480V electrical power to machine, eliminating the need for an isolation transformer
• Cooling via a panel-mounted air conditioner.
• Main electrical cabinet provided with door interlock.
• The electrical system will operate with an ambient temperature between 41°F (5°C) and 104°F (40°C)
with a maximum average temperature of 93°F (34°C) during a 24 hour period and a maximum relative
humidity of 95% at 104°F (40°C) according to EN60204.
• Connection load 60 kVA
