EHSerieS

Working table provides efficient pallet change, no need for table return to origin before pallet change.

All accessories like hydraulic unit,cooling unit, chip conveyor and CTS ( opt. ) are integrated with rear exit design coolant tank achieving minimum foot print requirements.

X / Y / Z axes are driven directly by servo motor, provides brisk fast feed at 60 m/min. Cutting feed rate also reaches 15 m/min.

Combining design concepts of compact structure, high speed

machining and ergonomic operation. EH series is developed for

high efficiency mass production applications. Very suitable for

automobile parts, hand tools, valves, and parts with quantity.

Spindle nose tip to center of table is only 150 mm, work piece could be finished using shortest tool possible for best cutting rigidity.

Unique headstock design, even when the Z-axis is fully extended still maintains minimum sagging.

EH-400 / EH-500SUPER RIGID STRUCTURE

The Finite Element Analysis ( FEA ) provides optimum machine design and light-weighted structural advantages to ensure the best machine rigidity.

Built to endure years and years of rigorous high production milling, the heavily ribbed,one-piece thermally balanced bed and casting components are of Meehanite casting.

* HEIDENHAIN high accuracy linear scale is optional available for order.

Chip Removal

Complete chip flushing system will rapidly take out cutting chips with high temperature via trough in the center of base, maintaining ultimate cutting accuracy.

Big coolant tank at 685 L capacity provides best cooling effect. The extra space needed for coolant tank pull out for cleaning is merely 1,000 mm. Saves precious time and space in factory for routine maintenance.

Rear exit chip conveyor arrangement can easily integrate with centralized chip conveyor. Most suitable for in line production arrangement.

Standardly equipped coolant level gauge with big visible window provides operator ease of inspection and maintenance.

High Performance Spindle System

The inner taper of the spindle conforms with BBT tool to provide a firmer grip to the tools which reduces the vibration from the tools.

Large size spindle bearings with optimized span arrangement greatly increase rigidity. Which could meet requirements all kinds of cutting condition.

Direct-drive spindle efficiently separates the heat generated from the motor, which reduces deformation, increasing machining accuracy.

12,000 rpm and 15,000 rpm are available, which to meet with various high speed working conditions.

Automatic Pallet Change System

Standardly equipped with two tables pallet system, when machine is performing cutting can simultaneously prepare the set up for next work piece. Greatly increase the output e�ciency.

One piece casting base provides abundant support for APC system. Table design provides e�cient pallet change, no need for table return to origin before pallet change.

APC table change is driven by servo motor via cam system, stably achieving table change at maximum capacity at 600 kgs ( EH-500 ).

7

The clamping mechanism uses a four hydraulic cylinder and cone seat design which provides stable machine accuracy and ample clamping force to the work table.

The cone seat uses air blow cleaning and air pressure detection mechanism in order to enhance the clamping reliability and position accuracy.

0.001 degree indexing B-axis rotary table provide high speed, high accuracy index positioning. ( standardly equipped with B-axis encoder )

High precision two-piece worm gear mechanism has contact teeth and contact area that are twice as more compared to conventional designs, ensuring table rotation accuracy and the ability to provide complex work-piece machining.

Hydraulic brake system with full circumference will help prevent deformation of the brake disks due to its super rigidity characteristics and heavy cutting durability.

8

Reliable ATC System

The servo driven arm-type 24T ATC is highly e�cient and reliable. 32T chain type tool magazine is optional available to ful�ll all kinds of cutting requirements.

Tool magazine arrangement on top of machine greatly reduce the machine occupied area. Provide production line arrangement �exibility.
