Horizontal 5 axes Machining Centers

Combining advanced 5 axes control technology and our extensive horizontal machine development experience, EH5 series' powerful 5 axes simultaneous machining capability can overcome any difficult cutting tasks and realize unlimited possibilities.

Super rigid headstock structure

The unique headstock and saddle design maintains excellent structural rigidity even with the Z-axis fully extended.

High performance A / B axes trunnion table

With a maximum cutting torque of 9,700 Nm and 0.001° B-axis indexing, the EH5 series provides heavy cutting and high precision capabilities.

Work table variation

A variety of work tables is available for the EH series, offering a perfect solution to precision mold making, mass production and any other task.

Unit : inch

Compact design

The compact, minimal footprint design effectively raises the factory floor utilization and allows for the setup of an automated production line even in the small workshops.


Super Rigid Structure

Finite element analysis

The Finite Element Analysis provides the optimal machine design to build a light-weight, yet super rigid machine structure.

One-piece casting structure

Using high grade MEEHANITE casting to produce the heavily ribbed, one-piece, thermally balanced machine bed and other structural components, the machine is built to endure years and years of rigorous milling.

Moving column structure design

The highly rigid, yet light weight column structure provides efficient support for the headstock and ensures excellent dynamic performance of the X / Y / Z axes movements, thus effectively shortening cycle times.

High speed, high precision axial feed system

• High speed, low friction linear guide ways are used on X / Y / Z axes to provide optimum motion control and efficient movements.

• Direct drive servo motors with C3 grade ball screws guarantee long term, high precision contour machining capabilities.

• Optional high resolution optical linear scales provide even higher precision.

High rigid headstock

• The optimized headstock and saddle design minimizes sagging to achieve excellent machining accuracy, even when the Z-axis is fully extended.

• The spindle nose can extend to within 5.9" of the table center, enabling the usage of shorter tools and raising cutting rigidity.


High Performance Spindle System

• 12,000 rpm and 15,000 rpm direct drive spindles are available to meet a variety of processing requirements.

• The spindle is equipped with P4 grade ultra-high precision bearings with optimized span two points support, fulfilling heavy cutting and long-time high speed cutting requirements.

• The connector plate between spindle and motor is actively cooled to prevent heat transfer. This reduces thermal distortion and improves machining accuracy.

The spindle and the FANUC spindle motor are connected with a high grade coupling.


Diversified Work Table Modules

A / B axes trunnion table

• The Ø 400 mm B-axis embedded table design can be combined with a fixed table to increase the processing area for better machining flexibility.

• A / B axes with high resolution closed loop rotary encoders ensure ultimate positioning and repeatability accuracy.

High performance B-axis drive mechanism

• High rigidity two-piece worm gear design. The contact area is more than five times that of conventional designs, delivering twice the torque output with high precision, high transmission efficiency, and low wear.

• The fully circumferential hydraulic brake system effectively prevents disk deformation due to unbalanced torque, achieving high rigidity and heavy duty cutting performance.

*1 The worm gear contact areas are designed with a lowpressure angle, providing higher torque output.

Automatic pallet change system

• The work table seat in the processing area is equipped with four hydraulic clamping mechanisms and tapered positioning cones that provide efficient clamping and accurate positioning for the table.

• Air blast cleaning of the positioning cones and monitoring the seal air pressure ensure reliability and durability of the pallet changer.


High Reliability Tool Change System

• The 24T disk type tool magazine combined with the arm-type automatic tool changer shortens the tool exchange time, thereby enhancing overall processing efficiency.

• Two way arbitrary tool selection (Std.) : the tool magazine automatically selects the shortest rotation direction to rotate the tool to the exchange position, further reducing tool exchange times.

• Pre-selecting a tool ( moving it to the tool exchange position prior to the actual tool exchange ) does not interrupt the machining operation and can save even more time.

• On request a 32T disk type magazine or a 50T chain type magazine are available.

Chain type 50T magazine

Top type design

• Minimized foot print.

• More compact production line arrangement.

• The automatic tool magazine door avoids contamination of the tools or the ATC by blocking cutting fluid and chips.

Disk type 24T magazine

Dual contact spindle taper design

The EH5 series employs the advanced Dual Contact Spindle taper design, which not only avoids the taper run out but also enhances cutting rigidity. This is especially suitable for high speed machining. (Std.)

( BBT, BCV, BDV, etc. can be selected according to actual demands. )


Chip Removal System

The advanced chip flushing system assists in maintaining ultimate accuracy, achieving long term machining reliability, and reducing downtime for manual chip removal by rapidly cooling down work-piece and tool while simultaneously removing chips.

The rear-exit coolant tank and chip conveyor design can easily be integrated with a centralized chip removal system, suitable for automated production line arrangements.

Large coolant tank with 685 L capacity and a large surface area for best cooling results. The roll-out design makes maintenance faster and easier.

The nozzles of the chip flush system can be adjusted to reach any position inside the machine, avoiding chip pile up and providing the best cooling effect at the same time.

The central chip channel is covered by stainless steel; the smooth surface greatly reduces the probability of a chip pile up inside the machine.

Optimum operability

• Ergonomics were taken into account while designing the machine to make work-piece setup fast, convenient, and safe.

• All models are designed with large doors and overhead clearance to allow for work-piece loading and unloading by crane or robot arm, which reduces the operator's workload.

Swiveling operator panel and
large impact resistant windows.

Easily accessible pneumatic control unit.

Independent work table exchange operation panel.
