Regid & Accurate Frame of Cast Iron Enables Stability

3 sets of massive frames resist deflection and reduces vibration

6 Points of Crank Supporting (New)

The shortened distance between supports resist deflection
2 bearings and 4 brass bushings are used reducing clearance and resisting wear


Eccentric Shaft		CrankShaft

Eccentric Shaft

The strength of eccentric shaft is more than general crankshaft
Eccentric shaft are known to have strength than a crankshaft


Normal Clutch		Separated Clutch & Brake

Separated Clutch and Brake Enables

Quicker Breaking
Balanced Load

Dynamically Balanced Counter Weight

Dynamic balancer reserves weight of upper die (4%o of press tonnage) to eliminate the inertia produced by high speed reciprocation. Hence, vibration can be reduced to an extremely low level

Slide Quick Lift Mechanism (New!! Optional)

The height of slide quick lift is 70 mm. It helps to solve tooling problems such as material sticking, tool jamming, scrap pulling or punch changing, quickly
After trouble shooting, return the slide to its original height by the push of a button, and the B.D.C. is maintained without readjusting

Colorful Computer Control System

Colorful TFT-LCD screen display enables easy operation
Memory includes running hours, die height, speed, pitch, feed-height and so on
Auto adjustment of press parameter and slide position to save time while mounting tools and setting on press
Temperature, air & oil pressure, motor current and so on are all displayed on screen
All operations are recorded in the system memory

All Models exceed the JIS Class “Special” precision standards and incorporate features like Plungers & Post Guides in hydro-static guide bushes, dynamic balancer, motorized slide adjustment with readout and interlocked hydraulic locking, closed-loop lubrication system with filtering and chilling, microprocessor controls with touch screen programming, feedback, fault indication and built-in interfacing with tool / process monitors and auxiliary equipments.

All presses are supplied as fully integrated lines with stock handling, High Speed feeders, Die Monitors, Die change systems etc.
