The newly developed solid loop frame and the original Komatsu MAY PRESS motion have achieved high productivity and high precision presswork.

High rigidity solid loop frame of one-piece-thick-plate

Stress at full load has been reduced by 50 percent with the high rigidity solid loop frame to greatly extend machine life. Its durability will reach the next generation.

MAY PRESS link motion, the most suitable to forging

Komatsu's unique MAY PRESS link motion is extremely slow at forming area to achieve stable, high precision forming with a smooth plastic flow.

MAY PRESS link motion, the most suitable to forging

Most suitable to transfer forging

A wide transfer presswork range thanks to a large allowable eccentric load and wide feed pitch 3-train BKO

Most suitable to transfer forging

Device locations for easy maintenance

A flow meter is mounted for the operator on the floor to check lubrication to the drive. And positions that require daily check are put together for easier maintenance.

From KONSEI

We previously produced parts for air bags first by striking with a parts former and then by machining.
Since we are originally a good former producer, we switched to finish using L1C in different material, which reduced manufacturing costs. The machining line of 24 NC lathes has become unnecessary.

From Ogura Clutch Co., Ltd.

We introduced L1C for developing near-net-shape and other new manufacturing technologies.
We set up a tandem line with a transfer machine to newly develop a system for finishing forged rotor materials within the company. Eventually the line has been arranged to form both rings and thick plate.
