ABOUT TURRET PUNCH PRESS MACHINE
A turret punch press machine is a machine in which a large number of tools having different shapes
are arranged in a disk-shaped or fan-shaped turret, NC-controlled table and clamp holding andmoving a work (workpiece) are performs punching and forming into place.
NAMES AND FUNCTIONS OF MAIN PARTS OF THE TURRET PUNCH PRESS MACHINE① UPPER TURRET / LOWER TURRETToolholders which several tooling are set on.
A large number of tools can be mounted, and the turret of these tools is rotated and moved byNC-control and selected.
Misalignment of the upper and lower turret center leads to productfailure / tool breakage.We recommend that you perform maintenancewith a centering fixture etc. regular basis.

② STRIKER

A slide part that moves up and down with the force of a crank, hydraulic force or servomotor, and transmits
the driving force of the press to the tool.Push down the punch (upper) downwards by moving up and down.

③ CLAMPThe part that holds the material. The specified position of thework is moved to the base of the tool by NC control.

Press④ TURRET KEY② Striker

Positioning the angular shaped tool in the rotational direction.
Wear of the turret key leads to core misalignment of the tooland phase shift, which may cause machining failure and damage
to the tool.
We recommend that you perform maintenance on a regular basis.

ABOUT TURRET PUNCH PRESS MACHINE⑤ LIFTERS

Hold the upper tooling and put it up after punching.

⑥ DIE HOLDER

To be set die on Lower Turret.

Contamination such as slug and powdery dust may be mixed in the die holder.
Contamination of foreign matter leads to tool installation failure and can also cause tool
breakage. Be sure to do cleaning when set up the die.
In addition, by attaching a brush die or a roller die to a holder which is not used,
it is possible to prevent contamination and prevent scratches on the back side of the work.
FEATUER OF TURRET PUNCH PRESS■ Unlike a press machine, the machining position of the tool and material installed in the turretcan be controlled by program, and it can be processed with any tool.
For this reason, different products do not need to be changed or can be done in a short time.

■ Although the products are different, it allows to use same tool as long as hole or forming

dimensions are same.
■ It is also possible to produce various types of small quantities in combination with automatic
material supply, take-out device, automatic tool changing.

DRIVING METHOD OF TURRET PUNCH PRESSMECHANICAL PRESS (CRANK PRESS)
A system in which the striker is operated bychanging the rotational force of the flywheel
to a vertical motion via the crankshaft and thecrank.
[ Mechanism of Crank Press ]HYDRAULIC PRESS
A system in which a piston is moved up and down bya hydraulic pump to operate a striker.

1. Bottom dead point is adjustableby Machine program.
2. Top dead point is also adjustableby machine program which allows
to process at high speed.
3. Less noise comparing to CrankpressStrikerStriker

SERVO PRESS
A method of operating the striker by converting the rotational force of the servomotor directly or indirectly
to vertical movement via a crank.
