The stationary punching machine has been developed for control cabinet

and switchgear manufacturers, for quick punching of round, square, rectan-

gular or special forms in sheets and control cabinet doors up to 2200 mmx

1000 mm and 40 mm folding height. Punching is possible up to the edge

area. Easily executable tool exchange, quickly in a matter of seconds even

with a mounted door. Stop system movable in X and Y-direction.

Description:

n Stable pressing body in robust, deformation-rigid welding construction

mounted on stationary frame with rubber-bonded metal feet.

n Swivel control desk with digital display, emergency off button, electric

operating buttons and two-hand operation.

n Double-acting hydraulic cylinder, ﬂanged on machine body via force and

positive connection.

n Non-rotationally arranged piston rod Ø 63 mm, made of hardened and

tempered stainless steel with tool holder.

n Die seat, frictionally connected with the pressing body.

n Time relay for the return of the piston spares working time.

n Down-holder/stripper combination with ﬁnger protection.

n X-Y stop system, easily movable in robust and precise proﬁle roller guides.

n Positive and frictional workpiece support and clamping device.

n Swivelling workpiece support on the left of pressing body for easy lifting

of the workpiece.

n Stop system locking via electrically operated hydraulic brakes.

n Digital distance measurement and display of the X- and Y-traverse paths

with a display accuracy of 0.1 mm and a measuring accuracy of 1 ‰.

n Quick tool exchange helps in case of problems with many through-hole

variants.

n Two-circuit hydraulic unit with electric pump, oil container and magnetic

valves, very quiet.

n Tip: Using laser pointer as option for optical indication of tool centre.
