CNC Press Brake Machine

Salient Features
Technical Detail

The stable robust welded steel Frame made of ultrasonically and Tensile cested IS 2062 plate as per guidelines of IMTMA standards.
Fast approach & fast return speed to save cycle time, slow pressing speed for better stroke control & bending accuracy, ensures high productivity
Repeatability for ram position +0.05mm
Compact cylinders & low pressure system due to rear cylinders. Also it gives better rigidity & load carrying capacity against fatigue failure
Positive synchronisatio of cliders with welded torque tube gives better bending accurancy on both ends
Moving work station with manual, single cycle & automatic mode for easy operation with emergency stop button
NC upgradation passible on site
All electrical & hydraulic component from reputed make
Hydraulic cylinders made from seamiess honed tube, hardened & grounded chrome plated piston rod fitted with twin type zero leak PU seals
Suitable for upgradation with special optional features

Air Bending :
In air bending the dies are made at more of an acute angle (85' or less than the angle to be formed.The only contact between the dies and the material occurs at the male punch and edge of the female die.The material is ''Air'' bend rather than ''Coined'' od ''Bottom'' bend.

The advisable ''Vee'' openings for air bending are:
V= 6 to 8 x Material Thickness (t),When t < 4 KxLxSxt2
V= 8 to 12 x Material Thickness (t),When t > 4

Load, P = KxLxSxt2 \ 1000xV MT
