Tube Grinder Press brake May differ from the illustration Hydraulic cylinder with torsion rod Using the GB 28 Press brake, the desired bending angle to be produced can be programmed. The back stop position can be electrically adjusted from the front. The position of the back stop can be read off the adjustment wheel at the front. The adjustment wheel can also be used to make ne manual adjustments. • • • • • • • • User-friendly Small external dimensions Lightweight Adjustable bending angle Electrically-driven back stop which is adjustable from the front PROMECAM tool system from AMADA Low noise...

Stroke speed Through their easy-to-operate numerical control systems, the GB 30 NC series hydraulic press brakes offer perfect operating comfort. The control system supports single or repeated bending modes, which both can be run either manually or automatically. For repeated bending operations, 10 bending angles and 10 back stop positions can be programmed. The programs can be stored in 4 x 99 memory locations. • • • • • • • • User-friendly Small external dimensions Lightweight 10 programmable bending sequences Programmable back stop PROMECAM tool system from AMADA Low noise level Bending capacities...

Using a low speed when grinding stainless steel prevents it from tarnishing. Bluish discolouration cannot be completely prevented. The illustration shows a double exhaust system. We recommend this to our customers because grinding causes a lot of metallic dust. As costs are often an important factor, we have decided to provide this exhaust as a special offer. Changing the belt by releasing 2 quick-clamping screws. Rotary bender Our tip: You can achieve the best results with minimal reworking by using our special high-speed sanding belt, which is made of aluminia zirconia with multi-connection...

Bending rollers Digital display (optional control system) Feet for horizontal working position Cylinder up/down 20 bending positions can be stored. 10 programs with 10 bending positions can be stored. By repetitive operating of the hydraulic feed, the individual bending positions are successively positioned. The bending parameters for setting up the roller positions at a predetermined radius can be entered for 10 proles. Emergency stop Adjusting the stroke using the digital display. The end position is set using the mechanical end stop. With this controller it is possible to programme successive...

Press brake Prole bender Tube Grinder Mandrel bender Rotary bender The standard ttings of the machine include straightening rollers on both sides, with dual hydraulic adjustment. Each straightening roller can be positioned to provide the optimum correction required for the proles. The geometry of the machine makes it possible to bend large, heavy proles, as well as small proles with very small radii. Its characteristics make this the ideal machine for craftwork and industry. The outstanding feature is the ability to use independent reinforcement bars (patented), in order to increase the maximum...
