CNC Hydraulic Sheet Metal Press Brake Bending & Shearing Machine

600 ton CNC press brake machine is a heavy model of such kind machine,it is often use in some big projects, such as shipping,auto making and so on. For 600 ton press brake , the stability of frame is extremely important to the quality, to ensure the machine can be used for long time,the machine frame is integrated processed by large boring-milling machine, and also will be treated by the annealing furnace to eliminate the stress. Meanwhile, to improve the performance further, all the key machine parts we all adopt world famous brand, the electrical motor is from SIMENS Germany, the electrical components are from Schneider France,oil pump is SUNNY from USA, the valve is REXROTH BOSCH from Germany, the CNC control system is DELEM from Holland, ball screw and liner guide is HIWIN from Taiwan, China. Because we have taken so many effective measures to ensure the quality, we have got many quality certifications so far, which are issued by world famous certification authorities,such ...

500 Ton press brake   is a primary size in big tonnage machine. Under this tonnage, the standard length of work table start from 4000mm to 8000mm. If clients have special requirements, some customized size can be redesigned ------ this is the advantage and skill service of GLDMA.   Application fields of this size include bridge construction, public facilities producing, big storage racks manufacturing, also some small boat processing. 500T/8000mm can bend max 8mm/8000mm size, and 500T/4000mm can reach max 15mm/4000mm bending capability. We usually suggest client to choose CNC type on large tonnage machine, to ensure the bending effect and quality. The max opening height (daylight) can reach 600mm, and throat depth is 500mm. These parameters are both decided by the pressure and structure designed. During the producing of  large size plate bending machine , most important is the whole structure processing. GLDMA brought four big floor-type milling/boring facilities thi...

GLDMA 200 ton CNC hydraulic metal plate press brake machine is divided into four sizes of work table: 3200mm, 4000mm, 5000mm, and 6000mm length. A few clients ask that they want to have a 2500mm length, but this is not our standard size, in view of this length can not support 200 Ton pressure in long term, and it will influence the life span of machine. 200 ton is a middle size in press brake machinery, so the manufacturers of building structure, automobile small spare parts, even some small machine manufacturers will need this size. Delem CNC controller series is much more popular with customers.  CNC type  at least will be equipped with 3+1 axis, which bring the machine into a higher level of precision. Two cylinders are controlled by grating ruler, it will bring perfect performance on synchronization. What's more, the speed of two Y axis is obviously improved. This is why CNC press brake machine is much more expensive on price. About the configuration, we choose some...

This machine has high labor productivity and high working precision for bending metal sheet, and adopts different shapes of upper and lower mould Can be bent into various shapes artifacts, stroke at a time can be to a bending forming of sheet metal, after a lot of bending can obtain more complex in the shape of the workpiece when equipped with the corresponding equipment, can also make a punch. Different choices of 100ton press brake: 100ton/2500mm press brake bending machine 100ton/3200mm hydraulic bending machine 100ton/3100mm hydraulic bending machine 100ton/4000mm hydraulic bending machine 100ton/6000mm plate bending machine 100 Ton Hydraulic Press Brake Specification Type 100T/2500 100T/3200 100T/4000 Nominal Force KN 1000 1000 1000 Worktable Length mm 2500 3200 4000 Poles Distance mm 2020 2600 3000 Throat Depth mm 320 320 320 Slider Travel mm 150 150 150 Max Open mm 350 400 400 P...

GLDMA 80 Ton hydraulic bending machine is a very popular model, It is widely used in many small industry fields, especially for the thin plate, normally for stainless steel no more than 2 mm, for carbon steel no more than 4 mm, such as kitchen equipment, small piece process for other equipment. now, the 80 Ton press brake has 3 different length of worktable, 2500mm , 3200mm and 4000mm . As a professional manufacturer, we always put the safety of worker first, we put the laser guider protection on the two sides of the worktable to protect the worker from accident injury,  also we put light curtain on the back of machine.  The 80 tons bending machine with excellent performance, our standard throat depth is 320mm, the ram stroke is 100 mm and the max opening height is 350 mm, but if you need to bend larger plate, we can increase these parameter, the work piece linearity accuracy can be 0. 5mm/m, the back gauge accuracy can be 0. 05mm/m.  Meanwhile, for better perf...

40 Ton plate bending machine  just like baby in the press brake family. Usually with 1600mm, 2500mm length work table. These are popular size through customers. GLDMA 40 Ton press brake is with heavy welded frame, so that it has extremely good rigidity. Whole structure is processed entirely all together to guarantee high precision.  Considering it's pressure, the machine can bend max 2mm* 2500mm, 3mm*1600mm, common metal sheet (stainless can be 1mm*2500mm, 1.5mm*1600mm).  Of course, it the plate is not long, the thickness can be relatively thicker. So  40T hydraulic press brake  is widely used in some small parts fabrication, like door& window-frame fabrication, kitchenware processing, small electric boxes making, tiny accessory on automobile producing and so on. GLDMA NC hydraulic  sheet metal press brake machine  is equipped with Estun E21 control system, which is simple to operate, high performing, and cost-effective. Clients also can upgrade ...

The 30 ton press brake is a wise choice for small enterprise. As the development of world, more and more country have some small enterprise who take part in industry area. As metal play an important role in so many different industries, press brake also become more and more important. So for those small enterprises, we GLDMA design 30 ton press brake. Economichyd The  small size press brake  like 30 ton will not be a heavy burden to small enterprise. It can be a best choice when some company want to enter the metal process field. Besides, it will bring you profit soon if you have enough order. Quality Compare to big machine,  30 ton press brake  still have same high quality. The design of this servo press brake compliance with EU international standards.
