– Standard, small and large, etc.

Different models have their own characteristics to meet different needs. Which ones are the most worth buying?

Below, we will recommend the 5 most popular and hot sale models in 2020.

Recommend model 1: Servo Hybrid Press Brake

With the deep awareness of energy conservation and environmental protection, energy-saving bending machine has attracted much attention. In 2020, the most popular energy-saving bending machine is CNC hybrid servo press brake for sheet metal.

Servo-Hybrid-Press-Brake

Features

Working principle:

– The main servo motor drives the oil pump.

– The numerical control system controls the flow and pressure of Y1 and Y2 cylinders respectively through two sets of servo bidirectional pump systems.

– Two sets of servo pump control systems respectively drive the oil from the upper chamber of the oil cylinder into the lower chamber directly through the oil pump to realize the lifting of the upper die.

– When the oil pump reverses, the oil in the lower chamber is directly driven into the upper chamber to realize the bending of the sheet metal.

– The left and right synchronization of the upper die is separately controlled by two sets of servo bidirectional pumps.

– When the bending machine is in standby or fast down, the servo main motor rotates slightly.

– When the slider enters the low speed state, the main motor runs normally.

– After unloading, the main servo motor enters the high-speed rotation state, and the slider returns back quickly.

Advantages:

In the past, the hydraulic bending machine was torsion shaft synchronous or valve controlled. CNC hybrid sheet metal press brake machine is a real servo pump controlled bending machine, not proportional valve controlled. The synchronization of the machine tool realizes the pump control.

– Environmental protection

No leakage, green and Eco-Friendly.

It runs super quietly, 20 dB only.

– Energy-saving

Save more than 80%-85% electricity.

Brand new appearance design, small floor space and space saving.

– High precision

The friction between the left and right cylinders and the synchronization of Y1 and Y2 are not required. Each servo motor controls an oil pump and an oil cylinder respectively to ensure the maximum accuracy of the slider.

Servo pump control ensures the stable hydraulic oil temperature for consistent bending accuracy.

– High efficient

Super high speed, up to 300mm/s without vibrate.

It is conducive to continuous operation for 24hx7days.

– High performance

The operation is more stable, more reliable and safer with low failure rate.

Stable oil temperature extends the using life of each part of the hydraulic system and greatly improves the user working environment.

Multi-axis available, even more than 6 axis. It can meet the processing of all common work pieces.

Advice

Recommend model 2: Electro-hydraulic Press Brake

This kind of press brake has been the highest sales volume on the market in recent years.

Generally, when it comes to CNC sheet metal press brake machine, we all first think of electro-hydraulic synchronous press brakes. Because the electro-hydraulic numerical control press brake machine is the most representative and the most popular model.

Electro-hydraulic-Press-Brake

Features

Working principle:

The electro-hydraulic synchronous CNC bending machine relies on the computer to control the synchronization of the machine tool through the electro-hydraulic proportional servo system.

The standard configuration is 4 + 1 axis:

– Y1 and Y2 axes control the values of oil cylinders on both sides.

Y1 controls the left cylinder and Y2 controls the right cylinder to ensure the synchronous movement of the slider.

– X axis controls the forward and backward movement of the back gauge.

– R axis controls the up and down movement of the back gauge.

– V is workbench compensation.

Multi-axis available: 4 axis, 5 axis, 6 axis, 7 axis, 8 axis.

Advantages:

Comfortable operation and modern technology will greatly improve the working efficiency.

– Hydraulic transmission, stable and reliable operation.

– Upward bending design. Low noise and stable working conditions.

– With double guide rail structure, the slider runs more smoothly.

Electro-hydraulic servo system, full closed loop feedback control synchronization.

– It can carry out eccentric load bending. Y1 and Y2 can be programmed separately and can work under unbalanced load.

– Equipped with an anti throat deformation system ensures bending accuracy.

– The bottom dead center has pressure holding time, which can be programmed to ensure the accuracy of different parts.

– With the function of slow return control, the operator can better control the work piece.

– It is an upgrade of the traditional hydraulic press brake. It has higher precision, faster speed and better operation than torsion shaft type.

Advice

Electro-hydraulic CNC press brake for sale is the most cost-effective model for all ordinary users.

In the sheet metal industry, all factories that need to use bending equipment can choose it!

– For users with high requirements for bending accuracy, there are hydraulic compensation and mechanical compensation, two configurations to choose from.

– If you want to process complex work piece, we suggest you choose multi axis model. 7-axis or 8-axis high-end series can process more complex work pieces.

Recommend model 3: High-speed Mini Press Brake

Although this high-speed press brake is small, its performance is very excellent. Mini high speed sheet metal press brake is very popular in Europe and North America.

High-speed-Mini-Press-Brake

Features

Working principle:

The standard electro-hydraulic CNC press brake has two oil cylinders. Mini press brake has only one cylinder. This is the most distinctive feature!

The design of single cylinder makes it compact in structure, small in volume and more suitable for the processing of small thin plate.

Servo control 4-axis with Mitsubishi control system

– The direction of slider travel (Y axis) and rear stop (X, R, Z axis) are controlled by CNC system.

– X-axis controls the forward and backward movement of the back gauge.

– R-axis controls the up and down movement of the back gauge.

– Z-axis two fingers controls the left and right movement of the back gauge.

Advantages:

High speed

– No load speed (Quick down): 150-400mm/s

– Working speed (Slow down): 5-20mm/s
