Tandem Press Brake

Tandem Press Brake Machine with 3-4 Axis

The tandem press brake system facilitates the concurrent of two machines, commonly employed in the manufacture of large workpieces such as light poles, communication and power towers, and construction machinery. In comparison to large individual machines, it offers simpler installation and faster production times, rendering it a superior option for companies with output value demands.

Switch between tandem or single mode operation at any time, and transfer bending programs between presses. All working modes comply with the strictest CE standards.

KRRASS’s tandem press brake advantages allow you to save time and achieve greater efficiency than bending with smaller machines.

Introduction to Configuration

FEA & Stress Analysis

Stress Analysis & Finite Element Analysis

The CAE software SOLIDWORKS used as the method to analyze the linear static construction, stress and deformation for press break and laser cutting machine frames. So for complicated structures, highly complex loading’s, transient modelling and combination of the above, FEA makes sense.

Manual Upper Tool Clamping

The CNC Press Brake Machine use all Raw material is provided by qualified suppliers and chemical composition corresponds to international standards. Therefore, raw material yield and tensile strength are guaranteed, are standardized with a 8.4 x 3.5 mm safety groove, which keeps the tool from falling out.

Advantage:

Safe and fast tool change
Can be used without modifying Europe type punches
Front clamp – vertical tool change
Rear clamp – horizontal tool change

KRRASS® BGA-4 BackGauge

Proportional Valve

The German Rexroth fully closed-loop electro-hydraulic servo high-frequency synchronous control system is adopted to ensure that the machine tool has high stability and high precision in the process of high-speed operation.

Advantage:

The frequency response (response frequency) is higher and can be as high as 200Hz.
It can continuously and proportionally control the pressure and flow of the hydraulic system, control the position, speed, and force, and reduce the impact of pressure changes.
Closed-loop control, signal feedback.
Original German imported products, longer service life.

Hybrid Servo ECO Function

KRRASS® New Hybrid Servo ECO Function (Optional)

KRRASS® promotes a friendly environmental policy, and as such all our equipment features the Hybrid ECO Function. Our hybrid servo-drive positioning system provides accuracy at any position.

Advantage:

Operating cost is min due to low energy consumption. Thus, it gives advantages to the user with high efficiency & low operation cost.
High dynamic for a higher productivity of the machine.
Compliance with EU Directives.
Lower energy for a green Machine.
Lowered sound pressure level at 50 dB.
The servo-motor, with closed loop speed control.
Energy efficiency of up to 35 % compared to conventional systems.

Punches & Dies

CNC Press Brake punches and dies will be one of the most important topics we discuss before you place the order. Any bending shape will be completed by a suitable set of punch and die. We can provide appropriate toolings according to different bending requirements of customers.
