MB8 CNC Automatic 3+1 Axis Hydraulic Sheet Metal Press Brake Bending Machine With DA56S System Introduction

1. The design meets EU international streamlined design. The fuselage eliminates internal stress by annealing and ensures higher precision and strength. All machines are designed using SOLID WORKS 3D programming to make worktable high rigidity and the whole work More scientific.
2. The MB8 series automatic sheet metal electro-hydraulic bending machines use CNC control system (Delem DA56s from Holland) to help you increase your productivity and keep the lowest cost and lower maintenance costs.High quality and repetitive bending is obtained by using synchronized cylinders and valves (Bosch Rexroth from Germany).
3. The latest high frequency response hydraulic control technology, high speed, high efficiency and high precision.
4. Rigid upper beam runs on 8-point bearings with bending precision of 0.01 mm.
5. Use fully closed-loop electro-hydraulic servo control technology, bilateral gratings can feedback slider position signals  to CNC system to control the two oil cylinders(Y1,Y2)  running on the same frequency and maintaining the workbench's parallel state.
As one of China's largest hydraulic press brake manufacturers, GILDE offers high quality automatic sheet metal bending machine for worldwide customers with excellent technical support and after-sales services.

Maintenance of Hydraulic Press Brake Machine

Regular checking is necessary during daily producing. Today let's talk about how to make basic maintenance of automatic sheet metal bending machine.

We can divide the press brake into four basic parts: hydraulic system, mechanical system, electrical system, and mold system. So the daily regular checking can start from these four areas. The procedures are usually quick and simple. 


There are five steps which can ensure bending machine in good bending performance, in the long term, also have significant on lifespan of press brake.

1. Have a look around of machine
This is the basic step, just like checking high speed train before a new travel. This visual inspection of all areas will make you to find out tiny issues before they become large troubles. Confirm that the press brake is in clean condition; verify the tooling(upper and lower dies) alignment and inspect the tooling's condition. Also inspect the proper operation of all devices, including the position of backgauge fingers, foot pedal control, and indication lights. Verifying that these devices are working normally takes only minutes.

2. Check the Hydraulic System Condition
Keep the hydraulic oil clean, and check the oil level in the tank periodically. This is a simple visual check that can easily be performed daily. Dirt dust may enter the hydraulic system because of insufficient sealing. Make sure the tank seals and airiness are in good condition. 

3. Verify the Mechanical Parts
Mechanical components are the physical foundation of plate bending machine, like piston bolts, chain belts, and guide ways—must be checked a minimum of twice a year. Regularly check the connection between the pistons and ram. Check all bolts and screws for tightness. Realign the backgauge and stoppers. Another important thing is that require lubrication in regular time.

4. Examine the Electrical System
Examine all connections on terminals, relays, and terminal boxes on motors.
Check all voltages coming from power supplies and transformers.
Check all cables and switches for damage or malfunction.
Check fans for operation.
Check operation of all machine functions and safety features.

5. Inspect the Molds
Molds are the assistant of plate bending. Keep tooling clean and free from mill scale, and perform a visual inspection of tooling every time before use. Tooling that is cracked or damaged in any way must be returned to the tooling manufacturer for evaluation, reconditioning, or replacement.
