Things to Check Before Buying a Used Amada RG-80 Press Brake

Amada RG-80 is a well known CNC brake press machine that is appreciated by machinists across the world. So, the machines are widely available in the used CNC machines market and have a huge demand among manufacturers. Fabrication shops that are looking for a reliable machine with good bending quality often look for this machine in the market. But when buying a used machine, one needs to do a proper inspection, or they might get scammed. So, here are things to check before buying a used Amada RG 80 press brake machine to make a reliable purchase.

What are the Major Things to Check Before Buying Used Amada RG80 Press Brake Machines?

Here are some of the major things to check when evaluating used Amada RG 80 press brake machine for your shop:

1. Overall Machine Structure and Frame Condition:

The first thing that should be on your used Amada RG80 inspection checklist is the overall machine structure and the frame condition. The machine faces regular mechanical stress during bending operations. So, when evaluating the frame, one should:

  • Look for signs of deformation around the high stress areas. 
  • Check if the ram appears aligned evenly across the bed. 
  • Inspect the bed and side frame of the machine for visible cracks or weld repairs. 

If the machine’s frame shows signs of distortion, the bending accuracy of the machine can be affected.

2. Ram and Bed Alignment:

One of the major things to check before buying a used Amada RG 80 is the ram and bed alignment. The alignment plays an important role in maintaining the accurate bending quality of the CNC machine. When doing the inspection, one needs to check whether the ram moves smoothly and evenly during operation. Here are the major things that one needs to observe:

  • Whether the machine shows uneven gaps at different points
  • Whether the bending angle changes across the part length
  • Whether the ram reaches the bed evenly across the entire length

If the ram and the bed are not properly aligned, then parts may bend differently from one side to another, so checking their alignment is important for Amada RG 80 bending accuracy checks.

3. Hydraulic System Condition:

The hydraulic system powers the ram movement in the Amada RG80 press brake machine. Proper functioning of the hydraulic system is essential for stable machining operations. Here are several components that should be examined:

  • Hydraulic pumps
  • Valves and seals
  • Hydraulic oil condition
  • Hydraulic cylinders

Make sure to check for leaks around fittings, hoses, and cylinders.

4. Backguage System Accuracy:

The Amada RG 80 backguage accuracy plays an important role in positioning sheet metal before bending. If the backguage does not move accurately then the operators may struggle to maintain consistent bend dimensions. When evaluating the backgauge:

  • Listen for unusual noises during the movement
  • Check the movement along the axis
  • Observe whether positioning is consistent during repeated machining cycles

There are some other things to check before buying a used Amada RG 80, like electrical component condition and the maintenance history of the machine. So, now if you are interested in buying a used Amada RG-80 press brake machine then check the collection of MachineStation.

Conclusion: 

Different fabrication shops often rely on the Amada RG 80 press brake machine, which has reliable qualities helping you to do bending work in the right way as per its capabilities. So one might go ahead with buying used models of these machines if they find the features attractive for their business.

FAQs:

1. What materials can be bent using an Amada RG-80?

The machine is commonly used for bending sheet metals such as mild steel, stainless steel, and aluminum. Material thickness capability depends on tooling setup and machine condition.

Like most hydraulic press brakes, the RG-80 requires routine inspection of hydraulic oil, seals, and pumps. Regular maintenance helps keep the hydraulic system functioning smoothly.

Backgauge accuracy affects the positioning of sheet metal before bending. Inconsistent positioning can lead to variations in part dimensions, which is why checking backgauge movement is important during inspection.
