An arc and circle rolling machine is a machine used to roll metal into arcs and circles. There are many types of arc and circle rolling machines. The most common ones include the following:
Manual Arc and Circle Rolling Machine
Generally, these machines are operated manually using a crank handle. The operator has to turn the handle, which moves the rolling pins that curve the metal into arcs and circles. One good thing about these machines is that they are affordable. Again, they are ideal for low-volume production. On the downside, the rolling machine requires more physical skills and time to operate.
Hydraulic Arc and Circle Rolling Machine
This machine uses hydraulics to roll metal into arcs and circles. It usually operates by the combination of hydraulic power and rolling cylinders. The power of the rolling machine enables it to handle thick and heavy materials with ease. In addition to that, it offers a smooth and consistent rolling process compared to the manual machines. This includes less physical effort and skill. It is also ideal for more massive and thicker materials. Unfortunately, the downside of the hydraulic arc and circle rolling machine is that it tends to be more expensive compared to the manual version.
Electric Arc and Circle Rolling Machine
As the name suggests, electric arc and circle rolling machines are powered by electric motors. This gives them the power to curve materials of different thicknesses and sizes with ease. Thanks to its digital controls and automatic features, the precision and accuracy of rolling are improved. Unfortunately, because of its advanced features, the electric arc and circle rolling machine has a high cost.
The specifications of arc and circle rolling machines can vary based on the type and model.
Material capacity
Arc rolling machines usually indicate the thickness and width of the materials that can be used. For instance, an R-3*10mm machine can roll three pieces of steel with a thickness of up to 10mm.
Cylinder diameter
One has to look at the diameter of the finished cylinder that the machine can achieve. Different machines are designed to roll cylinders of various diameters.
Power source
Arc rolling machines are powered by electric motors, hydraulic systems, or a combination of both. The power source determines the torque and control of the machine.
Advanced accessories
Some arc rolling machines are equipped with advanced accessories or can be customized to be equipped with, such as a digital protractor for accuracy, CNC control for automation, or a hydraulic drive for smooth operation.
When one gets an arc rolling machine, they should know that these machines need to be well cared for if they are to continue giving great service and remain in excellent condition. One of the best ways to ensure this is by performing regular inspections and promptly identifying and fixing any issues. One should also ensure that the machine is adequately lubricated, and this can be done by checking the hydraulic and lubrication systems. Cleaning the machine should also be part of the maintenance plan. One can do this by removing any residue or debris from the previous operation. Finally, investing in operator training is a great way to ensure the machine is correctly handled, and its life is prolonged.
Operators and business buyers can use the arc and circle rolling machine in different industries and applications. Here are some of the most common scenarios of using a circle rolling machine:
Metal Fabrication Workshops
Many metal fabrication workshops use the circle rolling machine to bend metal sheets and pipes into arcs and circles for different structures. These workshops could be with or without CNC machines.
Architectural Design and Construction
The circle rolling machine is great for creating architectural features, frameworks, and domes in an easy and cost-effective way. Architectural designers can use the machine to roll different kinds of materials to get the desired shapes. In the same way, construction teams can use it to easily install the rolled materials of various sizes.
Frameworks For Cisterns and Tanks
Arc or circular frameworks are often needed to build tanks and cisterns. The circle rolling machine can roll the required arcs or circles with materials of different thicknesses. It is easy to make flanged circular frames and elliptical frames with the machine.
Support Frames for Pipes
Support frames for pipes are usually circular or semi-circular. A circle rolling machine can bend the support frames precisely so that it can carry the pipes properly.
Furniture Production
Circle rolling machines can make different types of furniture quickly at low costs. The machines are used to produce modern and fashionable furniture with arcs and circles.
Signage and Display Manufacturing
The combination of the rolling machine and CNC technology has largely simplified the process of making signage and displays. Circle rolling machines can easily produce the required materials with different thicknesses.
When buying a rolling machine for circles and arcs, one must look at various features and make a comprehensive comparison of the machine options to ensure the most suitable choice. Look at the rolling machine's construction, including the build material—those with steel constructions have longer lifespans.
Another thing to consider is the rolling capacity—the maximum width and thickness of the workpieces. Determine the nature of the workpieces and select a machine that can handle them. For large workpieces, universal rolling machines with a maximum rolling width equal to 2x the center length are ideal.
Investigate if the machine is suitable for the material's yield strength. For harder materials such as steel, an oil-hydraulic rolling machine ARC will work well. When dealing with high-strength or large workpieces, a pre-bending feature is necessary to avoid slipping. Look for a machine with a backroll that adjusts the workpiece's leading edge.
Consider whether a digital display that pays attention to the set temperature and torque will add operational convenience and safety when operating the rolling machine. A cone rolling machine can produce cones with varying angles by adjusting the position of the lateral rolls.
Learners and semi-skilled operators will find an easy-to-operate machine with manual or automatic controls. Highly skilled operators can handle versatile, high-precision machines with greater adjustment. Explore machines with various energy-saving modes.
Determine the machine's weight, including all the additional workpieces, when considering transportation costs. Forklifts and cranes can easily handle heavier weights. Check the rolling speed and power output, which can vary from 3 to 15.) Consider the operating voltage, which can range between 220V and 440V.
Q: What materials can an arc and circle rolling machine roll?
A: The machines are primarily designed to roll metal sections. However, heavy-duty machines can roll other materials, such as plastics, wood, and composites, provided they are not too thick and won’t break or get damaged.
Q: Can an arc and circle rolling machine roll metal with a variable thickness?
A: No. The rolling machine cannot roll metal with variable thickness. It can only roll metal with a uniform thickness.
Q: Can an arc and circle rolling machine roll metal with holes or slots?
A: No. The machine cannot roll metal with holes or slots. It can only roll a solid metal.
Q: Can an arc and circle rolling machine create spirals and helical shapes?
A: No. The machine cannot create spirals or helical shapes. It can only make arcs and circles. Separate machines are used to create such shapes.
