The Pros and Cons of CutOff Machine Types

 

When you want to process a large batch of metal tubes in a single run, there are various ways of getting the job done.  Of course, metal tubes can still be cut by hand, but this is a time-consuming and laborious process, and most manufacturers have now turned to automation to get their large batches delivered quickly.  These manufacturers have the option of choosing from several different types of cut-off machines, each with their own set of “pros” and “cons.” 

The basic division between types of tube cutting machines are the movement of the head:  stationary or rotating.

Stationary Head Cutting Machines

A stationary head cutting machine does exactly what the name implies:  holds the cutting head stationary while the tubes move into position, either by being manipulated by hand or by a machine.  The cutoff process centers around this stationary cutting head, so moving the tubes into position becomes the focus of the process. 

The benefits of this type of setup include low-cost and ease of use for small runs.  However, there are also several disadvantages to a stationary head cutting setup.  For one thing, the movement of the tubes often results in chips or snags at the cutting edge, which can lead to damage to the tubes or injury to workers.  Further, most stationary-cut tubes require a second milling process for chamfering or shaping; this may require transporting the tubes to a different location, adding a step to the labor process as well as the purchase of two machines instead of one.  Finally, many stationary head cutting machines are incapable of cutting varied shapes and are limited in the range of tube sizes they can accommodate.

Rotating Head Cut Off Machines

A rotating head cutoff machine uses a completely different mechanism for handling metal tubes.  Unlike the stationary head cut off machine, where the tubes are fed in by hand, the rotating head machine moves the cutting mechanism around the tube, which is held stationary during the process.

This type of tube cutting and chamfering process has many advantages.  First, it allows for much finer and more precise cuts than a stationary cutting saw can provide.  The tube being held stationary allows a servo-controlled rotating head to swiftly make custom cuts and shapes that are simply not possible on a stationary head.  Furthermore, the rotating head means that the tube is cut while being held still, leading to far less kerf waste and burring.  When a tube is cut using a rotating head, the precision of the cut allows the operator to control, to a large degree, the slips that often cause burring or chipping.  This makes the cuts safter for workers to handle.  Finally, a rotating-head machine can often handle much larger loads than a stationary machine, and make multiple cut lengths at once, shortening the processing time. Because the cuts and chamfering are all done in one spot, this also cuts down on labor in processing metal tubes.

Machinery Options for Workforce Safety

Image
One thing that gets plenty of attention in the industrial world is worker safety.   Skyrocketing costs for medical care and workers’ compensation insurance have prompted studies into how to improve worker safety.   Many company owners also simply want to do the right thing and protect their workers from mishaps on the job.   Because of this, more and more industrial business owners are considering ways to make their workplaces safer for themselves and the people who work for them. This is where installing an Automatic Tube CutOff Machine can transform a workplace from unsafe to safe and productive.   By investing in a machine that automatically loads, handles and unloads metal tubes, owners of businesses that specialize in cutting tubes can make their workplaces safer and more productive.   How A Rotating-Head Cutoff System Makes Your Workplace Safer   Increased safety in an industrial workplace is often a product of reducing contact with material.   The fewer times workers have

How To Streamline Production of Metal Tubes

Image
  Investing in a rotating head cut off machine is one way to streamline the production of metal tubes at your plant.   A Rotating Head Cutoff Machine can greatly increase the efficiency of tube cutting and chamfering as well as loading and unloading, saving your plant time and money.   However, a machine only works as well as the overall system you have in place to minimize disruptions and maximize output.   How can you truly streamline your processes and increase profitability at your plant?   One way may be to look at the software you are using to monitor your overall production methods.   There are certain types of systems, such as an MES system, that can exponentially increase production, monitor safety issues, and make your plant much more efficient. How Software Streamlines Production One type of software known as MES, or Manufacturing Execution System software, is designed to oversee production of metal tubes from start to finish.   Not only does MES control the loading, cu

How the Hautau SC30 Tube Shear Cut-Off Machine Increases Productivity

Image
There are many options on the market for any company considering investing in a tube beveling and chamfering machine.   If you are in the market for an automatic tube cut off machine, and you need a system that can handle carbon or HSLA tubing up to three inches in diameter, the Hautau SC30 can offer you a superior process that can include automatic deburring and chamfering as well as other end-finishing processes. How Does The SC30 Handle High-Speed Tube Cutoff? Almost any traditional lathe machine can cut metal tubes.   The problem is that many machines are simply not built to withstand the intense vibration and movement that occur with traditional lathe processes, and this shows up in the final product.   Vibration, over-rotation and movement during cutting can produce ends that are chipped, imprecise or even destroyed. With the Hautau SC30 tube shear cut-off machine, high-speed tube cutoff, even for larger tubes of 3 inches in diameter, becomes simple and produces profession
