Answer You - Angle Roll Bending Machine Information for Buyers
There are two kinds of customer service we all experience occasionally, outstanding customer service, and bad customer service. What we experience most of the time is mediocre customer service.Mediocre is a strong word for average. That’s where your experience as a customer is not memorable, nothing special - under-whelming might be a good word!The problem with mediocre service is that it doesn’t give you a competitive edge. You simply compete with all the other businesses like yours who keep undercutting each other on price and quality to stay in business.I asked a group at one of my seminars to write down the name of places they’d gone to do business that they considered outstanding, and then we discussed why they considered them outstanding. Nobody came up with more than one name, and some couldn’t think of even one business that they considered ou
When a section dimension and thickness is not mentioned on the capacity charts, the user either needs to calculate the section modulus of the section and if this is less than the Section modulus capacity of the machine, he/ she will be in the safe zone and no damage will come to the machine. If in doubt it would behoove the user to contact the manufacturer for professional advice.
Controls:
Section bending machines have become sophisticated and are using NC and CNC to bend complicated forms. These controls have canned programs for standard sections and they use teach mode where by the operator can produce the part manually and the machine keeps track of all the steps he/ she uses to accomplish the job. Then the program is memorized and archived for continuous use.

You can choose Your careerAre you one of the many people who don't feel pleasant with your current job or career? Have you worked in one career for many years, and found yourself burned out? Or do you feel that your life is not what it could be, because you can't take out your full potential in the job or career you are in? Changing careers and jobs is indeed an issue that concerns many of us. What's really amazing me is the fact that many people - myself included - are continuing in the same job or career year after year, even though they are sick and tired of it and really want to quit their jobs and start up with something else. I think this grounding is a part of human nature: it's a comfort zone that is difficult to climb out of, using arguments as "I know the job I have, but not which job I'll get."Before I finally took the step that I had
If you have ever seen an angle roll bending machine, you would agree that most are constructed in a vertical steel frame. It is common that the bending portion of the machine is located on one side, with the power and drive of the machine on the opposite side.
This writing is intended to educate and help the purchaser of Angle Bending Machines to ask the right questions when considering a purchase.
Power source:
Small units are powered by an electric motor with a reducer. The power transmission is accomplished by gear trains and or chains / sprockets combinations. These are units used in small job shops and rod iron fabricating establishments. The new generation of the section bending machines is powered by hydraulic systems. These are used for bending from the smallest bars to very large wide flanged structural beams.
The large hydraulic units have a double pump hydraulic system, with one providing the flow for the rotation of the rolls and the other for the extension and retraction of hydraulic cylinders attached to arms carrying the bending rolls.
Some designs use one main hydraulic motor, usually mounted to an epicyclical in-line reduction gear, which imparts rotation to all three rolls. Another variation is each roll having its individual hydraulic motor/ reduction box combination directly driving it.
The Bending Process:
There are some terms used in the industry describing the capacities of Section Bending Machines and the process used, which the purchaser should become familiar with.
Square and rectangular rods, round rods, square and rectangular tubing, round tubing, standard pipe, equal leg and unequal leg angles, "C" and "MC" channel, "S" and "WF" beams, "T" bars …these are sections which can be rolled on section bending machines.
"Leg out" means the leg of a section, like in angles will stick outward from the ring formed in a radial direction. "Leg in" means the leg of a section, like in angles will stick inward from the ring formed in a radial direction toward the center of the ring. "Leg out" is also known as "Easy way" and "Leg in "Hard way" There are exceptions to this terminology when it comes to channels, whereby one can bend a channel leg in, leg out and the hard way when bent on its side.
Bending of round sections, pipes and round tubing require special tooling other than what is usually provided standard with section bending machines. In special cases with square and rectangular tubing where the wall thickness is low…the manufacturer should be consulted as to whether special all section enveloping tooling is required to avoid the section from collapsing under the bending forces.
Bending Channels, S beams and WF beams the hard way, present a special challenge because the force of bending would sometimes collapse the web connecting the flanges. Most manufacturers of heavy section bending machines offer what is called a "Traction Tool", which holds the section back and supports the web so as to avoid collapse.
Machine Capacity:
Each section has what is known as a "Section Modulus". This value is a measure of the resistance a section displays to bending. It is the quotient of the sections Moment of Inertia about the axis passing through its center of gravity, which coincides with the neutral axis of the section and the furthest distance on the section from that neutral axis. In symmetric sections bending about the neutral axis both ways will give the same section modulus, however in non symmetric sections, the section moduli are different for calculations of leg in and leg out bending.
Depending on the design of the machine, each machine will have a certain capacity of bending. Thus the pressure exerted on the machine members will dictate the limit, before rendering the deflections the members sustain unacceptable or the wear and tear caused on the machine would be excessive. This limit is what is specified as W or S (Section Modulus Capacity) in in3 or cm3.
In general catalogs and brochures describing section bending machines would give the maximum section sizes a machine can bend of each type of structural or bar section. With a minimum diameter the machine can bend them to. By rule of thumb and practice it has been established that the minimum diameter of bars, tubes and pipes is ten times the height of the leg or the dimension taken in the radial direction. For the rest of the sections it is approximately 11 to 12 times the height of the section or the leg.
When a section dimension and thickness is not mentioned on the capacity charts, the user either needs to calculate the section modulus of the section and if this is less than the Section modulus capacity of the machine, he/ she will be in the safe zone and no damage will come to the machine. If in doubt it would behoove the user to contact the manufacturer for professional advice.

Many practitioners of business opportunities, which sell small business models to consumers, are excited to see that they will soon have a separate category of law, rules and regulations at the Federal Trade Commission. Most all Franchisors, those who sell franchises are also ecstatic over the move and say it is about time.Here is an excerpt from the Federal Trade Commission’s report of all the commenters on this proposed rule change and separation of the two business models;“Based upon its enforcement experience and the record developed to date, the Commission has determined to promulgate a separate trade regulation rule to address widespread fraud in the sale of business opportunities. This approach is consistent with the view of the vast majority of commenters and the regulatory approaches adopted in most states.”“Further, unlike most franchises, m

Business brokers help you in the sale and purchase of businesses. They charge fees for providing brokerage services. The fees depend on the size of the business, the final sale and the purchase price. There are different business brokers for dealing with different kind of businesses. For example, some of them might specialize in mergers, and others in acquisitions. Apart from the fixed fee, most of the brokers also charge commissions. The commission can be computed on the basis of the selling or purchase price of the business. The larger the price, the greater the leverage to negotiate commission rates with a business broker.If you have sold your business or purchased a new one you might feel you don’t need the help of a business broker, especially if you know the prospective seller or buyer well. But if you are entering a new industry, buying or selling a big busi

The Franchising Industry has taken some hits in the last couple of decades. Some came from onerous regulation and piss poor performance of agencies like the Federal Trade Commission’s Consumer Protection Division’s Franchise Group where some believe Steve Toporoff had done so much damage to the industry that he should resign in disgrace and lose his pension. Yet others applauded this gentleman’s efforts for working with industry and lawyers to develop laws, which would keep the FTC in a referee position. Personally, I believe the former opinion is more appropriate and realize in hindsight that the damage that the FTC did under his leadership in the Franchise Group of the FTC led to the failure of some 4000-franchise companies between 1985 and 2001.The Federal Trade Commission now has not prosecuted or attempted to prosecute a franchise case since 2000 that I am awa

This may seem like a rhetorical question, but stop and think about your business ― from your CUSTOMER's perspective, ask yourself: Is your organization truly easy to do business with?I recently called a local auto dealer to schedule routine maintenance on my car. I spoke with the Service Manager who was very nice. He was very efficient, in fact too efficient. He hung up on me while I was in the process of asking to speak with a salesperson.I've always liked the dealership so I called back. The Service Manager answered the phone. I told him that we'd just spoken and that he had hung up on me! I assured him I didn't think it was intentional, but that he was merely in a hurry. I also explained that I wanted to speak with a salesperson.He apologized, thanked me and hung up – again! I called back a third time and a salesperson answered the phone (tha

Then the program is memorized and archived for continuous use.
The new controls can even collect their own section characteristic data, by bending a piece of the section at different settings. The radius produced at a certain setting is input into the program and by taking three readings, the program surmises the reaction of the section to bending forces; then uses the information when the program parameters are entered and the part is run…at first trial the machine would produce a near perfect part. With small adjustments, what used to take hours of testing, experimenting and developing is cut down drastically.
Controllers have large memory capacity and many job programs are stored and recalled easily. Most units have RS232 communication capability and lately USB ports have been appearing on most of them. There are many operating systems used on these controllers…some are still using DOS, some use Windows and even Linux, while some have proprietary operating systems.
Observation:
With each passing day, technology is improving, and this is no different for angle roll bending machines. Computers and engineers are largely responsible for section bending machine construction, and this allows for more precise equipment. Some inexperienced shoppers may jump at a machine with greater horsepower or even one that weighs more. Do not be fooled; instead consider these things when buying: reliability and durability of materials used in the machine's construction, solid design, and of course ease of maintenance.
