All-Electric Benders from BLM Drive Efficiency for JML Engineering Twenty years ago, Alistair Bailey became disillusioned with working long hours for the benefit of someone else’s business, so he made the break and created JML Engineering Ltd to specialise in tube bending and tubular fabrications. The business developed through investment in several used hydraulic tube bending machines, with key customers providing steady orders for security (bollards and crash protection) and safety (hand railings and cages) products. These old hydraulic machines served the business well, but as with all things, age started to tell and support for them from the manufacturers became non-existent. Recognising it was time to invest further in the business to improve productivity Alistair researched the market and identified that a switch from hydraulically operated benders to all- electric was the way to go, and this saw the arrival of his first BLM all-electric multi-stack tube bender, an Elect 52. “Breakdowns on our hydraulic machines were becoming an increasing issue and the decision to invest was made for us because of this. The arrival of the BLM Elect 52 certainly eased the demands being placed on production due to business growing rapidly and the Elect 52 handled the bending of smaller handrails with ease,” says Alistair Bailey. A key advantage of the BLM All-electric Elect machines is the speed at which they can be set-up and the guarantee that bends will be consistent, without any need for adjustment from the start of a batch to the last tube being finished. The CNC control on the Elect machines manages all of the clamping and slide pressures to ensure consistency of the bend, once the tools have been changed, the operator simply calls up the program and the control takes care of the bending process. “On our hydraulic machines, on which we were very well versed, it could 18 TUBE NEWS June 2019 take 45 minutes to achieve a first off, after which there would be a degree of trial and error before we got the bend just as we wanted it. Now, we can complete the set-up in less than 15 minutes and know that the first tube will be within specification. Scrap is a thing of the past thanks to the uniformity of the process and the software in the control is a major benefit. For example, the B-Tools software helps to eliminate the requirement for manual adjustments, which were always needed on our hydraulic machines.” B-Tools software is part of the standard VGP3D 3D graphic programming software contained within the BLM control and functions by taking theoretical data of a part to be bent and automatically applying corrections from a database of materials and bending experience. a correction from data stored a database of prior bending experience in similar materials. Overall the VGP3D programming software allows the user to either create a part program at
