Newall Measurement Systems is pleased to announce the achievement of the ISO 9001:2015 Quality Management Systems Standard Certification. The transition to the new ISO 9001:2015 standard this June co...
As the name of their website www.largemachining.com implies, GEDICO International Inc./ Dayton, Ohio, are specialists in large part machining. GEDICO will make or repair large parts. They also reverse engineer and machine parts to replace machined or cast, outdated or unavailable, old or new parts for large equipment – often with no prints necessary. They specialize in the steel, aggregate, rail, coal, power generation, and governmental utility (including support of local water works) industries. As Don Smith, VP and Plant Manager puts it, “ we do jobs other guys can’t do, or won’t touch.”
Like many shops, GEDICO has come to rely on Digital Readouts (DRO’s) to provide accuracy and consistency of their work. Machining these large parts on the big machines they own can be challenging to a DRO system, and after years of using and maintaining other DRO brands, GEDICO found out about Newall. Don states “we don’t have exactly a hospital environment around here, and we were getting tired of cleaning and replacing glass scales on other systems. The reliability of Newall’s Spherosyn scales resolved that problem for us.”
There was one DRO challenge that, at first, GEDICO could not seem to find a solution for. Their largest capacity lathe, a Niles VTL, has a massive 144” x 120” capacity. Installing DRO linear scales on the X (cross travel) and Z (up and down) axes on most VTL’s is no problem. Installing a linear scale requires that of the 2 main components – the scale and the read head – one travels along with the moving axis, and the other stays stationary. However, on this Niles VTL, there was no obvious way to mount the Z (up and down) axes scale on the ram of the machine.
Don Smith called in Mike Kilroy of The Mike Kilroy Company to help find a solution.The Mike Kilroy Company provides synergistic technical sales and support of the state of the art motion control products they represent. Kilroy has represented and assisted in engineering in Newall linear encoders for motion control and DRO applications for several years. After a quick assessment of the Niles VTL, Kilroy asked Don Smith of GEDICO “is the ram of the machine hollow, or solid?” The ram in fact has a 3” cored hole through the center.
The unique design of the Newall Spherosyn linear scale allowed Kilroy to provide a solution, as pictured. The Spherosyn scale requires no backer bar, spar or machined surface. The only component requiring precision alignment is the read head, which slides over the .600” diameter scale (tube.) The scale requires no indication or flat surface. That means Newall Spherosyn scales can be mounted in much less time, almost half the time, of any other type of linear scale. Vertically mounted Spherosyn scales only have to be fixed at one end of the scale (tube.) This allows Newall Spherosyn and Microsyn linear scales to be mounted in places where no other linear scale can be mounted, and provided the solution for GEDICO (along with some intuitive thinking by The Kilroy Company,) enabling them to enjoy the DRO benefits on both axes of their large capacity Niles VTL.
