A new precision gear grinding centre from PTG Holroyd hasn\u2019t simply been designed to bring greater levels of efficiency and accuracy to the production of specialised gears and tooth forms. The new machine, called the HG350-G, is also the first from PTG Holroyd – and believed to be the first in the UK – to use Siemens\u2019 new Sinumerik ONE future-proof CNC, the successor to the automation specialist\u2019s 840D CNC.<\/p>\n
PTG Holroyd has committed in excess of \u00a31.6 million to develop its brand new gear grinding centre, a machine which has been designed to give the company a significant edge in the horizontal form grinding of high-quality gears. \u201cWe plan to build two HG350-G machines to begin with,\u201d comments Regional Sales Director, Mark Curran. \u201cOne will remain on site in Rochdale for R&D purposes. The other has been purchased by a long-standing PTG Holroyd customer.\u201d<\/p>\n
In designing the HG350-G, PTG Holroyd\u2019s goal was to offer customers much more than a new generation machine for the one-off and batch grinding of high-accuracy precision spur and helical gears, as well as worms and screws of up to 350 mm in diameter. \u201cWe wanted to create a machine with class-leading integrated safety and failsafe features, rich, real-time reporting of machine health and performance data, as well as the highest levels of industrial security,\u201d adds Mark Curran. \u201cOther non-negotiables for the HG350-G included being exceptionally intuitive for operators, easily able to accommodate each customer\u2019s Industry<\/p>\n
4.0 strategy and being future proofed against legacy software issues. These were all attributes that the Sinumerik ONE CNC was able to offer. Additionally, the associated software suite\u2019s ability to create a digital \u2018working\u2019 twin of the machine on the desktop before build commenced was a considerable advantage.\u201d<\/p>\n
\u201cTypically, when creating a new machine tool, you begin with a vision \u2013 a concept of what you would like your new machine to achieve,\u201d says Mark Curran. \u201cThat said, software can\u2019t normally be written or mechanical components ordered until the design is complete and has been verified \u2013 and, even then, changes may be required. By working in close collaboration with Siemens, however, we were also able to embrace the \u2018Create my virtual machine\u2019 and \u2018Run my virtual machine\u2019 software capabilities of the Sinumerik ONE suite, in order to create and run a \u2018digital twin\u2019 of the proposed HG350-G.\u201d<\/p>\n
Used in tandem with its own internal machine design packages, these capabilities enabled PTG Holroyd to build a virtual machine on the desktop, then grind virtual gears and threads, test safety and failsafe capabilities and eliminate potential problems before commencing the machine build. \u201cAt PTG Holroyd, we pride ourselves on a \u2019right first time\u2019 approach,\u201d adds Mark Curran. \u201cThe virtual machine build and run capabilities offered in the Sinumerik ONE suite further helped us to fulfil this ethos, enabling us to input and observe entire manufacturing cycles before commencing a physical build. This will also make acceptance testing with future HG350-G customers simpler and straightforward. In short, they will be able to sign off on their gear grinder before it has even been built.\u201d<\/p>\n
\u201cIt has been a privilege to work with the PTG Holroyd team to incorporate the capabilities of the new Sinumerik ONE CNC into the HG350-G gear grinder and to help utilise the benefits of the Sinumerik software suite to perfect the machine\u2019s design,\u201d comments Siemens\u2019 application engineer, Garry Mepham. \u201cPTG Holroyd is an important customer of Siemens in the UK and I am confident their decision to use Sinumerik ONE will provide significant benefits \u2013 both in terms of machine design & development and by providing customers with future-proof capabilities and control.\u201d<\/p>\n
Replacing PTG Holroyd\u2019s well-established GTG2 model, the HG350-G features the high power required for deep grinding operations. A specially developed extended machine bed allows screws and worm shafts of up to one metre in length to be accommodated. Dedicated software compensates for helical twist, and full topological capability comes as standard.<\/p>\n
Embracing the Sinumerik ONE CNC\u2019s Profinet capabilities, IO-Link communication technology will be offered with all new HG350-G machines. \u201cWe selected IO-Link for its significant data-handling capabilities and its ability to communicate at every level of the production process, with rich levels of data such as pressure, temperature and detailed machine diagnostics,\u201d says Mark Curran. \u201cRFID scanning is a further option that will assist HG350-G users in achieving new levels of performance. Particularly suitable for machines destined for production cells, the feature will all but eliminate human error by helping ensure that chuck, collet, cutter and tailstock, in fact virtually any component or tooling item that needs to be switched between manufacturing cycles, is correctly changed for each gear grinding operation.\u201d<\/p>\n
Maintaining the Holroyd tradition of building machines that simplify even highly complex manufacturing processes, the HG350-G combines extreme rigidity with high power for both CBN and conventional deep grinding operations. On-board features include: automatic coordinate adjustment, in-cycle wheel dressing, integrated profile management and coordinate measurement. Grinding cycles are included for: spur gears; helical gears; crowned helical and spur gears with root or tip relief; worm gears of the form ZK, ZI, ZN and ZA; dual lead (duplex) worm gears; splines. The HG350-G also features PTG Holroyd\u2019s Profile Management System (HPMS) for highly accurate profile grinding, while an advanced touch-screen interface allows the operator to enter design drawing information directly into the machine.<\/p>\n
