Jones &
Shipman - Holroyd, leaders in the supply of high quality, precision cylindrical,
surface, creepfeed, gear and rotor grinding machine systems, have introduced
three machines plus two full size wheelhead modules: a novel multi-wheel design
from Jones & Shipman and a stylized concept dressing unit from Holroyd both from
soon to be released new cylindrical and gear grinding machines.
"The three market-leading machines are all from the Jones & Shipman product range: a Suprema 650 toolroom, medium production cylindrical grinding machine, a Dominator 624 creepfeed, profile and surface grinding machine and a TechMaster 634 high-precision heavy duty surface grinding machine," said a spokesperson. "The Suprema and Techmaster machines also incorporate Jones & Shipman's feature-packed 'Easy Control,' which is simpler to use, quicker to set and enables parts to be ground within the same cycle time as a conventional CNC.
"The Suprema 650 Easy cylindrical grinding machine incorporates a universal wheelhead, and has a grinding capacity of ¯12-inches x 25.5-inches (¯300 mm x 650 mm) between centers. Models are also available in 40-inches and 60-inches (1 m and 1.5 m) table capacities. While this model, with its universal wheelhead, allows for internal and external grinding, plain straight approach and angle head options are also available, all achieved with very low capital outlay, ensuring fast payback for users.
"Jones & Shipman creepfeed and surface grinders also feature the well-known, award winning, Dominator creepfeed range and the heavy duty, touchscreen-controlled TechMaster surface grinder range.
"Controlled by a GE-Fanuc CNC, the Dominator 624 delivers major benefits with respect to structural rigidity and machine dynamics. This is the result of an innovative design that dispenses with a reciprocating table and a wheelhead column giving the additional benefit of a very compact overall machine footprint.
"Originally designed for use in toolrooms and mold making facilities, the Techmaster range has now also achieved considerable success in the aerospace and medical industries due to its combined quick set-up, fast metal removal rates and high precision. This heavy-duty 634 model offers a 24-inch x 12-inch (600 mm x 300 mm) grinding capacity, with a vertical capacity of 15.75-inches (400 mm) under the grinding wheel. The machine provides affordable and sophisticated surface grinding with simple set-ups, is highly accurate, very stiff and has a high metal removal rate. Other surface grinders are available up to 47-inch x 24-inch (1,200 x 600 mm) capacity.
"The 'Easy Control,' as used on the J & S Techmaster and Suprema machines, offers the key advantage of bringing traditional manual machinists into the world of CNC technology, without any additional programming knowledge. In addition, the control can make complex and precise grinding operations far easier to execute than has previously been possible.
"Built around a GE-Fanuc touchscreen, the 'Easy Control software suite' from Jones & Shipman removes the requirement for operators to input code, instead providing highly flexible graphical, menu-driven programming. This allows the 'Easy Control' to provide faster turn-around and quicker setups than conventional CNCs, while retaining all of their functionality. Featuring 0.00005-inch (10th-micron) programming, standard cycles and even thread and contour grinding, the 'Easy Control' is available as an option in place of a conventional CNC on all current Jones & Shipman grinding machine ranges.
"The Holroyd dressing/grinding concept from its high precision gear and thread grinding machines will feature a twin diamond disc dressing unit with full 2-axis control, a 20-inch x 4-inch (500 x 107 mm) grinding wheel and a component capacity of 14-inch x 60-inch (350 x 1,500 mm). These will also be showing a formed wheel and corresponding precision gear component.
"The totally new modular wheelhead design from Jones & Shipman will feature twin back-to-back grinding wheels each with a capacity up to 20-inches x 4-inches (500 x 100 mm), plus an internal grinding spindle. Due to its unique modular design the back-to-back option is just one of many new multiple external/internal wheel configurations available to the customer which will make possible ever more complex component machining. This wheelhead which will be fully operational will also be shown rotating in this instance utilizing a Hurth coupling, one of the many features available with this new design."
