Touchscreen CNC eases surface grinder
operation
Surface grinders offer unrivalled ease-of-use coupled to high productivity, thanks to touch screen CNC and advanced software that enables inexperienced operators produce immediately.
Visitors to the Jones and Shipman stand at MACH 2004 will see further major advances in the simplifying of the Art of Grinding with the first UK showing of two new Jones and Shipman surface grinders The ProGrind 745 'Easy ' with a 750 x 500mm table capacity and the TechMaster 'Easy' to be shown with a 600 x 300mm table capacity, both models having the smallest grinding capacities in their respective ranges

Precision engineers keep grinding in-house
JJ Hardy and Sons, has widened its range of services and raised productivity with the purchase of a Jones and Shipman 'TechMaster' 634X 600 x 300mm table capacity surface grinder.
Jones and Shipman's highly successful flagship model the 524 'Easy', 500 x 200mm table capacity, surface grinder will also be on display as will an 'Easy' version of the popular Ultramat cylindrical grinder shown this time with optional 'B' axis universal wheelhead.
Following on from Jones and Shipman's highly successful 540X/1400X and Format 5 surface grinders, the all new 524, TechMaster and ProGrind 'Easy' models now offer an extended grinding capacity range from 500 x 200mm up to 1000 x 500mm.
And all 'Easy' models have been specifically designed to offer unrivalled ease-of-use coupled to the highest levels of productivity.

Little or no CNC knowledge needed to use grinder
Even an operator with little or no CNC knowledge can precision grind complex shapes, angles and surfaces with a new 524 Easy touchscreen controlled surface and profile grinder.
Icon-based software simplifies complex programming
Icon-based software provides the inexperienced and experienced operator alike with a simple step-by-step guide to to creating programs for the most complex shapes, angles and surfaces.
CNC grinding machine builder updates website
Manufacturer of surface, cylindrical and creep-feed grinding machines has launched its new web site that includes the recently expanded product ranges.
When a high quality GE-Fanuc touchscreen and AC servo motors and control, with years of fault free operation, are combined with Jones and Shipman's own software suite, the result of 10 man years of input, you have features which enable inexperienced and experienced operators alike to be immediately productive.
With functionality comparable to CNC but at lower cost all 'Easy' models are faster to setup via the GE-Fanuc touchscreen and easy-to-use Jones and Shipman icon-based software.
This control provides 'Easy' models with the capabilities to interpolate two or more axes simultaneously to provide precision grinding of complex shapes, angles, radii and surfaces.
The touchscreen control panel is a 'self-teach' intelligent interface allowing the operator to be taken through simple graphical menu driven set-up routines for wheel forming, dress procedures and grinding cycles.
Cycles can be executed individually, or selected in any combination as linked cycles.
Wheel dressing can be initiated In or Out of cycle and Dress-On-Demand for plain or complex wheelforms is standard.
"Dress-On-Demand basically means that the operator can press the Dress button at any time and the machine will stop wherever it is, dress the wheel with full compensation and return to continue from where it left off." On start-up, the 'Easy' control offers the operator three simple options: Manual mode, Dress mode or Grind Cycle mode.
In Manual mode the 'Easy' operates as a simple hand operated machine with manual wheel dress and no set-up procedures.
Work speeds and feeds are simply adjustable via the touchscreen.
Dress mode offers five standard wheel shape options, Flat, Slot, Facing, Vee form and Full ISO with one or two diamonds as needed.
Dressing increments, speeds and frequency allow for roughing and finishing to optimise wheel performance.
Grind mode allows from One to 20 grind cycles, as the complexity of the component dictates from the following cycles, Plunge, Multi Plunge, Area (Intermittent or Continuous), Face grind, Plunge and Face and Multi Plunge and Face.
Quick to use, simple operator friendly features, rigid machine structures, major units manufactured in high-grade cast iron generously dimensioned with the highest levels of build quality to ensure accuracy and productivity combine to make all 'Easy' models dream machines for operators both old and new.
Jones and Shipman are also major manufacturers of both CNC and 'Easy' controlled cylindrical grinders and will be exhibiting at MACH a new version of their well established Ultramat 'Easy' 'self-teach' cylindrical grinder.
Using the same electro mechanical platform as the CNC version the Ultramat 'Easy' on demonstration incorporates a 'B' axis, powered, universal wheelhead which features both left and right hand mounted external grinding wheels plus an internal grinding spindle.
The fully programmed powered 'B' axis is essentially a full servo axis for the rapid positioning between external and/or internal modes.
This enables quick, highly accurate set-up of straight and taper grinding operations of multi external and internal diameters with infinitely variable angular positioning.
Utilising a Holroyd ultra high precision, backlash free, worm and gear assembly, for high reliability and smooth motion, it incorporates a Heidenhain positional encoder, with programmable steps of 0,0001deg.
Engineered for precision, the live and dead single spindle workhead of the Ultramat houses robust, high precision taper roller bearings for superior stiffness while a variable speed GE-Fanuc AC servo drive ensures fast and accurate spindle orientation.
A 'C' axis control option for interpolation of non round components and thread grinding, both external and internal, is available and for the grinding of tapers a rotary encoder can be incorporated in the swivel base giving digital display of angular position.
Developed by Jones and Shipman to offer the operator the advantages of CNC control without the complexity of Traditional CNC systems the Ultramat ' Easy' has the same easy to use GE-Fanuc touchscreen control and Jones Shipman software suites as its Surface grinder siblings.
A final and extremely useful addition to all Jones and Shipman 'Easy' Surface and Cylindrical grinders is the capability for programs produced on these models to be saved to a networked PC or even to a PDA for future retrieval.
The models on show are just four machines within a comprehensive range of precision grinding machine solutions manufactured by Jones and Shipman to meet the rigorous demands of industry worldwide.
Hand-in-hand with its leading-edge product development, Jones and Shipman is also able to exploit its unique capability to supply 'OEM Remanufactured Quality' precision grinders through its worldwide network of distributors and a comprehensive customer service organisation., MACH 2004 - April 19-23 - Birmingham, UK.
