Sophisticated yet simple to operate, this robust, small footprint, machine is already setting the benchmark in the gear grinding machines market.
Designed and developed in the UK it combines rigidity and high power, for either CBN or conventional deep grinding operations, with the highest levels of accuracy and finish. Fast set-ups optimise productivity, whilst the advanced and highly integrated user interface enables an operator to easily produce a finished component from a design drawing.
Such performance is ideal for producing all types of spur, worm and helical gears, and the machine is also configurable for grinding ball screws, small compressor rotors, internal gears and threads.
Typical applications include high-performance aerospace, automotive, precision motion, low noise and master gears.
We provide a comprehensive package of design advice and manufacturing expertise that ensures the highest levels of precision and performance. This, together with our unique ability to manufacture both machines and bespoke components, allows us to fully understand your manufacturing requirements.
Our strict quality assurance system ensures that detailed inspection has been carried out at key stages in the manufacture and assembly of this machine. The completed machine is subjected to a rigorous final inspection and test programme, with selected tests repeated after installation at the customer's site.
Holroyd gear grinding machines are in constant use in our own factory for volume production work, and our technical service staff is therefore well qualified to support our customers worldwide after their purchase, and help them get the best from their investment.
GTG2's advanced and highly integrated design enables an operator to take a typical design drawing and enter the specification - including such parameters as helix angle, pressure angle and module number of teeth - directly into the grinder control, after which the machine performs its production cycle automatically An on-board 3D scanning probe maximises accuracy using profile correction feedback and improves productivity by removing the need for off-machine profile inspection.
These improve production rates by removing the need for off-machine inspection. As a result, parts can be placed in the machine, accurately ground and then measured, and any deviations automatically corrected before completion of the cycle.
The graphical menu driven interface enables the operator to take data from a gear drawing, in a wide variety of representations, to produce profiles and grinding paths to generate the gear.
Transverse profile modifications and flank line (helix) modifications can be applied to the gear in any combination of the following forms. The control has the ability to enter data for both flanks together or each flank independently, allowing the operator to apply different corrections to each flank if required.
This unique feature, as illustrated in the following pictures uses a scanning probe with a resolution of 1 micron in the X, Y and Z axes for measurement and adjustment of the following features:
