Cylindrical grinder does one-off and
small batches
Cylindrical grinder provides a highly flexible, single-cycle universal solution to the finishing of one-off parts or small batch runs.
Developed to provide a highly flexible, single-cycle universal solution to the cylindrical grinding of one-off parts or small batch runs, the latest Danobat G-41 cylindrical grinding machine is able to accommodate external, internal diameters, faces and tapers Now marketed through 600 Centre of Shepshed near Loughborough, the Danobat G-41 Universal 'U' machine can also be specified as a lower cost 90 (degree) approach conventional cylindrical grinder designated 'S'

Within three months of installation a Fanuc Robodrill, Raytheon Marine Company based in Portsmouth calculated savings of GBP6,000 on components it produced due to faster set ups.
Wire EDM machine uprated to cut quicker
Fanuc has extended the capacity, specification and performance of its Robocut Alpha-1iA wire cut electro discharge machine (EDM) to provide high accuracy performance cutting at up to 300mm2/min.
The machine has been developed in order to maximise the potential of cubic boron nitride (CBN) wheel technology through high orders of design rigidity.
This means high performance, accuracy and repeatability have been developed into the machine.
When these features are combined with Danobat's DanOp, DanBop and DanCad software modules, flexibility and operational functionality provide a high performance grinding package for components up to 348 mm diameter by 1,000 mm long.

Built on a stabilised pearlitic cast iron base with integrated 'double body' table, the machine is compact, stable and very rigid.
Table swivel is +9 degree to -2 degree.
The servo driven table is able to swivel between +45 degree and -15 degree and the workhead will accept components weighing up to 125kg between centres with stepless programmable speed range between 30 and 1,000 revs/min.
The indexing universal wheelhead has zero, 30 degree, 90 degree and 180 degree working positions and the ability to carry external, face grinding or internal grinding spindles.
The universal wheelhead has a 7.5kW drive, 45m/sec wheel speed and 500mm by 80mm by 203mm external grinding wheel and a face grinding wheel.
It also has the ability to carry one of a range of four internal grinding spindles having up to 30,000 revs/min speed and the capacity to grind bores up to 160mm diameter.
With the option of a 90 degree approach wheelhead, this has a 5.5kW, 45m/sec grinding speed and wheel size of 400mm by 63mm by 127mm.
Based on Fanuc 210i control system, software development was seen as important to the Danobat specification.
This has resulted in the DanBop machine control software being classified to be as simple to operate as a manual machine and this is achieved by simply selecting the type of work required.
It can incorporate fully or semi-automatic cycles and accommodate dressing, measurement and changes to grinding parameters.
The DanOp software module accommodates machine functions with soft key programming for set-up, wheel management, work cycling and production management.
DanCad incorporates graphic support direct from CAD systems to enable programming based on component geometry and is able to optimise tasks such as wheel profile creation and dressing.
Options include gauging, gap elimination and crash detection devices, steady rests and a range of filtration and coolant systems.
Dynamic balancing, workholding and a portable handwheel unit are available to help in machine operation.
