An unrivalled price-to-performance specification that will appeal to both toolrooms and companies involved in one-off or volume production is claimed for a Czech teach-in cylindrical grinder.

Manufactured in the Czech Republic by Cetos, the BUA 25Auniversal cylindrical grinding machine with teach-in CNC systembeing shown at MACH 2002 by Ward CNC boasts an unrivalledprice-to-performance specification that will appeal to bothtoolrooms and companies involved in one-off or volume production.With a swing diameter of 500mm and a distance between centres of1500mm, the Cetos BUA 25A can accommodate workpieces of 500kg.Workhead swivel and speeds are 90 deg and 18 to 560 revs/min,respectively, and wheelhead swivel is quoted as + 40 deg to -15deg. Able to utilise 500mm diameter grinding wheels, wheel speedis 1,695/1,960 revs/min and peripheral wheel speed is 45m/sec.Table feed rate is 0.05m/min to 5m/min. The K51 teach-in CNC is ahigh-performance control system that allows grinding to beperformed under manual control or automatically, while alsoaccommodating longitudinal grinding with auto infeed at tablereversal points, wheel dressing and intermediate wheel dressing.In manual mode, wheelhead infeed length and rate control is via acontrol knob, which can be used to increase the step ten-fold.For manual longitudinal grinding, automatic infeed can beadjusted at the reversal points.

In volume mode, programs can becreated automatically during the grinding of the first workpieceby teach-in methods, with no special programming knowledge beingrequired.

Programming can also be by direct entry of cycleparameters.

As standard, up to 10 teach-in programs can be stored(ie five plunge-cut and five longitudinal grinding programs) andprogram changes can be easily accommodated for further work sinceeach change is automatically remembered.

The BUA 25A is one of anumber of Cetos grinders available from Ward CNC - which includesinternal/external, single/two-wheelhead cylindrical plunge andcrankshaft-type machines - as well Hankook two-axis turningmachines, Union horizontal live spindle machining centres,Soraluce travelling column and travelling table milling machinesand bed mills, Toshulin vertical boring, turning and millingmachines, as well as Kia CNC lathes, turning centres, andvertical and horizontal machining centres - representatives ofwhich will also be on show at MACH 2002 - NEC, Birmingham: April29-May 3 Hall: 4.
