PRESS INFORMATION

A range of precision and standard centreless ground shafting is available from mechanical drive components specialist, Ondrives Ltd of Chesterfield.

The precision centreless 303 stainless steel ground shafting is manufactured to h6 tolerance with diameters available from 2.992mm up to 29.992mm as standard. Most are available in standard lengths ranging from 300mm up to 1000mm maximum. Specials can be machined upon receipt of customer’s drawings, with higher surface finishes, tighter straightness and diameter tolerances all available if required.

The unhardened steel centreless version is available in diameters ranging from 2.00mm to 30.00mm & all are available in a choice of three different lengths – 333mm, 1 metre and 3 metres. These shafts are suitable for hardening, and this can be achieved very easily the company states. Heat slowly to 760ºC - 800ºC, austentitize until the temperature is uniform and then quench into well agitated water. The quench hardness is 65-68 Hrc (approx) and needs tempering immediately after hardening, preferably before the tool reaches room temperature. Temper for a minimum of one hour at temperatures between 180ºC to 350ºC, dependant upon the final hardness required. Specials are also available for this shaft, please fax over your drawing or sketch so our technical department can raise a no-obligation, free of charge quotation for you.
