AZ spindle and motor spindle repair
Brochexpress is an independent workshop specializing in the repair, maintenance and diagnostics of AZ spindles and motor spindles. AZ is an Italian manufacturer from Thiene (Veneto), known for its RU series universal CNC cylindrical grinders and its crankshaft and cylinder grinders.
AZ, an Italian builder of CNC cylindrical grinders
TLDR: AZ S.p.A. (Thiene, province of Vicenza, Italy) traces its origins back to 1953 (Zanrosso). It developed Tecnodue in 1976 and builds, among others, the RU series of universal CNC cylindrical grinders. More than 3,000 crankshaft and cylinder grinders have been sold in over 90 countries.
AZ is ISO 9001 certified, employs between 20 and 49 people and has worked for the aerospace industry since 2006. Its RU series machines are universal CNC cylindrical grinders, with a wheel spindle, a workhead spindle and, depending on the configuration, an internal grinding attachment.
Wheel and workhead spindles for cylindrical grinding
TLDR: On an AZ grinder, part accuracy depends on the wheel spindle and the workhead spindle. Their specifications are not published.
An AZ wheel spindle that develops play or runout shows up immediately on the part: roundness, surface finish, chatter marks. Power ratings, speeds, wheel dimensions and bearings are not given in the sources we consulted: we confirm them in our quote, from the machine's nameplate.
Beware of the "RU" name clash. The designation "RU 28-100" is also used on grinders from the Gendron brand. We found no source confirming any link between the two: spindle specifications must be confirmed machine by machine, from the nameplate.
