No belts or electric pumps to replace. Pump is driven off the wheel spindle and direct drive motor for the wheel. The VG19 Valve Grinder/Refacing machine will reface the valve and also recondition the valve stem. The machine is easy to operate, the rigid base is cast and provides precision. The longitudinal and transverse carriages slide on dovetail guides, which make is possible to adjust the clearance. The transverse carriage moves the grinding wheel - is driven by the hand crank, where as the longitudinal carriage - serving to feed the work piece - is driven by the handle with adjustable stroke. The valve headstock has an adjustment range from 30° to 60°. The valve is clamped in the head stock by a collet, three collets are standard, which ensure maximum stiffness and best centering of the valve and high precision operations. The collet system offers the tightest concentricty for refacing the valve. Valve to adjust coolant flow. Uses water based coolant for the best finish and easy clean up. The standard machine includes coolant attachment with gear pump and settling tank, incorporated in the machine base.Options include steel base, rocker arm fixture, a wide range of collets and CBN grinding wheel
The experience start on 1953 under the logo Zanrosso on the field of automotive after sales service with the production of lathes for drums and discs for veichles. In the 1976 born Tecnodue company specialized on garage equipment like two post lifts and gas analyzer.
Year by year the product improve till became a world wide leader on machine tools for engines rebuilding, marine engines and railways engines.
In the next years AZ has grown as leader in the production of crankshaft grinding machines for energy, locomotive and marine field up to 12 meters length, sold all over the world 3000 crankshaft and rolls grinders and this permits AZ to be called "the crankshaft specialist".
On 2006 a new challenge. With the achieved experience AZ enter on the market of the special grinding machines especially for the aerospace.
AZ spa is a company with quality system ISO9001 certified by DNV GL.
The presence of a large number of qualified and loyal customers and the presence of AZ in more than 90 countries proves its success.
The aim of AZ is to solve grinding special problems giving to the customers not only a machine but a complete solution.
The machines produces by AZ perform the most advanced mechatronics solutions. The measurement, the movement, the controls are choosen on the top worldwide leader supplier and their combinations with AZ engineer creativity produce one of the most sofisticate range of product today on the market.
Bejond the mechanical and electronic knowledge, AZ applies to their machines an innovative IT and web technology for assistance, training and after sales service monitoring in real time the working process.
