Absolute Balancer AUTOMATIC BALANCERS ON 1 AND 2 PLANE FOR GRINDING MACHINE The range of ABSOLUTE BALANCER® heads, exclusive Balance Systems design, represents the state-of-the-art in the automatic balancing technology. ABSOLUTE BALANCER® are available in all configurations for 1 and 2 plane. They ensure unprecedented performances both in terms of execution speed and final accuracy.The balancing heads are managed via contact less control (NoLink) by VM25 modular multifunction unit. Exclusive Balance Systems design with moment-free architecture Designed in a wide range of diameters and shapes for built-in spindle mounting, starting from diameter 28mm Embedded rotational speed sensor Operating rotation speed up to 25.000 rpm Residual unbalance achievable at least 10 times less than traditional solutions on 1 and 2 plane Deterministic balancing time Automatic neutral cycle (weights at 180°) Acoustic emission sensor (AE) can be integrated (optional) Corrects all dynamic effects on the grinding spindle, optimizing the surface geometry and quality of the work-piece Increases the machine productivity Increases of the spindle and wheels lifetime Increases of dressing interval with reduced environmental impact Doe

The needs For grinders in a production environment, it is becoming increasingly critical to obtain high dimensional control, geometric tolerances and surface finish qualities while maintaining or improving productivity levels. The highest quality is achieved with a grinding wheel where both the static and the dynamic components of the unbalance are virtually eliminated. The lack of homogeneity of the grinding wheel material, its consumption during use and the absorption of the coolant together with the tolerances of mechanical assembly, create an overall unbalance which affects the quality of...

Typical applications for 2 plane balancing • Gear grinding machines with single or double grinding wheel (roughing and finishing) • Cylindrical grinding machines between centers in configuration with one grinding wheel on both sides of the spindle • Cylindrical grinding machines with super-abrasive wheels ( e.g.: CBN) requiring an additional correction plane • Centerless grinding machines • Cylindrical grinding machines with grinding wheels pack Spindle with double side access and without internal bore. The control is performed by contact less collector embedded with the balancing head body on...

The VM25 multi-function modular system The control unit VM25 can integrate, at any time, additional functions, in order to complete the application in the machine: • Manual pre-balancing of the grinding spindle on 1 and 2 plane • Control of the wheel-piece contact (e.g. “gap” for air gap elimination and “crash” for collision detection), with acoustic emission and power sensors • Control of the wheel-work dressing profile, with acoustic emission sensors • Pre-in-post process control of diameters using absolute gauge device (Top Gauge Absolute) on stationary or rotating parts with continuous and...
