SCHMITT LAUNCH ULTRA SMALL IN-SPINDLE BALANCER Schmitt have released one of the smallest centres with automatic tool changing based machine spindle. The whole balancing In-Spindle balance heads available for on HSK taper systems, where space inside sequence is automatic, and the digital automatic dynamic balancing of production grinding machines and high speed spindles. automated clamping assemblies, hydraulics 1000 firmware means this This vibration can lead to poor surface finish seconds, eliminating time consuming pre- on the part, bad geometry, decreased The SBS balancing system is a permanent balancing techniques.

Excessive grinding electric vibration sensor monitors spindle vibration due to grinding wheel or tool-holder interface. HMI ‘virtual keypad’ software is accelerated wheel usage – not a favourable unbalance. This information is fed to a digital available to run on any MS Windows based As part of their well known SBS (Schmitt Balance Systems) range, and at only 28mm diameter, the internal balance head is designed specifically for applications where space inside the grinding or machining spindle is very limited. Tool and cutter grinders with small spindles cutting using super-abrasive or diamond wheels are one application machines are often running direct drive spindles with grinding wheel surface speeds in excess of 100m/s. At this kind of velocity a perfectly balanced grinding wheel or toolholder assembly is essential, as even very small amounts of unbalance result in high centrifugal forces on the spindle, and consequently, excessive machine vibration. control unit that in The SBS system is available to machine tool OEMs or as a retrofit package to end users from Schmitt Europe based in Coventry, UK. contact transmission Schmitt will be exhibiting the 28mm In- Spindle balance head and other products at this years EMO exhibition in Hannover at mechanical head Leofric Court United Kingdom characteristic when working with expensive CBN or diamond wheels.
