©Balance Systems The VM25 is a modular fully programmable system designed for high performances applications in grinding machines. It is able to provide solutions for: - Automatic balancing of the grinding spindle on 1 and 2 plane - Touch detection to control the contact grinding wheel-work piece and grinding wheel-dresser, by using acoustic emission and/or power sensors - In-process and post-process gauging (absolute or comparative) Features • Modular setup fits to the machine architecture on which it is installed • It is available in several configurations: table or remote control unit • User’s graphic interface based on ISO symbols • Total integration with the machine controller (commands and remote programming) • TCP/IP connectivity for service operations and remote diagnostic • It is provided with the software application “VM25 Service” for backup, restore and software upgrade operations • Each installed function is fully independent. In case that a function is temporarily not available, it can be disabled and the remaining system can continue to operate • A functional upgrade can be made at any time Benefits • Ergonomic and easy to setup • Decisive in optimizing the production process and the quality of the machine • Extends lifetime of the machine components (spindle, grinding wheel and dressing tool), reducing the environmental impact • Does not require surveillance • Can be integrated in any type of grinding machine, both new and retrofitting

System features Each system is able to manage in one application: • Up to 4 balancing functions for 1 and 2 plane • Up to 4 touch detection functions • Up to 4 in-post process gauging functions (absolute or comparative) • Profibus DP or profinet interfaces The VM25 control unit is provided with a panel with color display as well as a VM25 HMI software application for PC ®Windows. Both of them can be used by the operator to configure the application through menu and to manually control the entire device. The PC ®Windows VM25 HMI software package includes graphic libraries allowing the integration...

Touch Detector function Typical process signals touching conditions Frequency analysis during the system setup Features • Up to 4 channels for acoustic emission (AE) sensor • 1 channel for a network up to 8 power transducers • Up to 4 simultaneous processes • Up to 16 part program to control the touching conditions (e.g. grinding wheel-work piece and grinding wheeldresser) • Selective digital filtering based on the frequency analysis Benefits • Essential to reduce cycle times • Gives a perfect control of the shape of the tools (e.g. the grinding wheel profile) • Improves safety and reduces maintenance...

In-Process Gauge function Features • 4 channels for gauge heads “plug & play” (e.g.: 2 diameters simultaneously) • 2 simultaneous processes with comparative or absolute measuring • Wide measuring range in comparative mode (master) for multi-diameter application. Up to 25.4 mm with a resolution of 0.1 pm without retooling • Absolute measure (w/o master) of diameters from 4 to 1000 mm • 32 part-programs (external diameter, internal diameter, thickness, taper, active and passive positioning, etc.) • Measurement of smooth and interrupted surfaces by hardware or software synchronization • In-process...
