Detailed Specification
SDM4A-I by balance-systems
Semi-automatic balancing machine
Features
- Semi automatic balancing machine, specifically developed to balance rotors of alternators and similar rotating parts, in a completely automatic way on two planes (dynamic). The unbalances are corrected by removing material by inclined drilling.
- It is composed of: one measuring unit, two drilling units ( one for each balancing plane ) and rotary table with pneumatic pliers for parts manipulation, from measuring unit to drilling units and vice versa.
- Operator interface by industrial PC
- High level of flexibility and quick changeover
Advantages
- Automatic set-up
- High level of flexibility
- High level of repeatability and precision of the unbalance measuring
- Diagnostic and preventive maintenance program
- Quick changeover
- High level of reliability
- User friendly
