VERTICAL HARD-BEARING BALANCING MACHINES

Product catalog summary
Overview
CEMB S.p.A. and HOFMANN Maschinen- und Anlagenbau GmbH form a significant industrial group offering innovative and competitive products with a unified technical and manufacturing philosophy. They emphasize after-sales service to ensure customer satisfaction. Their product range includes universal horizontal and vertical balancing machines for industrial applications and automatic balancing systems for various components such as tires, flywheels, electric motors, and more.
Vertical Hard-Bearing Balancing Machines
These machines are designed for rotors with a shorter axis length compared to diameter or without their own shaft. They use an adaptor for quick loading/unloading, and the residual unbalance is influenced by the centering accuracy of the adaptor. The machines can measure unbalance on one or two planes, with errors corrected automatically by CEMB instruments.
Balancing Machine Spindle
The spindle holds the rotor with high precision, using piezoelectric sensors for measurement. Clamping can be manual or automatic, with a pneumatic system minimizing mobile mass influence. The air distribution system is maintenance-free, enhancing measurement accuracy.
Balancing Machine Drive
The drive motor accelerates the rotor to balancing speed, overcoming inertia and passive resistances. Power requirements for maintaining rotation are generally low, except for rotors with a ventilating effect.
Technical Specifications
The document provides detailed specifications for various models, including maximum rotor weight, unbalance measurement accuracy, motor type, and balancing speed. Models range from V5 to V3000, with different capabilities and features.
Correction Methods
Various static and dynamic correction methods are outlined, including axial and radial drilling, milling, punching, and welding. These methods involve material removal or addition to achieve balance.
Model V5-15-30
This hard-bearing balancing machine is suitable for rotors without their own shaft, offering high precision. It automatically detects unbalance and positions the rotor for correction. It is suitable for both batch work and balancing different rotors, with models available for rotors weighing 5/15/30 kg.
