CYLINDRICAL GRINDING MACHINES FOR HEAVY DUTY PARTS RETTIFICATRICI CILINDRICHE UNIVERSALI PER PEZZI DI GRANDI DIMENSIONI E PESO

The RUG range of grinding machines has been designed for grinding cylindrical parts of large dimensions and weight. The machine is made of cast iron, designed for heavy loads. The modularity of the grinding wheel head configuration makes this model of machine suitable for external, internal grinding, taper, faces and superfinishing. La gamma di rettificatrici RUG è stata studiata per la rettifica di pezzi cilindrici di grandi dimensioni e peso. Sono macchine con una struttura in ghisa robusta pensata per carichi pesanti. La modularità di configurazione della testa porta mola rende questo modello...

MACHINE CONFIGURATION CONFIGURAZIONE MACCHINA The RUG machine model is designed for grinding large cylinders up to 14 meters long and up to 12 tons in weight. The machine has the following axis configuration: the roller head moves along the Z axis on flat guides and V and the movement is given by a pinion and crematory system with game recovery. Along the X axis the head moves on hydrostatic guides and the movement is given by a high precision ball screw. Axis positioning is controlled by linear encoders. The machine has been designed with two bases connected to each other, one for the movement...

SOLUZIONI PERSONALIZZATE PER OGNI ESIGENZA PRODUTTIV CUSTOMIZED SOLUTIONS FOR EVERY PRODUCTION NEED deformations and the naturai frequencies allowed. The carriage guides of the grinding wheel head and the seats for handling and position control systems are located on the base. tramite metodo ad elementi finiti, per ottenere il miglior compromesso tra le deformazioni strutturali e le frequenze naturali permesse. Sul basamento sono ricavate le guide del carro della testa porta mola e le sedi per sistemi di movimentazione e controllo della posizione.

HEADSTOCK & TAILSTOCK FANTINA E CONTROPUNTA The headstock is designed to mount different clamping systems, the solutions can be customized according to the part to be machined. Headstock and tailstock can both move along the board either manually or automatically, all movements are facilitated by the opening of an air cushion n TESTE STUDIATE SECONDO LE ESIGENZE DEL CLIENTE n WORKHEADS DESIGNED ACCORDING TO THE CUSTOMER’S NEEDS La fantina è progettata in modo da poter montare diversi tipi di serraggio del pezzo, le soluzioni possono essere personalizzate a seconda del pezzo da lavorare. Fantina...

DIFFERENTI SISTEMI DI SUPPORTO E SERRAGGIO IN BASE AL PEZZO DA LAVORARE DIFFERENT SUPPORTS & CLAMPING SYSTEMS ACCORDING TO CUSTOMER WORKPIECE between the contact surfaces. The headstock can be equipped with a counterweight to balance the aximmetric pieces. Headstock and tailstock use ASA and morse cone centering system. The tailstock is equipped with conicity (taper) adjustment and continuous control of the force between centers. The machine can be equipped with different workpiece supports that can be moved manually or automatically along the table: • 2-3 points manual or automatic steady rest...

UNIVERSAL GRINDING MACHINES GRINDING WHEEL HEAD TESTA PORTAMOLA The position of the head can be controlled by closed-loop linear encoders. The wheel turret can mount different types of spindles and grinding wheels, depending on the processing requirements it can have the following configurations: • manually B-axis rotation ± 20° • automatically B-axis rotation ± 30° or ± 360° The grinding wheel can be equipped with automatic balancing system and vibration control. The grinding wheel dressing can be made by automatic fixed point dresser, combined fixed points dresser or roller diamond dresser....
