RUA CONVENTIONAL UNIVERSAL GRINDING MACHINES

Product catalog summary
Overview
The document provides detailed information about AZ's range of universal grinding machines, designed for various applications including external, internal, face, and taper grinding of components such as transmission shafts, electric motor shafts, and aerospace components.

Machine Specifications
The RUA series is a conventional universal grinding machine controlled by a PLC system with G-CODE interpolation. It features a ball screw system and linear guideways for the grinding wheel movement, and a composite material base for optimal structural integrity and vibration damping.

Headstock and Tailstock
The headstock is adaptable for different clamping systems, while the tailstock moves on linear guideways with continuous force control between centers. Various workpiece supports are available, including manual and automatic systems.

Grinding Wheel Head
The grinding wheel carriage operates on the Z and X axes with an automatic balancing system and vibration control. Dressing is performed by an automatic fixed point dresser.

Control and Measuring System
The machine is equipped with a PLC system for X and Z axis interpolation, supporting multiple functions such as plunge grinding and cylindrical grinding. Optional modular systems for process control include contact, crash, and balancing controls, as well as in-process diameter measurement.

Technical Specifications
The document lists specifications for various models (RUA1000 to RUA3500), including height centers, swing over table, distance between centers, grinding wheel diameter range, and spindle power. Specifications are indicative and subject to change.

Standard and Optional Equipment
Standard features include a PLC control system, variable headstock speed, and centralized lubrication. Optional equipment is available upon customer request.
