Lazzati - High Performance Boring-Mills

Product catalog summary

Overview
The document provides a comprehensive technical description of high-performance boring mills manufactured by LAZZATECH, focusing on advanced systems and features that enhance precision, efficiency, and durability.

Specifications and Systems

LHS - Lazzati Hydrostatic System: Ensures hydrostatic lubrication of the axes, eliminating friction and stick-slip, enhancing rigidity, reducing vibrations, and maintaining precision over time.
DPS - Double Pinion System: Used in rotative and linear transmission, offering high precision and rigidity, allowing for millesimal tolerances and high accelerations.
DCS - Dynamic Compensation System: Compensates for headstock drop during movement, ensuring error-free operation.
TCS - Thermal Control System: Controls temperature increases from spindle rotation and head sliding, maintaining machine accuracy by keeping temperatures close to ambient levels.

Machine Features

Mobile Head: Made from fine-grain perlitic cast-iron, includes controls for spindle rotation and a thermo-stabilization circuit to prevent spindle elongation.
Automatic Tool Changer: Managed by CNC software, allows tool changes on the spindle and accessory heads, with mechanical and hydraulic transmission options.
Birotative Universal Head: Allows automatic spindle positioning in all spatial positions, with hydraulic clamping and cooling circuits to maintain geometric tolerances.

Performance and Accuracy

Working Accuracy: Maintains high standards of precision on diameter and circularity, with specific tolerances for different diameters.
Positioning Accuracy: Details positioning uncertainties and repeatability metrics for various axes according to VDI/DGQ 3441 standards.

Additional Features

Rotary-Riding Tables (TR Series): Offer high structural stiffness and positioning accuracy, unaffected by workpiece weight, using a double preloaded pinion system.
Accessory Automation: Equipped with a pick-up station for accessories, allowing for complete job automation.

Technical Features
The document lists detailed technical specifications for different models of boring mills, including spindle diameter, rotation speed, motor power, and travel dimensions. It also covers the capabilities of universal heads and the maximum load capacities of rotary tables.
