Twin Spindle Turning Center & Gantry Loader Series Overview

Introduction
The document outlines the specifications and features of the Twin Spindle Turning Center and Gantry Loader series, highlighting their automation and productivity capabilities.

Main Spindle Specifications
The series includes models such as PUMA HT230T, HT230TG, H250T, QL200H, H310T, and QL300H. Spindle speeds range from 3500 to 6000 r/min, with motor power between 7.5 kW and 22 kW. C-axis control allows precise positioning with 0.001-degree increments.

Power-Torque Diagrams
These diagrams show the performance of different spindle models under various conditions, illustrating torque and power output at different speeds.

Turret and Tooling System
The series features turrets with up to 24 tool stations for complex machining. Tooling systems are recommended based on export conditions, with various tool holders and boring sleeves available.

Machine Construction and Working Range
Machines are designed with wide wrap-around rectangular guideways for rigidity and accuracy. The bed design minimizes vibration, supporting reliability in cutting conditions. Maximum turning diameters and lengths vary, with rapid travel speeds of 24 m/min.

Gantry Loader Application
The gantry loader system enhances productivity with twin spindles and turrets, handling diverse components. Axis travel is specified for different models, with ergonomic features for chip disposal and accessibility.

Tool Interference and Axis Travel
Diagrams provide insights into tool interference and axis travel, ensuring efficient setup and operation. Specific measurements for turning diameters and lengths support precise machining.

Conclusion
The series offers versatile automation and high productivity, with detailed specifications and diagrams aiding manufacturing decision-making.
