Hi-TECH 850BB / BB+ – Big Bore Lathe

High-Torque Drives for Heavy Machining: Lathes with gear spindles offer significantly higher torque than those with motor spindles. By selecting the appropriate gear ratio, torque can be optimally utilized within the speed range of the ideal cutting speed. Large spindle bearings and shaft diameters robustly absorb process forces and peaks, ensuring high durability. The gear stage can be conveniently selected via M-functions.

Greater Flexibility and Time Savings: Lathes with a Y-axis enable 3-axis interpolation movements and the creation of off-center bores and milling operations. This allows workpieces to be fully machined in a single setup, eliminating operations on other machines and increasing machining accuracy. Additionally, they optimize grooving and parting processes by reducing lever forces for faster workflows.

Precision and Versatility Combined: Driven tools on lathes significantly expand machining capabilities. They enable milling, drilling, and other processes directly on the lathe, reducing re-clamping operations and minimizing downtime. Using various tools in a single setup increases machining accuracy and boosts overall productivity.

Stability for Precise Results: The steady rest ensures maximum precision for long workpieces through optimal support. It reduces vibrations, improves surface quality, and enables precise machining even for demanding projects.

Consistent Cooling and Lubrication for Maximum Precision: Our in-house manufactured spindles are cooled and lubricated by an innovative air-oil aerosol system, while temperature sensors ensure constant monitoring. This advanced technology guarantees exceptional durability and outstanding smoothness. Experience maximum precision with minimal thermal growth for consistent performance even under the most demanding conditions.

ICS Makes the Difference!: The internal coolant supply (ICS) delivers coolant directly to the cutting edge, optimizing lubrication and chip removal. It boosts productivity, extends tool life, and enhances process reliability.

Thermal Stability for Precision and Reliability: Pretensioned ball screws reliably and stably compensate for thermal expansion. This technology prevents unwanted elongation of the spindles, ensuring lasting precision and consistently high machining accuracy over extended operating periods.

Perfect Chip Removal for Your Machine!: Our innovative chip disposal systems reliably remove chips, reduce heat, and optimize machining. High-quality components ensure uninterrupted operation and maximum process reliability.
