Tradition Meets Modernity
Flat Guides
Excellent Damping Properties: Box or flat guides effectively absorb vibrations from the machining process by transferring them into the machine bed due to their large contact surface. Hand-fitted and scraped by experienced staff, these guides ensure precision. Central oil lubrication provides continuous lubrication with bedway oil, while the Turcite coating on the sliding surface offers excellent emergency running properties. Machines with flat guides are more durable and can handle higher chip volumes. Thanks to these unique features, they are considered particularly powerful and reliable.

Features of Hi-TECH 700BB / BB+ – Big Bore Lathe
Extra Large Hollow Spindle
Perfect for Tube Machining: BigBore lathes impress with their large hollow spindle diameter, allowing large workpiece diameters to be loaded or unloaded through the spindle or deeply clamped. They excel particularly in machining large tubes, utilizing pneumatic power chucks on both the front and rear sides of the spindle.
| Max. Bar size | mm | 180 - 295 | |
Wide Turret Disk
Maximum Stability and Precision for Your Tools!: Our wide double-row turret enables the use of particularly long turning and boring tools, secured with two holders for significantly higher holding torque. This design effectively reduces vibrations, improves tool life, and optimizes surface quality, making it process-reliable and cost-effective, especially for large length-to-diameter ratios. Even standard turning operations benefit from the superior stability of the wide turret disk, while actively vibration-damping tools can be integrated.

Machines with flat guides are more durable and can handle higher chip volumes. Thanks to these unique features, they are considered particularly powerful and reliable.
Powerful Gear Spindle
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.

Driven Tools
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.
Steady Rest Carriage
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.
High-Quality Pretensioned Ball Screws
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.
Excellent Chip Disposal
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.
