Tradition Meets Modernity

Over 80 years of detailed experience: Hwacheon combines traditional craftsmanship with modern technology. Our expertise in machine tool manufacturing ensures high production quality and continuous innovation for future-proof concepts in the German market.

Flat Guides

Hi-TECH 550 has Flachführungen available

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 550

Powerful Gear Spindle

Hi-TECH 550 has Gear spindle available

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.

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.

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.

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.

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.
