The SIRIUS-850 is a vertical machining centre with a cross-table design. The Y-axis is equipped with four very wide, hand-scraped box guideways designed for heavy workpieces. The high-torque, oil-cooled HWACHEON spindles (8,000 or 12,000 rpm, 420 Nm, 30 kW) enable high material removal rates and excellent surface finishes with maximum precision, even during extended operating times.

Integrated Spindle Motors

At Hwacheon, only the most experienced and highly trained employees work in spindle production. Spindle assembly takes place in climate-controlled clean rooms, and all spindles undergo extensive endurance tests and inspections before being approved for installation.

Oil-Chilled Spindles

Hwacheon’s spindle cooling system ensures a continuous flow of oil through the spindle bearings and around the surface of the integrated motor, lubricating and tempering the entire spindle. Temperature sensors monitor and actively regulate the temperature, while heat increases are compensated for on the control side.

Box Guideways

The machining centre is equipped with four very wide box guideways on the Y-axis. These effectively absorb vibrations through the solid cast iron bed, enabling high table loads of up to 4 tonnes.

Air Floating System

To reduce break-loose torque and the stick-slip effect, the gaps in the box guideways are pressurized with compressed air. This ensures optimal distribution of guideway oil and exceptionally smooth movement over short distances and during oscillatory motions.

Optimal Stability for Heavy Workpieces and Cutting Tasks

For twenty years, the SIRIUS-850 has been in demand worldwide for its stability and performance. Among discerning users, it stands for reliability and precision. The box guideways guarantee excellent surface finishes, long tool life, and superior vibration absorption. The use of compressed air on the bearing surfaces of the guideways enables incomparably smooth and gentle movements, even with heavy workpieces, which is reflected in contour accuracy and surface quality. The easily accessible and observable workspace simplifies operation. Easy crane loading, full enclosure of the workspace, and extensive Hwacheon software features make the SIRIUS-850 a highly productive and ergonomic machining centre.

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

SIRIUS-850 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.

Innovative Air-Floating System

SIRIUS-850 has Air-Floating-System available

Air Assistance for Smooth Precision and Perfect Control!: By using compressed air in the gap of the flat guides, we effectively reduce breakaway torque and minimize the slip-stick effect, ensuring optimal distribution of bedway oil and smooth movements even over short distances. At Hwacheon, we rely on solid craftsmanship and manufacture our flat guides in-house, including Turcite coating and precisely machined lubrication and air grooves. This technology ensures uniform motion behavior, resulting in the highest contour and positioning accuracy.

High-Quality Spindle

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.

Internal Coolant Supply

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.

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.
