The HSC machining centres of the SIRIUS series (UM/UL+/UX) have been Hwacheon’s most successful machines for tool, die, and mould making for nearly 20 years.

As a domestic market leader in this segment, the name Hwacheon stands for the highest precision, reliability, and efficiency.

For us, as one of the oldest South Korean machine tool manufacturers with over 60 years of experience and forward-looking expertise, there is only one standard of quality: It must always be the best. High machine availability and peak productivity are the results of our decades of experience in development, design, and production. This is why we rely on in-house spindle manufacturing, our own foundry, and bed machining—because every detail matters. Only in this way can our machine tools consistently meet the highest demands over the long term.

The three-axis machining centre with a portal design and reinforced rear wall ensures high precision and excellent surface finishes—even with difficult-to-machine materials. Designed for HSC and HPC applications, these machining centres meet the strictest requirements for accuracy and tight tolerances.

With a maximum table load of 800 kg, the SIRIUS-UM accommodates workpieces measuring 850 x 500 mm. Thanks to powerful feed drives and high-quality linear guideways on all axes, it achieves rapid traverse speeds of 24 m/min. The fast tool changer with 24 stations (optionally 30) enhances cost-effective production. Weighing 8 tonnes, the SIRIUS-UM offers the stability and smooth operation typical of Hwacheon machines. The Meehanite cast bed, produced in our own foundry, has been optimized for thermal stability and rigidity using FEM simulations.

For every application, we offer a choice of three temperature-monitored, oil-cooled built-in spindles manufactured in-house:

  • Standard: 20,000 rpm with a drive power of 18.5/11 kW and 60/17.5 Nm (10 min/const.)
  • Optionally: 20,000 rpm with a drive power of 22/18.5 kW and 118/80 Nm (15 min/const.)
  • Optionally: 32,000 rpm with a drive power of 18.5/13 kW and 4.1/5.9 Nm (1 min/const.)

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.

Dynamic Linear Guides

Speed and Dynamics Combined: Linear roller guides provide high dynamics and rapid traverse speeds. The workpiece weight is transferred linearly to the rollers, which must withstand enormous pressure at contact points. Therefore, we exclusively use linear roller guides from renowned manufacturers.

HSC Spindle

Ultimate Precision, Maximum Speed: HSC spindles utilize high speeds and fast feeds to achieve higher material removal rates despite reduced cutting depth. This combination lowers machining forces and minimizes heat input through rapid chip removal. Primarily used in tool and mold making, they meet the highest standards for surface quality, dimensional accuracy, and contour fidelity.

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.

Dynamic Linear Guides

Speed and Dynamics Combined: Linear roller guides provide high dynamics and rapid traverse speeds. The workpiece weight is transferred linearly to the rollers, which must withstand enormous pressure at contact points. Therefore, we exclusively use linear roller guides from renowned manufacturers.

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.

Thermally Insulated Machine Components

Consistent Precision Despite Environmental Influences: Fluctuating temperatures due to drafts or waste heat can impair machining accuracy. Thermal insulation of relevant machine components significantly reduces this effect and maintains machining precision. This ensures quality regardless of environmental influences.
