Each SIRIUS-UM/UL+/UX machining center is manufactured to perfection with Hwacheon’s workmanship that is the quality recognized and envied by everyone in the industry; and it guarantees to give you a perfect result every time.

The high performance spindle which integrates Hwacheon’s Oil-jet Cooling technology ensures consistent quality result after hours and hours of operation, while the machine’s Optimal Machining system gives you a total production solution, from tool selection to final product. SIRIUS-UM/UL+/UX is designed using 3D simulations and the FEM analysis to achieve structural rigidity which can translate to quality product results; while the Hwacheon designed machining software components enhance safety and the work efficiency in your organization. The SIRIUS-UM/UL+/UX is configurable with many different options so that it can integrate better in your work environment and application.

Rigid Bilateral Gate Structure Machine Frame

The gate structure firmly supports the x-axis drive and diverts the load, vibration, and heat from the upper section of the machine evenly throughout the frame-the feature which helps too keep the feed drive stable after hours of operation. Also, the short distance between the X-axis drive and the tool’s contact point is a plus for maintaining the rigidity and for enhancing the machining precision.

Spindle Assembly

The Hwacheon clean room assembly facility, where the super-precision, super-speed spindle built inside SIRIUS-UM/UL / UX is manufactured, maintains optimal temperature and humidity, and is kept free of any foreign substances. Only the most skilled master engineers are allowed in the assembly facility, in the production of only the best equipment to comply with the toughest quality standard in the industry.

Oil-jet Cooling System

The jet of oil is injected directly onto the spindle bearing for effective cooling, and the motor and the spindle assembly are jacket-cooled to limit the displacement caused by heat.

Hwacheon Machining Software Components

The Hwacheon’s developed machining software monitors different variables related to the work environment and machining conditions and makes adjustments for best quality results and optimum work efficiency.
