Sirius 1250 - Hwacheon's line of large size bed milling machines ensures enhanced quality for your large mold machining, such as large display frames, automotive and aerospace parts.
The SIRIUS milling bed series uses a powerful built-in motor shaft and a high-speed, high-precision milling head complemented by Hwacheon's exclusive Oil-Jet cooling system - to ensure powerful machining performance consistently and produce high-quality products after hours of continuous high-speed machining.
Each SIRIUS vertical machining center is designed using 3D simulation FEM analysis to achieve structural rigidity that contributes to product quality.
In addition, Hwacheon also designs machining software to improve safety and work efficiency in your factory.
The machines are upgradeable with a variety of options so they can integrate seamlessly into the customer's work environment and applications.
MAIN FEATURES:
1. High rigidity mechanical structure
The two-sided port structure in the SIRIUS-1250 is an ideal design to distribute vibration, weight, and heat throughout the entire frame.
The machine is built through finite element analysis to minimize frame deformation that may be caused by machining or environmental conditions.
The box design for all axes is perfect for absorbing vibrations during heavy-duty machining, and the Hwacheon-developed air movement system on the X and Y axes keeps the workpiece stable while cutting objects. heavy load.
The distance between the spindle and the machine body is designed to be short to help the machine operate stably after a long period of operation.
2. High rigidity spindle design
The main shaft integrates the motor to limit vibration, noise and power loss at high rotation speeds.
The oil jet is sprayed directly onto the bearing for effective cooling , and the motor and spindle assembly are cooled by a cover to limit heat- induced displacement .
To achieve greater precision , the spindle continuously monitors possible thermal shifts and makes necessary adjustments in real time.
3. High precision level actuator
The feeding surface is coated with fluorine resin and hand-ground by Hwacheon's master technicians with high precision to minimize friction.
The servo motor is directly coupled to the drive; and the ball screw is preloaded, so the heat generated from the ball screw does not cause deformation and affect machining accuracy.
