SIRIUS-1250/1750/2500 with Bridge Type Design

SIRIUS-1250/1750/2500 are large bridge-type vertical machining centers with precision feed drive and high-performance spindle. These machining centers provide a total solution from tool selection to product completion-making them ideal for your extra-size mold applications where quality is essential.

Hwacheon’s extra-size bridge type vertical machining centers guarantee to enhance the quality of your large mold applications, such as large display frame, automotive and aerospace parts.

The SIRIUS series of large size vertical machining centers use powerful built-in motor spindles and high-speed, high precision milling heads complemented by Hwacheon’s proprietary Oil-Jet cooling system to guarantee consistent strong roughing performance and provide high quality product result hours after hours of high speed machining. Each SIRIUS vertical center is designed using 3D simulation FEM analysis to achieve structural rigidity which can translate to quality product results; while the Hwacheon designed machining software components enhance safety and work efficiency in your factory. The machines are configurable with many different options so that they can integrate perfectly to your work environment and application.

Symmetrical Portal Structure for Extra Stability

The symmetrical portal structure is the ideal design for distributing vibration, the upper weight, and the heat evenly throughout the entire frame. This characteristic is the base for the machine to maintain its feed precision even after hours of continuous machining; the distance between the Y-axis and the contact point of the tool has been minimized to enhance the overall rigidity and machining precision.

Integrated Motor Spindle

In Hwacheon temperature controlled clean room facilities, where this Super Precision High Speed Spindles are assembled, only the most experienced and skilled engineers are allowed to produce at highest industry and quality standards a spindle worth to be named Made by Hwacheon.

Oil-Jet Cooling

The Oil-Jet cooling and the Jacket Cooling designs have been perfected by Hwacheon’s experience and know how in building high quality spindles. These unique yet highly effective cooling systems minimize the thermal displacement during prolonged machine operations.

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.
