VESTA-660

SUPER FAST ROUGHING AND ULTRA PRECISE FINISHING PERFORMANCE

These high-performance machines are optimized for job shop machining applications, with the easy-to-use interface to maximize your productivity.
HTLD increases the life of your tools; HECC provides perfect contour control for better machining efficiency; OPTIMA controls the feedrate and HTLD adjusts the temperature in real time. To minimize thermal displacement and to increase the life of the spindle assembly, the spindle unit is grease-lubricated and jacket cooled. The advanced feed drive complements the spindle for highly precise machining result every time.

The super tough roller guide keeps its precision even at high speeds, and offers a variety of options for your convenience. Last but not least, VESTA's advanced chip removal and lube separation system help to save cost.

Main features

High-Rigidity Mechanical Structure

The super rigid C-type machine structure, designed with the help from finite element analysis, minimizes any distortion which may occur from changes in machining environment and condition. All axes integrate Roller LM Guide for fast and stable feed.

High-Performance Spindle

The high-performance spindle is integrated directly into the motor for stable, high-speed cutting, getting the power and torque directly from the motor without the power loss. The spindle is grease-lubricated and jacket cooled to minimize the thermal displacement and to increase the life of the spindle assembly; and the air curtain design prevents any foreign substances from entering.

High-Performance Feed System

Each axis is equipped with the top-of-the-class Roller LM Guide, and the linear guide and the ball screws are automatically lubricated for rapid, precision feed.

Mounting software

Hwacheon Tool Load Detect System

"Detect and diagnose the most minute of tool-end point movement"

HTLD constantly monitors the tool wear to prevent accidents, which may occur from a damaged tool and help to stop tool wear from deteriorating the workpiece.

(The load is measured every 8 msec to ensure accuracy.)

Hwacheon High Efficiency Contour Control System

"Roughing quickly, finishing is precisely"

HECC offers an easy to use programming interface for different workpieces and different processing modes.

The system provides a precise,custom contour control for the selected workpiece, while prolonging the life of the machine and decreasing process time. The customizable display provides real-time monitoring and quick access.

Cutting Feed Optimization System

"Maximize your productivity with intelligent system"

OPTIMA utilizes an adaptive control method to regulate the feed rate in real time, to sustain the cutting load during a machining process. As a result the tools are less prone to damage and the machining time is optimized.

Hwacheon Spindle Displacement Control System

"Real-time correction for the displacement in the spindle"

When the spindle rotates at high speed, the centrifugal force drives the taper to expand, causing errors in Z axis. HSDC constantly monitors the temperature at each spindle region and makes optimal prediction for thermal displacement.

The system then makes necessary adjustments and eff ectively minimizing thermal displacement.

Hwacheon Frame Displacement Control System

“System for maintaining processing accuracy for a long period of machining"

HFDC is equipped with highly sensitive thermal sensors in the casting region where thermal activity is suspected; monitoring and correcting displacement.
