cnc lathe machining center J46MY,J52MY,J76MY (Virtual Y-type high-speed direct driving turret machine tool)

Main performance
• Swing over lathe diameter 700mm
• Max. turning length 480mm
• Taiwan SYNTEC controller
• Under the same conditions of configuration, casting structure, casting aging, assembly precision, etc.
• The interpolation Y is more rigid than the perpendicular Y
• The roundness of interpolated Y is easier to adjust than that of perpendicular Y
• The stroke of vertical Y is easier to lengthen than that of interpolation Y
• Vertical Y-axis machining produces better surface finish than interpolated Y-axis machining

Main performance

• Programming vertical Y is easier than programming interpolated Y
• The 0° power head can reach 8000 RPM under normal use, and the 90° power head can reach 6500 RPM under normal use
• The gearless module transmission within the turret eliminates the heat source and ensures machining accuracy
• The milling and turning function can process complex materials such as stainless steel, titanium alloy, and carbon steel
• Chip removal method: Side chip removal and rear chip removal are integrated, allowing for arbitrary installation
• The integral casting undergoes aging processes such as annealing and vibration to ensure long-term stability during machining and extend the service life of the machine tool
