Heavy-Duty CNC Vertical Turning Lathe Lineup of You Ji
Taiwanese builder You Ji Machine Industrial Co., Ltd. specializes in heavy-duty CNC vertical turning lathes (VTL), vertical turning centers, and portal milling machines.
The machinery is engineered for high-precision machining of massive rotational components across aerospace, energy, and heavy industrial sectors.
The product ecosystem spans agile YV vertical turning centers, high-capacity VTL series with table diameters from 1000 to 8000 mm, rigid GMC gantry milling centers, and high-precision YH horizontal turning lathes with slant bed architecture.
Machine Tool Sizing and Technical Configuration Criteria
Configuring a You Ji machine depends on maximum swing diameter, cutting height, table weight limits, and metal removal rates. For machining turbine rings and large industrial flanges, VTL-1200 and VTL-1600 models provide exceptional rigidity via Meehanite casting beds.
For complex workpiece processing in a single clamping, machines are outfitted with C-axis live tooling spindles and high-capacity automatic tool changers. SpareX provides thorough engineering review of customer drawings, cycle time estimation, and direct equipment delivery.
