Heavy-Duty Vertical Turning Centers
May 1, 2020
The Yama Seiki-Goodway GV-1 Series features advanced composition and core elements designed to provide high rigidity and heavy-duty cutting capabilities needed for heavy workpieces and tough materials. GV-1 series optional live tooling spindle and C-axis can provide turning, milling, drilling, tapping and other complex processing capacity. This can increase production efficiency and avoid setting errors when parts move between machines.
"The Finite Element Analysis (FEA) of the GV-1 series provides optimal machine design and a lightweight structure while ensuring machine rigidity," said a company spokesperson. "The rigid bed and column are of MEEHANITE casting that is capable of withstanding much greater stress without deforming and provides maximum vibration dampening. Contact surfaces of all slides, bed and column are precision hand scraped to provide maximum assembly precision, structural rigidity and load distribution."
The crossrail is mounted with four sets of up/down positioning mechanisms, providing strong locking positioning at each point, which strengthens the overall rigidity of the crossrail and tooling spindle and provides high accuracy. The rigid crossrail is designed with a box-shaped structure to prevent thermal displacement and provide machine stability during turning operations.
W-axis travel is up to 800 mm for better machining flexibility. Pretension on all ground ball screws with extra wide ground box ways provide high rigidity for heavy-duty cutting. Crossrail can be moved up and down as desired to meet customer requirements, while the column features a high-low box way design to firmly support the crossrail to minimize structural distortion.
Instead of using partial belts, the GV-1 series uses all gears to connect the spindle motor and work table. The high torque workpiece spindle is equipped with a FANUC 45 kW spindle motor that delivers a maximum torque output of 23,900 Nm at 18 RPM, suitable for heavy-duty cutting conditions. The CF-axis is driven by a high resolution servo motor. It is adopted with a worm gear drive system for high accuracy transmission and easy backlash adjustment. The indexing accuracy is up to 0.001°. Working with the live tooling turret, the CF-axis and disk brake system enable the machine to perform multiple tasks, such as drilling, tapping and milling operations, including cylindrical and polar coordinate interpolations.
