Heavy Duty Performance VTC

“The YAMA SEIKI-GOODWAY GV-1600M vertical turning centers combine power, strong construction and heavy duty cutting capabilities for the ultimate machining power,” said a company spokesperson. “These maximum performance machines will accomplish demanding turning applications.” With GV-1600M’s maximum turning diameter up to 1,800 mm, maximum weight load up to 8,000 kg and available live tooling spindle and CF-axis capabilities, turning, milling, contour milling and drilling applications may be completed in one single machine.

“YAMA SEIKI-GOODWAY GV-1600M is built to endure years of rigorous high production turning; the heavily ribbed, thermally balance, high-rigidity bed and column are of Meehanite casting,” said a company spokesperson. “It is capable of withstanding stress without deforming, and it provides maximum vibration dampening.” By using Finite Element Methods (FEM), optimal reinforced ribbings are directly cast into the bed and column structure. “Mechanical rigidity has been increased by more than 30% when compared to conventional designs. YAMA SEIKI-GOODWAY GV- 1600M is capable of performing heavyduty turning and maintains long-term super high-precision accuracy,” said the spokesperson. More rigidity also means extended tool life. The contact surfaces of all slides, spindles and ball screw bearing housings with the machine bed 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. The crossrail is designed with box-shaped structure to prevent thermal displacement and assure machine stability during turning operations. The W-axis travel is up to 800 mm for machining flexibility. Space between each step of the positioning mechanism is 200 mm. Pretension on all ground ball screws with extra wide ground box ways provide rigidity for heavy-duty cutting. The crossrail can be moved up and down as desired to meet requirements while the column is designed with the high-low box way design to firmly support the crossrail and minimize structural distortion. The square ram on the tooling spindle has a closed-type design and is fixed with four sets of powerful wedges.

Instead of using partial belts, YAMA SEIKI-GOODWAY’s GV-1600M uses all gears to connect the spindle motor and work table. With the standard high-speed ratio, the high-torque 2 - speed gear boxmated with a 40/6,000i series spindle motor provides more output for heavy duty cutting. “The optional Cf-axis and disk brake system available on the GV- 1600M provide the most rigid and powerful type of C-axis on the market today,” said the spokesperson. “It is designed 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 enables the machine to perform multiple tasks, such as drilling, tapping and milling operations, including cylindrical and polar coordinate interpolations.

“YAMA SEIKI-GOODWAY’s GV- 1600M has overall high-rigid vertical turning center construction which can overcome horizontal turning centers’ problems when machining large diameter, heavy weighted and none symmetrical workpieces,” said the spokesperson.
