Hwacheon Machinery America offers its Hi-Tech Big Bore line of horizontal turning centers designed for machining large oilfield components. The HT-550BB, HT-700BB+ and HT850BB+ feature 7.08", 11.61" and 14.57" through-spindle holes, respectively, and accommodate workpieces ranging to 36" in diameter and 216" in length. Spindle noses range from ASA A2-15 to A2-20, and long-bed versions of the turning centers ranging from 84" to 216" are also available.

The machines feature a 13"-wide turret and boring bar capacity ranging to 31". The Y-axis head with 9" stroke is said to enable multitasking operations with rapid positioning speed of 10 m/min. The machines offer a 20,000-kg clamping force, and heavy-duty bearings in the tailstock are said to promote precision. Quill diameters range from 120 to 160 mm within a rugged built-in quill structure and the steady rest capacity is 20". An air chuck is optionally available.

Integrated bed frames of fine-grain Meehanite castings minimize heat distortion. The solid-box guideways are said to maintain rigidity and precision even during prolonged, heavy operations. A four-speed automatic transmission system enables low-speed, high-torque turning as well as high-speed machining. Precise recuperative cylindrical roller bearings and the multiple thrust angular bearing enable hard turning of tough alloys, the company says. The spindle can be geared down for extra torque, and the machines feature the company’s heavily ribbed torque tube design. The turning centers are controlled by a FANUC 0i with the Manual Guide i dialog-based programming system.

FUJI machines are built for automation from the ground up.
