G11A Horizontal Boring and Milling Center Advances Heavyduty Precision Manufacturing

The machine uses resin sand castings for the main body, a construction intended to provide high rigidity. For key components such as the RAM and RAM seat, ductile iron is used to improve vibration damping and structural stability during cutting.

The working envelope covers X/Y/Z travels of 1,600 × 1,400 × 1,400 mm, with a 600 mm W-axis travel. The configuration is designed to accommodate large and complex workpieces, including operations that require extended reach along the ram axis.

To maintain positioning accuracy over long production cycles, the G11A uses internationally sourced components in its core transmission chain. The design combines ball screws, guideways, bearings and lubrication systems selected for durability and response.

• Transmission system: German IF ball screws are used for positioning accuracy and response across long travels.
• Guide system: German INA guide roller units are paired with Turcite-B wear-resistant material on sliding surfaces to reduce friction loss.
• Bearing configuration: SKF spindle bearings are used, while screw support bearings are supplied by NSK or FAG for stability at high speeds.
• Hydraulic and lubrication: A Japanese Youyan hydraulic station and HERG/Byjur centralized lubrication system are integrated to support sustained lubrication of moving parts.

The table shows key specifications for the G11A, including travels, table capacity, spindle speed, motor power and torque. These figures define the machine's basic working range and load capacity for heavy-part machining.

The table size is 1,400 × 1,250 mm and the maximum load is 5,000 kg. The spindle runs at up to 2,500 rpm and is driven by a 17 kW motor, with maximum spindle torque listed at 1,450 Nm.

The G11A can be specified with a range of optional milling heads, including face milling, right-angle, universal and extended heads. These options allow the machine to be matched to different workpiece geometries and machining positions.

For special requirements, the machine can also be configured with a raised column or extended bed. Such options are intended to adapt the working envelope to workpieces that fall outside the standard configuration.
