The PINNACLE LH500A horizontal CNC machining center features a high-quality cast iron construction. The headstock's hydraulic counterbalance actuator system ensures maximum vibration damping and minimizes load on the vertical feed servomotor.
The main structural components are made of high-quality cast iron, hardened and tempered. Precision "P" class linear guides utilize rollers instead of traditional balls, significantly increasing their stiffness and load capacity. The headstock's hydraulic counterbalance actuator system ensures maximum vibration damping and minimizes load on the vertical feed servomotor. The column, with its almost oversized strength parameters, ensures maximum rigidity and precision. The spindle features high-precision P4 class bearings and provides a wide machining range and high speed. The spindle's oil cooling circuit prevents thermal expansion and ensures optimal machining conditions. The hydraulic table rotation brake ensures complete rotation locking – maximum rigidity translates into the highest machining precision.
Chip wash system: Coolant nozzles located at the rear of the chute ensure continuous chip removal from the workspace.
Ball screw bearings: A direct connection of a flexible coupling to the ball screw and servo motor ensures excellent dynamic performance and accuracy even at the highest feed rates.
Spindle cooling: An optional through-spindle coolant system with a 20-bar pump and additional coolant tank ensures optimal tool and workpiece cooling even at the highest machining parameters.
40-tool chain magazine: High-capacity, automatic tool magazines ensure fast and precise tool changes without restricting the workspace.
Two screw conveyors: Located at the rear of the machine, these conveyors ensure fast and efficient chip removal. A chain chip conveyor is available as an option.
Automatic lubrication system: Ensures the correct dosage and distribution of lubricant to all points, such as linear guides, ball screws, and bearings.
