Pinnacle Machine Tool Co, Ltd, has two types of horizontal machining centres that are made using a optimal structural design however one is equipped with a rotary table while other is equipped with automatic pallet changer and a rotary table. The machines major structural parts are manufactured form Meehanite cast iron, hardened to hardness over HB190 and they are tempered for stress relief that ensures deformation-free performance year after year. With the adaptation of an oversized fixed column structure it dramatically increases machining stability. It’s X, Y, Z axis are mounted with roller type linear ways, exhibiting extra high rigidity and loading capacity. Rotary table employs three piece teeth plate for high accuracy indexing and combined with hydraulic locking mechanism allows full teeth engagement. This results in higher rigidity and increased heavy cutting capacity. While the automatic pallet changer is swing type based and features stable construction and smooth change motion. The pallet change is fast accomplished in only 8 seconds. Position of pallet on oversized cones guarantee high positioning accuracy and has a maximum loading capacity of 400kg. With the installation of a gear box, the spindle provides two speed changes. The low speed range is 40~1750rpm, and high speed range is 1751~8000 rpm. The wide speed range permits the machine to perform heavy cutting and fine finishing. All of the gears and bearings in the gear box are oil-bath lubricated. The running of the spindle is transmitted through a gear box, making the machine excellent for heavy cutting applications. There are two screw type chip conveyors provided at right and left side of the machines base. During cutting, the chips are delivered through these chip conveyors for exhausting chips outside of the machine.
