High Accuracy - Three pieces hirth coupling gear: The Internal indexer table comprises three pieces Hirth Coupling Gear to perform indexing and positioning. Indexing accuracy up to ±4 arc seconds or less. Repeatability of ±1 arc second more or less. Able to maintain its high precision after long period of use. Heavy Duty Cutting Toleration - Three pieces hirth coupling gear clamping system: Indexing table built with three pieces of Hirth Coupling Gear, rotation disc does not float during degree indexing. Fenxie and cutting fluid will not seeps into the solidly sealed structure body unit. Superb rigidity clamping force deliver great effect during heavy cutting.Stable and Safe - Highly sensitive confirmation structure: Hydraulic driven and high sensitive proximity switches to execute release confirmation, rotation and homing, ensuring stable and safety operation. Partition table is dedicated to Heart Indexing Work and automatic switching station of machine tool.Movement - Structure of the Three Pieces Hirth Coupling Gear.The Three Pieces Hirth Coupling Gear units comsist of three parts:A. Coupling teeth (lock to the structure of the rotation disc) B. Coupling teeth (lock to the base structure of the index table)C. Coupling teeth (vertical movement pallet) The index table will is in unclamping condition during Hirth Coupling Gear C descends, Coupling Gear A is tightly supported by structure, disc rotating smooth and accurately without any vertical moving movement. When Gear A completed indexing work, Coupling Gear C move up to match Coupling Gear A and B, clamped the index table. Coupling Gear C perfectly matching Coupling Gear plate A and B. The 30 degree angle pressure of of each gear accurately matches Coupling Gear plate A and B, able to maintain high precision after long period of use.Our single tooth worm wheel manufacturing techniques delivers high precision quality, outruns other conventional multi-toothed machine.Material of the Worm Wheel: ALBC4 grade, HRB180 hardness, durable and postponing possible backlash occurrences.Inspection: Production is inspected by HEIDENHAIN automatic measuring device with report printing.
