Product Feature

  • Succeeded in localization (only company in Korea to succeed)
  • Manufactured through the five-axis CNC Tool Measuring Machining manufacturing process using the ultra-precision dimension measuring machine (Zoller)
  • An ultra-precision tool produced by 5-axis CNC Tool Grinding Machining and ANCA

 

Power Plant Machining Tool
The slot part of the turbine rotor requires an ultra-precise dimensional tolerance between pitches (under 5μ) to prevent vibration during fast-speed rotation. Also, in order to prevent vibration during high-speed rotation after assembling the blade, the dimensional tolerance of the dovetail slot part must be under 2.5μ between pitches.

The turbine blade consists of a diaphragm -which transforms the high-temperature steam from the boiler or the nuclear reactor into energy- and a bucket –which transform the energy into work-, this pair is called as the ‘stage’ of the steam turbine. The nozzle and the moving blade works as a driveshaft that rotates the turbine rotor to generate energy.

The Form Tool & Taper Ball End Mill, manufactured by Sungsan Tools, is a carbide tool which requires an ultra-precise dimensional tolerance for the machining of the dovetail of moving blades and vane parts. If the moving blade is assembled and vibration occurs during high-speed rotation, the performance of the turbine drops drastically, so there is no room for any mistakes.
