DEVICE FOR FIXING MATERIAL FOR PROCESSING SCROLL AND METHOD FOR PROCESSING SCROLL

摘要

PURPOSE: A fixing device for material for processing a scroll and a scroll processing method are provided to improve the accuracy and performance of the scroll by indirectly fixing a material to be processed on a jaw through a jig and minimizing the deformation of a disc to be processed by the pressure of the jaw. CONSTITUTION: Plural holes corresponding to a through hole of a jig(30) are processed on one side of a material to be processed into specific depth. The through hole of the jig and the hole of the material are equalized and the material is fixed on the jig by connecting a bolt from the through hole. The jig is arranged between the plural jaws(20) installed on a chuck(10) to be movable. The position of the jig is fixed by moving the jaw to pressurize the jig. The chuck is rotated at a high speed and a tap is adhered to one side face of the material so that the material is processed. Thus, as the material to be processed as a scroll is not deformed, the accuracy and performance of the scroll are improved.
