摘要： PURPOSE: To improve the form accuracy of a scroll by measuring the thermal deformation of a scroll working device and correcting the same. CONSTITUTION: Thermal deformation of a scroll working device used in working a scroll lap part is measured as follows. The position of a tool 2, that is, the relative displacement of the tool 2 to a table is measured by laser beams Lx, Ly, Lz of a measuring instrument (e.g. non-contact optical displacement meter) near the table on a column where a rotary table is mounted. Thus, in the scroll working device, thermal deformation of the column which is hard to be estimated can be corrected, so that the form of a scroll lap can be always worked with a high accuracy regardless of the working time of the scroll working device and the outside air temperature.

摘要： PURPOSE:To provide an efficient and high-precise fixe scroll which is constituted to eliminate high-precise machining of a functionally unnecessary part and to provide a machining method thereof. CONSTITUTION:A machining method for a fixed scroll comprises a first process wherein a spiral lap 1d is finished in such a state to grasp a rough machining part, such as the outer surface 1f and the flange surface 1g of a fixed scroll 1; a second process wherein a grinding work is applied on the outer peripheral surface la, the end plate surface lb, and the addendum surface 1c of the fixed scroll in such a state to grasp the scroll by means of a chuck and the end plate surface 1b is formed in such a state to be recessed from the outer peripheral surface 1a and the addendum surface 1c and a polishing work is applied on the outer peripheral surface 1a, the end plate surface 1b, and the addendum surface 1c after the second process; and a third process wherein a polishing work is then finished in such a state that the grinding grain mark of the polishing work remains on the end plate surface 1b. In the polishing method, the outer peripheral surface 1a, the end plate surface 1b, and the addendum surface 1c are brought into contact with a rotating disc-form grinding wheel and a pressure and polishing are applied by a pressure plate 7 of universal coupling structure from a direction opposite to that of the end plate surface 1b as the fixed scroll 1 is rotated and oscillated.

摘要： PROBLEM TO BE SOLVED: To accurately judge the thickness of a scroll lap by extracting not only a deviation on a shape but also a deviation on a dimension, and to adjust a working device on abrasion of a tool by collectively converting a measuring coordinate point sequence of an outer line and an inner line into coordinates. SOLUTION: When abrasion of a tool used for work proceeds, a diameter of the tool reduces, causing a scroll lap becoming thick, reduction in a radius of the tool can be seized as an average of a thickness deviation. An average ΔT of this thickness deviation is determined by expressions I to III, and is set as an average thickness. Data on the tool diameter of a working device or data on a tool offset or data on a tool locus is corrected in the direction for eliminating the average thickness ΔT. ΔSm' and ΔUi' are a deviation ΔSm' and ΔUi' of a measuring coordinate point and a design value, respectively.
