A valve body processing apparatus of the load sensing pressure reducing valve is provided to shorten the processing time and reduce machinery and work force used in the machining process. A valve body processing apparatus comprises a 3 stage tool for rough machining which rough-machines a second compression chamber(16b), a third compression chamber(16c) and a fourth compression chamber(16d); a 5 stage tool for rough machining a first compression chamber(16a) or the fourth compression chamber(16d); the 3 stage for rough machining where a chuck assembly part fitted to an additional drilling machine chuck is formed on the rear part; and a 3 stage tool for finish cutting for machining precisely the first compression chamber or the third compression chamber corresponding to piston sliding region inside the compression chamber(16). |
