Abstract: in order to improve the quality of the igh cutting hydraulicpowered suppor structure and the mechanical processin parts as well as the mechanics performances and serice lifeofthe whnole machine assembled, improvements were conducted on the manufacturing techique of the avilable hydrauli powered supportsBased on the ZY15000 / 29 / 63 mode high cutng hydraulic powered support as the study objec.the paper analzed the shortages of the automatie conrol and real time monitoring and measuring in the produ ction and manufacturing fechniques of the available hydraui: powered supors.Therefore,the materal selecion of the stoucture parts autonaticful plate cuting advanced beveling machining and welding techrique thelarge diameter leg eyider piston and other machined parts processing te:hique as well as the assembling and inspecion fest fechmique were raioall set up.The stuty showed that the steel plate whally shot blastin .rll stel plate stock cuting welding realtime merntioring and measuring.th procssing before and aiter the welding and other method detemined could fctively improve the performancesof the structure parts The scraping and tumbling compostie processing method could obiously improve the cyinder processing acuracy and the pressurized poweredsupport test technology of the prototype would promote the optimization of product design.
