Static pressing slideway is what is reached static the working principle that presses slideway

0005) ; The motion of slideway does not accept the restriction of load and speed, and the shift when low speed is even, without creeping phenomenon; Because the liquid is had,suck display vigour to use, consequently of slideway fight brace up the gender is good; Carrying capacity is big, rigid good; Attrition is calorific small, slideway temperature rise is small. But the liquid is static the construction that controls slideway is complex, much system of a hydraulic pressure; Cost is high; Oily film ply keeps constant and changeless hard. Reason liquid is static press slideway to basically be used on machine tool of large, heavy-duty numerical control. The liquid is static the structural type that presses slideway can be divided to leave type is mixed shut type two kinds. Static to shutting type liquid press slideway, all leave on each directional slideway faces of its slideway have oil pocket, shut type slideway to have so bear the ability of each direction load, and its slideway poises the gender is better. Static press slideway working principle and static pressure bearing is identical. the lubricating oil that has constant pressure, classics restrictor inputs the oil pocket to slideway face, can form bear the weight of oily film, make condition of pure liquid attrition is in between slideway face. Advantage: The change of slideway motion speed is very little to the influence of oily film ply; The change of load is very little to the influence of oily film ply; Liquid rub sassafras, rub sassafras coefficient is only 0.

005 the left and right sides, oily film is fought brace up the gender is good. Defect: Static control slideway oneself construction more complex; Need adds a system that offer oil; Very tall to the clean degree requirement of lube. Main application: The feed motion of accurate machine tool and slideway of low speed motion CNC Milling CNC Machining
