Diamond Machining: Ultraprecision Machine Technology

Although many types of slides offer straightness of 0.5 μm or less, the oil-bearing design provides a high degree of extremely smooth motion. Bearing surfaces should be designed symmetrically to ensure smooth, friction-free motion during the machining cycle, which allows for surface finishes on the order of 1 to 2 nm to be achieved on a

WO1988003237A1 - Rectilinear/rotary motion converter

A device (10) for interconverting rectilinear and rotary motion is designed so as to reduce side thrust exerted on a frame (18, 22) by a slide (12) as the slide reciproes linearly relative to the frame and such rectilinear motion is converted into the rotary motion of a crank (24, 26) or vice versa. More particularly, an elongated opening (46), which receives a crankpin (28) of the …

Benefits of a rotating ball nut (aka driven nut)

Aug 03, 2018· The driven nut’s maximum rotary speed (n max) can be determined from the characteristic speed, or DN value. (Note that the published maximum speed may be lower, due to limits imposed by the radial support bearing or by other ball nut design factors.) DN = characteristic speed (mm/min) n max = maximum rotary speed (rpm)

Needle roller bearing - WikiMili, The Best Wikipedia Reader

Nov 19, 2020· A bearing is a machine element that constrains relative motion to only the desired motion, and reduces friction between moving parts. The design of the bearing may, for example, provide for free linear movement of the moving part or for free rotation around a fixed axis; or, it may prevent a motion by controlling the vectors of normal forces that bear on the moving parts.
