Acme screw thread asking for precise movement of the key components in the movement, mainly made of high quality alloy steel processing ABBA trapezoidal screw, after heat treatment, to ensure its excellent mechanical properties, in the manufacturing process, coarse and fine silk trapezoid HIWIN separate process bars, effectively ensuring a reasonable distribution of the stress components, the key process in the heated workshop process, a stable temperature, to ensure that all indicators meet the national standard high-precision screw JB / T 2886-1992 Machine acme screw, nut technical conditions relating to the acceptance criteria . Keystone Ball accuracy class and acceptance criteria: R logo screw, right-handed screw is generally not marked. 7 screw - for precise drive, precision THK trapezoidal screw screw lathe, Exon grinder, surface grinder feed exercise. How it works 1. trapezoidal screw trapezoidal screw is used to rotary motion into linear motion; or linear motion into rotary motion of the actuator, and has high trapezoidal screw drive efficiency, accurate positioning, etc. 2, when the trapezoidal wire When the rod as an active body, with the rotation angle of the screw nut will be in accordance with the corresponding specifications of the lead into linear motion, the workpiece can be connected via a passive holder nut and nut, in order to achieve the corresponding linear motion.
