Acme screw thread is to ask for a key component in the movement precise movement, the main use of high-quality alloy steel processing, heat treatment process to ensure its excellent mechanical properties, in the manufacturing process, separate coarse and fine process, effectively ensuring stress components reasonable distribution of the key processes in the heated workshop processing, stable temperature Buying trapezoidal screw, to ensure that all indicators meet the national standard high-precision screw JB / T 2886-1992 Machine acme screw, nut technical conditions related 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 screw machine tools, Exon grinder, surface grinder feed exercise. Screw has an important performance and value trapezoidal screw material consumption and use, and can be expressed in the use of a good advantage, but also in the use of certain amount of defects, must be timely disposal of consumer and design and improvement to ensure a serious role and value in use in practice. 1, in accordance with the national standard GB / T17587.3-1998 and application examples of ordinary trapezoidal screw, ball screw (now simply replace the trapezoidal screw, lead screw has been commonly known) is used to rotary motion into linear motion; or straight motion into rotary motion of the actuator trapezoidal screw, and has a high transmission efficiency, precise positioning and other characteristics. 2, when the screw as the active substance, the nut will be in accordance with the rotation angle of the screw corresponding to the specifications of the lead into linear motion, can be started after the nut member and the nut seat convergence, thereby completing the corresponding linear motion. 3, ball screw nut because there was no gap between when high precision linear motion, especially when frequent commutation without backlash compensation. Friction between the ball screw nut is very small, very easy rotation.
