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 trapezoidal screw material in the manufacturing process, separate coarse and fine process, effectively ensuring Parts of reasonable stress distribution, the key process in the heated workshop processing, stable temperature trapezoidal screw material, 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 screw lathes, grinders trapezoidal screw exon sample surface grinder feed exercise. How to extend the life of the trapezoidal screw trapezoidal screw due to the use of the sliding surface at runtime to support the load, it will produce the phenomenon of friction and heat, the process, there will be some of the sliding surface wear. PV curves define the safe operation of the limit load and speed. When the load is increased, the rotational speed must be reduced to prevent overheating and wear; and vice versa. Thus, when the load is small can realize a high screw rotation speed trapezoidal screw, while the load is large, the screw need to run slowly. It should be noted that, without increasing the rotational speed of the premise, by increasing the screw lead screw to increase the linear speed. This method can be used to prolong the life of Buying trapezoidal screw screw, acme screw, Korea and Taiwan transmission machinery provided by the Dongguan City, Transmission Machinery Co., Korea and Taiwan.
