Acme screw thread is to ask for a key component in the movement trapezoidal screw manufacture precise movement, the main use of high-quality alloy steel processing, heat treatment processing trapezoidal screw price guarantee its excellent mechanical properties, in the manufacturing process, coarse and fine process separate trapezoidal screw, 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 the relevant acceptance criteria. Keystone Ball accuracy class and acceptance criteria: R logo customized trapezoidal screw screw, right-handed screw is generally not marked. 7 screw - for precise drive, precision screw machine tools, Exon grinder, surface grinder feed exercise. Lubrication proposal trapezoidal screw screw on the ladder with oil lubrication, especially sump lubrication or drop lubrication is more effective. Sump lubrication is the most appropriate method, because this method can satisfy severe conditions, such as high speed, heavy duty or external heat transfer, and the ladder screw cooling. Drip lubrication suitable for medium and low speed in light load. Please select lubricants under the conditions shown in Table 2.
