Which precision parts need to measure the length and diameter in batches (the accuracy is controlled at um level)?

Refrigeration specialty automatically classifies and groups the diameter, length and size values of high-precision needle rollers, needle rollers and rollers. It has the characteristics of high precision, stable performance, fast sorting speed and stable sorting performance, which is 2-3 times that of domestic general models. It has the advantages of small volume, simple operation and convenient maintenance. At the same time, the environmental requirements are low. It does not need compressed air and is easy to install. Single-phase power supply is 220V, and the power consumption is only equivalent to that of ordinary 40W fluorescent lamp. In recent years, our products have been exported to Suzhou Xinhao Bearing Factory, Zhenjiang Bearing Factory, Changshu Bearing Factory, Shanghai Needle Bearing Factory and Shanghai Nanhui Bearing Factory. Basic technical specifications: sorting accuracy: 0.5um/ 1um/2um (the electronic file can be adjusted in three gears, and the accuracy can be customized as required); Sorting speed: 150-300 pieces/5-65438+100000 spherical rollers per shift (8 hours) Measuring range: needle roller ~ 1.5 mm ~ 6.35 mm Length: 4mm~35mm roller ~ 5 mm ~/kloc-0 24-hour grouping interval: 0.5 μ m -2.0 μ m (adjustable) grouping number: 3- 17 groups (customized according to requirements) power supply/energy consumption: 220V/40W Suitable for the length or length of workpieces: steel balls, rollers, needle rollers, tapered rollers, drum rollers, slender shafts, piston pins, precision drills and other small mechanical precision parts. cut down on
