Precision field amplifier shell drilling and grinding machine

Concentration means that attention can be focused on an object for a long time without relaxation or distraction. It can be used as a test and training instrument for the casting force of aluminum alloy box with visual kinesthetic coordination energy. The instrument consists of a turntable with different test boards and a control, timing and counting system. When the turntable rotates, the transparent pattern of the test board produces moving spot, and the test rod is used to track the spot. The ability of attention concentration is different, which can be reflected in the correct tracking time and the number of die casting aluminum alloy shell. Repeatability spectral reflectance: MAV / SCI, standard deviation is less than 0.1% (400 ~ 700nm: less than 0.2%); chromaticity value: MAV / SCI, δ e × AB is less than 0.04 (after correction, the average value of white board is measured 30 times every 5 seconds). The measurement method is single measurement, average measurement (2 ~ 99 times), repeatability standard deviation is within 0.1% (400 ~ 700nm: within 0.2%); chromaticity value: MAV / SCI, δ e × AB is within 0.04 (after correction, measure every 5S) The measurement method is single measurement and average measurement (2 ~ 99 times). It can be used for drilling, milling, grinding and long-time grinding, with high concentricity accuracy (up to 3 / 100 mm), steel grinding spindle with precision ball bearing and quick tool change locking button. Quiet, 100W high power motor, electronic speed 5000 and 20000 rpm. Streamlined aluminum die casting shaft head ensures the stability of the bearing housing and. No discount on quality: insulation grade 2. Die casting aluminum shell manufacturers 34 tools for industrial quality, all shaft diameter is 2.35mm. Equipped with six 1.0-3.2 mm three channel steel collets (run out 0.03 mm).
