100% Satisfaction Satisfaction Guaranteed. DRO 3 Axis Digital Readout Display +3Pc Glass Linear Scale for CNC Mill Lathe Machine (450Mm+500Mm+1000Mm). Weight: 5.0 kg. HIGH PERFORMANCE? 3Axis Digital Readout DRO Display 5um, Available Travel Length:450mm+500mm+1000mm(18″+20″+40). Note: The Total Length =Travel Length+140mm=590mm+640mm+1140mm. HIGH PRECISE? Glass precision Metrology Grating, Resolution 5um, Accuracy ±5um/ 0.0002 (at 20 deg C);Pulse signal period 20um, Travelling Speed 100m/min, 8 bit LED High-definition nixie tube. IDEAL PROFESSIONAL CHOICE? This is a complete kit. WIDE APPLICATION? Applicable for milling machine, drilling machine, grinding machine, lathes, profile projector, video measuring machine, position monitoring, coordinate measurement, X-Y-Z working table monitor, mechanical control as well as other area of linear scale and rotary encoder. You will receive 2 separate packages due to the different dimensions of scales and display if you only receive one of them, the other one is maybe on the way to you. Please just wait for a while. DRO is designed to match multi kinds of linear scale with resolution 0.05µm, 0.1µm, 0.2µm, 0.5µm, 1µm, 2µm, 5µm, 10µm, 20µm or 50µm. The DRO resolution must be set to completely match the linear scale precision. (This kit default is 5um/0.005mm/0.0002 resolution). Readout only allows TTL square wave signal input through 9 pins connector, which completely matches the linear scale encoder. Pin 1 to 4 connects +5V, 0V, A, B, and the pin 5-9 are blank. Robust casing, high reliability and durability switch design. Full-closed design ensures its clean and dust resistance, safety increased. Having a good capacity of resisting disturbance, durable keyboard, easy to change. LINERA SCALE with 3 METER CABLE. Signal cable uses multilayer shielded wire steel and metal shell to provide extra protection. Deafult offer 3 meters (9.84feet long) cable connecting with linear scale. Full set of installation accessories (L type cover, backplate and screws) included, each scale equipped with some extra screws to avoid unsccessful installation. Widely used for manual machine, such as milling machine (for Bridgeport Mill, Knee Mill, Rong Fu 31 mill / drill, Grizzly Mill, etc), drilling machine, grinding machine, lathe, EDM, linear cutting machines etc. Tool diameter compensation function. Radius diametr, mm/inch function etc. 1pc 3Axis DRO Digital Readout. 3pc Linear Scale (upon your choice). 1pc English User Manual. 4pc L type Mounting Plate. 1 full set Installation screws.
