Complete 2 Axis DRO Digital Readout with 12″ & 36″ Linear scales for 9″ X 42″ Bridgeport Milling machine Pictures Description This kit includes 2 pieces linear scale 12″ X 36″ (travel length) and 1 pieces 2 axis DRO, 5μm (0.0002″) resolution (at 45ºC) to fit to fit series I Bridgeport with 9×42 table. It is compete dro kits with parts for mounting. The digital readout(DRO) is a high precision instrument that can be used on lathe,grinding machine,milling machine,boring machine and EMD to make the position detection Scale length refers to the real travel of the linear scale. Actual physical length is 141mm longer than travel. That is total length=travel length+141mm. One-inch equals to 25.4mm. Please check carefully which scales sizes is you need. Introduction:●Digital display to eliminate backlash and improve precision ●Advanced trigonometric calculation so to accomplish a perfect project●11.6-Inch Wide display to offer excellent long-distance viewing ●Digital readout kit can avoid wasting weeks to check machine precision ● Application: lathe, grinding machine, milling machine, boring machine and EMD TO make the position detection. ● The sliding part adopts the five-bearing system which has been proved to be the most reliable and durable. The main grating adopts 90-degree assembly, which is more accurate and accurate. ● The repeatability of the measurement is more stable.● The signal line adopts multi-layer isolation steel and metal soft shell protection, waterproof and anti-interference fine. ● Ruler body with aluminum die-casting, hard chrome plating, corrosion-resistant.● Dust bar with special plastic, corrosion resistance, scratch resistance, friction resistance. ● Parts individual, installation, maintenance, easy maintenance, waterproof, dust-proof good, long service life. ● The sensor uses a glass precision metrology grating as the measurement reference. ● Multi-function, easy to operate, reliable and durable, so that the necessary processing of mechanical products.
