12" 36" Linear Scale Digital Readout 2Axis DRO Display Bridgeport 9X42 Table
Introduction:
- Digital display to eliminate backlash and improve precision
 - Advanced trigonometric calculation so to accomplish a perfect project
 - 11.6" wide display to offer excellent long-distance viewing
 - Digital readout kit can avoid wasting weeks checking machine precision
 
Note:
- Purchase Note: 1. This order includes 2 pieces linear scale 12" X 36"(travel length) and 1 piece 2-axis DRO to fit series I Bridgeport with a 9x42 table. It competes for a dro kit with parts for mounting. Digital readout DRO Description; The digital readout(DRO) is a high-precision instrument that can be used on the 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. The actual physical length is 141mm longer than travel. That is the total length=travel length+141mm. One inch equals 25.4mm.
 
Main Features:
- 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 proven to be the most reliable and durable. The main grating adopts a 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, and 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.
