Only with Acu-Rite's precision glass scale technology can you be assured that the encoder on your machine tool is checking its actual position thousands of times in every inch of travel.

An Acu-Rite 1um precision glass scale has 1,270 accurately placed chrome lines per inch, each of which a photoelectric reading head detects as it slides across the glass.

This give Acu-Rite's precision glass scales a fundamental measuring interval 10 times finer than the nearest alternative encoder technology.



Acu-Rite's precision glass scales and encoder optics are enclosed in an aluminum housing with sealed, die-cast metal end caps which make them virtually unbreakable during standard machine tool usage.

To enhance system durability, the glass scale and sensor are protected from the environment by a recessed, highly chemical-resistant, interlocking lipseal to further prevent the entry of metal chips and other contaminants. A nickel-plated armor cable offers additional protection and allows for a tighter bend radius. Acu-Rite also applies a conformal coating that seals the wires and circuitry inside the reading head, leaving little chance of failure.

Acu-Rite bases their scales size on reading length, not overall length. 

To get the correct size scale, you need to measure the overall length of the scale and then subtract 6". For example, on your 48" Bridgeport, your scales' overall length is going to be 41" so to get the proper scale you will subtract 6" and order the 35" scale. 

This will not work if you have an Acu-Rite MillPWR, please call the number below for pricing
