Used 3M 910 #9219014 for sale

3M 910 Optical Comparator is a specialized device used to analyze the dimensional accuracy and finish of machined parts on production lines. It features a closed-loop feedback system that performs a full range of coordinates, measuring, and inspection-related tasks to enable high-precision part evaluation. The device consists of a robust cast-iron base, a computer-controlled optical readout, and a touch probe. The cast-iron base provides stability and durability to 910 while in operation. It houses the optical components of the comparator and eliminates the need for any performative vibration isolation. Its tables and guides are designed to be magnetically attracted to the base, reducing friction and allowing for smooth movement and accurate measurements. 3M 910 is powered by a computer-controlled optical readout, which is an encoder that reads two-dimensional coordinates. The input-output process is enabled through a precision linear scales that measure X-Y distances with accuracy up to 0.00005 inches. Additionally, the readout is capable of storing a multitude of tolerance information, baseline values, and measurement offsets, allowing the operators to quickly recall such information for increased accuracy and replication of measurements. The touch probe is the primary input device for measuring the dimensional features of a machined part. It is designed to come into contact with the part and transfer such contact force to the readout. The shaft of the probe is machined with high precision, allowing to have readings that have accuracy up to 0.0004 inches. It also features a limit switch protection that ensures normal operations, even while the probe is coming into contact with the part. Finally, 910 features an LED light system that allows the operator to focus on the part in order to measure it accurately. This illumination system eliminates undefined shadows and provides a clear vision of the part for precision measurements. Overall, 3M 910 is a reliable and accurate optical comparator designed for complex part evaluation in production lines. The combination of its robust construction, precision readout, and measuring device provides excellent repeatability and accuracy when measuring machined parts. Therefore, it is an ideal device for increasing the efficiency of machining operations while ensuring the dimensional accuracy of the end-product.
