High accuracy rotary table for circular component inspection


Supplier of precision positioning devices for rotary and angular inspection systems RPI UK is launching a new TruMotion system next month

Jim Palmer, RPI’s sales manager, said, “TruMotion is our latest innovation in the measurement of circular geometry for internal and external diameters and faces of small and medium sized round parts in shop floor machining and grinding applications such as gears, gauges, bearings and aero engine components.  Not only does it provide a solution to market requirement, but delivers a high specification offer at a very competitive price.”

The TruMotion range of precision, manual spin, mechanical bearing rotary tables is designed to inspect circular components in a shop floor environment, whilst maintaining world class accuracies more commonly seen in the standards laboratory. The inspection system will be available in two sizes (200mm and 400mm) with a maximum load capacity of 50kgs, offering radial and axial runout targeted at 3 microns. Its user-friendly interface with an optional touch screen display also offers single or double channel data capture.

The TruMotion will be launched at Quality Show 2019 in Rosemont, Illinois on October 22, 2019. Also being demonstrated at the show will be QuadProfile, a brand-new capability to the CMM market for 2019, as the smallest and most accurate rotary table for turbine blade inspection. The new addition to RPI’s Quadrant range, further enhances the product portfolio enabling the ultimate in low profile and compact rotary table design for the CMM market.

The Quadrant range of rotary tables provide an additional axis for any high precision CMM (Coordinate Measuring Machine) inspecting component parts such as gas turbine discs and fan blades. The part is simply rotated to meet the CMM’s measurement probe rather than the three-axis probe being programmed to reach multiple measurement points around a part.

This simplifies the measurement procedure, helping to deliver fast and accurate indexing as well as increase the CMM’s application range and effective measuring volume. Overall, this improves the flexibility, productivity and efficiency of the CMM inspection. RPI have more than 750 successful CMM rotary table installations worldwide.
