The new Equator 500 gauging system has been introduced by Renishaw.

Both Equator 300 and 500 systems, while maintaining high levels of repeatability, are capable of rapid scans and high speed touch points on a wide variety of features. Years of customer experience with Equator systems have proven the capability to gauge size, position and geometry on a single device. This can eliminate the need to stabilize parts to the temperature of the quality room prior to measuring geometry and form of critical features.
Climatic conditions can result in variable daily and seasonal temperature cycles. For example, early in the morning a cold machine shop can increase in temperature due to both external conditions and machinery heating up. The system has been proven to cope with this by re-mastering – meaning that accurate gauging can start as soon as the first part has been produced and continue regardless of how conditions change.
The Equator 500 has a gauging volume of 20” diameter in the X/Y plane and 10” in Z when used with the SM25-2 scanning module. This can be expanded to 16” in Z with the SM25-3 scanning module, which allows styli up to 8” in length to reach many more features. The base of the Equator 500 supports workpiece and fixturing with a total weight limit of 221 lbs. The ratio of gauging volume to footprint means that the machine is extremely space efficient, with a footprint of just 36.2” by 36.4”. This allows manufacturers of larger parts to easily fit the Equator 500 onto the shop floor alongside their production machines. Typical applications include the manufacture of car and truck transmission and engine casings, drive-train parts like connecting rods and differential housings, suspension castings, pressed parts, valves and pumps.
Both Equator 300 and 500 systems are accurate between 41ºF and 122ºF at any rate of temperature change and are capable of scanning speeds in excess of 8 inches/second. Every system is compatible with simple-to-use Organizer operator software, EZ-IO software for automation, and IPC (intelligent process control) software for updating tool offsets on CNC machine tools.
The Equator 500 is based on Renishaw’s Equator 300 gauging system but offers a larger working volume - 20” in diameter and up to 16” in height.
