New High-Speed, High Acceleration Coordinate Measuring Machine Doubles the Effective Measuring Range at a Given Tolerance
The new CRYSTA-Apex®S Coordinate Measuring Machine from Mitutoyo America Corporation brings new levels of performance and economy to the 1.7 µm class of CNC CMMs.
With a maximum error of MPEE = (1.7+3L/1000) µm, the new Mitutoyo CRYSTA-Apex®S more than doubles the effective measuring range at a given measurement tolerance as compared to typical CMMs in its class. Additionally, the CRYSTA-Apex®S drive features high-speed (max 519 mm/s) and high acceleration (max 2,309 mm/s2). These advances result in higher throughput for greater productivity and lower total owning and operating costs.
The CRYSTA-Apex®S uses the new UC-400® controller to manage digital servo system control loops for position, speed, and current. This makes it easy to implement various types of control algorithms. Additionally, the digital servo system has a wide dynamic range and is highly resistant to drift over time.
Extreme rigidity helps the CRYSTA-Apex®S maintain accuracy. The Y-axis guide rail is integrated into one side of the granite surface plate. Precision air bearings located on the bottom, front, rear and upper surfaces of the X-axis slider minimize vibration and ensure stability even during high-speed, high-acceleration operation.
Accuracy is further enhanced by an advanced Temperature Compensation System. The System consists of a thermometer unit that measures the temperatures from thermal sensors located on the scale units of the CMM main unit and from a set of workpiece thermal sensors. The temperature data is transferred to the UC-400® machine controller for thermal compensation. For proper workpiece compensation, the thermal expansion coefficient of the workpiece material is entered by the user; since the material of scale units of the CMM is constant, this expansion coefficient is permanently stored in the temperature unit.
The CRYSTA-Apex®S supports a wide range of probes that offer increased capabilities including the MPP-310Q scanning probe that collects cloud point data at speeds of up to 120 mm/s. Other probes suited for screw depth measurement, ultra-small diameter measurement and non-contact measurement are also supported.
