STRATO-Apex Series: A state-of-the-art CNC coordinate measuring machine that achieves high accuracy combined with high-speed operation

Improved machine rigidity

High speed and accuracy in measurement is ensured by a redesign of the machine body that has improved rigidity of the structure, and by a remodeled guide mechanism

Newly developed, built-in, high-performance controller

Uses a digital servo system that processes all control loops for position, speed, and current as digital signals.
The digital servo system offers the following benefits:
(1) Little drift or deterioration with time
(2) Wide dynamic range
(3) Easy implementation of various types of control algorithm

Scanning measurement technology

High-performance scanning measurement has been achieved through the improved structural rigidity and incorporation of a newly developed compensation technology
Maximum permissible scanning probing error: MPETHP = 1.3 μm (STRATO-Apex 574)
Maximum permissible scanning test time MPTtHP = 40 sec (STRATO-Apex 574)
(cf. Existing FALCIO Series: MPETHP = 2.2 μm)
                                             MPTtHP = 110 sec.)
*Probe used: SP25M

Internal heat generation minimized

The controller is positioned outside the main unit, thereby eliminating the effect of the generated heat on the main unit. Compact layout has been achieved, resulting in a small footprint, even with the externally positioned controller.

Ultra-high precision glass scales

• An ultra-high precision crystallized glass scale which has practically no thermal expansion (coefficient of linear expansion 0.01 × 10-6/ °C) is combined with a high-performance reflective linear encoder with resolution of 2/100 μm to create the ultra-high accuracy measurement unit installed on each axis of STRATO-Apex. This is basically the same unit as used in the LEGEX Series of ultra-high accuracy CNC coordinate measuring machines. (Applies to STRATO-Apex 700/900 Series).
• A unique securing method used for the scales minimizes the hysteresis error that can result from the difference in the coefficients of linear expansion between the installation plane and scale.

Vibration-damping unit included as a standard accessory

Vibration of the floor where the unit is installed shows up as measurement value variations. The STRATO-Apex Series comes equipped with a vibration- damping unit that uses auto-leveling air springs. The vibration-damping unit not only prevents floor vibrations from reaching the main unit, but also has a function that uses a sensor to detect load changes caused by movements of the individual axes and placement of a workpiece and quickly restores the main unit to horizontal orientation.
