Mitutoyo launches the first lineup of its unique probe systems developed with Mitutoyo's own technologies.

In order to provide its users with a full line of CMM probe systems as a total solution to answer their measuring needs, Mitutoyo Corporation has been vigorously pursuing the development of new, unique probe systems with a variety of characteristics. This pursuit has been finally fulfilled; the new line of probe systems, successfully developed and merchandised, will be shipped to all the global markets starting in mid-November of this year.

[Development of the "CMM probe system"]

In the past, Mitutoyo's coordinate measuring machines used the probe systems manufactured by Renishaw, England, with the few exceptions to this being Mitutoyo's use of its own scanning and vision measurement probes. In order to improve the performance of its CMMs, however, Mitutoyo decided to develop its own probe systems. Hence, it has been engaged in developing various technologies and products for that purpose, as shown below: < Mitutoyo's policies for developing its own probe systems for Mitutoyo CMMs > (1) Development of a probe system that allows measurements with "higher-accuracy" (2) Development of probe systems incomparable to those by other manufacturers. (3) Development of a probe system that allows "non-contact" measurements. The following five probe systems will be merchandised and delivered in the first launch of a series of Mitutoyo probe systems 1) For high-accuracy measurements • Ultra-high accuracy touch-trigger probe system: MTP2000 2) For high-speed scanning measurements • Hi-speed scanning probe system: MPP-100 3) For high-accuracy scanning measurements • High-accuracy scanning probe system: MPP-300 4) For applications that are unavailable with probe systems by other manufacturers • Probe system for measuring effective screw depth: MPP-10 5) Enhanced application of vision measurement technology • Vision measurement probe system for CMM: QUICK VISION PROBE (QVP) 6) Development of software to maximize the performance of various probes • Incorporated into probe systems and measuring software Our plan for the future is to develop two groups of CMM probe systems: one that can coexist with and the other that excludes Renishaw probes. A total of 700 sets (all five models combined) per year are expected to be sold (domestic and overseas sales combined).

[FEATURES & SPECIFICATIONS]

MTP2000

1.

A touch trigger probe that allows measurements with ultra-high accuracy. Ideal for measuring precision parts, including metal moulds, etc., which require high-accuracy measurements. 1) Employing Mitutoyo's unique high-accuracy coordinates recovery system (patent pending) and sensing algorithm (patent pending) to achieve high repeatability and non-directional high sphericity. 2) When used in combination with Mitutoyo's ultra-high accuracy CNC CMMs, the "LEGEX Series" or the "RV-II Series", the MTP2000 can achieve measurements with even higher accuracy.

2.

Equipped with the automatic probe changing system • The MTP2000's auto-joint system allows it to be interchangeable with other probes. The MTP2000 is interchangeable with a touch probe as well as a non-contact type probe, thus allowing a larger variety of measurements.

Repeatabilityσ 0.075μm Roundness 0.4μm Sphericity 0.5μm Measuring directions ±X , ±Y , +Z Over- travel Horizontal ±5o Vertical 2mm Measuring force Horizontal 0.96N Vertical 2.94N Probe diameter 35mm Probe mount Auto-joint

MPP-100

1.	A scanning probe that allows high-speed measurements. The MPP-100 allows high-speed evaluations of contour errors that occur in measurements of complex free curves. 1) Employing the high-accuracy guide system and the high-speed scanning control technology to achieve high-speed scanning measurements with high-accuracy scanning. 2) Increased scanning speed with a maximum of 120mm/s for dramatically improved measuring efficiency.
2.	Supports a long stylus • A long stylus up to a maximum length of 200mm can be installed in the MPP-100. This means that not only long workpieces can be measured with this probe, but also a variety of workpieces can be measured with just a single probe.
3.	Stylus changing system • The stylus changing system of the MPP-100 allows the stylus to be automatically interchanged with one that best suits the contour of the workpiece, thus allowing a wide range of applications.

MPP-300

1.	The MPP-300 is a scanning probe for measurements with ultra-high accuracy. It allows high-accuracy evaluations of contour errors that occur in measurements of complex free-forms. 1) Equipped with Mitutoyo's own unique high-accuracy guide system and the scale units employing ultra-high accuracy glass scales with a linear thermal expansion coefficient of near-zero, the MPP-300 provides scanning with an extremely high accuracy. 2) The MPP-300, when installed in Mitutoyo's ultra-high accuracy CNC CMM "LEGEX Series" or "RV-II", can provide the highest level of scanning accuracy in the world.
2.	The MPP-300 supports a long stylus • A long stylus up to a maximum of 200mm can be installed in the MPP-300. This means that not only long workpieces can be measured with this probe, but also a variety of workpieces can be measured with just a single probe.
3.	Stylus changing system • The stylus changing system of the MPP-300 allows the stylus to be automatically interchanged with one that best suits the contour of the workpiece, thus allowing a wide range of applications.

MPP-10

1)	The MPP-10 is a probe for use with a coordinate measuring machine, and is designed to measure the effective depth of a screw.
2)	The MPP-10 allows CMM to measure the effective depth of a screw instead of using an existing dedicated measuring machine with a screw gage.
3)	Single CMM equipped with an MPP-10 can perform both general coordinate measurements and measurements of the effective depths of screws.
4)	The patent-pending sensing system that employs an elastic hinge and a rain gage allows high-speed measurements of effective screw depths in constant volumes.
5)	The automatic probe changing system of the MPP-10 allows interchangeable use of other touch signal probes.

*	This product was developed in cooperation with the Graduate School at Hiroshima University, under the direction of Professor Makoto Kaneko, who specializes in artificial complex systems engineering.

QVP

1.

By installing the QVP vision measuring system in a CMM, miniscule workpieces can be measured that cannot be measured with a CMM alone.

< CMM with the QVP vision measuring system allows the following: > 1) Measuring workpieces that are too small for a touch probe to enter. Small holes with a diameter of 1 or less, or workpieces with a width of 1 or less, for example. 2) Measuring a workpiece with a soft surface, contact with which will cause a disfiguration. 3) Measuring a flat workpiece that cannot be measured by probe contact. 4) Measuring a workpiece that is too heavy or too large to be placed on the stage of a vision measuring system, but for which a vision measurement is preferred. 5) Use by the user who measures his workpieces with a CMM and a microscope.

1.	The QVP system allows high-speed, high-accuracy non-contact vision measurements by a CMM.
