The highly-efficient innovative technology provides the stability and precision to the production process. The Mach Series cutting machine of Mitutoyo is equipped with the mentioned technology, which is suitable for the 24 hour – operating industry.
In-line CNC Coordinate Measuring System “MACH Series”
The MACH series is Mitutoyo’s in-line CNC coordinate measuring system that meets the requirement to operate around the clock in a factory is the structural design: with due consideration given to superior durability for stable operations, significant reduction in measuring time, accuracy assurance under a wide range of temperature environments, security, and ease of maintenance. The proof is the fact that this series has established trust and a track record, particularly in the automobile industry at home and abroad.
MACH-V substitutes a flexible measurement system for a series of gauge measurements on a powertrain manufacturing line. The high acceleration, high-speed probe movement results in high-throughput measurement.
High-speed drive up to a maximum of 866 mm/s
The vertical in-line coordinate measuring machine with excellent acceleration (8,770 mm/s-2), measuring speed (at the moment of contact: 20 mm/s) as well as drive speed. This system contributes to the reduction in total cost as an auto-measurement system, either in a line or at line side where a reduction in measurement time is required, and can also serve as a dedicated machine or a substitute system for gages.
Space-saving design helps installation in a production line
In consideration of installation between processing machines, the width of this machine has been reduced by 15% compared with its predecessor, thus contributing to a reduction in line length. Open access to the measuring area from the front/back and left/right has increased flexibility in the routing arrangements for a workpiece.
Accuracy assurance throughout a wide temperature range (5 to 35oC)
Real-time thermal compensation applied to measurements and origin setting ensures excellent accuracy (referred to 20oC) over a wide ambient temperature range. The graph below shows the effectiveness of the scheme in maintaining accuracy over a range of more than 30oC.
Improved dust resistance
This series has improved dust resistance by installing the drive system and scale units in a dust-tight enclosure at the upper part of the machine. The control unit and PC are installed in the dust-tight rack.
Improved ease of maintence
The ease-of-maintenance construction and air-free operation means less chance of maintenance problems occurring.
Higher speed and accuracy with barycentric drive
When the components of a CMM slide are driven by a force offset from the combined mass center, a rotation-inducing torque is produced that is detrimental to accuracy. To prevent this torque generation, the MACH-V Series employs the barycentric drive system, achieving an ideal drive that minimizes slide rotation, especially under high drive acceleration conditions, by applying the drive force directly through the mass center of the slide.
This technique enables high-speed measurement with minimum accuracy deterioration compared with commonly-used CMMs.
Workpiece thermal compensation essential for in-line measurement
Generally, during production, the temperature of a workpiece differs from that of the measuring machine due to processing and washing and is always changing.
To support in-line operations, the machine must continue accurate measurement (referred to 20 oC) even while the size of a workpiece is changing due to this temperature difference.
The following graph shows the high degree of compensation resulting when a MACH-V Series machine (at 20 oC) measured a certain workpiece while it cooled from 40oC towards 20oC
High-Speed In-line Coordinate Measuring Machine, Bursting out of the Inspection Room.
An absolute requirement for a measuring machine to operate around the clock in a factory is the structural design: with due consideration given to superior durability for stable operations, significant reduction in measuring time, accuracy assurance under a wide range of temperature environments, security, and ease of maintenance. The MACH Series is Miyutoyo’s in-line CNC coordinate measuring system that meets these demanding criteria.
The proof is the fact that this series has established trust and a track record, particularly in the automobile industry at home and abroad.
This is a horizontal CNC coordinate measuring system that achieves high throughput by increased drive speed, acceleration, and measuring speed. Space-saving and durability characteristics are compatible with line-side/in-line installation.
High-speed drive up to a maximum of 1,212 mm/s
The horizontal in-line coordinate measuring machine with excellent acceleration (11,882 mm/s-2) and measuring speed (at the moment of contact: 30 mm/s) as well as drive speed. This system contributes to the reduction in total cost as an auto auto-measurement system, either in a line side where a reduction in measurement time is required and can also serve as a dedicated machine or a substitute system for gages.
Space-saving design helps installation in a production line
This series comprises horizontal coordinate measuring machines intended for installation between processing machines. The horizontal-axis design allows this system to use the same workpiece handling and routing as the processing machines use.
Accuracy assurance throughout a wide temperature range (5 to 40 oC)
Real-time themal compensation applied to measurements and origin-setting assure excellent accuracy (referred to 20 oC) over a much wider range of temperature than conventional CMMs. The graph below shows the effectiveness of the scheme.
Improved dust resistance
This system incorporates a control unit and a PC for measurement and has attained superior durability through a design targeted on 24-hour operation.
Improved ease of maintenance
The ease-of-maintenance construction and air-free operation means less chance of maintenance problems occurring.
Extremely high throughput
The table below shows a comparison of transmission case measurements between a standard coordinate measuring machine (CRYSTA-Apex V Series) and in-line coordinate measuring machines (MACH-V9106 and MACH-3A653). The throughput of MACH-V and MACH-3A is extremely high.
MACH Ko-ga-me can be used in standalone applications or integrated into work cells. If required, the system can measure workpiece features that exceed the Ko-ga-me’s X-stroke by mounting the workpiece, or the Ko-game, on an auxiliary X-axis.
From status management to preventive maintenance.
Kickstart your smart factory through visualization.
Mitutoyo has developed new features that use a network to centrally manage manufacturing process information. The MeasurLink software package helps prevent defective parts by collecting and analyzing measurement data in real time. The Status Monitor (Smart Measuring System, or SMS), which indicates the operational status of the measuring machine; and the Condition Monitor, which indicates the physical condition of the machine itself, help maintain measurement accuracy, increase productivity, and improve maintenance management.
