PG66ZXYZXYYXZZYXMoving-Bridge Type CMMThis type is congured with the vertically moving ram (Z axis) mounted on a carriage, the carriage (X axis) horizontally moving on a bridge structure that is supported by the base and guided horizontally to form the Y axis. A workpiece is loaded on the base.Many Mitutoyo CMM models have adopted this type of structure, achieving high accuracy, high speed and high acceleration. Mitutoyo offers a strong lineup of CMMs of this type from compact models through to the largest sizes found in the inspection room.Fixed-Bridge Type CMMThis type is congured with the vertically moving ram (Z axis) mounted on a carriage, the carriage (X axis) moving horizontally on a bridge structure xed to the base and a table (Y axis) moving horizontally on the base. A workpiece is loaded on the moving table.Mitutoyo's Ultrahigh-accuracy CNC CMM LEGEX Series has adopted this structure type, providing the world's highest accuracy by minimizing error sources through exhaustiveinvestigation and analysis.Horizontal-Arm Type CMMThis type is congured with the horizontally moving ram (Z axis) mounted on a carriage, the carriage (Y axis) vertically moving on a column supported by the base and the column (X axis) moving horizontally on the base. A workpiece is loaded on the base.Mitutoyo In-line Type CNC CMM MACH-3A Series has adopted this structure type, attaining high-speed positioning, space-saving and durability to be compatible with line-side / in-line installation.Bridge / Floor Type CMMThis type is congured with the vertically moving ram (Z axis) mounted on a carriage, the carriage (X axis) moving horizontally on a double bridge structure (Y axis) that is supported on a hard oor. A workpiece is set down directly on the oor.Mitutoyo's Ultralarge Separate Guide CNC CMM has adopted this type that incorporates Mitutoyo's original structure (moving bridge on-oor installation type). It allows high-accuracy measurement of a large, heavy workpiece, featuring the world's largest measuring range.Mitutoyo coordinate measuring machines use four structure types that provide the benets of excellent stability, high accuracy, high measuring speed, convenience of workpiece clamping, etc.Coordinate Measuring Machines
