R&P Metrology's RPG 1600DS four-axis generative inspection machine, available from Kapp Technologies, accommodates gears as large as 1,600 mm (62.99") in diameter with a tailstock that swings to a safe position when measuring large-diameter gears. The tall, stiff tailstock is also capable of holding shaft parts as long as 2,000 mm (78.74"), and can measure face widths ranging to 1,200 mm (47.24").
The inspection machine’s X axis runs on precise mechanical bearings for rigidity, while the Y and Z axes use granite guideways and air bearings. All linear axes feature linear motors for precision. The air-bearing rotary table is mounted on a granite bed and is driven directly by a torque motor. Because the machine rests on an active suspension system, no separate foundation is required.
Both gear inspection and prismatic (3D CMM) measurements are possible with CNC and analysis software. The RPG 1600DS is compliant with I++ protocol, accommodating a variety of CMM inspection packages.
