Klingelnberg P 65

The Klingelnberg P 65 is a gear measuring machine with 5 CNC measuring axes for workpieces up to 650 mm (25.6 in) in diameter. It does not cut or grind. It checks gears across a module range of 0.30 – 35 mm, with 0.20 mm shown in brackets and tied to a footnote in Klingelnberg's table.

Vertical capacity comes in two versions. The vertical measuring interval is 800 mm, or 1,200 mm in brackets, and the distance between centers is 50 – 1,000 mm, or 1,500 mm in brackets. Read across the rows, the bracketed figures describe a taller column: machine height goes from 2,430 mm to 2,930 mm while the footprint stays at 2,220 x 2,140 mm. The decision is therefore about ceiling clearance and shaft length, not floor area. For rotating parts the permissible moment of inertia is 100 kgm², which matters most for large-diameter gears, since inertia rises with the square of the radius.

Accuracy is stated as a length measuring error MPE_E0 of 1.8 µm + L/250 mm, tied to a reference temperature gradient of 2 K/h, 12 K/d and 2 K/m. Take the two rows together: the error figure assumes the room changes by no more than 2 K in an hour and 12 K over a day, and varies by no more than 2 K per metre. A shop that cannot hold those gradients around the machine should plan an enclosure or a measuring room.

Services are light. The compressed air connection is 6 bar at 1 l/min, a small demand for a shop air line.
