Klingelnberg P 40 Precision Measuring Center

The Klingelnberg P 40 Precision Measuring Center checks cylindrical gears up to 400 mm in clamping and testing diameter between centers, in modules of 0.30 – 20 mm, with a workpiece weight of up to 300 kg. Module 0.10 mm appears in brackets in Klingelnberg's table, so treat it as outside the plain range until confirmed.

Its accuracy statement has three layers, each tied to a standard. For gear measurement the machine is classed Group A under VDI/VDE 2612 sheet 6. For length measurement the error MPE_E0 follows ISO 10360-2:2010. For the rotary axis, roundness and total axial runout follow VDI/VDE 2617 sheet 8.

The numbers depend on the room. Between 18 and 22 Celsius, MPE_E0 is 1.8 µm + L/450 mm, roundness 0.3 µm and total axial runout 1.5 µm. Between 15 and 35 Celsius the constant part of MPE_E0 stays at 1.8 µm but the length term becomes L/250 mm, roundness rises to 0.5 µm and axial runout to 1.8 µm. The difference in length error between the two bands is all in the length term, so the penalty for a warm shop grows with the length being measured. A long shaft measured over most of the Z interval pays more than a narrow gear.

That Z interval is 550 mm, with 700 mm in brackets, and the distance between centers is 50 – 800 mm, with 1,000 mm in brackets. The X axis measures over ±115 mm. Installation is undemanding for the accuracy class: 0.7 kVA including the printer, compressed air at 6 bar and 1 l/min, and a net weight of approx. 2,200 kg with standard equipment.
