Gear Hobbing Machine Gleason-Pfauter P400

For the manufacturing of test gears as well as for technological investigations in the field of hobbing, the gear group of the WZL is equipped with the gear hobbing machine P400 from Gleason / Pfauter. For technological investigations, the analogy trial of fly-cutting is used in particular. The machine features a rigid and thermally stable machine structure as well as directly driven machine axes. The P400 is optimized for workpieces up to a module of 8 mm and a diameter of 400 mm and can be extended up to 500 mm. The maximum achievable tool spindle speed is 900 min-1].[



Gear Measurement Center Klingelnberg P16

The gear measuring center Klingelnberg P16 is a CNC-controlled measuring machine for components up to an outside diameter of 160 mm. In addition to the measurement of spur gears, it is also possible to carry out measurements on bevel gears, worms and worm gears. Measured values are dimensional, shape and position deviations of the components. For this purpose, a 4-axis path control system is used in conjunction with a 3D measuring system. In addition to the measurement of components, the possibility of tool measurement is also available. Here shaper and shaving tools as well as hobs can be measured for their dimensional accuracy. Various software modules offer the possibility of specifying and automating measurement processes that are specifically designed to the measurement task.



Cold Rolling Machine Profiroll PR15HP

The cold rolling machine is characterized by roll forces of up to F = 15 kN at spindle speed of up to n0 = 120 min-1. The cold rolling process can be used to densify powder metal spur and helical gears of a modul of up to mn < 3,5 mm. The PR 15 HP enables fast and reliable cold rolling of PM gears. Furthermore, splines with an module of up to mn < 2mm can be formed into solid and hollow shafts.



Gear Grinding Machine Klingelnberg Viper 500 KW

For the production of test gears as well as for technological investigations on grinding, the WZL department of gear technology has a gear grinding machine of the type Viper 500 KW (combination of machine types K and W) from Klingelnberg Höfler at its disposal. On the grinding machine, both the process of discontinuous profile grinding as well as continuous generating grinding can be applied. Furthermore, the machine is suitable for grinding external and internal gears as well as beveloid gears with an external diameter of up to ds = 500 mm. In addition to the conventional machining of cylindrical gears, the grinding machine also enables the machining of rotationally symmetrical free profiles according to a point cloud. Compared to a conventional Viper 500 W, the smaller tool spindle of a Viper 500 K allows grinding wheels with outside diameters in a wide range of sizes ds ≈ 50-300 mm to be used on the machine tool. The maximum spindle speed of the grinding machine is ns = 17,000 min-1, the maximum feed rate is vf = 20,000 mm/min.



Gear Honing Machine Gleason 150SPH

For technological investigations in the field of gear honing the, the WZL department of gear technology has a gear honing machine of the type 150SPH Spheric®-Honing from Gleason-HURTH. The gear honing machine is suitable for hard finishing of external gears with an external diameter of da = 5 mm to da = 150 mm and a module of mn = 0,5 mm to mn = 4 mm. The maximum face width of the gear to be machined is bmax = 50 mm. The honing machine has two via an electronic gear drive synchronized spindles. These are operated in two different work spaces inside the machine. One work space is for the honing process and the other is the operating space, where the workpieces are replaced. The maximum speed of the workpiece spindle is n2 = 10,000 min-1 and the maximum speed of the tool spindle is n0 = 3,000 min-1.



Turning Machine VDF DUS 560

The turning machine VDF DUS 560 is a Boehringer machine tool in horizontal orientation. The machine is mainly used for analogy trials. Thereby constant chip geometries are reproduced and characteristics of materials and tools like influence of cutting edge radius, coatings, etc are investigated. Furthermore cutting force coefficients for the used force models in gear hobbing are determined. The advantage of this type of trials is the fast workpiece and tool purchase and the easy trial design.
