ROUGHNESS MEASUREMENT

Product Highlights

CUTTING-EDGE TECHNOLOGY FOR MAXIMUM PRECISION

  • Fully automatic roughness measurement now possible from module 0.9
  • High-precision sensing and evaluation of superfine structures on surface-ground gearings

All precision measuring centers in the P-series can be equipped with a high-precision roughness measurement device. This roughness measurement can be integrated fully automatically into both the gearing measurement and the coordinate measurement, allowing all measurements to be conducted in one clamping.

  • Fully automatic roughness measurement of gearings from as small as module 0.9 mm, as well as shafts and plane surfaces
  • Evaluation of roughness parameters according to DIN EN ISO 4287 (Ra, Rz, Rt, Rmax)
  • Evaluation of contact ratio parameters according to DIN EN ISO 13565-2 (Rk, Rpk, Rvk, MR1, MR2)
  • Skid sensing system for effective separation of the usable signal from ambient influences
  • Integrated motorized swivel device for automatic alignment of the diamond needle with a diamond tip radius of 2 µm or 5 µm
  • Optimal scanning conditions with measuring runs similar to gear measurement
  • Comprehensive collision protection
  • Optimized design to protect the diamond needle
  • Extremely high resolution of 7 nm
  • Robust, reproducible measuring results even on extremely smooth (e.g., surface-ground) surfaces
  • Easy handling through integration into the normal measuring process
  • Precise measurement, even in the shop-floor environment
  • Fully automatic procedure for probe change (option)

Flexible Roll Testing on the R 300 – KLINGELNBERG Presents High-Precision Testing Technology

The Höfler Cylindrical Gear Roll Testing Machine R 300 is the latest machine development from the engineering company Klingelnberg in the area of cylindrical gear technology. Designed for all five roll testing methods, this compact machine is the ideal solution for anyone who wants to combine inspection cycles and reduce disassembly costs while benefiting from a user-friendly design.

Due to the increasing outsourcing of part and component production in large-scale transmission manufacturing, some transmission and vehicle manufacturers now require a certificate of quality for all gears installed in the powertrain. A further driver of ever-higher inspection levels is e-mobility. With the elimination of the combustion engine, there is an even greater focus on the noise behavior of the transmission than before, since the electric motor has a comparatively low masking effect on gear noise. To meet this challenge, Klingelnberg is building on roll testing technology, a familiar method from the bevel gear industry that is now moving into the world of cylindrical gears.

Only with a flexible test machine can the many quality control requirements for gears be met. Depending on the configuration, the R 300 provides the option of using all five roll testing methods. These include the single flank test, the structure-borne noise test and torsional acceleration test, the double-flank test, and the helix roll test. Thus the R 300 can be used at every point in the production process chain for cylindrical gears – from monitoring the soft cutting to checking the hardening distortions, to evaluating the noise behavior of the installation-ready gear.

Modular Machine Design
In terms of axis traversing paths, the Höfler Cylindrical Gear Roll Testing Machine R 300 covers the same component spectrum as the tried-and-tested Höfler Cylindrical Gear Generating Grinding Machine Speed Viper. Gear components up to an outside diameter of 300 mm can be tested, for example. In conjunction with the optional counter support, shafts up to
800 mm in length can be analyzed to determine their running performance and noise behavior. With a minimal footprint of 2 m2, the machine’s compact design also saves costs since it requires very little expensive floor space.

Convenient, User Friendly Design
The tried-and-tested design of the human-machine interface (HMI), familiar from the cylindrical gear and bevel gear processing machines, also ensures optimal user-friendliness in the R 300. The HMI is equipped with a 19-inch touchscreen, and important functions, such as “Clamp and release workpiece”, can be initiated via hardware switches. To make the user navigation as easy as possible, the operator is guided via a process-oriented menu structure to only those windows that are necessary for the specific test task at hand. This contributes significantly to the prevention of input errors and shortens the time required to train new employees.

Thus the R 300 offers the optimal solution for a compact, flexible, and highly precise testing technology for 100-percent quality control of cylindrical gears. The machine will be presented for the first time at the EMO Milano trade show in Hall 02, Booth D14 from 04 to 09 October 2021.

NOVELTY FOR MEASUREMENT FROM MODULE 0.9

Roughness Measurement

With the new miniature roughness probe, even gearings as small as module 0.9 can be measured fully automatically. This is possible thanks to a specially developed design that ensures contact with the largest possible portion of the gearing surface.

CUSTOM SOLUTIONS FOR BEVEL GEARS

Roughness Measurement

Alongside the straight standard design for pinions, an angled probe is available for bevel gear measurement.

VERSATILE APPLICATION

Roughness Measurement

All roughness parameters can be scanned quickly and easily on shafts as well as on the bearing surfaces of gearings.

PROVEN PROBE SYSTEMS FOR CYLINDRICAL GEARS

Roughness Measurement

Roughness measurement on Klingelnberg P machines is proven on several hundred machines over the last years. With the precise CNC-controlled measuring runs reproducibilities of 0.01 µm are achieved.

AUTOMATIC CHANGE, INCL. PLUG CONNECTOR

Roughness Measurement

In connection with the probe change magazine, not only is the roughness probe automatically changed, the plug connector for the sensor system is also inserted fully automatically.

CLEAR, DESCRIPTIVE PRESENTATION

Roughness Measurement

The roughness measurement curves and parameters for roughness and contact ratio are clearly displayed on the screen and in the measurement report – in the same way as evaluation of  the gear geometry.
