gear profile grinding machines VX 55 / 59

machining of gears and special profiles

machine concept
All machine types of the gear profile grinding machines VX series are based on a modular system which is designed for the use of various tool technologies. All versions are exclusively configured for profile grinding.

The gear profile grinding machines of the VX series are extremely suitable for meeting the highest requirements concerning the final quality of the produced gears. Based on exchangeable grinding units, machines of this series can work both external and internal gears as well as spur and helical gears and other profiles.

The following tool concepts are offered:

  • dressable ceramic tools for prototype machining
  • non-dressable CBN tools for the high-productive batch production

Since the grinding adapter can hold two exchangeable grinding spindles, the cut segmentation is possible due to the sequential use of roughing and finishing tools in one single workpiece set-up. Alternatively, two or more gears can be machined in one set-up.

The CNC dresser is integrated in the working area of the gear profile grinding machines of the VX series and allows any grinding wheel profiles to be generated.

The combination of measuring system and profile dressing unit allows the automatic machining according to the so-called GMG strategy (grinding – measuring – grinding). The dressing and grinding programme is automatically generated based on the entered gear data.

control and software
The control system Sinumerik 840D sl is equipped with an operator-friendly menu-driven user interface, developed by KAPP NILES to match the specific machining requirements. By entering the required workpiece and technology data profile modifications and lead modifications, technological corrections as well as axes-corrections can be done via editor.

measuring system
The optional measuring device allows to measure and to evaluate gear qualities against specifications. This functionality is mainly used to optimise the set-up processes in the machine, particularly in order to eliminate non-operational periods due to external measuring processes as far as possible. Alternatively, random samples can be tested during processing.
