New Gear Skiving Machine LK 300/500
The principle of gear skiving was invented back over a century ago. Yet in practice the highly dynamic kinematics involved in this method frequently caused major problems: to date this method offered more disadvantages than benefits, as tool wear and tear had a negative impact on machining quality. Liebherr-Verzahntechnik GmbH has now mastered both the mechanics and the technology involved, meaning it is now in a position to create the ideal process for conical and cylindrical tools.
Machine, tool and process from a single source.
- Deburring & tool changer
- Technology design
Economical production solution for chamfer/deburring
It is easier said than done – if it takes too much time for two processes to run consecutively on a single machine or single clamping operation, then the design must simply allow both processes to take place simultaneously. As easy as the principle sounds, technical implementation is very complex. We have integrated an entire second processing unit for ChamferCut tools – two machines in one, so to speak. This newly developed solution has eliminated the main disadvantage of previous ChamferCut applications, namely that they prolong machining time.
- High chamfer quality and precise chamfer geometry
- No bulging or material deformation
- Very long service life (including with dry machining)
- No needle swarf
- ChamferCut is easy to sharpen
- Easy tooth-root chamfering
- Small diameters possible
- Lowest tool costs
Smart Factory: Industry 4.0
Industry 4.0 is a trend that has been prevalent for some time. This transformation via the “smart product” to the “smart factory” is a continuous process. Our customers have very different priorities and requirements, which we need to meet to their complete satisfaction. This is a challenge that we are keen to take on.
Nowadays operators should be able to perform highly complex procedures as simply as possible. To make this happen, they need the appropriate technical support. This support is to be found in modern user interfaces, which also reduce the incidence of problems due to input errors. Thus, for example, our new HMI, LHGe@rtec, enables hob data to be loaded directly from the manufacturer into the machine. The tools and tool data are then displayed and can immediately be visually checked for completeness and accuracy. The new HMI’s multi-touch function caters for modern forms of machine operation. This graphic input support is also available for operator-created part programs.
