Pittler PV 600 gear cutting machine 

Power skiving is a machining method used for the manu facture of gear teeth, based on the patent by Wílhelm von PITTLER. Over the past few years, the latest developments ín
manufacturing engìneering have led to the technology becoming an effícient and flexible alternatíve for gear components.
Týpical for Power skiving ís the diagonal arrangement of the tool axis to the work piece axis, known as the shaft angle. This adjustment of the tool, a defined axial feed and the coupled speed of tool and work piece result in a relative movement which effectively "peels" the tooth space from the component along the main cutting direction.

High-precision measuring sensor for in-process measurement in the machine enclosure
■ Time-saving corrections
■ Two-ball dimension & flank line for gear components
■ Protected from swarf as the sensor can be exchanged in the tool magazine

Power Skiving process in conjunction with complete machining. An integrated tool magazine allows this efficient gearing technology to be presented without compromise in a 5-axis machine alongside the processes turning, milling, drilling, grinding, thread cutting and
measuring. The fléxible use of technology allows machining wíth a maximum of 2 chucking procesśes, thus guaranteeing high precision of tolerances.
The advantages of Power skívíng:
High tooth gear tooth quality
■ Low surface roughness
■ 50% reduction in cycle time compared with gear shaping
The advantages of complete machíníng:
Reduction of time-consuming retooling, transport and storage times
■ Less floor space requirement
■ Less capital lockup (one machine for several processes)

Intellígent tool concept
The tools and associated blade geometries are another important factor in Power Skiving. They are designed individually for each gear unit (module and number of teeth). Specially manufactured bodies with reversible, inserted, cutting blades are used for the róughing
tools which carry out approximately 80% of the machining. Powder metal coated tools are used for finishing. At the end of tool life, these can be stripped, reground and then re-coated.
