Pittler PV 1600 gear cutting machine

Power Skíving is a machining method used for the manufacture of gear teeth, based on the patent by wilhelm von
PITTLER. Over the past few years, the latest developments ín manufacturíng engineeríng have led to the technology becoming an efficient and flexible alternative for gear components.
Typical for Power skivïng is 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

PITTLER T&S is the only manufacturer on the market to offer the
Power Śkiving process in conjunction wìth 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 ćutting and
measuring. The flexible use of technology allows machining with a maximum of 2 chucking processes, thus guaranteeing high precision of toléranceś.
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 machiníng:
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 roughing tools which carry out approximately 80% of the machining. Powdermetal coated tools are used for finishing. At the end of tool life, these can be stripped, reground and then re-coated.

The tools can be changed automatically in the machine as a result of the integrated tool magazine.
