PITTLER SkiveLine

The GEAR CUTTING MACHINE that can do more than just gear cutting

  • Efficient production of internal and external gearings on ring gears, step-pinions, planetary gears or other cylindrical parts with diameter up to 400 mm 
  • Power Skiving or Hard Skiving machine for soft and hardened components
  • Sturdy tool head for high-precision machining results
  • Complete skiving tool service from one single source – from design of the tool to post-machining
  • Automatic generation of gear machining programs via intuitive user interface
  • Magazine for up to 20 tools and swarf-protected exchange of measuring sensors
  • Compact automation cell for fast workpiece changing in under 8 seconds
  • Cooling by emulsion, compressed air or a combination of both possible
  • Optional with integrated radial tooth-to-tooth testing device

Flexible. Efficient. Power Skiving.

PTTLER SkiveLine: Flexible. Efficient. Power Skiving.

Typical for Power Skiving, which PITTLER T&S has developed into a highly efficient gearing technology, is the diagonal arrangement of the tool axis to the component axis, known as the shaft angle. This adjustment of the tool, a defined axial feed and the coupled speed of tool and component result in a relative movement which effectively “peels” the tooth space from the component along the main cutting direction.

Since gear skiving can produce both internal and external gearing up to quality class IT5. On the tooth flanks, users meet highest surface requirements with an Rz value of less than 2 µm, while at the same time achieving a machining time reduced by a factor of between three and eight compared with competing methods, e.g. scudding, broaching, hobbing and gear shaping.

PITTLER skiving tools. Intelligent, individual, cost-saving.

The skiving 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). Roughing tools, which are used for gear units with a module larger than 3 and which carry out approximately 80% of the machining, are equipped with standard reversible blades. Use of such blades makes a decisive contribution to reducing skiving tool wear.

Powder-metal coated cylindrical or tapered tools are used for the finishing process. At the end of tool life, these canbe stripped, reground and then re-coated. PITTLER T&S offers a complete tool service from a single source – from design of the tool to post-machining.

More flexibility thanks to tool magazine

PITTLER SkiveLine: More flexibility thanks to tool magazine

The tool magazine of the SkiveLine series is the key to more flexibility during production of complex parts. With room for up to 20 tools it permits the efficient implementation of upstream and downstream processes such as turning, milling, drilling, deburring or measuring, right through to complete machining.

The tool magazine provides a special advantage for the gear cutting process since it relieves the strain on the tools during material removal. The rough skiving tool which is equipped with standard indexable inserts is loaded first and removes up to 80% of the machining volume. Then a high-quality, powder-metal-coated skiving tool is loaded. It is used for dressing only and is saved during rough skiving.

The PITTLER MultiTool increases the capacity of the toolmagazine. With up to 6 turning tools on one adapter, thereis more room for other tools. The PITTLER MultiTool reduces the tool change time to just 2 seconds.

PITTLER Automation Cell: Multi-functional loading system

PITTLER Automation Cell: Multi-functional automation.

PITTLER T&S has developed the automation cell PAC for the efficient material flow of workpieces up to 270 mm in diameter. Shorter travel paths and an integrated workpiece shuttle make significantly shorter workpiece changeover times for gear manufacturing possible. In addition, the loading paths inside and outside the machine cell have been separated to a major extent in order to minimise the carrying over of chips and emulsion.    

Despite the very compact design with a footprint of only 4.5 m², the loading system on the inside is easily accessible. Thanks to the open design, the PAC can be extended with additional testing or machining systems and thus be used in multi-functional applications. The automation cell is equipped with SPC discharge and NOK belt as standard. Two SkiveLine machines can be loaded by one PAC cell without any affect on cycle time.

Building on its vast range of relevant expertise, PITTLER T&S offers customised, application-specific automation solutions e.g. in the form of robot-supported manufacturing cells or pivoting grippers with connected conveyor belt integrated into the work chamber for larger components.

Highest manufacturing quality thanks to integrated workpiece testing

PITTLER SkiveLine: Highest manufacturing quality thanks to integrated workpiece testing

A radial tooth-to-tooth testing device can be integrated in the automation cell for the automatic quality testing of internal and external gearings. Gear teeth are thus inspected for manufacturing-related errors directly after machining and without leaving the machine. I.e. for a ring gear production this guarantees a consistently high component quality, since the measured values are transmitted in real time to the machine for readjustment, resulting in correspondingly fewer faulty parts.

Precision clamping devices from a single source

PITTLER SkiveLine: Precision clamping devices from a single source

The key to precision can often be found in a machine’s chucking concept. PITTLER T&S works together with SWS Spannwerkzeuge GmbH from Schlüchtern and Albert Klopfer GmbH from Renningen on the development of chucking tools. As associated partner companies, SWS and Klopfer work for the entire DVS TECHNOLOGY GROUP and develop complete solutions as well as standard customized chucking devices “Made in Germany”.  Both companies develop tailor-made clamping systems which are matched exactly to your workpieces.
