Cut Knurling

 

Which profiles can be produced when cut knurling?

It is only possible to produce the profiles RAA and RGE (30°/45°) according to DIN82.

 

Form Knurling

 

Which knurling profiles can be produced with form knurling?

With form knurling all profiles according to DIN82 can be produced.

 

Knurling Wheels

 

When are carbide knurling wheels used for production? What is the advantage?

Batch production of work pieces made of brass, aluminium or free-cutting steel.  Advantage: Ground profiles can improve tool life for processing aluminium.

The Knurling Technique

 

Which knurling technics are there? Where are the differences?

The knurling technique can be divided into the two disciplines: form knurling and cut knurling.

The knurling profile when form knurling is achieved through a cold deformation of the material. When cut knurling, the profile is milled through machining. You will find more information to each technique under the headings Form Knurling / Cut Knurling as well as in the "Application Support" section.

General tool characteristics

 

What is the difference between left- and right hand tools?

A right / left - hand model is designed for the respective machine types – See also Machine Characteristics. For more information go to Support/Application Support.

Technical Support Facilities & Order Information

 

Which information is required for a knurling tool offer / knurling tool order?

Required shank size in mm - Model(right-hand / left-hand) - Centre height to be integrated (Jes / No) - Suitable for sliding head auto lathes (Yes / No)

zeus® Cut Knurling Tools (RF1, RF2, RF3)

 

What are the advantages of the RF3 series? Are there any application restrictions?

With the RF3 serie an excellent visual profile and superb surface finish can be produced. Further, the processing of thin-walled material is possible. When knurling with this tool type, only a minimal lateral pressure is produced. It is only possible to produce the profile RGE (30°/45°) according to DIN82 with this tool type. The RF3 series is only suitable for cylindrical work pieces. Knurling to a shoulder is not possible.

zeus® Form Knurling Tools (RD1, RD2, RD3)

 

What are the advantages of the RD3 series?
Are there any application restrictions?

The main advantage of the RD3 series lies in the minimal lateral pressure, and hence reduced strain on machine and work piece, exerted. The tool is especially suited for thin-walled work pieces and small work piece diameters.

With the RD3 series, knurling is only possible in axial tool direction (The knurling tool can not be placed at any position/in the middle of the work piece) – It is only possible to produce the profiles RAA, RGE (30° / 45°) according to DIN 82.
