Camshaft milling machines RFN 10

HELLER external milling of camshafts:

• Cutting speed is generated by the tool.
• Feed rate is generated by the workpiece rotation.
• External cutters are used for the outer diameter.
• Cutter diameter can be used for most hollow cam profiles.
• The tool profile is designed according to the profile to be milled.

• Two interpolating NC axes are used for the machining of cam profiles.
• Rotary feed is generated by the workpiece rotary axis and the milling unit(s) follow as required by means of one/two linear axis/axes.
• The plunge cut to the cam profile is carried out by the linear axis of the milling unit with stationary rotary axis or with a spiral movement using interpolation.
• In order to withstand cutting forces, workpieces are clamped and supported by two hydraulic clamping chucks with electrically synchronized rotation and by one or two additional steady rests which can be positioned via NC programming. This steady rest is set on a separate guideway below the milling slides for unrestricted positioning within the travel paths.

• Machining with one or two milling units possible.
• Machining of cam profiles and chamfers in one operation is feasible.
• Use of gang milling cutters possible.
• Radial alignment through bore or groove
• Accurate machining of journals makes rough (“green”) grinding obsolete.
