SERIES
Carbide Threadmills Solid Carbide Threadmills provide a highly controlled and repeatable method for producing internal and external threads in CNC machining environments. By utilisng circular interpolation, thread milling eliminates many of the limitations associated with traditional tapping while improving process stability, accuracy, and tool life in most materials.

Features & Benefits
Thread milling from solid saves valuable production time by reducing the number of tools required to generate a quality thread. No longer do you need to drill before threading, complete the whole process with the one tool.
Deep thread quality is improved through left-hand cutting geometry and through-tool coolant. Together with reduced cutting length engagement, these features minimise vibration, enhance process stability, and extend tool life by efficiently evacuating chips from the cutting zone.
Helical flute threadmills optimise chip formation and evacuation, delivering more stable cutting conditions, improved thread quality, and extended tool life with through-tool coolant chip evacuation.

Practical application of thread milling cutters

(milling cutter) center point path vm
d

entry cycle 180° (always half feed rate)
1 Tool clamping: good concentricity is important, therefore clamping
as short and rigid as possible· 2 Enter tool data in machine memory 1) Tool length from the front face, take drill/thread milling cutters (DTMC) rom point. 2) Measure tool radius with tool pre-setting equipment. General rule:measured radius - 0.022 x pitch provides the input value in machine memory. 3 Input of CNC program in control: (preferably Integrated as sub-program at corresponding positions) a) Call-up of a self-controlling cycle (procedures should be known) b) Integration of data file from our threadmill-software (DIN or Haidenhain). 4 Trial run over workpiece a) Tool length dimension in memory extending by an approximate value dependent on contact length (i.e. 30 mm) or offset zero point. b) Run program in single set, visual check of travel path. c) Allow program to run in automatic mode. Attention·: With controls where It Is not definitely clear what milling path is assigned it must be clarified if the feed Is positioned on the external path vf or at the centre path vm. As a rule we specify the milling centre point path vm. 5 Application in workpiece: Re-set the tool extension or the zero point. Then allow the program to run In the workpiece the feed regulation must be 100% selected. Should the thread not be true to gauge, the tool radius requires correction in the tool memory: Example: • thread too tight: Radius correction - Input • thread too large: Radius correction + Input
