If you're in the cutting tool industry and want to enhance your thread production process, Multidec®-WHIRLING is the solution for you. Unlike traditional thread turning, which requires multiple cutting passes, Multidec®-WHIRLING gets the job done in a single pass, leaving you with smooth, burr-free threads and top-notch surface quality. With up to 12 cutting edges at your disposal, you can cut machining time significantly (up to 50% faster) and save on costs. Plus, you can count on precision, as concentricity errors are minimal (less than ±0.005 mm), ensuring high-quality threads. Changing the whirling tool is a breeze, thanks to quick and easy rotations, which reduce setup time.
For optimal results, UTILIS offers machine-specific variants with various flight circles and lengths. Utilizing UTILIS standard blanks means you'll have shorter delivery times, with coatings tailored to your material. You'll find whirling heads with different flight circles, suitable for multi-start threads, and virtually no limits on thread lengths.
The cutting edges of Multidec®-WHIRLING are inspired by Multidec®-CUT, making them ideal for sliding headstock automatic lathes with a bar capacity of up to Ø 10 mm. The inserts, each with two cutting edges, are securely screwed onto the holders with remarkable repeatability (less than 0.01 mm).
Cutting for all needs - Examples of machining
Standard thread form (single start)
Standard thread HA 4.5 in 1.4441/316LVM/SUS 316
Mission: Substantial saving on machining time and improved service life with no loss of quality
Outcome:
- Machining time halved
- Service life improved to 175%
- High surface quality
- Smooth running
- Identical quality
Special form (one, two and three starts) with blank
Deep double thread in titanium grade 5
Mission: Production of double threads with a high material removal volume. The client requires high accuracy despite the heavy cutting forces.
Outcome:
- High surface quality
- Extremely smooth running
- High accuracy
Special form (one, two and three starts) with blank
Worm thread in 11SMnPb30
Mission: Replacement of the traditional cumbersome manufacture of two-start worm threads with a view to improving the surface quality, enhancing process security and minimising the chip problem.
Outcome:
- The shape is perfectly accurate
- Very good surfaces
- More than twice as fast as using the traditional process
- High process certainty
Special form (one, two and three starts) with blank
Eccentric whirling in 1.4057 / 430F / SUS 430 F
Mission: Eccentric production on the long lathe replaces expensive traditional techniques. Whirling permits fast component production with a high degree of accuracy and without rechucking.
Outcome:
- High surface quality Ra 0.15-0.18
- Feasibility without expensive clamping fixtures
- High cutting speed
- Utmost precision Ø10.5mm ±4 µm or Ø7mm ±3 µm
- Faster than specified process time
Special form (one, two and three starts) with blank
Lathe/milling centre with HSK/PSC or similar connection
Mission: Use of thread whirling on lathe milling centres to produce thread lengths of up to 5 x Ø and reduce machining time
Outcome
- Very good surface
- Stable clamping
- Extremely smooth running
- 400% higher productivity than on a long lathe
