Dişli Dönme Uçları
Custom-profile carbide inserts and cutter-body solutions for worm shafts, bone screws, lead screws, rotors and other long or complex external threads.
More than a profile insert
A stable whirling process depends on the complete tooling system. ONMY reviews the insert profile, cutter-body pocket, helix setting, workpiece material and required thread quality as one application.
- Full-profile geometry developed from pitch, lead, starts, diameters, flank angles and radii
- Insert platform and locating surfaces matched to the existing cutter body or a new tooling design
- Carbide substrate, PVD coating and cutting-edge preparation selected for the material and wear mode
- Replacement inserts can be evaluated from drawings, samples and pocket information
Geometri ekleme
Custom full-profile grinding with application-specific rake and clearance.
Cutter body
Pocket, cutting diameter, insert count and machine interface are reviewed.
Process support
Drawing and current machining problems guide the tooling recommendation.
Choose by the part you manufacture
The general whirling page introduces the tooling system. Each application page then focuses on the thread geometry, workpiece material and information needed for that part family.
Sonsuz Mil Dönen Uçlar
Custom inserts for worm shafts, worm screws, steering worms and single-start or multi-start transmission profiles.
Kemik Vidası Dönme Uçları
HA, HB and custom-profile inserts for titanium alloy and stainless steel bone screws, with matching D12 cutter-body options.
Lead Screw and Rotor Inserts
Drawing-based whirling inserts for long lead screws, feed screws, rotors, micro screws and non-standard profiles.
Insert, cutter body and machine interface
The same thread profile can behave differently when the cutter diameter, insert count, helix setting or pocket position changes. These details are confirmed before the insert profile is finalized.
Whirling insert
Profile geometry, edge preparation, carbide grade, coating and usable cutting edges.
Cutter body or ring
Cutting diameter, pocket count, insert seat, runout requirement and coolant access.
Whirling unit interface
Machine model, attachment model, connection dimensions and available helix-angle adjustment.
Workpiece and quality target
Material, thread tolerance, surface finish, burr control, tool-life target and production volume.
Why thread whirling is used
The cutter body rotates at high speed while the workpiece rotates at a lower speed and feeds axially. Multiple inserts share the cut and form the thread profile close to the supported area of the workpiece.
Set the helix relationship
The whirling unit is aligned with the thread lead, workpiece diameter and machine setup.
Rotate the cutter body
Multiple inserts pass the workpiece and divide the cutting load around the ring.
Synchronize workpiece and feed
Workpiece rotation and axial feed create the required pitch, lead and number of starts.
Form the finished profile
The insert geometry produces the specified flanks, root, crest and transition radii.
Designed from complete application data
Pitch alone does not define a whirling insert. The finished profile, cutter-body geometry and machine setup must be reviewed together.
Thread and machine data
Provide the information currently available. Missing details can be confirmed during technical review.
Materials, edges and coatings
Coating selection is made together with the carbide substrate, edge sharpness, workpiece grade, coolant and observed wear mode.
Thread whirling or single-point turning?
Both processes have valid applications. The decision depends on part length, profile depth, workpiece support, production volume and the available machine setup.
| Application factor | İplik dönüyor | Single-point thread turning |
|---|---|---|
| Long or slender workpieces | Can cut close to the guide bushing or supported area, helping control deflection. | Suitable when the part is rigid enough and radial cutting forces are manageable. |
| Deep or complex profiles | Custom full-profile inserts can form complex geometry efficiently. | May require multiple passes and careful control of infeed strategy. |
| Multi-start threads | Well suited when machine synchronization and insert design are correctly matched. | Useful for low-volume or flexible production, with additional programming and passes. |
| Prototype or small batch | Practical when a suitable cutter body and insert platform already exist. | Often the simpler starting option when no dedicated whirling tooling is available. |
What should you send for a tooling review?
The most useful starting point is the complete thread or part drawing. A current insert, cutter-body drawing or clear pocket photo can also help confirm compatibility.
Thread whirling insert questions
Practical answers for buyers evaluating a custom insert, replacement tool or new whirling application.
Can ONMY make inserts from a finished thread drawing?
Yes. The complete drawing is reviewed together with the cutter-body pocket, machine setup, workpiece material and thread direction. Pitch alone is not sufficient for a final insert design.
Can you replace an existing whirling insert?
A replacement insert can be evaluated from the original drawing, a usable sample, insert-pocket dimensions and the required finished thread profile. Providing all four gives the most reliable starting point.
Do you support single-start and multi-start threads?
Yes. The number of starts, pitch, lead, hand direction and machine synchronization must be confirmed during the application review.
Which materials can be machined?
Typical applications include titanium alloys, stainless steels and alloy steels. The exact carbide, coating and edge preparation depend on the material grade and cutting conditions.
Do you supply cutter bodies as well as inserts?
Cutter-body supply or development can be discussed based on cutting diameter, insert count, pocket platform and the interface drawing of the whirling unit.
Which information is required for quotation?
Send the part drawing, thread profile, material, machine model, whirling-head information, current tooling and the quality or tool-life problem you want to improve.
