Lead Screw
Whirling Inserts
Custom tooling for your
thread profile and quality target.
Drawing-based carbide inserts for lead screws, feed screws and non-standard long threads. Selection starts with the complete part geometry and whirling setup.
Start with the part
you need to manufacture.
These application examples guide the tooling review. The finished drawing and available machine setup determine the insert requirements.
Lead Screws
Drawing-based insert review for lead screws used in motion systems, actuators and adjustment mechanisms.
Feed Screws
Profile tooling review for feed screws and long threaded shafts with specific surface and dimensional requirements.
Non-Standard Threads
Custom-profile review for miniature screws, rotor profiles and other special parts considered individually.
Define the profile.
Specify the finished result.
Pitch and nominal diameter are only part of the information. Include the complete geometry, required tolerances and inspection requirements.
Profile, Pitch & Lead
Provide the thread form, pitch, lead, number of starts, hand, flank geometry and relevant radii from the drawing.
Diameters & Threaded Length
Include major and minor diameters, thread depth, threaded length and any restricted tool-access areas.
Accuracy & Surface Requirements
State the specified thread and lead tolerances, surface-finish target, burr requirements and inspection method.
Material Condition & Quantity
Provide the exact material grade, hardness or heat treatment, expected quantity and current production requirement.
Review the insert
and machine setup together.
Insert geometry must be considered with the cutter-body pocket, whirling unit and available workpiece support.
Insert & Pocket
Current insert code, usable sample, locating surfaces, clamping arrangement and pocket dimensions or drawing.
Cutter Body & Whirling Head
Cutter-body geometry, insert arrangement, whirling-head model and machine interface information.
Support & Cutting Conditions
Workpiece holding and support, current process, coolant condition and available setup information.
Carbide, Edge & Coating
Material grade, hardness, observed wear and required surface result guide the review of substrate, edge preparation and coating.
For hardened or other demanding workpiece conditions, include the actual hardness and process requirements so tooling suitability can be assessed for the specific job.
Show us what needs
to improve.
Send the required result together with the current measured result. Drawing details, inspection records and tool or part photos make the review more useful.
The topics below help organize the review. A tooling recommendation depends on the actual thread, material and machine setup.
Profile or lead accuracy is outside the requirement
Provide the drawing, measured deviation, inspection method and relevant tool or setup history. The review may include insert profile, compensation, synchronization, setup and wear.
Surface finish varies along the thread
Identify where the change occurs and include surface measurements or photos. Workpiece support, tool condition, cutting data and chip evacuation may need review.
Chatter, vibration or burrs affect the part
Describe the affected area, material and current setup. Include support and workholding details, tool-edge photos and the required surface or edge condition.
Tool life is short or replacement inserts are difficult to source
For wear issues, provide the insert code, material, cutting conditions and wear photos. For replacement tooling, include the finished thread drawing, insert sample and pocket information.
Before you order.
Start with the thread and application data you already have. Missing details can be confirmed during the review.
Can ONMY review a custom lead screw profile?
Yes. Send the finished part or thread-profile drawing, workpiece material and machine setup. The insert profile and tooling interface are reviewed together.
Can an existing special whirling insert be replaced?
A replacement can be evaluated from a usable insert sample, pocket dimensions and the required finished thread drawing. Matching appearance alone does not confirm interchangeability.
Can the same insert be used for different lead screws?
Compatibility depends on the complete thread geometry and cutter-body setup. Confirm the profile, diameters, pitch or lead, thread hand and locating geometry before changing applications.
What is needed for an initial quotation?
Provide the drawing, material and required quantity. Include the machine, whirling-head and current tooling details, together with any quality or tool-life issue.
