Micro Ball Nose End Mills

Compare NBS, DBS and EBS micro ball nose end mills for small curved features. Review the ball radius, cutting diameter and flute length together, then send AXIMET the complete model and quantities for a quotation.

  • Ball radius and cutting diameter are separate drawing fields
  • NBS, DBS and EBS remain separately identifiable
  • Two-flute models listed in individual series tables
  • Model-by-model quantities for samples and repeat enquiries

Choose the Ball Profile for the Small Feature

A micro ball nose cutter is selected by the rounded working tip as well as its diameter. The ball profile needs to fit the surface being machined, while the cutting length and surrounding tool body must clear the feature.

  • Match ball radius R to the curved feature
  • Check flute length against the intended engagement
  • Review clearance around the larger tool body
  • Keep NBS, DBS and EBS model references separate

Match the Tool to the Feature and Machine Setup

Working Profile

Start with the local surface shape and ball radius. Check the cutter path, neighbouring walls and the smallest curvature the tool must produce before choosing the model.

Access and Holding Conditions

A small rounded tip does not make the whole tool a long-reach cutter. Give the feature depth and shoulder clearance, and distinguish cutting length from overall length.

Workpiece and Cutting Conditions

Include the workpiece grade and condition, machining operation, machine and holder, tool projection and chip-removal arrangement. Coating and cutting-parameter requests need the actual application; a series name or tool colour does not establish suitability.

Ball Contact and Finish Requirement

For a ball nose tool, the engaged working diameter depends on where the surface contacts the ball. Include the path, engagement and surface-finish requirement in a technical enquiry rather than applying a nominal-diameter cutting setting to every pass.

Prepare the Range for Your Machining Customers

Build the enquiry around the required feature and the model dimensions, whether you are replacing a production tool or planning a distributor assortment.

Feature-Led Selection

Start with the local surface shape and ball radius. Check the cutter path, neighbouring walls and the smallest curvature the tool must produce before choosing the model.

Replacement Review

Micro ball nose end mills serve rounded or sculpted features. For a flat working-end requirement, compare the square-end micro end mill range against the part drawing and toolpath.

Assortments and Reorders

List quantities by full model and keep different flute counts and length variants separately identifiable. Attach the approved drawing or item specification to repeat enquiries rather than relying on a shared product title.

Production Equipment for Micro Ball Nose End Mills

Review the equipment alongside the ball radius R, cutting diameter D, flute length Lc, shank diameter d and overall length L required for the selected model. Factory scenes provide context; the ordered geometry and any agreed treatment remain item-specific.

CNC Tool Grinding Cell

CNC tool grinding equipment on the workshop floor.

A tool drawing needs a clear definition of the working profile before a grinding setup is evaluated. For NBS models such as NBS0012 (2 flutes), review ball radius, tip profile and cutting length. Review the small working section at suitable magnification, with the measuring method chosen to avoid damaging the tip.

CNC Grinding Equipment

A row of enclosed CNC grinding machines.

A multi-model order is easier to review when each cutting diameter remains linked to its own drawing and quantity. The NBS catalogue list starts with NBS0012 and contains 9 model records with D entries from 0.1 to 0.9; use the source drawing to confirm units and applicable limits.

Tool Grinding Machine

Enclosed tool-grinding equipment with an operator area alongside.

The relationship between the working edge and the holding section belongs in the dimensional review, not just the overall tool outline. Keep the drawing for NBS0012 and other NBS models attached to the order's ball radius, tip profile and cutting length requirements. Review the small working section at suitable magnification, with the measuring method chosen to avoid damaging the tip.

Automated Tool Grinding Cell

A tool-grinding machine with a robotic handling enclosure.

For a repeat-order programme, keep the approved model and drawing revision together; an automated handling scene does not establish a tolerance guarantee. In the NBS range, use NBS0012 as a model reference when checking ball radius, tip profile and cutting length against the part requirement.

Automated Grinding Equipment

Tool-grinding machines with enclosed robotic handling equipment.

When several geometries appear in one enquiry, separate the item records so the selected cutting profile remains identifiable throughout the order discussion. The NBS catalogue list starts with NBS0012 and contains 9 model records with D entries from 0.1 to 0.9; use the source drawing to confirm units and applicable limits.

CNC Grinding Machines

Enclosed CNC grinding equipment arranged along the workshop aisle.

Compare the required cutting section and clearance envelope when reviewing production requirements; the workshop overview is context for that discussion. Select NBS0012 or another NBS model against the curved surface or local cavity feature.

Cleaning Equipment

A multi-tank cleaning line in the tool production workshop.

Surface cleanliness matters when reviewing a cutting edge or a proposed surface treatment. Specify the condition required for inspection rather than assuming one cleaning cycle suits every tool. Keep the drawing for NBS0012 and other NBS models attached to the order's ball radius, tip profile and cutting length requirements. Review the small working section at suitable magnification, with the measuring method chosen to avoid damaging the tip.

Tool Finishing Workstations

Machine workstations in the tool-finishing area.

The final working profile should be compared with the ordered geometry. Any finishing requirement needs to preserve the dimensions that define the selected tool. In the NBS range, use NBS0012 as a model reference when checking ball radius, tip profile and cutting length against the part requirement.

Cutting-Edge Preparation Equipment

An operator beside a tool honing and polishing machine.

Edge preparation is a specification decision, not an automatic requirement. Discuss whether an edge treatment is appropriate for the selected geometry before adding it to an order. For NBS models such as NBS0012 (2 flutes), review ball radius, tip profile and cutting length.

Edge Honing and Polishing Equipment

An operator beside enclosed tool honing equipment.

Where an edge treatment is requested, define the condition to be assessed without changing the intended cutting profile. This equipment view does not establish a treatment for every model. Select NBS0012 or another NBS model against the curved surface or local cavity feature. Review the small working section at suitable magnification, with the measuring method chosen to avoid damaging the tip.

Wet-Blasting Equipment

Enclosed wet-blasting equipment in the surface-finishing area.

Wet blasting is shown as workshop equipment. Include it in a tool specification only when an applicable surface-treatment requirement has been agreed; it is not a default step for this range. Keep the drawing for NBS0012 and other NBS models attached to the order's ball radius, tip profile and cutting length requirements.

Wet-Blasting Equipment — Additional View

An alternate image of enclosed wet-blasting equipment.

Use this additional equipment view as factory context. Whether a surface-treatment route is appropriate depends on the ordered tool and its acceptance requirements, not on the presence of a machine photograph. In the NBS range, use NBS0012 as a model reference when checking ball radius, tip profile and cutting length against the part requirement. Preserve the specified ball radius, tip profile and cutting length when discussing any optional treatment for NBS.

Tool Coating Equipment

An enclosed tool-coating unit in the workshop.

Choose any coating against the workpiece and the selected tool geometry. Equipment photographs do not identify the coating chemistry or prove a hardness or tool-life rating. For NBS models such as NBS0012 (2 flutes), review ball radius, tip profile and cutting length.

Coating-Area Equipment

Vacuum-chamber equipment in the coating area.

A surface-treatment enquiry should identify the selected model and required finish. Keep the coating requirement separate from dimensional acceptance and from unverified performance claims. Select NBS0012 or another NBS model against the curved surface or local cavity feature.

Laser-Marking Station

An operator working at an enclosed laser-marking station.

State the identification and label information required for the order. Any requested tool marking must be reviewed for the available non-cutting area rather than assumed suitable for every tool size. Keep the drawing for NBS0012 and other NBS models attached to the order's ball radius, tip profile and cutting length requirements. Review the small working section at suitable magnification, with the measuring method chosen to avoid damaging the tip.

Inspection Equipment and Acceptance Requirements

Build the inspection request around ball radius R, cutting diameter D, flute length Lc, shank diameter d and overall length L. Define the measurement features and limits for the selected drawing. Installed runout and balance are separate from a dimensional or visual check.

Tool Inspection Room

Operators working at optical inspection and tool-measuring stations.

A useful acceptance plan identifies the tool features to measure, the required limits and the applicable drawing revision. The inspection-area view does not establish a particular test result. The NBS catalogue list starts with NBS0012 and contains 9 model records with D entries from 0.1 to 0.9; use the source drawing to confirm units and applicable limits.

Cutting-Tool Profile Measurement

An operator positioning a cutting tool at a profile-measuring station.

Profile review should follow the actual working geometry and the dimension definitions on its drawing. Define the feature being assessed before comparing measurements or accepting a sample. For NBS models such as NBS0012 (2 flutes), review ball radius, tip profile and cutting length. Review the small working section at suitable magnification, with the measuring method chosen to avoid damaging the tip.

Measurement Workstations

Optical measuring workstations in the inspection area.

Keep cutting dimensions, holding dimensions and length definitions separate in the inspection request. A measurement image is supporting context, not a substitute for an item-linked result. The NBS catalogue list starts with NBS0012 and contains 9 model records with D entries from 0.1 to 0.9; use the source drawing to confirm units and applicable limits.

Tool Presetting and Dimensional Review

A tool presetter with an optical measuring arm and display.

Tool presetting supports a discussion of length and visible profile. Assess installed runout separately with the agreed holder, projection, position and method; this image alone does not prove runout capability. Keep the drawing for NBS0012 and other NBS models attached to the order's ball radius, tip profile and cutting length requirements. Review the small working section at suitable magnification, with the measuring method chosen to avoid damaging the tip.

Optical Tool Presetter

An optical tool presetter and measurement display.

Agree the dimensional datum and measurement position before comparing presetting information. Overall length, cutting length and installed projection describe different aspects of a tool setup. In the NBS range, use NBS0012 as a model reference when checking ball radius, tip profile and cutting length against the part requirement.

Tool Measurement Setup

An operator setting a tool in an enclosed measuring machine.

Identify the selected tool and the drawing features that need checking. Machine appearance alone cannot establish an inspection resolution, a tolerance limit or a completed result for that item. For NBS models such as NBS0012 (2 flutes), review ball radius, tip profile and cutting length. Review the small working section at suitable magnification, with the measuring method chosen to avoid damaging the tip.

Optical Inspection Workstations

Operators inspecting tools at camera-based inspection workstations.

Define which cutting-edge and tip features need visual review and what constitutes an unacceptable defect. Use a suitable view of the working section rather than judging it from a full-tool photograph. Select NBS0012 or another NBS model against the curved surface or local cavity feature.

Balancing Instrument

A balancing instrument with a protective enclosure.

Balancing equipment is shown as factory context. Balance and runout are different assessments; do not treat this photograph as proof that an individual cutter has been balanced or that its cutting diameter is within tolerance. Keep the drawing for NBS0012 and other NBS models attached to the order's ball radius, tip profile and cutting length requirements. For NBS, any balance requirement needs its own assembly definition and acceptance basis.

Prepare a Clear Quote and Reorder List

Use one line for each series, model and quantity. For a trial order, describe the machining result you need to assess. For a repeat order, include the approved item or drawing revision so the enquiry identifies the same tool.

  • List the complete model code, quantity per model and any required dimensional tolerances.
  • Provide the workpiece, machining operation and machine or holder details for application review.
  • State individual tool protection, label information and outer-pack requirements in the enquiry.
  • Include the destination, required delivery date and any private-label or documentation requirements.

Include the selected model and quantity on each line of the enquiry. Where the same family appears with different flute counts or lengths, retain the complete code and drawing reference.

Request price, packing, order quantity and lead time for the actual model mix. State any marking, individual tool protection and documentation requirements with the enquiry.

Micro Ball Nose End Mills Purchasing FAQ

How do I choose the ball radius for a small curved feature?

Start with the part surface and the radius required by the toolpath. Compare the listed ball radius R and cutting diameter D with the local curvature and adjacent walls. A matching diameter alone does not establish access or the required finished profile.

Can the same-diameter NBS, DBS and EBS models be treated as equivalent?

Keep the three series separately identified. Compare the complete model record, ball radius, cutting length and holding dimensions, then specify the workpiece and any material or coating requirement. Matching dimensions do not establish identical construction, application suitability or cutting behaviour.

Does the nominal micro ball diameter give the cutting speed at every contact point?

No. The engaged portion of a ball tip changes with the cut and surface orientation, so the working cutting diameter may differ from the nominal diameter. Provide the toolpath and engagement for technical review; a nominal diameter alone is not a complete speed recommendation.

What should be checked before approving a micro ball nose trial?

Record the selected model, ball radius and cutting length, then document holder projection, the runout assessment and the actual workpiece and path. Agree the dimensional and surface-finish result to evaluate. The trial needs those conditions to make a later comparison meaningful.

Will a micro ball nose cutter leave a flat-bottomed feature like a square-end tool?

Its rounded working profile differs from that of a square-end cutter. Select the profile against the part drawing and planned path rather than substituting the tool by diameter. For a flat working-end requirement, review the square-end micro tool range separately.

What should a distributor include in a micro ball nose quotation list?

List NBS, DBS or EBS full model codes and quantities separately, together with the required ball radii and lengths. Include the workpiece, application and sample acceptance requirements. Keep any marking, individual protection and delivery requirements attached to that specific assortment.
