MKR Micro Radius Grooving Bars

MKR series solid carbide micro radius grooving bars are designed for machining precision full-radius grooves and smooth relief profiles inside small bores. The precision-ground cutting profile produces controlled groove radii and consistent curved groove bottoms in miniature turned components.

Standard models cover R0.3 to R1.0 mm radii, Ø4 to Ø8 mm shanks and minimum bore diameters from Ø4.1 to Ø8.1 mm. Multiple working lengths are available for shallow and recessed internal grooves, with drawing-based customization available for non-standard profiles and dimensions.

Tool Geometry & Structure

MKR micro radius grooving bar tool structure and model identification

The cutting head uses a full-radius profile in which the standard groove width is twice the specified radius. For example, an R0.5 tool produces a nominal 1.0 mm groove width, while an R1.0 tool produces a nominal 2.0 mm groove width.

Select the working length according to groove position and use the shortest model that can reach the feature. This improves rigidity and helps reduce vibration, tool deflection and profile variation.

Panduan Penamaan dan Pemilihan Alat

Select the suitable MKR micro radius grooving bar according to shank diameter, minimum bore diameter, groove radius, groove width, working length and internal feature position.

Pertanyaan Umum & Unduhan

Pertanyaan Umum tentang Produk

What are MKR micro radius grooving bars used for?
MKR series tools are designed for machining full-radius grooves, curved relief features and smooth profile transitions inside small bores. Typical applications include miniature turned components, sleeves, bushings and other precision internal features.
What is a full-radius internal groove?
A full-radius groove has a curved groove bottom formed by the complete radius of the cutting edge. In the standard MKR range, the nominal groove width is twice the specified cutting radius.
What radius sizes are available for the MKR series?
Standard radius options include R0.3, R0.4, R0.5, R0.6, R0.75 and R1.0 mm. Availability depends on the selected shank diameter and minimum bore size.
What minimum bore diameters can MKR tools machine?
The standard range supports minimum bore diameters of Ø4.1, Ø5.1, Ø6.1 and Ø8.1 mm. Additional clearance may be required depending on the groove location and the complete tool movement.
What materials can be machined with MKR radius grooving bars?
Typical applications include carbon steel, alloy steel, stainless steel, cast iron and selected non-ferrous materials. The coating, edge preparation and cutting parameters should be matched to the workpiece material and machining conditions.

Pertanyaan Umum (FAQ) tentang Seleksi & Pendaftaran

How do I select the correct MKR model?
Select the model according to the required groove radius, nominal groove width, minimum bore diameter, shank diameter, groove position and working length. Use the shortest model that can safely reach the groove.
How are cutting radius and groove width related?
For the standard full-radius MKR profile, the nominal groove width is twice the cutting radius. R0.3 produces a 0.6 mm groove, R0.5 produces a 1.0 mm groove, R0.75 produces a 1.5 mm groove and R1.0 produces a 2.0 mm groove.
Which shank diameter should I choose?
Use an Ø4 mm shank for bores of Ø4.1 mm or larger, Ø5 mm for Ø5.1 mm or larger, Ø6 mm for Ø6.1 mm or larger, and Ø8 mm for Ø8.1 mm or larger. When space permits, a larger shank generally provides greater rigidity.
Which working lengths are available?
The Ø4 mm series is available with 10 mm and 15 mm working lengths. The Ø5 mm and Ø6 mm series are available with 15 mm and 22 mm working lengths. The Ø8 mm series is available with 22 mm and 30 mm working lengths.
How can I improve stability during internal radius grooving?
Use the largest shank diameter permitted by the bore, select the shortest practical working length, minimize tool overhang and confirm the correct center height. Cutting speed and feed should be adjusted according to groove depth, workpiece material and machine rigidity.
How should I check tool clearance before machining?
Check the minimum bore diameter, groove position, internal shoulder clearance and complete cutting and retraction path. A component drawing is recommended when the groove is deep inside the bore or close to another internal feature.

Pertanyaan Umum (FAQ) tentang Pemesanan & OEM

Can you manufacture custom MKR radius grooving bars?
Yes. The groove radius, groove width, groove depth, minimum bore diameter, cutting profile, working length, shank diameter, coating and edge preparation can be customized according to drawings or samples.
What information is required for an MKR quotation?
Please provide the standard model or component drawing, required groove radius, groove width, groove depth, minimum bore diameter, groove position, workpiece material, quantity and any coating or marking requirements.
Can distributors order mixed radii and working lengths?
Yes. Mixed-model orders can be reviewed according to the selected radii, shank diameters, working lengths and available stock. Sample quantities are also supported for application testing.
What is the minimum order quantity?
The standard minimum order quantity is 10 pieces. For mixed sizes or customized tools, the final minimum quantity should be confirmed according to the specifications and production requirements.
Is OEM marking and private-label packaging available?
Yes. Custom model identification, laser logo marking, labels and private-label packaging are available for distributors, tooling suppliers and industrial customers.
What is the lead time for standard and customized MKR tools?
In-stock standard models can usually be dispatched within 1–3 working days after order confirmation. Customized tools require separate lead-time confirmation according to geometry, coating, quantity and drawing approval.
