MFR Anti-Vibration Micro Face Grooving Bar Overview
MFR series solid carbide micro face grooving bars are designed for machining narrow face grooves and recessed features in small bores. The rigid carbide construction and anti-vibration design help control deflection and chatter when tool access is restricted, supporting consistent groove dimensions and a stable surface finish on CNC turning and Swiss-type machines.
Small-Bore Face Grooving Applications
The MFR series is intended for precision face-grooving operations where the groove is machined on an internal end face or recessed face inside a component. Select the tool according to the groove diameter, groove width, machining depth, working reach and available clearance.
| Applicazione | Machining Requirement | Selection Focus |
|---|---|---|
| Small-Bore Face Grooving | Narrow grooves on an internal end face | Minimum groove diameter and groove width |
| Recessed Face Machining | Grooves located behind a shoulder or inside a recess | Working reach, neck clearance and tool orientation |
| Precision Groove Finishing | Controlled groove width, depth and surface finish | Edge geometry, runout and machine rigidity |
| Custom Small-Part Features | Non-standard face grooves based on component drawings | Drawing dimensions, material and tolerance |
Key Product Features
Workpiece Materials
Tool geometry, coating and cutting conditions should be matched to the workpiece material and groove dimensions.
| Gruppo di materiali | Applicazioni tipiche | Machining Note |
|---|---|---|
| Carbon & Alloy Steel | Precision shafts, sleeves and mechanical components | Use stable clamping and material-matched coating |
| Acciaio inox | Medical, fluid-control and precision industrial parts | Maintain reliable coolant delivery and avoid rubbing |
| Ghisa | Small housings and general machinery components | Confirm grade, edge preparation and dust control |
| Non-Ferrous Materials | Aluminum, copper alloys and precision fittings | Use a sharp geometry selected for the specific alloy |
Selection & Machining Notes
- Confirm the minimum groove diameter, groove width, radial groove depth and axial location before selecting a model.
- Use the shortest practical tool overhang to maximize rigidity and reduce vibration.
- Check neck clearance and cutting direction to prevent interference with the bore wall or shoulder.
- Direct coolant toward the cutting zone to support chip evacuation and temperature control.
- Custom groove widths, working lengths, cutting geometries, coatings and laser marking are available according to drawings.

FAQ & Downloads
Product FAQs
What are MFR micro face grooving bars used for?
MFR series solid carbide bars are designed for machining narrow face grooves and recessed features inside small bores. They are suitable for precision components produced on CNC turning centers and Swiss-type lathes.
What standard groove widths are available?
Standard groove widths range from 0.75 to 3.0 mm. Available widths include 0.75, 1.0, 1.5, 2.0, 2.5 and 3.0 mm, depending on the selected shank diameter and model.
Which shank diameters and working lengths are available?
The standard MFR range includes Ø4, Ø5, Ø6 and Ø8 mm shanks. Effective working lengths L1 are 15, 22 and 30 mm, while overall lengths are 50 or 60 mm according to the model.
What cutting depths and corner radii are available?
The F dimension ranges from 1.7 to 6.0 mm across the standard models. Standard cutting-edge corner radii are R0.05 mm for the smaller Ø4 and Ø5 mm tools and R0.10 mm for the Ø6 and Ø8 mm tools.
What does the anti-vibration design improve?
The rigid solid carbide construction and optimized tool geometry help reduce deflection and chatter during restricted small-bore face grooving. This supports more consistent groove dimensions, cutting stability and surface finish.
What workpiece materials can MFR tools machine?
MFR tools can be supplied for carbon steel, alloy steel, stainless steel, cast iron and selected non-ferrous materials. Cutting geometry, coating and machining parameters should be matched to the specific workpiece material.
Selection & Application FAQs
How do I select the correct MFR model?
Start with the required groove width, then confirm that cutting depth F is sufficient. Select the shortest L1 that reaches the groove and match shank diameter D to the holder or precision bushing. Also check bore clearance and tool orientation before machining.
How is the model MFR 6B2.0 L22-D6 interpreted?
MFR identifies the product series, B2.0 indicates a 2.0 mm groove width, L22 indicates a 22 mm effective working length and D6 indicates a 6 mm shank diameter. This standard model has an F dimension of 3.8 mm and an R0.10 mm corner radius.
How can I improve stability during small-bore face grooving?
Use the shortest practical tool overhang, clamp the carbide shank securely, minimize runout and direct coolant toward the cutting zone. Start with conservative cutting conditions and increase them only after confirming stable chip evacuation and groove quality.
Can MFR tools be used for deep face grooves?
The MFR series covers F dimensions up to 6.0 mm. For deeper face grooves or applications requiring greater radial reach, the MVR micro deep face grooving series may be more suitable. Tool selection should be confirmed from the component drawing.
Ordering & OEM FAQs
Can you manufacture customized MFR face grooving bars?
Yes. Custom groove widths, cutting depths, corner radii, effective lengths, shank dimensions, cutting geometries and coatings can be produced according to drawings, samples or machining requirements.
What information is required for an accurate quotation?
Please provide the required model or groove width, cutting depth, groove position, bore dimensions, workpiece material, quantity and machine type. A component drawing or reference sample is recommended for customized tools.
Do you support small trial orders and mixed models?
Yes. Small trial orders and mixed standard models can be discussed for distributor evaluation and machining tests. The standard minimum order is 10 pieces, subject to model availability and order combination.
What is the lead time for MFR 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 packaging requirements.
