MVR Micro Deep Face Grooving Bar Overview

The MVR series is a precision-ground solid carbide micro tool designed for deep face grooving in small bores and restricted internal features. Its extended cutting profile provides access to deeper groove positions, while dual coolant holes direct coolant closer to the cutting zone to support chip evacuation, temperature control and consistent machining performance.

Model Identification Guide

Select the suitable MVR model according to groove width, machining depth, minimum bore diameter, working reach, shank diameter and coolant requirements.

Key Product Advantages

MVR internal micro face grooving bar product advantages
● Deep-Groove Accessibility

The extended cutting profile provides controlled access to deeper face-groove positions and restricted features inside small bores.

● Dual Coolant Delivery

Two coolant holes direct coolant closer to the cutting zone to support chip evacuation, reduce heat accumulation and improve machining stability.

● Solid Carbide Rigidity

The integral solid carbide body provides increased rigidity for deep-groove machining and helps control vibration at extended working lengths.

● Precision-Ground Cutting Edge

Precision-ground geometry supports consistent groove width, controlled cutting action and repeatable dimensional performance.

● Drawing-Based Customization

Groove width, groove depth, working reach, minimum bore, shank diameter, coolant-hole layout, coating and marking can be customized.

Why Choose MVR Deep Face Grooving Bars

Merkmal Conventional Tools MVR Solution
Groove Reach Standard geometry may have limited access to deeper face grooves. Deep-reach profile provides access to recessed groove positions.
Coolant Delivery External coolant may not reach the cutting zone effectively. Dual coolant holes deliver coolant closer to the cutting edge.
Steifigkeit Extended tools may generate vibration during deep grooving. Solid carbide construction improves stability at longer reach.
Groove Consistency Heat and chip accumulation may affect surface finish. Precision-ground geometry and directed coolant support consistent results.

Machining Guidelines

Follow these setup and machining recommendations to improve cutting stability, groove accuracy and tool life when using solid carbide micro face grooving bars.

01. Tool Clamping

Securely clamp the tool before machining and keep the tool overhang as short as possible to reduce vibration and cutting-edge damage.

02. Center-Height Setting

Set the cutting edge on the spindle centerline or up to 0.05 mm below it. Do not position the cutting edge above the centerline.

03. Machining Direction

For face-grooving operations, begin at the larger groove diameter and progress toward the smaller diameter.

04. Chip Evacuation

Apply suitable coolant and maintain effective chip evacuation to prevent chip packing, edge chipping and poor groove finish.

05. Cutting Method

Use the tool for controlled radial face-grooving operations. Avoid lateral cutting or side turning unless the tool geometry is specifically designed for it.

06. Initial Cutting Parameters

Where machining conditions allow, begin with a cutting speed of 40 m/min or higher and keep the feed rate within 0.05 mm/rev.

Parameter Note: Actual cutting parameters should be adjusted according to the workpiece material, groove diameter, tool overhang, coating, coolant supply and machine rigidity.

Product FAQs
What are MVR micro deep face grooving bars used for?
MVR series tools are designed for deep face grooving and axial grooving inside small bores. Their V-type geometry provides additional clearance for reaching recessed face grooves and narrow internal features.
What standard groove widths are available?
The standard MVR range includes groove widths of 2.0 mm, 2.5 mm, 3.0 mm and 4.0 mm. Available widths depend on the selected shank diameter and model.
What is the minimum bore diameter for the MVR series?
MVR tools with a 6 mm shank require a minimum bore diameter of 12 mm. Models with an 8 mm shank require a minimum bore diameter of 16 mm.
What working lengths and overall lengths are available?
The 6 mm shank series is available with 10 mm, 15 mm and 22 mm working lengths and a 50 mm overall length. The 8 mm shank series is available with 15 mm and 22 mm working lengths and a 60 mm overall length.
What is the advantage of the dual coolant holes?
The dual coolant holes direct coolant toward the cutting zone, helping remove chips from deep grooves, reduce cutting heat and improve cutting-edge stability during continuous production.

Selection & Application FAQs

How do I select the correct MVR model?
Select the model according to the minimum bore diameter, required groove width, working length and overall tool reach. Use the shortest working length that can safely reach the groove to maintain maximum rigidity.
Which models are suitable for a Ø12 mm bore?
For a bore diameter of 12 mm or larger, select from the 6 mm shank models. Standard options include 2.0 mm and 2.5 mm groove widths with 10 mm, 15 mm or 22 mm working lengths.
Which models are suitable for a Ø16 mm bore?
For a bore diameter of 16 mm or larger, the 8 mm shank models provide increased rigidity. Standard groove widths include 3.0 mm and 4.0 mm with 15 mm or 22 mm working lengths.
When should I choose a 10 mm, 15 mm or 22 mm working length?
Choose 10 mm for shallow and easily accessible grooves, 15 mm for medium-depth applications and 22 mm for deeper recessed grooves. Avoid selecting a longer tool than the application requires.
How can I improve stability during deep face grooving?
Use the largest shank diameter permitted by the bore, keep tool overhang as short as possible, confirm the tool center height and apply sufficient coolant. Reduced feed and staged cutting may be required for narrow or deep grooves.

Ordering & OEM FAQs

Can you produce non-standard MVR face grooving bars?
Yes. Custom groove widths, cutting lengths, shank diameters, tool profiles and overall dimensions can be manufactured according to drawings, samples or machining requirements.
