MGR Carbide Micro Internal Grooving Bar Overview
MGR Series solid carbide micro internal grooving bars are designed for machining precision grooves and narrow recesses inside small-diameter bores. The standard range covers actual cutting diameters from Ø2.9 mm to Ø7.9 mm, with groove widths from 0.5 mm to 3.0 mm.
The one-piece fine-grain solid carbide construction provides the rigidity required for small-bore CNC turning. Precision-ground cutting geometry helps maintain groove width, groove depth and surface quality when machining compact precision components.

Selection & Setup Guidance
Bore clearance: Confirm that the actual bore diameter is larger than the tool cutting diameter d1 and that sufficient radial clearance is available.
Groove dimensions: Select groove width B and depth Q directly from the size table. Do not exceed the listed standard groove depth.
Tool overhang: Use the shortest practical overhang and the largest shank diameter permitted by the component geometry.
Center height: Set the cutting edge accurately on the spindle centerline to reduce uneven cutting forces and edge damage.
Coolant and chip control: Direct coolant toward the cutting zone and confirm that chips can leave the groove without becoming trapped inside the bore.

Pertanyaan Umum & Unduhan
Pertanyaan Umum tentang Produk
What are MGR micro internal grooving bars used for?
MGR Series solid carbide bars are designed for machining precision grooves, relief grooves and narrow recesses inside small-diameter bores. Typical applications include sleeves, bushings, hydraulic components, instrument parts and other precision-turned components.
What bore sizes can the MGR Series machine?
The standard range includes MGR3.0, MGR4.0, MGR5.0, MGR6.0 and MGR8.0 size classes. Their actual cutting diameters are Ø2.9, Ø3.9, Ø4.9, Ø5.9 and Ø7.9 mm respectively. The workpiece bore must provide sufficient clearance for the selected tool and its complete cutting path.
What groove widths are available?
Standard groove widths range from 0.5 mm to 3.0 mm. The available width depends on the selected tool size: MGR3.0 starts from 0.5 mm, while the larger MGR8.0 models are available in widths from 1.5 mm to 3.0 mm.
What groove depths can be machined?
Standard groove depths range from 0.8 mm to 3.0 mm. The maximum depth depends on the cutting diameter and groove width. For example, MGR3.0 tools have a standard depth of 0.8 mm, while selected MGR8.0 tools can machine grooves up to 3.0 mm deep.
What materials can be machined with MGR grooving bars?
The MGR Series is primarily suitable for carbon steel, alloy steel, stainless steel and copper alloys. It can also be used for pre-hardened steel, hardened steel below approximately 48 HRC, cast iron and selected titanium alloys when the coating, edge preparation and cutting conditions are correctly matched.
What machines are compatible with MGR internal grooving bars?
MGR tools can be used on CNC turning centers, Swiss-type CNC lathes, automatic lathes and other precision turning machines equipped with a suitable tool holder or clamping sleeve.
Pertanyaan Umum (FAQ) tentang Seleksi & Pendaftaran
How do I select the correct MGR model?
First confirm the bore diameter and select an MGR cutting diameter that provides sufficient clearance. Then select the required groove width B, groove depth Q and clearance length L1. The shank diameter must also match the available holder or clamping sleeve.
What is the difference between cutting diameter d1 and shank diameter D?
The cutting diameter d1 determines whether the cutting section can enter the bore. The shank diameter D is the cylindrical section held by the tool holder. For example, an MGR3.0 tool has an actual cutting diameter of Ø2.9 mm but uses a Ø4 mm shank.
How do I select the clearance length L1?
The clearance length must be long enough to reach the groove position without the larger tool body contacting the bore. Standard L1 lengths are 10, 15 and 20 mm. Use the shortest length that can safely reach the groove because a shorter overhang generally provides better rigidity.
How can I improve machining stability in a small bore?
Use the largest possible shank, keep the tool overhang as short as practical and set the cutting edge accurately on the spindle centerline. The holder must clamp the complete shank securely. Cutting speed and feed should be adjusted according to groove width, material hardness and machine rigidity.
How should coolant and chips be managed during internal grooving?
Direct coolant toward the cutting zone whenever possible and verify that chips can leave the groove and bore freely. Trapped chips can damage the groove surface or cutting edge. For restricted or deeper grooves, a pecking strategy may improve chip evacuation.
Can the tool cut sideways to widen an internal groove?
Standard MGR bars are primarily intended for radial plunging to produce the specified groove width. Lateral turning should only be used when the selected cutting geometry and application have been confirmed for that operation. For a wider groove, multiple controlled plunges or a custom-width tool is normally recommended.
Pertanyaan Umum (FAQ) tentang Pemesanan & OEM
Can you manufacture custom MGR internal grooving bars?
Yes. Cutting diameter, groove width, groove depth, corner radius, clearance length, shank diameter, overall length, coating and cutting geometry can be customized according to component drawings or reference samples.
What information is required for an MGR quotation?
Please provide the standard model or product code, bore diameter, groove width, groove depth, groove position, workpiece material, required quantity and any coating requirements. A component drawing is recommended when the groove is close to an internal shoulder or clearance is limited.
Can I order mixed models for initial testing?
Yes. Small trial orders and mixed standard sizes can be reviewed according to current stock and production availability. The standard minimum order quantity is 10 pieces.
Do you provide private-label and OEM packaging?
Yes. Custom laser marking, model identification, labels and private-label packaging are available for distributors and tooling resellers. Please provide the logo file and packaging requirements when requesting a quotation.
What is the lead time for MGR grooving bars?
In-stock standard models can usually be dispatched within 1–3 working days after order confirmation. Lead time for customized tools depends on the dimensions, cutting geometry, coating, quantity and packaging requirements.
