Product Details
CBN Grooving Insert for Hardened Steel and Cast Iron
UHD CBN Grooving Insert is a dedicated superhard cutting tool designed for precision groove machining on hardened steel, cast iron and other difficult-to-machine materials. It is developed for narrow grooves, face grooves and snap ring grooves where groove profile accuracy, edge stability and burr control are important. Manufactured by Henan UHD Ultrahard Tools Co., Ltd, this insert supports both standard procurement programs and drawing-based customization for industrial B2B buyers.
Why Dedicated CBN Grooving Inserts Are Needed
Grooving hardened workpieces places concentrated load on a small cutting edge. Frequent entry and exit, narrow cutting zones and interrupted surfaces can make general-purpose turning inserts less suitable for maintaining a stable groove form.
Small cutting edges may experience impact during interrupted cutting or repeated plunge movements.
Variations in groove width, depth or profile can affect assembly, retaining-ring fit and sealing performance.
Uncontrolled edge formation may increase secondary deburring or finishing work after machining.
Core Design Features for Stable Groove Formation
The UHD CBN Grooving Insert combines groove-oriented geometry with a reinforced clamping concept to support controlled cutting in high-hardness applications. Insert selection should be matched with workpiece hardness, groove tolerance, machine rigidity and holder conditions.
- Specialized groove geometry: designed around narrow-groove, face-groove and snap-ring-groove profiles to support more consistent formed widths and shapes.
- Dedicated clamping structure: helps maintain stable insert positioning and reduces the influence of movement or vibration during machining.
- Micro cutting-edge design: developed to improve edge reliability when machining high-hardness materials with small contact areas.
- Interrupted-cutting adaptability: suitable for continuous cutting and selected intermittent cutting conditions when machine and workholding rigidity are adequate.
Machining Materials and Recommended Operations
Suitable Workpiece Materials
Hardened steel, bearing steel, mold steel, gear steel, gray cast iron, ductile cast iron and powder metallurgy materials. The insert can be applied to hardened materials in approximately the HRC 58–62 range, subject to actual cutting conditions.
Recommended Machining Stage
Primarily intended for semi-finishing and finishing operations where groove dimensional consistency, profile control and reduced secondary finishing are production priorities.
Standard and Custom CBN Grooving Tool Configurations
UHD provides CBN grooving inserts for recurring production requirements and can evaluate non-standard configurations based on part drawings or machining parameters. This approach helps buyers align the cutting tool with the actual groove design rather than adapting the part to a limited standard insert range.
Customization can be considered for groove width, groove depth and tolerance requirements.
Support is available for face grooves, external grooves, snap ring grooves and selected special-profile grooves.
Insert configuration can be reviewed together with toolholder, clamping and machine interface details.
Typical Applications for CBN Groove Machining
CBN Grooving Inserts are used where hardened or cast components require repeatable functional grooves as part of the final machining process.
Face grooves and snap ring grooves.
Retaining-ring grooves and oil grooves.
Cylinder face-groove machining.
Piston ring grooves and driveshaft snap ring grooves.
Machine Setup and Application Boundaries
For best operating stability, use the insert on CNC grooving machines or CNC lathes with secure toolholder clamping, suitable concentricity and sufficient system rigidity. Minimizing vibration is important for preserving edge condition and maintaining groove accuracy.
A Practical Tooling Option for Repeatable High-Hardness Grooves
UHD CBN Grooving Inserts are designed to help manufacturers improve control over high-hardness groove machining, especially where stable profile formation, edge reliability and manageable burr levels matter. As an integrated manufacturer and supplier of superhard cutting tools, UHD supports multi-model and repeat-order programs with standard supply and application-oriented custom tooling for global B2B customers.
