PCD/PCBN Grooving Tool
PCD grooving tools are suited to aluminum piston ring grooves, helping reduce chip adhesion during high-speed cutting. Tool geometry can be customized for groove width, depth, bottom profile and machine interface.

A Material-to-Process Tooling Logic
1. Material Selection
PCD for aluminum alloy; CBN for ductile iron or hard iron-based areas.
2. Geometry Matching
Grooving edge form and chip-control structure match ring width, depth and bottom profile.
3. Bore Process Control
Drilling and reaming are matched to manage allowance and final pin bore quality.
4. Line Integration
Tool structure and parameters are adapted to equipment interface, rigidity and takt time.

CBN Grooving Insert for Iron-Based Areas
For ductile iron pistons or hard material zones, CBN grooving inserts are configured around wear resistance, edge stability and groove-profile retention in continuous or interrupted cutting.
Reaming & Drilling Tools
A coordinated drilling and reaming sequence supports piston pin bore machining by controlling pre-machining allowance, final diameter, roundness and bore surface consistency.
Process Value for Piston Manufacturing
- Ring Groove StabilitySupports control of groove width, depth, profile and surface quality through material-appropriate grooving solutions.
- Pin Bore ConsistencyUses coordinated drilling and reaming tooling to improve repeatability of critical bore machining.
- Production RhythmReduces unnecessary repeat passes, tool changes and adjustment time through process-oriented tool design.
UHD solution scope: PCD/CBN insert selection, non-standard grooving and forming tools, drilling and reaming tools, machining parameter guidance, tool refurbishment and ongoing application optimization for global B2B manufacturing customers.
