For Valve Body Cutting PCD Rotating Tools
Automotive Components
Valve body spool hole machining is one of the most dif cult types of machining. Hole nishing, which involves both interrupted cutting and multi-stage machining, requires high machining accuracy in quality issues such as surface roughness, circularity, cylindricity, and coaxiality. A.L.M.T. proposes ideal tool designs based on various machining experience.
Features D A single reamer can nish multi-stage holes, reducing work processes. D Delivering an excellent surface nish unobtainable with carbide tools. D Precise and stable dimensional and shape accuracy unique to diamond tools can be maintained for a long time. D Cutting speed and feed can be tuned to reduce machining time.

Tool Lineup for Valve Body Machining
1 ute 4-stage PCD Reamer Single- ute multi-stepped design realizes high circularity and coaxiality.
4 ute 4-stage PCD Reamer with Leading Edge With a leading edge added to each cutting edge, position deviation from the previous process is prevented, the result is high-precision hole nishing at high feed conditions.
4 ute 3-stage PCD Drill Medium nishing for pre-cast hole drilling, high feed and high-accuracy prepared hole drilling are possible.
5 ute Irregular Pitched 3-stage PCD Reamer With irregular pitched cutting edges,
2 ute 4-stage PCD Drill Medium nishing for deep hole drilling, multi-step machining improves nished coaxiality.
vibration (resonance) during machining is suppressed and circularity and cylindricity are improved.
Various additional function proposals

Chip evacuation function Single cutting edge with a chip discharge groove in the guide pad section prevents adhesion to the cutting edge, thus preventing quality deterioration.
Chip breaking function Addition of a chip breaking function to the cutting edge prevents quality deterioration due to machining defects and machine stoppage due to chip entanglement onto the holder.
Workpiece chipping prevention function The area around the hole exit is weak, cutting forces may cause chipping of the workpiece along with chips or ring-shaped chips that can wrap around the workpiece. This can be prevented by a cutting edge design that suppresses cutting resistance.
