VHM Series ultra precision honing solutions integrate accuracy, performance and reliability in a combined package. These honing solutions are ideally suited for applications in Automotive, Aerospace, Firearm and Defense, Pneumatic, Hydraulic Cylinder and mining industries.

The super fast stroking system combined with Precihole’s high precision tooling produces holes with a mirror finish. Output parameters like straightness, roundness and cylindricity are excellent within submicron levels.

Machine Features
  • Use of hydraulic cylinder for linear reciprocation and servo technology for mandrel expansion
  • Special fixturing for quick component location and clamping
  • 5 micron fine coolant filtration system
  • Mitsubishi / Siemens PLC controls with touch screen HMI
  • User friendly screens and simplified machine operation
  • Air gauging to measure the bore size accurately
