Precihole’s SBN Series Skiving and Roller Burnishing Machines are built to operate in a high production mode for sizing and polishing hydraulic cylinder tubes. Machines incorporate use of state of the art technology that enables cycle times to be 30-40 times faster than honing. Machines are customized to suit volume requirements and provide excellent surface finish and wall thickness consistency across the length of the tube. These machines are complete solutions that include features needed for continuous and repeatable performance over many years.

Machine Features
  • Rigid and Robust design to allow precise and vibration free movement of machine elements
  • Use of ball screw or rack and pinion with servo drives for linear motion
  • Multiple tool steadies to provide tube support
  • Hydraulic vice clamping for clamping tubes
  • High pressure coolant and fine filtration system
  • Oil chilling and Automatic Lubrication
  • Fanuc / Siemens CNC controls with customized screens for monitoring machine parameters
