Precihole VHM Series โ€“ Vertical Honing Machines

Preciholeโ€™s VHM Series Vertical Honing Machines are NextGen solutions that provide state-of-the-art features and world class performance packaged with ultra-precision honing solutions that integrate accuracy, performance and reliability. They are designed to hone holes from โˆ…5mm (0.2โ€ณ) to โˆ…50mm (2โ€ณ), and part lengths of up to 1500mm (60โ€ณ) long. High precision barrel manufacturing requires the bore to be honed to precision before rifling. The surface pattern, surface finish and taper ovality achieved on these machines is excellent. Precihole vertical honing machines incorporate all the features necessary to upgrade the quality of gun barrels to make them the highest of precision. Honing solutions offered by Precihole are complete solutions comprising of the machine, tooling, tooling accessories as well as recommendations on honing oil suited for this fine machining operations.

Machine Features:

  • All electric servo motors for linear motion, spindle rotation and tool expansion
  • Precision manufactured vertical column to support single or multiple spindles
  • Operator-friendly self-learning controls with custom screens
  • 5 Micron fine coolant filtration systems with oil chilling and magnetic separator for optimal performance
  • Optional air gauging systems for automatic size control
  • Quick change linear indexing table and part loading fixtures
  • Double-expansion technologies for larger diameter holes
