The Smartbore Plus system offers precision performance, allowing operators to achieve bore sizes accurately and quickly, with no clamping/unclamping.

This range of digital boring heads will enable micron accurate adjustments between 15-68mm on diameter.

  • SB-M15 — 15mm (0.5090") — 18.5mm (0.728")
  • SB-M18 — 18mm (0.709") — 22mm (0.866")
  • SB-M20 — 20mm (0.787") — 31mm (1.220")
  • SB-M30 — 30mm (1.181") — 41mm (1.614") — (in development)
  • SB-M40 — 40mm (1.574") — 51mm (2.007") — (in development)

Rigibore has incorporated its patented Smartbore technology into a superiorly designed, flexible adjustment system with both coarse and fine adjustment capabilities.

Key Benefits

  1. Micron accurate adjustment by using the standard Smartbore Adjuster
  2. Precise adjustment over a range of bore sizes is possible by means of the coarse adjustment feature
  3. Digital fine adjustments are made with the need for clamping/unclamping
  4. Different holders to support insert geometries (and also back boring) can be purchased separately

All boring heads will feature replaceable 'insert holders' for boring that support the following inserts:

  • SB-M15 — CC04T0
  • SB-M18 — CC06/TP08
  • SB-M20 — CC06/TP08

The range of Smartbore Plus heads will cover bore sizes from 15mm (0.590") upwards on diameter.

Dynamic Adjustment Capabilities

The coarse adjustment capability will allow the tool to be set quickly and accurately across a range of bore sizes. Each boring head offers at least 3.5mm of coarse adjustment on diameter.

Micron accurate fine adjustment will ensure precision by using the digital Smartbore Adjuster.

Coarse and fine adjustment measures combine to offer flexibility and accuracy in setting different bore sizes.

Adjustment Procedure

  • Adjust the coarse adjustment locking screw
  • Use coarse adjustment screw to set the approximate size requirement
  • Set and maintain the precise size by using the digital Smartbore Adjuster
  • The internal position sensor is activated when the Smartbore Adjuster is engaged
