Large Diameter Boring System
Selecting a Large Diameter System (Above 6” 152.4mm)
Step 1.
Select taper shank or boring ring holder based on machine taper and bore projection.
Step 2.
Select extension and/or modular flange based on taper and/or projection required.
Step 3.
Select extension base based on bore diameter.
Step 4.
Select finish head or roughing system.
Step 5.
Rough boring only. Select rough insert holder based on insert geometry and bore diameter.
Step 6.
Select finish boring head (recommended) or optional finish boring unit (use when counterbalance is required).
Step 7.
Select insert based on insert holder, workpiece material and finish.
Rough Boring Units
- Independent height and diameter setting permit balanced cutting resulting in almost perfectly round holes from the beginning, irrespective of core shifts.
- Two height balanceable cutting edges with metal removal at rates almost 4 times that of a single cutter.
- Height adjustments are made with a cam that supports the insert holder where needed, at the furthest radial point.
- Each insert holder can be adjusted individually in diameter with a dial screw for fast, easy set-up operations.
- Balanced or stepped cutting can be done with the same set of insert holders permitting heavy stock removal and eliminating the need to purchase two sets of insert holders.
- ISO standard inserts eliminates the need for special expensive inserts.
- Mounting flange provides two orientation positions at 90° to one another, thus eliminating the need to purchase special components to clear the tool chain.
Finish Head
- A .0001” vernier is standard on all heads eliminating the need to buy expensive .0001” heads.
- Micrometer spindle provides .001” per dial graduation for fast, accurate set up and adjustment, and reduced scrap.
- No movement between lock and unlock eliminates settling errors common to other systems.
- Well balanced, fully encased in head tool carrier can be run at high speeds.
- Through-spindle coolant capability is standard.
- Replacement insert holder allows for inexpensive pocket replacement and changing of pocket geometry.
