BIG KAISER EWN - 20 ~ 203mm Finish Boring Heads

Multifunctional for highest precision and efficiency.

The EWN single insert boring tool program for finishing covers an impressive diameter range with only seven precision boring heads. Each head has a large work range due to three different insert holders for each boring head. The insert holder can be mounted in the opposite direction for an easy changeover to back boring.

Features & Benefits:

* 1 Micron vernier is included to the easy-to-read scale of 0.01mm/diameter increments
* The pre-balanced design acheives stable machining accuracy
* Back boring is available as standard, expanding versatility
* Through Coolant
* Highest accuracy, purely radial cutting edge adjustment by means of a ground and play-free micrometer spindle
* High quality coated tool body for complete protection against corrosion

BIG Daishowa's FCM "Fullcut", is the indexable endmill that combines sharpness and rigidity achieving peformance of solid carbide endmills.

BIG KAISER RW - 25 ~ 150mm Rough Boring Heads

BIG RW twin cutter boring heads are designed for heavy duty rough boring and semifinishing operations. Their compact, sturdy design and postive geometry allow almost chatter-free operation even in interrupted cuts and high cutting speeds. Twin cutter boring heads can outperform single cutter finishing heads by a factor of up to 4 times. Large stock allowances and high feed rates permit high production while assuring optimum bore roundness and location, two important quality features for todays tighter control of part geometry. In many cases, these tools can eliminate the need for semi-finishing cuts due to the superb balance of cutting forces, even under the most severe casting core shift.

BIG RW tool use ISO standard inserts with postive cutting geometry for reduced cutting forces. The top clamp free mounting of the inserts and wide open chip spaces between the insert holders allows perfect chip formation and evacuation. Different grades and geometries of carbide and silicon nitride inserts are available to optimise all application criteria.

Features & Benefits:

* Axial adjustment mechanism achieves "perfect balance cutting"
* The "step cutting method" can reduce the number of passes in the application with a large stock allowance
