Boring bar S32U CKUNR (CKUNR for KNUX Indexable Inserts) — right‑hand, 32 mm shank, 350 mm overall length

The boring bar S32U CKUNR is a right‑hand internal turning tool designed for use with KNUX 1604 indexable inserts, suitable for medium to heavy finishing operations on CNC lathes

• High rigidity 32 mm shank
• Compatible with KNUX 1604 inserts
• 350 mm overall length for deep bores
• Right‑hand cut direction

Increased stability for accurate internal turning

A solid design with a 32 mm shank and a mass of 2.264 kg reduces vibration and runout for more consistent bore diameters. The tool's geometry, including the cutting angle of 93°, improves insert support and chip flow, which together enhance surface finish and dimensional repeatability. For workshops aiming to reduce rework, the emphasis on mechanical stability translates directly into fewer rejects and shorter cycle‑time variance.

Designed for fast insert changes and continuous production

Compatibility with KNUX 1604 indexable inserts simplifies maintenance and minimises downtime: worn edges are replaced quickly rather than regrinded, improving throughput. The S32U CKUNR specification denotes a standard interface that integrates cleanly with common clamp systems, while the 52 mm cutting height and 40 mm nominal diameter provide a balance between cutting capacity and access in constrained bores. These features support efficient shift planning and predictable tool life.

Practical fit for a range of machining tasks

With a 350 mm overall length, this boring bar reaches deeper bores without compromising stiffness, making it suitable for internal finishing and light roughing on medium‑sized components. The right‑hand cutting direction suits conventional lathe setups and simplifies programming for automated sequences. As a result, production engineers find it easier to specify this bar where dependable, repeatable internal turning is required with indexable insert convenience.

FAQ

Which inserts fit this boring bar?
The boring bar accepts KNUX 1604 indexable inserts; the CKUNR mounting form matches the insert pocket and clamp geometry used for that series.

Is the bar suitable for deep‑bore applications?
Yes, the 350 mm overall length of the RK754TM boring bar offers reach for deeper bores while retaining practical stiffness for finishing operations.

What is the shank size and why does it matter?
The tool has a 32 mm shank, which provides increased rigidity compared with smaller diameters and helps to reduce vibration and dimensional deviation in internal cuts.

Can this bar be used for roughing as well as finishing?
The design is appropriate for light roughing and finishing; pairing the bar with the correct KNUX grade insert allows adaptation to either higher material removal rates or superior surface quality.

Which cutting direction does the tool use?
This model is specified for right‑hand cutting, compatible with standard CNC lathe programmes and tool cycles.
