SLN

Side Lock with Nut

Side lock clamping mechanism with securing nut

Ø

Inner Bore Diameter (Number)

The bore diameter in mm for clamping your tool

Examples

SLN20 = 20mm bore diameter for clamping tools

SLN32 = 32mm bore diameter for clamping tools

SLN40 = 40mm bore diameter for clamping tools

Usage: Select the SK taper that matches your machine spindle, then choose the SLN bore size that corresponds to your end mill shank diameter.

SK Side Lock End Mill Arbors

SK Side Lock End Mill Arbors are designed for secure clamping of end mills in CNC machining centers using SK taper connections. These arbors feature side lock mechanisms for reliable tool holding and quick tool changes, combined with the robust SK taper interface. Key Features: • SK Taper Interface: SK30, SK40, SK50 configurations for various machine sizes • Side Lock Design: Secure clamping mechanism for reliable tool holding • Multiple bore diameters (SLN): From 12mm to 40mm • High-quality construction for demanding applications • Precision ground surfaces for optimal runout • Fine balanced for high-speed operations • Quick tool changes with excellent repeatability SK Taper Sizes: • **SK30**: 30mm taper, suitable for smaller machines and lighter cutting • **SK40**: 40mm taper, most common size for general purpose machining • **SK50**: 50mm taper, heavy-duty applications and large machines SLN Bore Sizes: • SLN12, SLN16, SLN20, SLN25, SLN32, SLN40 • Covers wide range of end mill diameters • Precision bores for tight tolerances Applications: • End mill holder for face milling and slotting • High-speed CNC machining operations • Precision machining centers with SK taper spindles • General purpose milling applications • Heavy-duty cutting operations • Production machining environments
