Tool Holding Machining Logic

The 393.14-25 D140X112 is a critical high-precision component within the Sandvik tool holding ecosystem. Its Machining Logic focuses on eliminating air gaps between the chuck and the cutting tool shank, which is fundamental for achieving maximum Clamping Stability. Constructed from specialized high-elasticity steel, this reduction sleeve ensures an even distribution of Clamping Force. This uniform grip is vital for suppressing micro-vibrations, ensuring consistent Stability and prolonging the edge life of carbide drills and end mills in high-speed CNC environments.

🔥 Core Performance


  • Dynamic Stability: Precision-ground surfaces minimize eccentric forces, ensuring Stability at high spindle speeds.

  • Reinforced Insert Seat: Provides the critical internal support for indexable tool shanks, maintaining Clamping Force under heavy axial load.

  • Improved Chip Control: By stabilizing the tool, it prevents vibration-induced chip clogging, facilitating better Chip Evacuation.

Technical FAQ

Q: Does this sleeve fit all hydraulic chucks?
A: It is designed for D140 standard interfaces. Please verify your chuck’s receiving diameter before installation.

Q: How does it impact hole tolerance?
A: It improves TIR (Total Indicator Reading), which directly translates to better hole Stability and tighter tolerances.
