Features of NT-ER Collet Chucks

Vacuum Quenching for Enhanced Durability

The NT-ER collets undergo vacuum quenching treatment, a process that significantly increases hardness while maintaining strong toughness. This treatment ensures the collets can withstand heavy impacts and loads, making them suitable for high-intensity machining operations. The enhanced fatigue resistance extends the tool’s lifespan, reducing downtime and maintenance costs.

Monolithic Structure for Superior Rigidity

Designed with an integral structure, the NT-ER collet chucks distribute pressure evenly across the precise needle roller of the cage. This design minimizes vibration and deflection during operation, ensuring consistent performance even during large-volume cutting tasks. The monolithic construction also enhances structural integrity, making it a reliable choice for heavy-duty applications.

Full Grinding for Optimal Precision

Every NT-ER collet chuck undergoes overall full grinding, a meticulous process that ensures the shaft and cone hole are perfectly aligned. This precision grinding protects the drive head’s connection, maintaining accuracy and reducing wear over time. The result is a tool holder that delivers exceptional centering accuracy, critical for high-speed machining.

Fine Grinding for Aesthetic and Functional Excellence

The exterior of the NT-ER collet chucks is brightly polished, combining aesthetic appeal with functional benefits. The finely ground shaft hole ensures smooth operation and precise tool alignment, enhancing overall machining accuracy. This attention to detail reflects SHANDONG OLI MACHINERY’s commitment to quality and craftsmanship.

Wear Resistance and Stability

Crafted from high-quality 40Cr alloy steel, the NT-ER collet chucks offer superior wear resistance and long-term stability. This material choice ensures consistent performance even under extreme conditions, making it a dependable solution for CNC machining and engraving applications.
