ER collets remain the default workholding system because they offer the best cost-to-performance ratio for holding rotating tools, delivering a runout accuracy of 0.005 to 0.015 mm
The growing role of ER collets in Swiss-type and automatic lathes is driven by their superior runout accuracy, tool-holding rigidity, and quick-change versatility, making them the
For 75% of CNC machining centers under 10,000 RPM, the BT40 tool holder remains the winning choice in 2026 due to its balance of rigidity, tool change speed, and cost per spindle.
The primary drivers of auto lathe collet demand growth in 2026 are the global acceleration of electric vehicle (EV) powertrain production, the reshoring of precision component manu
Round bore collets are the precision workholding component that directly determines the concentricity, repeatability, and cycle time of automatic lathe production. For bar-fed CNC
