SMEC Double 90° Single-Side Twin-Spindle Driven Tools

Name: Mongtec SMEC Double 90° Single-Side Twin-Spindle Driven Tools
Brand: Mongtec

Double 90° single-side twin-spindle holders place two radial spindles on the same side of one station — two cross holes at a fixed pitch in one plunge. Mongtec Precision, a Taiwanese tooling brand headquartered in Taichung, Taiwan, builds them to mount on SMEC turrets.

Developed specifically for SMEC (Samsung Machine Tools) multitasking centers equipped with Y-axis functionality. Featuring a single-side twin-spindle offset design, this toolholder allows for two tools to be configured in a single station for lateral machining. By utilizing the precise Y-axis stroke of the SMEC machine, it significantly enhances tool configuration flexibility and production efficiency per setup, helping customers maximize output within limited turret space.

Build features

Single-Side Twinspindle Efficiency — Provides two same-direction output spindles at a single turret position. Combined with SMEC's Y-axis functionality, it enables rapid tool switching or different diameter lateral operations to maximize productivity per station.
Extreme Runout Accuracy ≤ 0.003mm — High-precision internal manufacturing ensures consistent rotational accuracy across both output spindles, meeting the demands for strict dimensional tolerances and high-quality surface finishes.
High-Rigidity Reinforced Housing — The reinforced housing handles the combined cutting loads from dual-tool operations, demonstrating excellent vibration damping to protect the high-precision drive system of the SMEC turret and ensure long-term stability.
Precision Paired-Ground Spiral Bevel Gears — Achieves smooth power transmission through high-quality ground gears, featuring low noise and minimal heat generation to ensure operational longevity in high-intensity continuous production environments.
Seamless SMEC Y-Axis Compatibility — Fully compliant with SMEC OEM turret and Y-axis offset specifications (such as SL and PL series), ensuring easy installation and precise positioning to help customers achieve high-efficiency, multi-tasking production.

Getting the right holder

The machine model alone does not decide the holder. The same model can leave the factory with different turrets — station count, model suffix and key arrangement all change the mounting. Tell us the machine, the turret and the operation and we confirm the mounting before quoting.

Already using another brand? Send the drawing or the article number of the holder you run today and Mongtec will convert it to an equivalent Mongtec holder — same mounting, same reach, same output.
