Lynx 220 Series

High Productivity Turning Center

The Lynx 220 series is an accurate, high-productivity turning center designed with ultra-fast rapids and high-speed turret indexing, providing greater value and cost performance.

High-Speed Structure

Lynx 220M [LM] Ø250 x 290 [510] mm
Lynx 220LMSA / LMSC Ø300 x 510 mm

Core Machine

Lynx 220 uses FEM analysis to design a stable body. The heavily ribbed torque tube design prevents twisting and deformation. All guideways are wide wrap-around rectangular types for unsurpassed long-term rigidity and accuracy.

Rapid Traverse

Roller-type LM Guide is mounted on the machine to improve rigidity and feed rates. Each axis is powered by a maintenance-free digital AC servo motor. These high-torque drive motors are connected to the ball screws without intermediate gears for quiet and responsive slide movement with virtually no backlash.

X-axis: 30 m/min
Z-axis: 36 m/min
B-axis (Lynx 220 / M): 30 m/min

Main Spindle

The C-axis is positioned in degree increments. Through spindle synchronization with the X and Z axes, three-dimensional contouring, complex, and prismatic machining can be accomplished.

Headstock and Spindle

The headstock and main spindle are manufactured in a temperature-controlled environment, then assembled and tested in our clean room. The heavy-duty cartridge-type spindle is supported by a triple-row angular ball bearing in the front, with a cylindrical roller bearing in the rear. This combination of bearings is very effective in restraining thermal displacement of its front nose and improving high-speed performance and rotational precision.

High Productivity

2-axis Servo Turret A / B / C

Rigidity and efficiency provide increased machine performance. The heavy-duty turret features a large 210 mm diameter curvic coupling and 39 kN of hydraulic clamp force. The heavy-duty design provides unsurpassed rigidity for heavy stock removal, fine surface finishes, long boring bar overhang ratios, and extended tool life.

All turret rotations are controlled by a high-torque servo motor, and turret indexing is non-stop bi-directional, with a second station-to-station index time.

Index Time: 1-station index
Number of Tool Stations

BMT Turret MA / MC / LMA / LMC / LMSA / LMSC

The BMT turret makes it possible to complete complicated parts requiring many tools in just one setup. Reliable servo-driven turret reduces the total cycle time required to machine parts.

Index Time: 1-station index
Power: kW HP

Tailstock

Widely spaced guideways and the heavy-duty design of the tailstock body ensure ample rigidity. The tailstock body is positioned by a traction bar, which engages with the carriage. The traction bar movement and hydraulic body clamping are manual.

Tailstock Specifications

Tailstock Travel: 550 mm
Tailstock Quill Diameter: 65 mm
Taper Hole of Tailstock Quill: MT4 (Live Center)
Tailstock Quill Travel: 80 mm

Sub-Spindle

The travel time of the workpiece is minimized because the travel of the workpiece between both spindles is carried out under a state of revolution through synchronized control of revolution speed. In addition, the cutting performance is enhanced because of the cross-sectional adhesion of the workpiece at the axis.
