Turning Center has tool setter with4-position touch sensor.

Press Release Summary:




Offered in 3 models with 6.5 or 8.25 in. chuck, Lynx 220 OD Turning Center is powered by 20 hp motor and features 30° slant bed with single-piece, strategically ribbed design and fine-grain Meehanite composition that dampens vibration and helps dissipate heat. Spindle accelerates to 6,000 rpm in 2.3 sec, and rapid traverses for X and Z axes are 1,181 and 1,417, respectively. Heavy-duty, 12-station turret is non-stop and bi-directional with 0.15 sec station index time.

Lynx 220 with More Speed, More Power, Lower Cost



West Caldwell, NJ - The new Lynx 220 packs speed and power in an economical O.D. turning center.

Three models are available: the 220A with a 6.5" chuck, the 220C with an 8.25" chuck and a 220LC with an 8.25" chuck and elongated bed. All are powered by a 20 Hp motor that provides the muscle to power through heavy cuts in tough metals.

A 30° slant bed maintains a minimal and constant distance from tool tip to guideway, and assures maximum rigidity and eliminates of deformation under heavy loads. This design also allows excellent chip flow and operator access for loading and unloading material, replacing chucks and tools, and repositioning the optional tailstock. The one-piece bed is strategically ribbed. Its fine-grain Meehanite composition dampens vibration and helps dissipate heat.

The spindle accelerates to its peak 6,000 rpm (Lynx 220A) in a quick 2.3 seconds. The large contact surface of the cylindrical roller bearings provides high rigidity for heavy loads and mirror finishes. All bearings are permanently lubricated, precision class P4.

The 12 station, heavy-duty turret is non-stop and bi-directional, with a quick 0.15 sec. station index time. Its heavy-duty design, with a large 8.27" diameter curvic coupling, provides high rigidity, long boring bar overhang ratios, and extended tool life. Rapid traverses are 1,181 ipm on the X axis, and 1,417 ipm on the Z. An integral tool setter minimizes the need for manual skim cuts. Its four-position touch sensor allows tool setting in any direction. Offsets are entered automatically in the controller, eliminating errors that can arise from manual data entry.

Automatic forced lubrication is provided to all guideways, ball screws and the tailstock quill. Non-clogging piston distributors minimize way lube consumption. The ½ gallon lubricant reservoir lasts up to 100 hours. Sensors activate a low-level alarm, and monitor pressure to detect open or broken lube lines.

Coolant is delivered through the turret from a 30 gallon tank by a 1.2 Hp multistage centrifugal pump. The 65 psi of pressure flushes chips from drilled holes, often eliminating the need for time-consuming peck and drill cycles. The coolant tank and chip pan are separate from the machine bed, preventing heat transfer to the machine casting. A waylube separation system removes tramp oils from the coolant reservoir, and deposits it in a separate external tank.

Lynx 220 machines can be seen at Daewoo-Doosan Infracore's IMTS exhibit, booth A-8131.
