Republic Lagun Machine Tool FTV-2F Vertical Knee Mill

Outstanding Features:

• The head is equipped with a “high velocity cooling system”. The generated “air flow” keeps the head at a constant temperature. The fully enclosed head will keep dust from the shop environment out, keeping critical parts and components such as: pulleys, belts, and bearings, etc., clean and dust free. (See detail A)
• The new head has two speed ranges, 5 HP constant drive, and infinite variable speeds. (see D) The dynamically balanced head (see B) reaches full horse power over all the speed ranges, (Low 55 to 490 – High 490 to 4,250 RPM) (See E) without the typical losses of EVS systems. This head is capable of reaching 358 ft-lb of torque (See –Graphic HP vs. RPMS) at a mere 55 RPM.
• The quill 3 3/8” (85 mm) is hard chromed with a precision ground rack.Special high performance transmission belt are used. The heart of our mechanical infinite variable speed milling head uses the same hi-technology found in the continuously variable transmission of the latest Hybrid automobiles.
• Spindle taper is R-8 (optional # 40 NST, #30 NST with four hi-precision, class 7 bearings.
• The head assembly can be tilted front-to-back and swiveled right-to-left.  Angular settings employ worm and gear.
• Ram/head assembly can be easily rotated a full 360° degrees. (See detail
• Massive ram features 19″ (483 mm) of bearing length and 22 3/16″ (563 mm) of travel.
• The ram design allows use of the optional slotting attachment.  The slots are mounted opposite the standard head (with optional kit 149-1140K).
• All lead screws are thread rolled and precision ground.
• A unique double nut assembly provides backlash adjustment of longitudinal and cross feed screws.  Adjustment of this device eliminates backlash due to wear.
• Table & saddle locks are conveniently located in front of the machine. Handles are spring loaded to allow repositioning once locked. This advanced design clamps the table to the saddle, but does not push on a gib. As a result, the table will hold its position more accurately.
