Knuth R60 radial drillClick image to enlargeKnuth has introduced a new "R" series radial arm drills that range from 33 mm (1.3 in.) drilling capacity with a 813 mm (32 in.) spindle to column distance all the way to a 100 mm (3.94 in.) drilling capacity size with a spindle to column distance of 3,150 mm (124 in.).

 The new series feature an infinitely variable spped spindle gearbox. With teh R-60, 38 - 2,000 rpm (2,000 rpjm provides the proper rotational speed to run a sril as small as 1/8 in.). The R-100 model is a 22-step direct gear drive drill head with 8 - 1,000 rpm. It is equipped with an individually adjustable multidisc-reversing overload clutch on the main spindle, which reduces high torque forces when the spindle is reversed thereby increasing the life on the spindle drive gears. An adjustable drilling depth stop which improves the hole-to-hole depth accuracy.

It is build with three electric motors: the main spindle motor, horizontal arm lift motor, and coolant motor (the R-80 and R-100 drills also come standard with an additional drill head positioning motor.)Gear sets have oil bath-submerged lubrication, while the rest of the machine boasts a central lubrication system. An automatic positive electromagnetic lock on the horizontal arm increases operator safety in the event the arm is not locked prior to drilling. Automatic quill feed ranges from 0.0024 - 0.126/rev.

The new series also feature, an excessive counter-weight base (the R-60 weighs in at 8,400 lbs), a precision machined cube table that comes standard, at no extra cost, on all KNUTH Radial Arm Drills, and drill head and column can be clamped/released, either together or separately, via the control switch.
