Description

Accurate. Rugged construction and precision components ensure accuracy and repeatability over many years. Heavy duty compound slides and one-piece cast iron base increase rigidity and minimise vibration. The workhead incorporates precision needle roller and thrust bearings, while the main chuck spindle utilises a rotalin bearing giving less than 0.005 mm deflection. The six-jaw chuck accurately centres the drill to ensure each cutting lip is equally ground for both length and angle to develop a precision point.

Versatile. A wide range of points can be ground: Right-hand and left-hand drills with point angles between 40o and 180o, standard, centre drills, carbide drills, step and subland drills, taps and reamers. Also a number of NC self-centre points can be ground, including split, four-facet and spiral. Cutting lips can also be corrected.
