Description
Our cutter grinder is ideal for creating accurate points with ease.
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.
