Features & Benefits • Electric or hydraulic drives provide variable speed and constant cutting torque throughout the entire speed range • Self-aligning bearings secure to the boring bar with split tapered sleeves for vibration free cutting • Modular boring head provides flexibility and rapid setup • Electronic axial feed improves quality and productivity by providing rapid tool positioning and on-the-fly feed...

2250P Boring Bar Designed specifically for covering a range from 63.5 mm-609.6 mm (2.5"-24") diameter, in lengths up to 3.66 m (12'), the 2250P Boring Bar strengthens an already significant offering of Hydratight boring bar solutions. Many of the design elements of this Boring Bar have been pulled from the larger capacity, field-proven 8200 series of machines. A key area of this design transfer is the rotational drive unit. This assembly uses a 5:1 double enveloping worm gear which provides 25% more cutting torque than any other boring bar within its class. This robust assembly has hydraulic,...

Optional Accessories • Additional heads are available which provide a range from 114.3 mm–609.6 mm (4.5"–24") diameter; and are equipped with a fine radial adjustment allowing for quick and accurate setting of tool position. • An optional facing/grooving head is available which covers a range from 57.2 mm–533.4 mm (2.25"–21") diameter. The cutter head is advanced using a cam tripper which actuates the cutter over an increased surface range. • Universal bearing supports increase range of mounting options in tight spaces. • Intermediate supports are available to assure a ridged set-up.
