Model 2000 & 2500 Boring Bar

SPR York’s Large Diameter Boring Bars are specially designed for the shipbuilding industry. Boring diameters from 400mm to 1600mm.

The Model 2000 machine uses an 8″ diameter boring bar to machine bores from 16″ to 60″ diameter.

The Model 2500 machine uses a 10″ diameter boring bar for boring from 28″ to 72″ diameter.

The boring bar comes chrome plated and has two leadscrews at 180 degrees to feed the cutter head smoothly along the full length. The bars are available in lengths of 30′. Both machines are powered by a 40 HP hydraulic power unit that features a hand held remote control for setting the feeds and speeds. If you have large bores that need machining, SPR York has the machine to do the job. For more information on purchasing or renting, request a quote below.
