PORTABLE BORING MACHINE

摘要

A feed assembly, a boring head and an alignment device. The feed assembly may include a feed mechanism; an adjustment mechanism to adjust a feed rate of the feed mechanism; and a gage to indicate the feed rate. The boring head may include a body supportable on and for rotation with the bar; and a tool holder to support a tool to work on a workpiece and supported for radial movement on the body to adjust a radial position of the tool. An alignment device may include a clamp lockable in an axial position on the bar; an alignment member engageable with a bore of a workpiece; and an adjustment member between the locking clamp and the alignment member, the adjustment member and the alignment member include complementary threads, the adjustment member being rotatable about the axis to move the alignment member relative to the clamp along the axis.
