PORTABLE TURNING MACHINE
A portable turning machine includes a support placed on and fixed to a floor, a ring base supported by the support, a turning ring that is turnably supported by the ring base and arranged on an outer circumference side of a collector ring, a motor for turning ring that turns the turning ring, and a tool that is attached to the turning ring and is used for performing corrective machining of the collector ring. The ring base has a structure that is dividable into a lower dividable type ring base and an upper dividable type ring base. The turning ring has a structure that is dividable into a lower dividable type turning ring and an upper dividable type turning ring.
1 . A portable turning machine comprising:
a support placed on and fixed to a floor;
a ring base supported by the support;
a turning ring that is turnably supported by the ring base and arranged on an outer circumference side of a cylindrical or columnar to-be-machined object;
a motor for turning ring that turns the turning ring; and
a tool that is attached to the turning ring and used for performing corrective machining of the to-be-machined object, wherein
the ring base and the turning ring each have a structure that is dividable into a lower portion and an upper portion.
2 . The portable turning machine according to claim 1 , wherein
the support has
a first shifting mechanism that shifts the ring base in a first horizontal direction orthogonal to a turning center line of the turning ring, and
a second shifting mechanism that shifts the ring base in a second horizontal direction parallel to the turning center line of the turning ring.
3 . The portable turning machine according to claim 2 , wherein the ring base and the turning ring each have a structure that is dividable into a lower portion and an upper portion along a dividing line that is inclined to a horizontal direction.
