PROBLEM TO BE SOLVED: To provide a metal working machine causing no great deal of energy consumption by performing machining with coolant poured, being capable of securing a high level of uniform machining accuracy, reducing running cost of a tool by resolving clogging of the filter and including a microfinishing machine. SOLUTION: In the metal working machine including the microfinishing machine using the microfinishing film 6 which is the tool for finishing an outer or inner face of a steel pipe or a tubular body for use as a component of a vehicle with high accuracy, a machining point or a machining zone where a part to be machined 15 of a workpiece 1 comes in contact with the tool, that is, a machining region where the part to be machined of the workpiece comes in contact with the tool 6 is disposed within a coolant tank 5. |
