MACHINE COLUMN MAKING METHOD

摘要

PURPOSE: A column of a machine tool and a production method thereof are provided to improve a damping characteristic of the column by reinforcing a long fiber reinforced polymer composite material or an SMC(sheet molding compound) to the column of the machine tool. CONSTITUTION: A long fiber reinforced polymer composite material or a composite material plate(14) produced with an SMC is reinforced to the surface of any one part of the inner or outer part of the column(12). Thereby, the high vibration generated in the column of a machine tool(10) is damped so that accuracy is improved. Herein, to produce the column, the composite material is accumulated on a reinforced part of the column. The column is covered by a vacuum bag and put in an autoclave. The composite material is hardened by giving pressure outside while keeping a vacuum state in the inside. Accordingly, the column reinforced by the composite material is produced.
