摘要： A multiple heat source-type preheating device for a machining apparatus is provided. The multiple heat source-type preheating device for a machining apparatus includes a first heat source provision module and a second heat source provision module. The first heat source provision module is installed to be moved along a portion of a material to be machined along with a spindle adapted to rotate a tool at high speed, and is configured to preheat the portion of the material to be machined by providing a heat source thereto. The second heat source provision module is installed to be moved along with the first heat source provision module, and is configured to preheat the portion of the material to be machined by providing a heat source thereto while preceding or following the first heat source provision module.
