The invention provides a cutting machine which comprises a bottom plate and a tool which is arranged on the bottom plate and is used for the cutting machine. The tool comprises a tool body. The depressed part for fixing a PCBA product to be cut is formed on the tool body. The PCBA product to be cut comprises multiple same PCBAs. The depressed part comprises multiple same PCBA fixed grooves, and the PCBAs are corresponding installed in the PCBA fixed grooves one to one. The connection part of any two adjacent PCBA fixed grooves is provided with a cutting through hole. A bottom plate is provided with an air draught through holes, and the cutting through hole communicates with all air draught through holes. The tool firmly fixes the PCBA product to be cut without shaking, a cutter carries out cutting conveniently, and the processing yield rate is improved. In addition, since the bottom plate is provided with the air draught through holes, the cutting through hole communicates with all air draught through holes, the bottom plate has a gather effect, the suction of cutting shards by a suction fan is increased, and the cleaning ability and processing yield rate are improved.
