When rubber products are processed with water, the heat generated by the friction between the workpiece and the tool can be avoided under small pressure during the entire processing process. In addition, due to the intervention of water, the rubber processing environment has become better. Water knife cutting rubber speed is very high, in the machine itself provided by the table accuracy, the dimensional accuracy can also meet the requirements. High processing quality, no need for secondary processing. The spare parts of the water jet have a long service life, the machine can be used for a long time, and the relative cost is low. The most important water jet cutting rubber will not produce dust and toxic gases, can provide a cleaner, safer and environmentally friendly working environment.
