Choosing a special engraving knife for the Saint Ma T engraving machine mainly depends on the blade angle, tool material, processing material, and usage scenario. Choosing the right engraving knife can avoid problems such as breakage, incomplete engraving, and rough edges, and improve cutting accuracy.
Firstly, look at the blade angle, which is the core of selection. The 30 ° sharp blade has high sharpness and is suitable for fine cutting of small characters, fine patterns, heat transfer films, etc. The lines are delicate and free of burrs. The 45 ° knife is a universal model that is compatible with most instant stickers, car stickers, and ordinary engraving films, balancing sharpness and durability, and is a regular item in stores. The 60 ° blade has a thicker and more durable edge, with strong pressure resistance. It is specifically designed for cutting hard materials such as engineering reflective film and thick PVC, making it less prone to breakage.
Next, choose the material of the cutting tool. For daily processing, choose ordinary tungsten steel knives, which have high cost-effectiveness and meet daily engraving needs. For long-term large-scale processing of thick materials, it is recommended to use imported hard alloy knives, which have higher hardness, wear resistance, and durability. Their service life is more than twice that of ordinary engraving knives.
Finally, the model is matched with a universal standard T-shaped handle for the entire Saint Ma T series, without the need to modify the blade holder. Choose a 45 ° tungsten steel knife for daily use, a 30 ° knife for fine processing, and a 60 ° knife for cutting thick reflective film. Match as needed to balance cutting effect and usage cost.
