Three factors to judge the quality of chuck

1: concentricity: our company produces tapping machine chuck concentricity precision is high, does not hurt the drill bit, tap. The poor concentricity of the chuck can easily break the drill bit or tap.

2: holding strength:Clamping force is the ability to prevent the tap from rotating in the chuck. Chuck I produced all the 65Mn spring steel multi processing high standard manufacturing, with holding high strength, strong durability and other advantages. Inferior chucks are made of inferior domestic steel, shoddy work, no guarantee of quality.

3: heat treatment detection: our company's chuck has been treated by heat treatment and heat treatment report, poor quality chuck is not even heat treatment process. It is also easy to cause fracture due to hardness deviation.
