The suction holes have cross grooves to expand the acting area. Thus, few thread valves are used to improve work efficiency.
The chuck work face is made of iron to allow self grinding to recover parallelism.
Since the chuck work face is made of iron, magnetic devices can be utilized as workpiece stoppers.
A special suction hole layout adapter can be installed according to workpieces and work procedures.
These chucks can be mounted on magnetic chucks.
