Q: How to mount and remove the drill chucks on tapered spindles?
A: To mount chucks:
Clean both tapers of all grease and grit. With the chuck jaws completely refracted into the chuck and using a thin piece of wood to protect the chuck nose, tap the chuck into place on the spindle.
To remove chucks:
If a power tool has a tapered spindle, the chuck may be removed from the spindle by inserting chuck removal wedges between the chuck back and the spindle housing.
Q: Why are SANOU drill chucks so accurate?
A: In-process gages are used to check all components at each stage of the manufacturing process. Upon assembly, each chuck is qualified with 4-6 different diameter test pins at two distinct locations on each pin.A quality control inspector repeats this process with 4-6 packaging.
Q: How about the life of SANOU drill chuck?
A: SANOU drill chuck have longer life, because SANOU drill chucks are extremely accurate, drills are subjected to uniform wear, resulting in longer life.
All SANOU drill chuck parts subject to wear are hardened and ground for long life.
Q: Why is the accuracy so important?
A: Chucks which have excessive runout cause drills to wobble, resulting in oversized holes. Suppose you are producing a part which calls out for a drilled and reamed hole. If the drill runs out, an oversized hole will be created and the reaming tolerance could be used up. An error like this often costs more than the price of an SANOU drill chuck.
