Instructions for proper use to avoid damage to the MAXIN Power chuck & collet
mechanism, never tighten the clamping nut unless there Power chuck
is a shank inside the bore. After removing the cutting tool
from the MAXIN, the clamping nut must be unscrewed FACE
one extra turn to prevent reduction of the clamping CONTACT
power and to ensure maximum gripping force. CLAMPING
NUT
Preset screw in order to adjust the projection length of the
cutting tool you can use a preset screw inside the MAXIN
internal bore part #9. This is supplied as an optional accessory.

Insertion of SC collets and shanks. The cutting tool should be
inserted into the collet before inserting it into the MAXIN chuck.
Insert the collet into the MAXIN chuck until the collet reaches
the front end of the chuck. For maximum rigidity and accuracy
insert the shank cutters to the full ground area of the collet.

Preset Screw in order to adjust the length of the cutting tool,
use a preset screw inside the collet (optional). When using
SC collet inside the MAXIN chuck, the runout accuracy
may be affected. In case of cutting tool damage or crash
during machining, the MAXIN chuck has to be inspected
for cracks and that proper runout is maintained.

Correct Wrong

1 Do not use Weldon type shanks.
2 Insert shank at least Lmin into the chuck.
3 In order to maintain a firm grip, the shank’s surface finish should have a roughness of at least N5.
