OPERATION
MOUNT/REMOVING TOOLING
Mounting straight shank tools
Straight shank tools
(Drill/Reamers/Spot facing) can be
mounted in spindle using drill
chuck, collet chuck and MT-2 shank
arbor.
Clean spindle nose (MT-2 taper
bore) / tool holder.
Select correct size tool holder and arbor.
Fix arbor and tool holder together.
(Taper fixing)
Mount arbor + tool holder
assembly into spindle by firmly
pushing arbor against spindle in
one quick action. (Ensure correct
tang orientation of arbor).
Check true running of mounted tool
holder.
Insert tool shank and firmly grip it
in chuck.
CHECK TRUE RUNNING TOOL
BEFORE USE.
Mounting taper shank tools
Tools with MT-2 taper can be
mounted directly into spindle
nose.
For tools with MT-1 taper, suitable
MT-2 to MT-1 reduction sleeve is
necessary.
Clean spindle nose (MT-2 taper
bore) / tool holder.
Select correct size tool and sleeve
(if required)
Fix sleeve & tool together. (Taper
fixing if required)
Mount tool assembly into spindle
by firmly pushing MT-2 taper
portion against spindle in one quick
action.(Ensure correct tang
orientation)
CHECK TRUE RUNNING OF TOOL
BEFOR USE.
*Switch-Off power supply & ensure spindle has
stopped
*Clean hands, Use cotton cloth for cleaning parts.
*Take necessary care during removal & risk of tool
falling!

Removal of tools/ holders from
spindle
Tools / holders mounted
into machine spindle can be
removed easily using a
taper drift / wedge.
(Supplied with machine).
STOP SPINDLE AND SWITCH
- OFF SUPPLY
Lower spindle and insert it
from small drift slot with
sleeve drift slot.
Use provided drift / wedge and
insert it from small side into
drift slots (of sleeve & spindle)
Lightly hammer / tap open end
of drift to drive it into slot, to
cause tool
/ arbor to slip-out from taper
holding.
USE GLOVES TO PROTECT
HANDS
* NEVER ATTEMPT removing tool / arbor etc. by moving
spindle / sleeve against head stock, while drift / wedge is in
slot. This will damage sleeve / drift / spindle.
* Take care! Tool / Arbor/ Chuck etc. may slip –out during
mounting / removal and may cause injury.
* Take care! While lowering head stock / work table, safety
ring must be positioned + locked in desired position, before
loosening head- stock / work table on column.
* Take care! When changing tools, installing pulley belt, Changing
speeds.
