9. Machine use and maintenance:
9.1
Before running the machine, carefully read the Operation Manual first, fully understand
the structure of the machine and its performance and needs to familiar with locations for
all levers and buttons.
9.2
Lubrication of the machine is very important. Daily lubrication work as per the requirements
of the operation manual is necessary. Otherwise transmission parts and bearings will be
damaged.
9.3
Max. spindle torque of this machine is 105
N.M. Max. feed resisting force in the driving
system is 7000 N. Over permitted cutting feed range is not allowed. High spindle speed
with big cutting feed is not good to the machine.
9.4
As standard drill with118 degree angle features big cutting force but quick wear-out,
so diameter and roughness of holes is not so ideal after drilling, therefore, regrinding its
edges particularly for the big diameter drills is necessary. It is better to use two different
angles for the machining of cast iron material (Second angle could be 70°).
9.5
Spot facer with three edges is proffered for the spot facing machining, using a normal
drill for spot facing job will cause vibration. However, it will have a better result for
the spot facing machining if reducing the rear angle of the normal drill with two
different angles and going down the cutting speed and feed rate.
9.6
Temperature of motor will be increased so quickly when tapping due to frequently motor
direction be changed. Therefore, rapid and continuous tapping shall be avoided. Max. eight
times per minutes of tapping is recommended. The machine shall be stopped for cooling if the
motor is too hot.
9.7
A proper cutting force is required when milling. As this is not a milling machine although
it has a milling function. Too big milling force will cause worktable moving round the
column, therefore, clamping the worktable strongly is required when milling and a
reasonable cutting feed rate for milling job is necessary.
9.8
Please turn off the coolant valve when mounting and dismounting tools, clamping or
adjusting work piece or measuring work piece, as coolant is not necessary during this
period. Stop coolant pump if these job takes more than ten minutes.
9.9
As gears are to be used for spindle and feed system, so it is not allowed to change
spindle speed or change cutting feed rate when machine running, otherwise it will
damage gears, shafts or relevant parts.
