CNC210 Operating Manual
X axis, Z axis feed motion is by two step through the coupling (synchronous belt and
synchronous belt wheel) connected with the ball screw nut pair then by the ball screw nut transfer
to the carriage or in a small trailer to achieve. Ball screw nut pair has been pre- tight, can achieve
high precision gap less transmission
5.2.4 photoelectric encoder drive system
The main spindle photoelectric encoder is driven by the synchronous belt wheel on the main
spindle to drive the synchronous belt wheel on the encoder seat.
5.2.5 tool post
The machine can be used in two rows tool carriers,and can be equipped with four electric
station.The electric post’s transposition locking directly from the electric post built-in motor drive,
direct control by the NC system.
5.2.6 tail seat
Tail stock is manual tail stock. Tail stock manually according to the eccentric principle
locking on the bed, with the hand cranking wheel moving screw the tail stock sleeve forward
backward; loosen eccentric locking mechanism, manual movement of the tail stock body sliding
back and forth.
When the work is carried out by using the tail seat, the locking sleeve is needed to be locked.
5.2.7 Lubricating System
5.2.7.1 the bearing of the spindle
The machine spindle bearings using 3 lithium grease lubrication, filling the number of 1/3 to
2/3, the machine tool factory has filled with grease.The bearings should be clean up every time
and add the same type of grease,when overhaul the machine.
5.2.7.2 The lubricating of the feeding system.
Feed system of the sliding interface using lubricating oil, consisting of a manual centralized
lubrication system and pipeline.And Z axis screw support bearing adopts 3 lithium grease
lubrication, we have add in the assembly. We can replacement according to the situation ,but the
first thing you should do is cleaning.The concentration oil lubricating tank should keep sufficient
oil , liquid level shall not be lower than the half of the calibration standard oil. Each shift before
starting machine, the first thing is to pull up hand pull the pump handle more than 3 times and
wait for after a few minutes before operating the machine. In order to ensure the lubrication points
to obtain the full lubrication.
