OWNER’S MANUAL
The Machine Assembly
The Transmission System
Transmission of the Spindle: The spindle motor drives the belt pulley (1), and through the Belt
(2), drives the belt pulley (3) to realize the spindle transmission.
Transmission of Drilling and Milling: The drilling and milling motor drives the motor pulley (5),
and through the belt (6), drives the belt pulley (7) to realize the spindle transmission.
Longitudinal and Transverse Transmission: The longitudinal feed transmission is carried out by
longitudinal thread (13) and nut (14); the transverse feed transmission is carried out by
transverse thread (15) and nut (16).
Transmission of the Tool Post: The tool post feed transmission is performed by tool post thread
(17) and nut (18).
Transmission of the Tailstock: The tailstock feed transmission is achieved by tailstock thread
(12) and nut (11).
The Electrical System
This machine is powered by two separate AC motors. The motion of turning motor is controlled
by a combination switch SA, and the motion of drilling and milling motor by a button switch SB
(Fig. 4).
For safety purposes, the machine should be grounded.
A 10A fuse should be fixed in front of the supply socket to maintain short circuit protection.
