I. Overview
1. Power supply
The following power supply voltage and frequency for the machine tool can be provided based on customer needs:
Frequency
Rated voltage
50Hz
~ 220V
~ 380V
~ 415V
~ 420V

60Hz
~220/440V
~ 230/460V
Lead-in wire of power supply:
L1
L2 three phase power supply sectional area 6mm2
L3
PE ground wire
2. Voltage of control circuit
Voltage of control circuit is ~ 24V or ~ 110V, signal lamp circuit ~ 6V and that of working lamp is ~ 24V.
Power line is black, AC control line red, working ground wire white and protective ground wire yellow green.
3. Motor of machine tool
A machine tool has three motors:
M1--- Spindle motor
M2--- Longitudinal rapid-travel motor
M3---Cooling motor
Note: Motors of corresponding frequency 50 Hz or 60 Hz are provided in accordance with user network power supply in the purchase contract.
4. Door-opening power outage
Lock of DZL5 electric control cabinet is adopted for the door of electric box, which is interlocked with power switch QF1 to realize the protection of power outage before door opening.
5. Grounding protection
User shall provided favorable grounding network and machine tool and electric box shall be properly grounded.
II. Electric control and operation
1. Preparations before start-up
The door of electric box is firstly opened with the key prior to the initial start-up of the machine tool to check whether all the automatic switches are connected and whether all connecting terminals and ground terminals are reliably connected. The door is closed after the checking is completed.
Properly close the door of belt housing and the chuck shield.
2. Start-up
Turn the door lock handle upwards and power switch QF1 of the machine tool is at the connection position, indicating the machine tool is energized. Power indicators HL1 and HL2 are on and the machine tool can enter normal work. Power supply phase sequence shall be checked for the first electrification of machine tool. Press the start-up button SB2 (green) on the push button station at the head of the machine tool and the main motor starts running. Operate the handle of start-up rod to the position of forward turning. If the spindle turns forward, it demonstrates a correct phase sequence, otherwise any two phase lines need to be exchanged in the power circuit.
3. Electrically controlled operation
The main motor has two forms of start-up and running. If it is started directly, press button SB2 (green) and KM1 is powered and the main motor starts running. If the main motor adopts Y-Δ start-up, press SB2 (green) and KM1, KM2 and KT are electrified. When the main motor uses Y start-up, KM is de-energized after 3s delay of KT and KM2 is energized and the main motor transfers to △ running. Thereafter, operating the handle of start-up rod can realize spindle forward turning, reverse turning and stop.

Rotate SA, the handle points to the right and the water pump is opened and it is closed when the handle points to the left. Press button SB3 (red), both main motor and cooling pump motor stop operation. Pressing and connecting switch SQ2 and holding slide carriage button SB4 or SB5 can make the rapid-travel motor turn forward or reversely and realize gap rapid travel to the left or the right.
4. Shutdown
If the machine tool is not used, the master power switch QF1 shall be disconnected for personal and equipment safety.
