1. Spindle freezer must be run before spindle rotates. (use freezer special coolant oil, or 8 # machine oil).

2. The spindle must preheat at low speed before running at high speed (~ 12000r/min or above). Run for 5

minutes at low speed range (~ 3000r/min), then speed up. The maximum spindle speed for continuous

operation must be below 21000rpm.

3. The cooling temperature of spindle freezer temperature must be guaranteed between 18 ° C ~ 28 ° C,

and the spindle temperature must be guaranteed below 60 ° C. (The environment temperature for spindle

freezer normal use should be below 40 ° C)

4. The ER collet chuck mounted on the spindle taper must be clean, otherwise it will damage the spindle

taper and affect spindle precision, which will affect work‐piece processing accuracy.

(2) Tool sensor

1. Tool must be on the front center of tool sensor to avoid tool setting errors




20

2. The length of the tool over the spindle taper tool must be within 100mm, otherwise it will crack up the

tool sensor.

3. The tool sensor must be connected to auxiliary blowing tube, so that the value of tool setting will be

accurate and stable.

(3). Machine tool lubrication: the machine use 20 # machine oil for lubrication. When the pump's oil level is

too low, the system will automatically alarm for more lubrication oil; rail slider use butter for lubrication and

add each three months.

(4). Electrical cabinet electric

1) Disconnect power before checking machine electrical equipment, electrical equipment must be kept

clean, and electrical cabinet should regularly take dust suction and moistureproof, to prevent electrical

components damaged.

2) Check if freezer is normal working and spindle temperature is not too high before start the spindle. Use

hand to feel the spindle head, if it is too high, need to check if the freeze is normal working.

3) Check control system voltage, the fluctuation range should be within ± 10% to ensure the CNC system

and electrical component normal work.

VII. Machine operation precautions

1. Power supply and input voltage should be three‐phase five‐wire system 380v

2. 10 kg 20 # machine oil for screw lubricant; 13kg white mineral oil for oil cooler; 430 water tank needs

25kg white mineral oil; 650 water tank needs 65kg white mineral oil.

3. Air pressure for machine is 6kgf/cm

4. Machine rail lubrication butter add once each three‐month

5. transducer panel display PF means phase lack. Solution: Check if the input power cord loose, and

re‐connect.

6. Oil cooler panel alarms with RE means three‐phase reverse or phase lack. Solution: swap any two of the

input power cord.

7. If spindle rotate speed will be above 12000rpm, must preheat at low speed of 3000rpm for 5 minutes




21

before, then speed up at 3000rpm every five minutes till target speed. The maximum spindle speed of

continuous operation must not be higher than 21000rpm.

8. To machine with magazine tool, it is prohibit to directly mount tool to tool magazine. Must through

spindle tool setting and changing action (such as M6T1).
