11 9 Installing and adjusting 9. Installing:when the turret is installing at first the assemblies must be coating oil and the driving system must be lubrication.make sure the fixing surface is clean and squared to ensure a proper tool alignment.align the front surface of the disc in order to have it perpendicular to the spindle axis. 9.2 Adjusting The electeric cnnection must be carried out according to the 5T diagram,the connection cable must be probided with fittings and gasket in order to penetration of water into the turret.when the turret can not indexing at this first must be cutoff the power switch and detected phase of the motor and then restarted,when the turret indexing the turret must be agile and no abnormal sound. Use and maintenance. The back cap do not removed and every assembly do not changed..2indexing frequency<6 ycle min..3the CCW clamping time is equal to.6-.8s..4 Maintenance.4. Every day must be lubricating the mechanical part

12 of the turret,and after tree month must be changed lubricate and coating the oil for the tool disc. Fault finding list correction Fault findiing correction Motor can t statrt or upper body can t rotation. Upper body rotatting continually and can t stop After having corrctly perfomed the indexing cycle the disk still unloked The disc goes on rotating without stopping or over The face of the workpice presant some ripple )phase inversion votage ia too low )signalling disc bad contact 2)signalling disc fault 3)hall unit is broken or short 4)pole of magnet steel is inversion. 5.the position of the manet steel and hall unit is relative departure. 6.the hall unit or magnet is bad )the time of the CCW so short. 2)bad contact.3with the locking signal cutoff the CCWrotating signal. )the position of the magnet and hall unit no good.delay between the CW and CCW is so long Cut off the power at once adjust the phade and voltage of the motor then start agan. Unload cover,checking signalling disc and supply,adjust the position of the magnet and hall unit or replace hall unit Adjusting the time of CCW,checking wire if the turret.can t with the locking signal for the motor in CCW Adjust the position of the magnet and hall unit and delay time between the Cw and the CCW. Adjusted clamping )the turret is not clamping. time(mst be according to 2)fault of the mechanical system the instruction of the turret) Note :when adjusting the relative position of the hall unit and magnet the carrier must be locked and the position of hall unit must be /3ahead magnet steel. 2 Disassembly and Installation(Assembly) 2.

14 2.2 Note: 2.2. when you dismantling the turret must be marked relatively position of the assembly and do not attained sealed ring of the turret when you reassembling the turret it is must be makesure the fixing surface is clean and haven t dust or other material when you adjusted coder at first must be lock the turret at any position and set an appproximate positioning by rotating the unit to get the corresponding position code or the signal passes from to and mark this new position and tighten the screws of the fixing pieces. 3 Discard 3.. Disassemble the tool carrier into parts, clean the greasy dirt of all parts. 3.2 Remove all the seals in the tool carrier. 3.3 Sorting each part. 3.4 Dispose or reuse in accordance with the local resources recycling or disposal regulation.
