LUBRICATION&MAINTENANCE

1.Lubrication & Maintenance

It is very important to pay special attention to the lubricant oil because an incorrect selection can deteriorate the accuracy and shorten the life of precision index drives.

Viscosity of Lubricant Oil

Note 1. In the case where the speed of input shaft is not fixed, obtain the viscosity by the use of either following: Geometric average speed that is Nmax. x Nmin. or the speed of the high frequency in use.
Note 2. When the speed is just on the boundary where the viscosity should be changed, select the higher one in each range.
The roller is very important driving parts in the cam indxer, over load on the output shaft is forbidden.If there is  abnormal  noise or the output shaft can't self lock when it move to dwell angle,it means the roller is broken.Please contact with HICPU service department when you need change the roller.

2.Maintenance

The backlash in the input drive system causes vibration and noise which affects the accuracy and expected life. Chains and flexible couplings, especially, gain backlash and wear because they become loose after a relative short period of use.

An axial alignment in the shaft connections is also important. When fastening connected portions, carry out without leaving any looseness. The overload on the cam followers through the output shaft should be eliminated, sometimes leading to the follower's breakage. Therefore, we supply a safety device to free from those failures. 
Whenever abnormal noises are heard, it could mean damage to the follower, stop the operation and check for the cause.
Every 5000 hrs. of operation, a check is required. In the dwell range of the index drive, if backlash is observed, replace the follower.

3.Lubrication
Frist : at 1000 hrs. of operation after initiated.
After then: at every 3000 hrs. of operation.
Note : Even if the operation hours do not reach the
above, the replacement is required at least
