Can we make profile using Rotary tables?
CNC Rotary tables are designed to have continuous interpolation with machine axes. But it is possible only if the controller of the machine has the capability of handling regular 4th axis.
What is the indexing accuracy?
Indexing accuracy of std tables above Dia 150 is +/-15”.But higher accuracy of +/- 5” is possible with additional high resolution encoder mounted on Rotary table axis.
When do we need tail stock support?
If the component length is more than 150mm then it is advised to have the tail stock support.
What is the maximum cutting force we can apply on the table?
Maximum cutting forces allowed on the tables differs based on the size of the table. If application calls for the continuous interpolation then the max torque can applied on the table should be with in the worm gear torque capacity of the Rotary table. In case of the positioning the torque can be applied on the table while machining to be with in the clamping torque capacity of the table
What is the speed of the Rotary table?
Max speed of the table depends on the speed of the motor and gear ratio of the table. Max speed of the Motor for the Table size upto dia 250 can be 3000 RPM. For the tables Dia 320 and above motor RPM can be max 2000 RPM.
Can we mount table vertical / horizontal direction?
UCAM Rotary tables upto Dia 630 are available with Vertical / Horizontal option.
How do we check the indexing accuracy?
Indexing accuracy can be checked with auto collimator at site. At the factory it is checked with special computerized equipment for the same.
What is the material of worm and worm wheel?
For Rotary tables up to Dia 630 the worm wheel is made of aluminum bronze and for tables beyond Dia 800 it is Phosphor bronze. Worm shaft is made of case hardened steel.
Specification of oil?
Oil grade 220 at 40 degree Celsius and flash point 230 degree Celsius.
What is the frequency of oil change?
First oil change after 60 days. For continuous operation change every 3 months, if table is use intermittently oil to be changed in 6 month. If the is not used for 6 month, oil to be changed before it put in use.
How to adjust the backlash?
Backlash adjustment procedure is shown in section 6.4 of this manual.
Which type clamp (Hydraulic or Pneumatic) is recommended?
Type of clamp is depending on the torque requirement to withstand the machining forces. If the torque generated by the machining forces is higher than the capacity of pneumatic clamping torque capacity of the table then hydraulic clamping is recommended.
What is the minimum indexing angle possible on Rotary table?
For CNC Rotary table minimum indexing angle is 0.001 degree.
