Eccentric Fine Boring Tools
Eccentric Fine Boring Tool
Facts & Advantages
  •   Used for finish boring application from diameter 5mm up to 25mm (any intermediary size on demand).
  •   Available with adjustment options of ±0.1mm (LC 10 microns) & ±0.3mm (LC 30 microns).
  •   User friendly & quick adjustment ensures minimum loss time.
  •   Guaranteed repeatability by using recommended torque for locking.
  •   Most economic solution for finish boring with precise adjustment in microns.
  •   Tailor made tools with similar concept also available for the application of Back Boring and OD Turning

Operating Instructions
  •   The tool is initially set on zero mark on the scale. (pic 1)
  •   After clamping the tool in the hydro grip or side-lock adaptor or ER collet chuck adaptor, measure the exact diameter on the pre-setter or by using a precise dial indicator
  •   In case you wish to adjust the diameter, loosen the Locking Screw of M8 with the provided Allen key of 4mm. (pic 2)
  •   Use the same allen key to adjust the diameter by using the scale mentioned on the body of the tool. (pic 3)
  •   The smallest division is the least count of the tool, adjust accordingly and then recheck if the required size is achived. (pic 1)
  •  If the required diameter is achieved, tighten the locking screw with a torque wrench using a torque of 8 Nm (Recommended) for precise repeatability and to ensure sufficient torque for locking (pic 2)
  •   The tool is now ready to use.
Precautionary Measures
  •   Due to constraints in the assembly tolerances, it is recommended that tools, if damaged, are to be returned to Renuka Tools for assessment/repair in a controlled environment. Commercials for repair can only be determined after detailed assessment of the damaged tool.
  •   Please change the locking screws and insert screws ahead in time to avoid accidents.
  •   Kindly change the mounting screws and insert screws ahead in time to avoid accidents.
  •   In case of any observed decrease in accuracy over the time of usage, kindly request Renuka Tools for servicing the tool.
