Eccentric Fine Boring Tool
include/img/Eccentric Fine Boring Tools/Introduction/Big 1.jpg
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

include/img/Eccentric Fine Boring Tools/OD Turning Tool/Big 2.jpg
Notes
  •   Minimum Diameter ØD = Ø8.0mm
  •   Maximum Diameter ØD = Ø22.0mm
  •   Maximum L/D Ratio = 2.5
  •   Maximum Length L = 50mm
  •   Shank Diameter Ød = 25mm

  •   Shank Diameter "Ød" for all the eccentric tools is 25mm, Collar Diameter is 32mm & Shank Length is 56mm.
  •   Lead time of 2-3 weeks.
Operating Instructions
  •   The tool is initially set on zero mark on the scale. (pic 1)
include/img/Eccentric Fine Boring Tools/Operating Instructions/Big 1.jpg
  •   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
include/img/Eccentric Fine Boring Tools/Operating Instructions/Big 2.jpg
  •   In case you wish to adjust the diameter, loosen the Locking Screw of M8 with the provided Allen key of 4mm. (pic 2)
include/img/Eccentric Fine Boring Tools/Operating Instructions/Big 3.jpg
  •   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.
