Notes
  •   Diameter of Adaptor ID for all of the above is 40mm.
  •   Working Length for all of the above is 50mm.
  •   Special Adaptor Bolt item code RTABM840 will be provided along with the Adaptors and if required additionally, can be ordered separately as well.
  •   Customized adaptors for any other spindle taper can also be provided but will be made to order with lead time of 3-6 weeks.
  •   In the above table, denotes ready in stock and denotes lead time of 2-3 weeks.
Operating Instructions
  •   The boring head is initially set on minimum mark on the scale.
include/img/Boring Kit/Operating Instructions/Big 1.jpg
  •   Follow below instructions to assemble the boring kit: a) Clamp the required boring bar on to the boring head with the help of the clamping screws provided with the boring head. b) Clamp the adaptor on to the boring head with the special adaptor bolts provided with the adaptor.
include/img/Boring Kit/Operating Instructions/Big 2.jpg
  •   Post assembly, measure the exact diameter on the pre- setter or by using a precise dial indicator.
include/img/Boring Kit/Operating Instructions/Big 3.jpg
  •   In case you wish to adjust the diameter, loosen the Locking Screw of M10 with the provided Allen key of 8mm. (pic 1)
include/img/Boring Kit/Operating Instructions/Big 4.jpg
  •   Use the fine adjustment dial to set the required diameter. (pic 2)
  •   The smallest division is 10 microns and one rotation is 0.75mm radially, adjust accordingly and then recheck if the required size is achieved. (pic 3)
  •   If the required diameter is achieved, tighten the locking screw with a torque wrench (recommended) for precise repeatability and to ensure sufficient torque for locking. (pic 1)
  •   The tool is now ready to use.
  •  It is recommended to dismantle the boring kit and set to minimum after use, if to be stored for long period without use. (pic 4)
  •  To avoid damage due to rusting, ensure periodic lubrication.
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.
  •   In case of any observed decrease in accuracy over the time of usage, please request Renuka Tools for servicing the tool.
  •   Ensure that the locking bolt is loosened before using fine adjustment to avoid internal damage to adjustment mechanism.
