Trust our factory to provide you with the best solutions for your boring needs.

Product Detail

FBH Back Boring Instructions

In order to check the feasibility of the back boring operation and to select the best possible tool combination, these values can be calculated as follows:

C > (D + d) / 2

C — Minimum entry bore diameter
D — Back bore diameter
d — Diameter of boring head

FBH Micro-Boring Head Manuals

Installation Of Insert Holder, Boring Bars And Inserts

① Clean the mounting surface of cartridge and boring head; Make sure there is no gap and misalignment between cartridge and boring head; Fasten the locking screw properly.

② Loosen the locking screw and move the BM center pin out of boring head. Put in the boring bar in a right direction and tighten the locking screw properly.

③ Use compressed air to clean the surface of inserts and insert pocket on cartridge. Ensure they are free of any dust or oil; Position the indexable insert on the insert pocket and tighten the clamping screw securely.

Structure

① DCK Connection

② Graduated Dial

③ Boring Head

④ Locking Screw

⑤ Locking Screw to the Center Pin BM

⑥ BM Center Pin

⑦ Cartridge

⑧ Clamping Screw

⑨ Grease Hole

Operation

① Loosen the clamping screw in anti-clockwise direction;

② Move the cartridge close to but smaller than the working diameter;

③ Lock the clamping screw;

④ Loosen the locking screw on graduated dial;

⑤ Adjust the dial in a clockwise direction until the desired boring diameter is reached.

⑥ Tighten the locking screw properly.

Notices Of The User

① Use boring head within suggested range;

② Rotate the graduated dial without loosening the locking screw will damage the internal moving structure.

③ Use genuine key only for unclamping, clamping and any adjustments.

④ Check the following two possible troubles when the rotation meets big resistance or refuses to move: If the locking screw is loosened. If the boring diameter exceeds the boring range of boring head.

⑤ Regularly apply grease into the grease hole to maintain adequate lubrication of moving part; The boring head shall be set on the smallest diameter when it is greased; Continue the grease injection till it appears to ooze out from the behind of the graduated dial; Occasionally adjust the boring head through its entire range when storing for a period of time to avoid the grease from hardening. No overhauling boring head without the instructions from DEREK.

Frequently Asked Questions

Q What is the formula to check the feasibility of a back boring operation with the FBH tool?

The feasibility of a back boring operation can be verified using the formula: C > (D + d) / 2, where C is the minimum entry bore diameter, D is the back bore diameter, and d is the diameter of the boring head. If the condition is satisfied, the tool combination is suitable for the operation.

Q What insert brands are compatible with FBH boring tool cartridges?

The FBH boring tool cartridges are compatible with inserts from DEREK, KYOCERA, and SUMITOMO. This ensures broad flexibility when sourcing replacement inserts for your machining operations.

Q How do I correctly install the boring bar into the FBH boring head?

To install the boring bar: first loosen the locking screw and move the BM center pin out of the boring head. Then insert the boring bar in the correct direction and tighten the locking screw properly. Ensure there is no gap or misalignment between the cartridge and the boring head before securing.

Q How do I adjust the boring diameter on the FBH micro-boring head?

To adjust the boring diameter: (1) Loosen the clamping screw counter-clockwise; (2) Move the cartridge close to but slightly smaller than the target working diameter; (3) Lock the clamping screw; (4) Loosen the locking screw on the graduated dial; (5) Rotate the dial clockwise until the desired boring diameter is reached; (6) Tighten the locking screw securely.

Q What adapter sizes are available for the DCK5-FBH50P and DCK6-FBH63P micro-finishing boring kits?

Both the DCK5-FBH50P and DCK6-FBH63P kits are available with standard adapter sizes including HSK63A, BT30, BT40, BT50, SK40, and SK50. Boring adapters for HSK50A and HSK100A are also available on request.

Q How should the FBH boring head be maintained and lubricated?

Regularly apply grease through the grease hole to keep the moving parts well lubricated. Set the boring head to its smallest diameter before greasing, and continue injecting grease until it slightly oozes out from behind the graduated dial. When storing the tool for extended periods, occasionally adjust the boring head through its full range to prevent the grease from hardening. Do not overhaul the boring head without instructions from DEREK.
