BAYOT-REAM USER GUIDE ATTENTION: Cutting tools can break during use. To avoid injury always use safety precautions such as gloves, shields and eye protection. Assembly Instructions (BN5-BN9) First Assembly 1 Clean the toolholder pocket (Fig. 1) 1 Clean the reamer head clamping cone Insert the clamping screw into the holder and rotate it 2-3 turns in a clockwise direction (Fig. 2) Clamp the reaming head on the screw; note, BN8 and BN9 can be assembled only in a specific position relative to the screw (rotate the head until locating the correct position) (Fig. 3) Manually rotate the reaming head until it sits firmly in the pocket Tighten with the special key (Fig. 4) Make sure there is no face gap between the toolholder and the reaming head (Fig. 5) Indexing Release the reaming head with the key, turning in a counterclockwise direction until it rotates freely Rotate another one turn by hand Remove the reamer head from the tool; the clamping screw should remain inside Clean the pocket of the toolholder (Fig. 1) Clean the cone on the new reamer head Clamp the reaming head on the screw; note, BN8 and BN9 can be assembled only in a specific position relative to the screw (rotate the head until locating the correct position) (Fig. 3) Manually rotate the reaming head. In the beginning it should rotate without the screw and then (after 1/6 of a turn) it should engage with the screw. Rotate until it sits firmly in the pocket. If the screw rotates together with the reaming head from the beginning, remove the reaming head and open the screw another one turn. Tighten with the special key (Fig. 4) Make sure that there is no face gap between the toolholder and the reaming head (Fig. 5) 720 cn z CD E z co CV CM BN8 17-20 N m BN7 13-15 N m BN6 8-10 N m BN5 7-8 Nxm Lead Code / Parameter P° a mm g° b mm A 45° 0.5 B 25° 1.07 C 45° 0.5 8° 0.75 D 30° 0.5 4° 1.85 E 45° 0.2 F 90° - G 75° 0.15 X Specially Tailored (undesignated) r a i / When choosing a reamer, it is important to select a lead geometry that covers the reaming allowance. Reaming Allowance Reaming allowance is the stock material which should be removed by reaming. It is recommended to leave different reaming allowances depending on the workpiece material and the pre-hole quality. Pre-hole should be smooth and straight, without deep scratches on it. A - Reaming allowance A = 0DR - 0DP Complementary Grades (on request): IC30N cermet tipped, recommended for reaming the following materials: non-alloyed (mild) steel, low alloyed steel (<5% of alloying elements), free cutting steel, tempered steel (tensile strength <1100 N/ mm2) and nodular iron (GGG40, GGG60, etc.) ID5 (PCD) recommended for high speed reaming of aluminum (special cases). RN01 (DLC coating) recommended for reaming the following materials: aluminum alloys (cast, wrought, etc.), brass, bronze and other nonferrous materials. 0 Rear )R ning 0 Pre- Dp hole Hole 0 mm Steel and Cast Iron Aluminum and Brass < 9.5 9.5 - 11.5 11.5 - 13.5 13.5 - 16 16 - 32 >32 0.07-0.10 0.07-0.10 0.07-0.15 0.10-0.15 0.10-0.20 0.15-0.25 0.10-0.30 0.20-0.30 0.10-0.30 0.20-0.40 mm/0 0.20-0.40 0.20-0.50 mm/0 Member IMC Group kSSII t b a REAMERS
