BUMP HOLDERS FORM ROLL KNURLING TOOL HOLDERS *ORBH-BPS is left hand style, mirror of above view. Other holders are normally supplied as right hand style, as shown. Holders are available in opposite hand by request. Bump type knurl holders are best suited to shorter work or longer work if knurling can be done close to the chuck or tailstock. When a long, raised diamond pattern is required, a different type of holder, using one right hand and one left hand knurl is recommended (following pages). A carbide pin and hex wrench are included. Knurl is not included. Setup procedure: Mount the holder perpendicular to the spindle, in the turret or cross-slide. Move the holder toward the spindle until the knurl just contacts the work. Adjust a small amount deeper and make a test roll. If the knurl pattern is too shallow adjust it again. These holders are designed to fit medium to large size CNC or manual machines, and to roll more difficult jobs. They are supplied as right-hand style, but may be reassembled as left hand style. Use RH and LH knurls to produce a diamond pattern and traverse to produce long knurl patterns (beveled knurls are recommended when traversing). Carbide pins and hex wrench are included. Knurls are not included. Setup procedure: Adjust the two nuts on the eyebolt until the knurls just contact the work. Adjust slightly smaller and make a test roll. If the knurl pattern is too shallow, adjust again. Both nuts should be tight when adjustment is finished. Face knurling holders are suitable for knurling narrow bands (especially on tubing). They may be shifted off center to vary the diameter of knurl band that is produced. At smaller diameters, or where appearance is critical, face holders may not be suitable because the knurl pitch must change as the diameter changes (knurling a wide face in narrow, separate bands will allow the tracking to correct itself). Conical holders should be used for more difficult applications. A carbide pin and hex wrench are included. Knurl is not included. 3 DIE HOLDERS TURRET MOUNTED HOLDERS Right hand and left hand knurls can be used together to produce a diamond pattern. They also may be traversed to produce a long knurl pattern (beveled knurls are recommended when traversing). Straddle knurling produces much less side pressure than bump knurling. This reduces pressure on your machine and allows knurling longer parts or smaller diameter parts. These holders are supplied as right-hand style, but may be reassembled as left-hand style. Carbide pins and hex wrench are included. Knurls are not included. Setup procedure: Adjust the two screws on the top of the holder until the knurls just contact the work, then retract. Adjust the screw closest to the knurl a small amount tighter. Make a test roll. If the knurl pattern is too shallow, adjust again. Self-centering holders are suitable for knurling diamond patterns with 1 right hand and 1 left hand knurl. The pivoting head floats to align with the part to be rolled.This popular type of tool is simple to use and is adequate for many applications. A carbide pin and hex wrench are included. Knurls are not included. This type of tool is often used to repair parts with holes that are slightly oversize. Sometimes knurling new parts before press fitting makes assembly easier, and allows more machining tolerance. In addition, the finished assembly should be capable of transmitting more torque. A straight knurl with bevels is normally used. A carbide pin and hex wrench are included. Knurl is not included. Setup procedure: Mount the holder parallel to the machine spindle. Carefully guide the knurl inside the hole and just contact the work. Adjust a small amount off center, toward the work and make a test roll. If the knurl pattern is too shallow, adjust again.
