Page 7: Package Contents
Package Contents This tool is shipped complete with everything you need to knurl you parts except the knurls themselves, which are application specific. In the event you need a spare, each part (size permitting) is permanently identified with laser-marked part # for easy identification, and replacement. All part identification in this manual will refer to the BOM Balloon # on the Assembly Drawing contained in this manual, and be noted as in parentheses after the part name, i.e.: Center Plate (#3). -
Page 8: Assembling The Tool
Assembling the Tool Your tool will come pre-assembled from the factory. In the event you need to disassemble your tool, please refer to the supplied assembly drawing for an exploded view and proper part assembly order. Please note, should you need to disassemble the gear train for the 3 eccentric roll pins, proper orientation at re-assembly is critical to ensure the rolls are concentric to the tool shank. -
Page 9: Periodic Maintenance
Periodic Maintenance CJWinter recommends an annual teardown and inspection of this tool. We recommend the periodic lubrication of all moving parts with oil, and replacement of the Thrust Bearings (#10) and Thrust Washers (#11 & #22) in the tool. The frequency of lubrication and replacement depends greatly on the severity of service the tool sees, the type of knurl being rolled, and the adherence to proper setting and operation procedures. - Page 10 4. Unlock the Adjusting Sleeve (#14) by removing the #8-32 SHCS (#21) and the Spline Brake (#19) at the rear of the Shank (#6). 5. Add backlash to the gear train by unthreading the Adjusting Sleeve (#14) until the top of master pinion is protrudes roughly 3/16"...

Page 11: Pre-Setting The Knurl Diameter
Pre-Setting the Knurl Diameter New knurl rolls may vary in diameter somewhat from batch to batch, and from new to used. When installing new rolls, the easiest way to pre-set the knurl size is to use a previously knurled part, inserted between the 3 knurl rollers, and pinch down on that part using the head size adjustment. -
Page 12: Shifting The Size Adjustment Range
Shifting the Size Adjustment Range The 192 series head is designed with an ample adjustment range, while maintaining the ability to make small, precise changes. If you run out of adjustment when setting your part size, the range can be shifted upwards or downwards to accommodate your particular part and roll diameter combination. - Page 13 7. Place additional pins in the two remaining gear timing holes. Tips and Tricks: Using a small dab of thick grease in the pin hole, or three small magnets, will help hold the pin in place while handling the head. 8.

Page 14: Work Piece (Blank) Preparation
Work Piece (Blank) Preparation Prior to knurling, the work piece needs to be prepared. Typically, the blank needs to be turned to a diameter approximately halfway between the major OD and Minor OD of the finished knurled part. To start, you may want to bias this diameter about .003"/inch smaller, so that the dies do not overfill. -
Page 15: The Knurling Procedure
The Knurling Procedure The tool motion should be programmed much like a drill cycle. The recommended SFM is between 50 and 200, with tougher and work-hardening materials trending towards the low end, and easily machinable materials trending towards the high. Axial feed rates of .010"/rev and .020"/rev are usually adequate to produce a quality knurl. -
