YDTech® manufacturer of CNC drive (driving) pins on CNC face driver for CNC machining(turning, drive systems)! supplier of hardened drive grip pins on workholding for CNC laths in china.

we only produce drive pins, needle roller pins,precision hardened parts,etc. custom your drawings or samples. not face driver.

face drivers allow you to machine the entire length of the workpiece at high speeds. the other option is to chuck or use a drive dog to drive the part, which doesnt allow you to machine the part in one process. since face driving is performed in one single clamping during machining, a higher accuracy is achieved.

minimum stock size should be .030 larger than driving diameter. maximum stock size should be no more that 2x driving diameter. to determine rotation look directly at the chuck or spindle: clockwise:use lefthand pins. counter clockwise:use right-hand pins

to replace drive pins: loosen cap retaining screws and remove nose cap from body. withdraw drive pin retainers and remove drive pins. when replacing drive pins, be certain the chisel point is oriented correctly for proper drive ratio.

the center pin located on the side of the tailstock pushes the work piece against the movable center pin of the face driver. the center pin will draw back until the surface of the work piece bears against the drive disk.

finishing hardened workpieces using face drivers is gaining greater acceptance with the advanced capabilities of face drivers, machine tools and cutting tools. to ensure proper workholding, a suitable driving element, one which can handle high-tolerance demands and still be cost effective to make hard turning possible, is needed. one option is a system of micro-serrated and hard-coated drive pins mounted around the face driver.

mechanical face drivers deserve a closer look as an alternative to other types of traditional chucking methods. in many cases, using mechanical face drivers for turning applications provides increased flexibility and lower cycle times. the major benefit of a face driver is that it allows the workpiece to be completely turned from one end to the other in one operation.

face drivers, used in conjunction with live or dead centers, allow the complete turning or grinding of the entire outside diameter of a workpiece in single operation. even facing and chamfering of the ends of the part can be accomplished with the careful selection of the correct face driver and offset drive pins.

the initial tailstock force is reduced during the final pin penetration. as soon as the cut starts, the operator should retighten the tailstock to maintain the required force. on lathes equipped with a power-operated tailstock, the required tailstock force is automatically maintained.

the drive pins(cutting) operation must be toward the face driver. note the uniformity of each indentation. this uniformity indicates that every drive pin has penetrated the face to the same depth, assuring equalized drive by each pin during machining operations. pin penetration in the initial clamping stage ranges from 0.003 to 0.005, and ranges from 0.010 to 0.020 in the final clamping phase. we only produce drive pins, needle roller pins,custom your drawings not face drivers.
