Diesel has a dipstick handle (Fig. 1), to be won on a rolling ruled out. Original in the lathe with ordinary boat pattern flower knife Lang system, parts easy to bend, sensitivity is low. To this end, designed a pair of knurling wheels, the use of existing rolling machine, rolling ruled on, the effect is very good.

For irrigation parts, due to the gradual cutting tooth A. Carve first tooth surface of the part of fine marks, then add probe shape. Therefore knurling wheel and shall have the following relationship between the parts

7rD/zi = 7rd/zz = f where D-collapse pattern wheel diameter Zl-roll wrinkle tooth Dear d - Part roll former OD 22 - Part Teeth f-pitch pattern has been

Such rolling out parts scalloped clear, no short teeth squandering phenomenon.

Known Part J = ~ lSmm,, r = 0.85mm, take # 2 - 66. By the structural conditions to D - lOOmm, have 2i = 369. Throw into confusion pattern wheel shown in Figure 2, take tooth angle of 60 '.
