Even in the machinery industry, it has been a long time since it was rolled up for almost a decade. There are some researches on the craft. Although there are some things that are very small and very small, if we can get enlightenment from it, The work is still very helpful. Send a small craft of some doors, I hope everyone posts, common progress. Tip 1: Remove the vise jaws, and the other two M4 screw holes, the two pieces of steel plate with a thickness of 1.5mm flush with 2, rivets with aluminum countersunk thick 0.8mm thick brass plate 3 Fasten it to the jaws with M4 countersunk screws 1 to form a durable, soft jaw. So you can also protect the parts are clipped, but also has interchangeability Tip 2: small parts with suction magnet (feeders) suction and take are inconvenient to attract an iron below the magnet 1 not only can suck many small pieces and Will open the small iron plate will immediately automatically pour into the collection box not enough to impress the heart, but very practical tips 3: Pulley transmission pulley and often between the skidding on the wheel axle with ¢ 15 ~ 18mm Zoned nest drill a series of such nest Can form adsorption force to prevent slipping waste treasure boss will reward Tips 4: When the hexagonal wrench 1 stalk is short, can not focus on, the diameter can be slightly larger than the wrench tube from a slot milling the wrench into the slot can be As a long handle. Tip 5: For stepping up the workpiece is not what to say: first positioning then clamped argument, but? I think for a workpiece, the first clamping and then positioning, because the clamping will certainly test the workpiece deformation, it should first clamp and then positioning, for 6-point positioning, looking to limit its freedom.
