Tip 1: for stepping up the workpiece has the first positioning and then clamping, but for a workpiece, the first clamping and then positioning, because the clamping will certainly try the workpiece deformation, so, should be the first clamping and then positioning, for the 6-point localization, looking to limit its degree of freedom.

Tip 2: magnet to absorb small parts (fee pieces) suck and take are not convenient, can be sucked in the magnet 1 below an iron plate 2, not only can suck a lot of small pieces, and will pull the iron plate, small pieces will be immediately and automatically dumped into the collection box, not enough to impress the heart, but very practical.

Tip 3: pulley drive, the pulley often slip between the pulley and the axle, in the axle with ¢ 15 ~ 18mm scratch nest drill cut a series of nests, so that you can form the adsorption force to prevent slippage, turn waste into treasure, the boss will reward.

Tip 4: When the hexagonal wrench 1 handle short, can not force, can be slightly larger than the inner diameter of the wrench tube from a section of the milling slot will be inserted into the slot wrench, can be used as a long handle.

Tip 5: remove the jaws of the vise, another two M4 threaded holes, two pieces of steel plate flush with the jaws 1.5mm thick, with aluminum countersunk head rivets riveted to the hard brass plate 0.8mm thick 3 will be fastened to the jaws with M4 countersunk head screws 1, the formation of the soft jaws used. This also protects the hardware parts from being clamped and has interchangeability.
