Slot Milling semi-automatic milling machine can be used for a square piece (such as a heat sink) and other parts of the fixture for pneumatic (hydraulic) vise. For less precision round, square or other shape rules and clamping reliable and convenient car parts can also be milling steps, flat-bit or broken trenches, also be used to rotary indexing slotted fixture for pneumatic or hydraulic fixture Block, non-circular, non-standard chuck can be equipped to do so. The models for the semi-automatic machine, the operator manually discharge and reclaimers, pieces to be machined into the fixture after the operator depresses a foot switch or press the manual switch, complete clamping, processing and returns to the initial position after the loose opening fixture, cyclic operation. The model's price is relatively low, the disadvantage is the risk of a certain operator, while labor intensity is relatively large
