There are roughly three types of lathe tool holder structures. 1 cylindrical pin positioning tool holder structure. 2 taper pin positioning tool holder structure. 3-end sprocket positioning tool holder structure. Which of the three types of tool holder structures is most suitable? First, the cylindrical pin positioning tool holder structure cylindrical pin positioning tool holder structure (Fig. 1) is an old structure, and there are still manufacturers at home and abroad. Features: 1 On the square knife holder 4, 4 inclined grooves are used on the bottom surface, the positioning pin 1 is inserted into a groove for positioning, and the hand pushing square knife holder 4 is indexed, and the structure is simple and low in cost. 2 determine the tool turn
Stop Valves are closed by screwing a rubber gasket down onto a seat in the middle of the valve. Pros only use small versions that act as shutoff valves for fixtures such as sinks and toilets and outdoor sillcocks. Flow is inefficient because of the circuitous route the fluid (water, in most cases) has to follow. It's important to orient the valve in the right direction with the arrow (cast into the side of the valve) aligned with flow direction. That way, water flows against the bottom of the rubber gasket. If the valve is put in backward, the flow will force the gasket away from the top of the valve.
