Features: There is a component that moves in a plane, called a connecting rod.CS SERIES SCISSOR TYPE METAL CUTTING SAW CS-220 Features: ①Use low vice. Surface contact, large load, easy to lubricate, not easy to wear, simple shape, easy to process, easy to obtain high manufacturing accuracy. ② Changing the relative length of the rod, the movement law of the follower is different. ③ Rich connecting rod curves. Can meet different requirements.Vacuum heat treatment process of TC11 titanium alloy pipe Quick return exercise In the crank-rocker mechanism, when the crank and the connecting rod are collinear twice, the rocker is in two extreme positions, referred to as extreme positions.How to Update your heat treatment The angle 0 between the two cranks is called the extreme angle.
