So now, we hope that we have cleared all your doubts about Chuck. 14 Different Types of Lathe Cutting Tools.Lathe Machine: Parts, Types, Operations, Accessories, Attachments.22 Different Types of Lathe Machine Operations.Cutting speed, Feed, Depth of cut, Machining time in lathe machine.In four chuck heavier workpieces can be turned. Four-jaw chuck has more gripping power than a three-jaw chuck In three-jaw chuck, heavier workpieces cannot be turned. Three jaw chuck has less gripping power than four jaw chuck. Four-jaw chuck has better centering, accuracy than a three-jaw chuck. Three-jaw chuck has lower centering accuracy. ![]() ![]() In this, the workpieces can be set for eccentric turning. In three-jaw chuck, the workpieces cannot be set for eccentric turning. Four-Jaw chuck has four holes for the chuck key to control each jaw at one time. The three Jaw chuck has one hole for the chuck key to tighten or loosen the jaws’ grip. In a four-jaw chuck, a higher depth of cut can be produced. Depth of cut is relatively less in the three-jaw chuck. Difference between Three jaws and Four-jaw chucks Three-jaw chuck Four jaws chuck Jaws on the three-jaw chuck move all at equal time On four jaws chuck, jaws move separately. It has centering jaws which have operated by rotating a key. The chuck is held either in headstock or tailstock spindle. The mechanism incorporates a hydraulic or air cylinder mounted at the back end of the headstock spindle and rotates with it.Ī drill chuck is sometimes used in a lathe for holding a straight shank drill, reamer, or tap for drilling, reaming, or tapping operation. It is used in mass production work for its fast and effective gripping capacity. This type of chuck is shown in the figure. These chucks are commonly used in capstan and turret lathes. Different sizes of collectors are used for holding different sizes of the bar stock. And the workpiece is securely and accurately held in the chuck. When the key is turned from outside, the collet is drawn in resulting in the split tapered end being pushed inward due to the springy action. The workpiece slots move here from one point to another for operation, whereas in the shaper machine the workpiece slots were in a stationary. It is similar to the shaper machine but in case of size, the planer machine is larger. The outside surface of the collet which is tapered fits in the taper hole on the body of the chuck, and the tail end which is threaded meshes with a key. Definition Of Planer Machine: Planer is a machine tool used for producing accurate flat surfaces and cutting slots. Depending on the shape of the work that will pass through it. The inside bore of the collet is cylindrical, hexagonal, square, etc. The chuck attached to the spindle by a nut consists of a thin cylindrical bushing known as a collet having slots cut lengthwise on its periphery. ![]()
