What is parallel turning on a lathe?
Parallel Turning is a centre lathe cutting process which is performed to reduce the diameter of the workpiece.
What is eccentric turn in lathe?
Eccentric turning on a lathe refers to the turning off the center or not on the normal center axis, it can be done on 3 jaw self-centering chuck or 4 jaw chuck in different situations, the 4 jaw chuck with independently moved jaws allows parts to be moved off-center.
What is meant by eccentric turning?
It can be defined in the other way as, if a cylindrical work piece has two separate axis of rotation, one being out of center at the other, the work piece is termed as eccentric and turning of different surfaces of the work piece is known as “Eccentric Turning”.
How is chamfering done?
Chamfering is making a small cut, usually at a 45 degree angle, to remove a 90 degree edge. Chamfering is used in woodworking, in glass cutting, in architecture, and in CAD, and it’s also a useful tool for deburring. Chamfer is a noun as well as a verb, and is also frequently used as the name for such a cut.
Where can an eccentric turned job be used?
It is used most often in steam engines, and used to convert rotary motion into linear reciprocating motion to drive a sliding valve or pump ram. To do so, an eccentric usually has a groove at its circumference closely fitted a circular collar (eccentric strap).
What is the difference between facing and parallel turning?
In the turning operation, the tool generally reduces the diameter of the cylindrical workpiece, which can be done by cutting into the part for some depth and move the tool parallel to the axis of the part. While facing operation reduces the length of the piece, the tool is moved perpendicular to the axis of the part.
What is meant by knurling?
Knurling is the metal modification process of creating small ridges along a metal object’s surface to improve the ease with which such an object can be physically handled, lifted or gripped.
What will give a chamfered corner?
To Chamfer a Corner by Specifying a Length and an Angle (AutoCAD Mechanical Toolset) You can chamfer a corner by specifying the distance on one side of the chamfer and the chamfer angle. On the ribbon, in the Chamfer Options panel, check the chamfer length and angle values.
Why is chamfering important?
Chamfering eases assembly, e.g. the insertion of bolts into holes, or nuts. Chamfering also removes sharp edges which reduces significantly the possibility of cuts, and injuries, to people handling the metal piece.
What is shoulder turning?
Shoulder Turning: When a workpiece has different diameters and is to be turned, the surface forming steps from one diameter to the other is called the shoulder, and machining this part of the workpiece is called shoulder turning.
What does eccentric turning on a lathe mean?
What is Eccentric Turning? Eccentric turning on a lathe refers to the turning off the center or not on the normal center axis, it can be done on 3 jaw self-centering chuck or 4 jaw chuck in different situations, the 4 jaw chuck with independently moved jaws allows parts to be moved off-center.
What is eccentric turning and CNC turning method of eccentric parts?
To solve some special problems in equipment running, eccentric parts and eccentric turning methods are becoming more and more important, and many people searching for how to do eccentric turning on the CNC lathe. Now, dajinprecision.com will introduce what is eccentric turning and CNC turning method of eccentric parts. What is Eccentric Turning?
Is it normal to have deflection in eccentric turning?
Fischer: If you are performing eccentric turning over a long distance, deflection will occur. This is normal in any turning operation. For large part features, you may be creating diameters that you can’t clamp a steadyrest on because the part is so eccentric. These parts can get tricky to machine.
Why do you turn the diameter of a lathe?
The length of bar reduced to this diameter was long enough give the chuck something to grip in the next step. This diameter often forms the working surface of an eccentric so time was taken to get a running fit in the mating part. Turning the diameter Final diameter Parting off the blank
