The main difference is the following: On a CNC Lathe the material to be worked is held in a chuck and rotated around and the tools are clamped. These tools are then moved against the rotating material to cut into it. On a CNC Mill the tools are held in a chuck and rotated around and the material to be worked is clamped. These tools are then moved against the stationary material to cut into it.
reaming can be done on lathe machine - only precaution taken is the reamer is not drawn back till the reaming is complete. Proper coolant is used and the rpms are maintaind slow
The 4-Jaw independent chuck. Due to its independent jaws it can grip the most complex shapes. 3-Jaw and 4-Jaw self centering chucks are only capable of gripping cylindrical and hexagonal (3-Jaw self-centering) or cylindrical, square and octagonal (4-Jaw self-centering) shapes.
A milling machine basically look like a drill press, but with the ability to move the work piece sideways. A lathe clamp and spin the work piece horizontally and use a stationary tool bit to cut and shape the work piece.
CNC TURNING M/C-- IN CNC TURNING MACHINE JOB WILL NOT MOVE ( CAN BE ROTATE ), JOB WILL BE ROTATE AND WE CAN MACHINING ONLY IN CIRCULAR PROFILE, WE CAN NOT MACHINING IN RECTANGULAR TYPE PROFILE etc. .IN CNC TURNING , MACHINING WILL ONLY IN 2 AXIS ( X and Z ).CNC MILLING M/C-- IN CNC MILLING MACHINE JOB WILL MOVE ON THE BAD , JOB CAN BE IN ANY SHAPE AND WE CAN MACHINING OF DIFFERENT TYPES OF PROFILE LIKE RECTANGULAR PROFILE etc., WE CAN MACHINING IN AT LEAST 3 AXIS ( X, Y and z ).
I certainly don't think that is true. In practice it is easier to machine anything that has an even number of sides, since the opposite side are parallel.
it is an old machine.It can be ised for various operations like turning,taper turning,knurling,slotting,facing,threading etc. But it can be used mostly only for cylindrical jobs. you can find it in many small workshops.
Without knowing what the question is, I provided a couple of sites that might help:The headstock of a centre lathe can be opened, revealing an arrangement of gears. These gears are sometimes replaced to alter the speed of rotation of the chuck. The lathe must be switched off before opening, although the motor should automatically cut off if the door is opened while the machine is running (a safety feature).The speed of rotation of the chuck is usually set by using the gear levers. These are usually on top of the headstock or along the front and allow for a wide range of speeds.However, sometimes the only way to set the lathe to a particular speed is to change the gear arrangement inside the headstock. Most machines will have a number of alterative gear wheels for this purpose.* http://www.technologystudent.com/equip1/mlathe1.htmThere are many variants of lathes within the metalworking field. Some variations are not all that obvious, and others are more a niche area. For example, a centering lathe is a dual head machine where the work remains fixed and the heads move towards the workpiece and machine a center drill hole into each end. The resulting workpiece may then be used "between centers" in another operation. The usage of the term metal lathe may also be considered somewhat outdated these days, plastics and other composite materials are in wide use and with appropriate modifications, the same principles and techniques may be applied to their machining as that used for metal.* http://en.wikipedia.org/wiki/Metal_lathe
whatever machine products which cant be made using lathe(in lathe only designs symmetrical to the axis of the workpeice or object can be only made) almost any design can be mabe even very complicated designs are economically made using casting or moulding process but even for that the die or mould into which the molten metal is poured to take shape is made using milling machine
Although the planer and shaper are able to machine flat surfaces,there is not much overlapping in their fields of usefulness. They differ widely in construction and in the method of operation. When two machines are compared the following differences may be seen:1. The planer is especially adapted to large work; the shaper can do only small work.2. On the planer the work is moved against a stingray tool; on the shaper the tool moves across the work which is stationary.3. On the planer the tool is fed into the work; on the shaper the work is usually fed across the tool.
In the original Jaws film, only 5 people died :)
Machine tool represent machine itself such as milling machine, lathe machine. Cutting tool is the component of machine tool.
