When you buy a CNC lathe there are many questions to need to look upon before you begin the process. Few of them may be very obvious: what size chuck should I go for? How much travel axis do I require? The size of the spindle bore, the number of tool stations o the turret, etc. Moreover there are other specifications which are important but not very obvious like the maximum swing distance that the work will need, the turning diameter for the family of parts, the spindle horse power and torque that the work may consume etc. The former sets of queries are easier to answer but the latter requires an understanding of lathes.

There are numerous highly skilled CNC lathe machinist who can work wonder on the milling machine but they fail to understand the meaning of basic lathe terminologies. In this article I will attempt to clarify the benefits and the meaning of the not so important features that prevail on a lathe spec sheet along with their definitions and explanations why they might be crucial consideration while purchasing CNC lathe machines.

Maximum turning Diameter:

It means the largest size of the part that could be turned on the machine utilizing the standard length tool without any collision or interference of other machine parts. The size of the part that could be turned safely with the x – axis retracted positively. For example: if you are finding a machine with maximum turning diameter of 16 inches and the parts to be run on a daily basis are 15 inches of diameter , which means you would want a machine with maximum turning diameter. In the above example the part would technically fit but if you must be aware that you are running on the very edge of the envelope and that if you want to hang a tool out of the turret than the normal, it is likely that you might not have enough X-axis travel to accommodate the part.

Maximum Swing:

This means the largest diameter part which could be spun in the chuck without any interference with cross glide, guarding or other components of the machine near the area of chuck. This value could be larger than the maximum turning diameter depending upon the design and style of the machine.

Horse power and Torque:

Horse power and torque are one of the necessary considerations while purchasing a CNC lathe but not in all cases. If you are into castings, forgings, drilling large diameter holes in steel then torque and horse power are very important elements and you must be sure that your machine has enough for your application.

Maximum turning Length:

It is as same as the maximum turning diameter. This indicates the longest part that could be turned based on the axis travel and mechanical limitations. For a particular part to have an effective maximum turning length could be less than that specified by the use of large or deep chucks or the tool that hangs out from the turret. In both circumstances there would be a possibility of mechanical interference restricting the length to be machined.


Know In-Detail About Basics of CNC Engineering

To start with the basics, CNC stands for computer numerically controlled. The CNC machines are used for engineering. People in various kinds of industries use these kinds of machines all across the globe. The computer controlled machines were created with the basic objective to detect things that the human eye could not detect. As we know, the computer controlled machines are highly capable of detecting and carrying out those functions, which the human eye might not be able to notice also. The industries that use machines to manufacture goods have greatly benefited from these computer controlled machines.

The History Behind The Computer Controlled Machines

There have been great changes in technology. As it is obvious, the computer controlled machines are not the first kind of invention or change in technology. Before the computer controlled machines, people extensively used the numerically controlled machines and they were invented in the 1940’s and 1950’s. However, with the change in time and technology, the first ever kinds of computer controlled machines were created and used for the aerospace industry. The time was during the Second World War that these kinds of machines were used by the very renowned aerospace industry. The usage of computers then was very limited as people were not completely computer literate. Also, not a lot of people could afford buying such expensive computers or machines. If the scenario is compared with today, there are huge numbers of people who use computers as it one of the greatest inventions of technology. Computers have undoubtedly made lives much more easier and comfortable.

What Is Modern Computer Numerically Controlled?

There is without a doubt, great difference before the primitive and the modern kind of computer numerically controlled machines. The modern kinds of computer numerically controlled machines are used for precision engineering. It is mostly used for keeping a track on the accounts of production. Manufacturing, sale, profits etc. the machines are used extensively as people can no longer keep a track on their business accounts. As times have changed, people are more reliable on their computer systems more than the human mind. The human mind is still capable of storing a lot of data and information. But, as people are much reliable on their systems, there is hardly any kind of business firm that does not keep systems with them.

Less Labor More Machinery

Though with the invention of the computer numerically controlled machines, the amount of labor required in a factory set up has definitely reduced as most of the work is done by the machines only. The machines are capable of doing the same amount of work that some labor when coupled up would do. The real challenge is to hire less labor but the labor that is appointed needs to be computer literate and they must also have the know how of using the machines so that they are used to its fullest capacity. If one does not know how to use the machine, then the machine is next to being useless. So people need to be in complete touch with technology so that they can use the machines to their fullest capacity and capability. Modern CNC machines might be a little complicated to use, but it is a proven fact that these machines are of great benefit to the industries. Also, the machines can be used by people from any industry, there is no restriction that the computer numerically controlled machines need to be used only by particular industries for particular uses. The uses of the machines are best for precision engineering so as to produce the desired results.

The Importance and Usage of Precision Machining

The masses of objects often used, comprises of complex pieces composed through precision machining. They are generally the items assembled for the construction of other products – tiny as well as big, cell phones, appliances, cars and airplanes. Furthermore, these items or components are not the final product as they develop more products for making the new technologies capable of functioning. Components with high accuracy are made in the industry by the companies, depending upon the quantity of requirement – (large or small).
