Types of metal lathes

Center lathe / engine lathe / bench lathe
Center lathe, engine lathe and turning all the bench lathe more primitive type of lathe that could be considered class archetypical of machined metal work, most often used by people using a general or hobbyist machining lathe bench title refers to the version of the class This is small enough to be mounted on the workbench (But still complete and larger than a small or micro lathes lathes), turning centers, construction detailed above. However, depending on year of manufacture, size, price range or desired features, lathes, even these can vary between versions.

Lathe Machine
Engine lathe is a lathe used for the late 19th century or 20th century with the traditional feed for automated cutting tool as opposed to the first lathes that are used with hand-held tools or lathes with feed only themselves. The use of "engine" in a sense this is equipment not feel the mechanical mover - prime, as in steam generators with a power source industry standard for many years. Will have the steam engine big one that will provide power to any computer via the shaft line of the belt so early lathes engines generally 'head cone' in the core are usually attached to its pulley multistage called cone pulley. designed to accept a flat belt. Spindle speeds, different can be acquired from the moving belt, flat steps at different pulley cone lathes Cone heads usually have a countershaft (layshaft) on the back of the cone, which may work to set up. lower than the value of the velocity obtained by direct belt drive. These gears are called back gear Large, sometimes turning to the two-speed transmission, which may be moved to the location is still lower than the speed.

When electric motors became common in the early century, 20, lathes cone head, many were converted to electrical energy. Meanwhile, the state of the art in the performance of gears and bearings has reached a point where manufacturers began to focus headstocks fully with gear similar to gear drive to get the speed axis rate and enter the amount higher. while the transmission power required. To take advantage of high speed steel tools.

Of affordable appliances have changed again by means of speed control may be applied, allowing motor speed continuously variable from maximum to almost zero RPM.

Construction of Lathe

Construction
The design of lathes can vary greatly depending on the intended application; however, basic features are common to most types. These machines consist of (at the least) a headstock, bed, carriage, and tailstock. Better machines are solidly constructed with broad bearing surfaces (slides or ways) for stability, and manufactured with great precision. This helps ensure the components manufactured on the machines can meet the required tolerances and repeatability.

What CNC Engraving Machines Are

CNC Engraving Machine
CNC (Computer Numerical Controlled) machines engraving speed and accuracy in design and engraving for industrial metals, plastics, aluminum, graphite, ceramics and most non-ferrous materials. They can be as simple as a home-made drilling for drilling holes or a series of large, complex organizations with tools and tables.

CNC machines are designed to do one or all of unsupervised with a few corporate production unit consisting of a group of machines. When an almost perfect machine could leave discouraged. Many of these machines are designed as a tool to change the self-defined order and change the location of the new elements to finish the job. Manpower problem has been fixed, because these machines can work by yourself all day long.

CNC Engraving Machine
Because they have a computer and perform, CNC Machine is far more accurate and consistent than the recommended system of any of the human machine CNC true error-free because the device is working under the terms of the programming. Project can be done using sophisticated equipment, regardless of the frequency of task is repeated. Products will be completed according to the course at a time.

It is easy to learn and set up a program for CNC machines. What is needed is a guide to enter into a computer program. Setting details of previous work can be restored quickly and easily to time-consuming manual changeovers will not be a problem.

CNC machines typically have two tables, and automatic pallet change. This decrease in valuable time as one element can be machined on one table while the Materials for the new components are loaded into the other. Type of machine CNC is available with a wide range as well as the work they can do, such as opening, drilling ground zero machines that can be carried Milling, boring, tapping, as well as. complex contouring operations.

Type of machinery is not limited, including the type of industry of any of these devices can also be used for working on materials such as wood, plastic, along with the project fabricating metal also has units for use in the system, CNC for the home. General Mills is usually a Lathe or CNC, Table 4 - axis with computers and software for CNC programming and tools required for the use of machinery and equipment This is ideal for those who need to produce a series of small pieces the same CNC machines may be installed on a couple of five-axis up

Rotary Table

Rotary tables are most commonly mounted "flat", with the table rotating around a vertical axis, in the same plane as the cutter of a vertical milling machine. An alternate setup is to mount the rotary table on its end (or mount it "flat" on a 90° angle plate), so that it rotates about a horizontal axis. In this configuration a tailstock can also be used, thus holding the workpiece "between centers."

With the table mounted on a secondary table, the workpiece is accurately centered around the rotary table's axis, which in turn is centered around the cutting tool's axis. All three axes are thus coaxial. From this point, the secondary table can be offset in either the X or Y direction to set the cutter the desired distance from the workpiece's center. This allows concentric machining operations on the workpiece. Placing the workpiece eccentrically a set distance from the center permits more complex curves to be cut. As with other setups on a vertical mill, the milling operation can be either drilling a series of concentric, and possibly equidistant holes, or face or end milling either circular or semicircular shapes and contours.



A rotary table can be used:

•To machine spanner flats on a bolt
•To drill equidistant holes on a circular flange
•To cut a round piece with a protruding tang
•To create large-diameter holes, via milling in a circular toolpath, on small milling machines that don't have the power to drive large twist drills (>0.500"/>13 mm)
•To mill helixes
•To cut complex curves (with proper setup)
•to cut straight lines at any angle
•to cut arcs
•with the addition of a compound table on top of the rotary table, the user can move the center of rotation to anywhere on the part being cut. This enables an arc to be cut at any place on the part.
Additionally, if converted to stepper motor operation, with a CNC milling machine and a tailstock, a rotary table allows many parts to be made on a mill that otherwise would require a lathe.

How to make your own CNC machine at home

introduction
Many said the CNC machine or a computer numerical control brings to mind images that are very complex and why Just look at the pictures of some of the art CNC machines used for industrial purposes. All of these ideas in mind to come with your idea is how can those which are made at home? Better believe me when I say that you can build your own CNC machine at home from parts easily affordable cost just part of reality. (On the flip side is that it will do the work done by sophisticated CNCs on the market), but that should not stop you from doing your own dream home and this is how you should proceed.

Make CNC at home
Why do I need
Do not expect home made machines, similar to what can be done by using expensive commercially produced by large engineering firms. If you are a type of adventure and love to do things by yourself is not why you should not build this machine because, CNC will use in the operation of any of you have asked yourself at home. Do your computers have the ability to do.

Of course, you are targeted as easy as You can not say that my home made CNC should do all the work of the household, all the mechanical problems in the home or to pay your I mean, you can dream big. But that will certainly have more knowledge that I will give you For the rest of the humbler folks feel free to read ahead.

We all want what is carved on wood, plastic or metal, etc. One of the things you can expect your house to do, CNC is to do some simple two-dimensional carving, with you in the media such as plastic or wood.

Budget Consideration
Budget is one of the biggest restraint while making the device used in the household. I think the main reason for this is that although we will not hesitate to spend large amounts of money on equipment made by the company brand; We became misers and want to do at home what should be expressed from thin air. Of course, I can not teach you this magic. Of course, I recommend machine should not cost more than a few hundred dollars, depending on how much things you can collect from your warehouse and how much you need to buy second hand or first-hand market.

So after a lot of knowledge about CNC and CNC machines do, then it's time we look at the CNC machine at home easily in the next article.
