After providing some general information on what a lathe accomplishes, we will provide more advice on selecting a lathe that is appropriate for a specific job. To begin, we will briefly discuss the lathe’s history before exploring a metal lathe for sale.
In their original incarnation, lathes were manual machines that required the cooperation of two people to operate. Considering that the earliest version existed in ancient Egypt more than three millennia ago, it is reasonable to assume that things were somewhat more archaic at that time.
Even the first lathes featured the essential characteristic that is shared by all lathes, from their inception to the present day: unlike other machine tools, in a lathe, the object that is being cut or shaped (the “workpiece”) is the thing that turns, rather than the cutting instrument. A lathe operates in the opposite manner of a drill. Rather than a rotating cutting bit biting into an adjacent piece of wood or metal, a stationary cutting head moulds a piece of metal spinning around under its power.
Because of the way a lathe is constructed, the process of giving a workpiece the desired shape on a lathe is referred to as “turning” the piece. Lathes can work with almost any material, although the most popular ones are metal and wood.
The Industrial Revolution ushered in a period of tremendous technological advancement for lathes, which had previously been relatively simple machines. Lathes achieved more significant levels of power thanks to steam engines; however, lathes may be improved even further with the application of electricity. In the 1950s, servomotors were introduced to the turning process as a way to provide more components of control. Nowadays, lathes are fully integrated with Computer Numerical Control (CNC), which enables them to be entirely automated.
Along the process, craftspeople experimented with the various uses that a lathe could have. Using lathes makes it possible to remove material to form rounded shapes. With a lathe, irregular chunks of material can be turned into anything from metal shafts to wooden chair legs. Lathes may be found in virtually any industry today, from high-end woodworking shops to cutting-edge factory floors. Lathes are used for various tasks, but they all operate according to the same fundamental principle: a rotating workpiece with a fixed cutting head.
It comes with a thread range from 0.4 to 2.0 millimetres, a fully-featured carriage, beautifully machined ways, a self-centring 3-jaw chuck, an MT3 spindle taper, and an MT2 tailstock taper, among other things (10 thread pitches). Because of its capacity of 5/16 inches, the tool post can hold up to four cutting tools at once, allowing for easy tool swapping in the middle of a project. For a higher level of safety, the Baumr-AG comes equipped with a chip tray, splash guard, and emergency stop button. In addition, it comes with a digital LCD that allows for exact observation of the RPM that is now being used.
Suppose you are thinking about purchasing a lathe. In that case, the first step you need to take is to visualize the major project or projects you will use the lathe for. Keeping in mind the project at hand, the following are some questions to ask that will help you select the appropriate lathe.
Do you primarily cut pieces of wood, or is this a metal-cutting lathe you’re using? Will it be in a private garage workshop or a state-of-the-art machine and tool shop? Do you require complete automation, or would a straightforward machine be sufficient? The complexity of the lathe that you’ll need to acquire is determined in part by these considerations. A straightforward, two-axis lathe that is used for turning furniture is very different from a complete computer numerically controlled (CNC) equipped lathe that can handle industrial-sized components along four axes and has various heads for turning, drilling, and cutting.
Featuring a 400W power supply for trouble-free operation, variable speeds ranging from 50 to 2500 pm, and both forwards and reverse rotation. A heavy-duty cast-iron bed equipped with a quick-change gearbox and a carriage has all its features (80mm 3-Jaw Chuck). In addition, a chip tray and a backsplash guard are included, as well as five different cutting tools and a centring drill.
It is located on the side of the lathe (Left-hand side). It is responsible for securing the spindle in place, typically using bearings with power to rotate the spindle. The part is often provided by the headstock equipped with a motor. The diameter of the spindle can range anywhere from half an inch to one and a half inches.
The maximum diameter of the workpiece that may be turned on a lathe is directly proportional to the size of the spindle. A spindle measuring one inch may be adequate for your smaller projects. Still, to get a solid spindle to hold more oversized items without bending, you’ll often need one measuring at least one and a quarter inches.
Other things to think about concerning the headstock and the spindle include the following: does the headstock permit outboard? The outboard enables the workpiece to be positioned away from the piece’s body.
Because of this, the diameter of the parts that can be turned is significantly increased. It’s not the best solution, but there are excellent reasons why pieces are commonly installed over the lathe bed. That’s where the tool turret is, and the tailstock helps support the workpiece. It’s not the best fix, but it gets the job done. When shopping for a lathe, it is essential to consider the dimensions of the headstock and spindle and the range of possible orientations for the headstock. Some headstocks can spin, which makes outboard on some instruments easier.
The Baumr-AG BMLAT-07 is the metal lathe best suited for model makers, toolmakers, and the weekend machinist searching for a versatile and dependable machine that does not take up an excessive amount of space in the workshop.
The cast-iron bed and componentry of the Baumr-AG 7″ x 14″ lathe. Make it a heavy-duty piece of machinery. This tiny metal lathe makes quick work of drilling, cutting, threading, and turning thanks to its high and low gears, infinitely variable speeds, and maximum rotational speed of 3000 rpm. It can also operate in reverse at all speeds, allowing left-hand threading to be a viable alternative. You will have no problem fabricating small parts, threaded parts, fittings, and dies out of brass, bronze, aluminium, and steel, thanks to the 600W of power available on tap and the adjustable power feed.
The chuck holds the workpiece in place, and most lathes can accommodate workpieces with lengths ranging from 5 to 66 inches. Most chucks also feature a through-hole, which enables more extended parts to be sent through the chuck and out the back of the lathe. You should go through the same decision-making process with a chuck as you did with the headstock.
Take note that chucks also come with additional customization choices. Most chucks have jaws, moveable pieces that can be adjusted to a tighter or looser fit depending on the workpiece. The jaw arrangement on each chuck typically consists of three or four jaws, but some chucks have many more jaws than that. The jaws can be adjusted independently of one another or drawn closer together to help grasp objects with an unusual shape.
Drilling, cutting, threading, and turning are all simplified because of this device’s sturdiness. It can also operate in reverse at all speeds, allowing left-hand threading to be a viable alternative. You will have no problem fabricating small parts, threaded parts, fittings, and dies out of brass, bronze, aluminium, and steel. Thanks to the 400W of power available on tap and the adjustable power feed.
It comes with a thread range from 0.4 to 2.0 millimetres, a fully featured carriage, and beautifully machined ways. And a self-centring 3-jaw chuck, an MT3 spindle taper, and an MT2 tailstock taper. It also features an MT2 tailstock taper (10 thread pitches). Because of its capacity of 5/16 inches, the tool post can hold up to four cutting tools at once, allowing for easy tool swapping in the middle of a project.
Because it is equipped with a geared drive and a DC motor rated at 350 watts. It has more than enough power to drill, deep mill, and face mill easily. Milling may be done with a fine feed, and drilling can be done with a coarse feed. You can use the quick-adjust depth limiter if a precise hole location is necessary.
Handwheels and T-slots on the precision-machined working table make it possible to clamp workpieces with dimensions of up to 300 mm x 200 mm x 200 mm. Also, the X and Y axes can be moved with a degree of accuracy within a thousand of an inch. For your convenience, the column can be adjusted to either side up to 45 degrees from the upright position.
There is a clear spindle guard, a chip guard made of rubber ways. And an off switch to ensure the utmost level of safety. The Baumr-AG has a keyed drill chuck of 13 millimetres as standard equipment. It is prepared to accommodate MT3 collets to secure a wide variety of cutting tools.
There are two primary choices: the traditional British flatbed and the more common American v-bed. Both types are self-explanatory, and each of these designs has its own set of supporters. It doesn’t make much difference to the lathe’s performance, particularly when it comes to smaller lathes (and, consequently, smaller workpieces).
The beds can also be rounded on more significant, more industrial-oriented lathes, and slant-bed lathes are becoming an increasingly regular sight on fully automated CNC lathes used in industrial applications.

The dimensions provided do not refer to the lathe itself; instead, they describe the maximum size of the workpiece that may be turned on the machine. The actual lathe will be substantially larger. A lathe with dimensions of 3 inches by 15 inches can easily weigh more than 30 kg; a lathe with dimensions twice as large would weigh far more and would require an engine lift or a small crane to get into position.
When shopping for a new lathe, the motor is one of the last things you’ll need to think about in terms of power. Although many lathes have variable speed settings, there are still those that only function at a single speed. There is also the issue of torque that needs to be thought about.
Your lathe will require more than just high RPMs to cut more significant parts; it will also need the power to keep a heavy workpiece spinning and cutting smoothly. The manufacturer generally advertises the maximum RPMs that a lathe is capable of. Still, the minimum RPMs are required for some processes, such as screw-cutting.
Purchasing a lathe can be a challenging endeavour. Still, you will be able to make better decisions. And save a lot of time when you keep the project in mind as you shop. For what purpose do you intend to make use of the lathe?
With that particular project serving as the deciding element. The required level of complexity of the lathe, as well as any size or weight limits. This will become clear if you have your project’s requirements at all times forefront of your mind. Then you’ll be able to make a far more well-informed conclusion.
