Master Your Purchase: 8 Things You Must Know Before Buying a Metal Lathe

Spread the love

Are you considering purchasing a lathe? Choosing what you intend to accomplish with it and the stuff you will cut is one of the initial steps. Are you a craftsperson wanting to create some wooden salad bowls and candlestick holders?

Your only requirement can be a tabletop wood lathe. However, more robust and adaptable equipment is required if you want to hold better accuracy or cut metals. Continue reading if you fall into the latter category or if you simply want to learn something about accurate lathes in general.

The oldest pieces of metalworking equipment are lathes. In fact, because of their capacity to produce components for other machines, many people regard them to be the parent of machine tools. These include the above-stated candlestick holders, as well as connected screws, shafts, bushings, and many more.

Although early Egyptians are credited with creating the first simple lathes, thread-cutting technology did not become available to them until 1800, according to historians. Although others undoubtedly prepared the ground for his significant work, the Englishman Henry Maudslay is credited with coming up with that invention.

Things You Must Know Before Buying a Metal Lathe

Determining The Size Of The Lathe Machine You Need

Swing and size measurements of lathes are frequently expressed as a couple of numbers (i.e., 14 x 30). The swing, which is the first number, measures the separation between the center of the head as well as the lathe bed. It is the largest radius of a product that may be positioned between centers on that lathe. The workpiece won’t fit between the centers of your lathe if its radius is 150 cm and its swing is 12 inches.

The second figure, which is regularly alluded to as bed size, is the separation between the head and tailstock. The bed size in the aforementioned scenario will be 20 inches.

Make Sure Your Machine Shop Is Up-to Hosting a Lathe

Even small-bed lathes can be rather massive and weigh hundreds of pounds. Even bigger and possibly weighing hundreds of pounds, floor-mounted, heavy-duty lathes are possible. Make sure the footprint of the lathe machine doesn’t exceed the available floor space before making a purchase.

From little bench lathes to enormous, room-sized commercial CNC lathes, lathe equipment comes in all shapes and sizes. Place the latest machinery on your factory floor taking into account the kinds of lathe activities you anticipate.

Ensure your business has more than enough juice for it! Electricity usage for lathes is high. If you are purchasing a brand-new metal lathe for your mechanical workshop, you presumably already have the required power capacity. However, make sure to double-check the power needs if you’re adding a tabletop lathe or tiny lathe to your home workshop.

Get Acquainted With The Parts Of a Lathe

Have you ever wondered what kind of a lathe CNC lathe is? Typically, a lathe machine consists of four main components:

Both fixed and pivotal lathe beds are available. The framework of the lathe is held in place by the lathe bed. The headstock-mounted jaw chucks are used to mount the workpiece. In order to allow the workpiece to freely spin above the lathe bed, the headstock, tailstock, and other mounting centers can be used.

During machining, the workpiece is held in position by the headstock.

Massive pieces of material are supported and clamped using the tailstock.

A lathe machine’s lead screw moves the carriage forward in time with the spindle’s rotation. The creation of threads using a turning tool with a unique design is its most significant achievement.

Workpieces that are “between centers” are those that are supported by that the headstock and tailstock. Occasionally, the lathe bed contains a piece that can be removed below the headstock to enable rotating activities on a workpiece that is larger than the lathe machine’s specified swing radius. 

There are numerous varieties of lathes. The two types of standard-powered lathes are engine and turret. While most lathes can be classified as either metallurgy lathes or woodworking lathes, they often work with a variety of materials. Wood lathes may be excellent machine tools, but they are often not as robust as their contemporary metalworking counterparts.

Know The Lathe’s Capabilities

It would be important to decide what kind of lathe work you plan to do before purchasing a lathe and to be certain that the new lathe is made for those lathe activities. For instance, don’t purchase a lathe machine that has a 44″ maximum capacity if you want to use it to turn operations on a 48″ long crankshaft.

Lathes have been used by people for ages. The lathe was originally used for woodworking, but Henry Maudslay redesigned it for metalworking in the 1800s to accommodate the industrial settings of the Industrial Revolution.

Over time, motor lathes and CNC lathes have grown larger and more powerful, but with the advancement of computer-based numerical control technology, they have also become more versatile.

Using a lathe, the workpiece spins on a spindle while being turned by a cutting tool that is fastened to a cross slide and positioned on a tool post.

Lathes are the best choice for anything that has a cylindrical shape because of their revolving spindle. They can also knurl, thread, drill, ream, bore, sand, and perform other operations.

Modern aerospace, automobile, furniture, and tool manufacture all rely heavily on precise lathes. Lathe machines can do a variety of jobs thanks to their adaptability. Many include adjustable spindle speeds and tool holders, allowing workers to switch out the tooling in the middle of an operation.

High adaptability is another feature of contemporary toolroom lathes, particularly when CNC lathe technology is included. Other machine tools cannot manage the complicated machining operations that these machines can. Lathe machines dominate the contemporary machine shop together with milling machines.

Choose a Belt Drive or Direct-Drive Spindle for Your Lathe Machine

Metalworking lathes can have a direct drive or a belt-driven spindle, but the belt-driven kind is more common among older models of lathes. Shorter cycle times are achieved by direct-drive spindles’ ability to deliver variable-speed significantly more quickly than belt-driven spindles. A workpiece with only a direct-drive rotation speed may reach 6,000 rpm in less time than one that uses a belt-driven rotation speed. Despite this, belt-driven lathes remain a good choice and offer the strength and precision that many machinists need.

Check the Spindle Speed, Horsepower, and Torque

The range of diameters that modern CNC lathes can handle is somewhat narrow. The majority of machine shops buy equipment to accommodate a maximal workpiece diameter. If you’re cutting 2-inch-diameter bars, for instance, the lathe machine will be built for the turning process on varying diameters using 6,000-rpm spindle speeds and the proper amount of horsepower and torque.

As a result of the mass of the product in the jaw chuck, larger lathe machines, on the other hand, will have more torque. Smaller spindle speeds and also more torque is needed for larger workpieces.

Make a List of Turning Tools That You Will Need

Even though the lathe machine is expensive, you still need to make other purchases. A jaw chuck will likely be included with your lathe, but for some lathe tasks, you should also have a faceplate. Additionally, you’ll require a variety of cutting instruments, such as but not restricted to:

  • Tools for turning carbide
  • Tedious bar
  • Chamfering device
  • Facing device
  • Parting device
  • Grooving device
  • Tool for cutting threads
  • Tool with knurled

Buy a Lathe That Will Give You Value For Money

Any manufacturing business or home workshop will benefit from the speed and variety of CNC machines, which are pricy but extremely powerful machine tools. Two CNC lathes from CNC Masters are available and meet all the requirements for both speed and precision. The CNC lathes are made in the USA and offer top-notch customer service.

Conclusion

Yes, you currently have a sizable investment to make. Before pulling up your credit card, consider the broad picture and decide which option is best for you in the long run. Yes, an enthusiast or someone who is just starting up can frequently survive on a machine from a discount brand. But this can turn out to be a mistake when their requirements increase.

Better parts and much less hassle result from spending a little more today on an industrial-quality lathe. In addition to that, a larger, heavier, and more robust machine often costs its owner less money in maintenance and replacement parts over time. In addition to everything else, make sure to do a lot of research and contact us to talk about your project.
