Fast forward to , over a century later, and we have computer-aided, or computer numerical control (CNC) machines that are taking over the production process entirely. One such machine is the CNC lathe, which quickly replaced traditional multi-spindle lathes to become one of the most versatile, popular tools in use today.

A Brief Introduction to CNC Lathes

Computer controlled lathe machines are essentially a modern take on a century-old tool — the manual lathe. The lathe spins the raw material along one axis (vertical or horizontal), while the cutting tool attached to it gives the material the desired shape.

• Sizes available — Like mills, CNC lathes can be found in multiple sizes and shapes, from tiny machines to full-form lathes that take up an entire room. Miniature, handheld versions are often used by watchmakers and jewelers, while the bulkier versions are a staple in CNC machine shop.
• Materials used — CNC lathes can be used for a wide variety of materials. With the right material, you can achieve any kind of intricate design or shape. Below are a few commonly worked materials.
• Wax for creating prototypes — Machinable wax, plain paraffin, and beeswax
• Wood — Lathed wood has a beautiful look and feel
• Plastics — Delrin®, acrylics, and Teflon™
• Metal — Aluminum, brass, and stainless steel

Types of Lathes

• Engine lathe — A popular type of lathe suitable for low-power operations; reliable and versatile; works on a wide range of speeds and feeds
• Centre lathe — Involves levers and gears that manage spindle speed; not an especially popular option
• Gap bed lathe — Can easily accommodate larger workpieces due to a removable bed section that forms the base of this machine
• Speed lathe — Faster, lighter version of modern CNC lathes, only including a headstock, tailstock, and tool turret
• Bench lathe — Another lighter, smaller variety; can be perched on a workbench for small jobs
• Toolroom lathe — Highly versatile; provides the best finishing
• Turret lathe — Ideal for quick and sequential workings
• Special-purpose lathe — Used to perform heavy-duty, specific tasks

Benefits of CNC Lathes Vs. Conventional Lathes

CNC lathes offer many advantages over conventional machines. Five key benefits are outlined below.

1. No need for highly skilled operators

In the past, working with lathes required two highly skilled operators — one handling the lathe and the other controlling the material. It was a tough job. But now, with the introduction of computers and automation, lathe tasks are a lot less daunting. You need just one operator — someone skilled enough to enter the dimensions onto the machine, adjust the feeds and the speeds, and let the computer (and the machine) do the rest.

2. Full automation, allowing for easier, quicker work

Producing hundreds, even millions, of similar dimensions is easier than ever, thanks to modern CNC lathes. Today, machine-controlled systems enable CNC lathes to produce perfect pieces easier and quicker than ever before. Whether you need simple parts, intricate parts with tight tolerances, or unique, intricate shapes, CNC lathes can handle the job.

3. Highly versatile, allowing for use in the creation of all kinds of products and parts

Unlike manual lathes, CNC lathes are versatile enough to produce nearly any kind of product or part — from sturdy furniture pieces and car parts to delicate lamps and crockery. Shaping cylinders or spheres is easy with CNC lathes, which can even be used to produce replacements parts for other machines.

4. 99.99% accuracy

As less manual labor is involved, the chances of achieving optimal accuracy are pretty high with CNC lathes. This makes these machines a top choice in industries requiring high precision — such as the aerospace, health care, and hospitality sectors. Plus, CNC lathes work with almost every type of material. That said, one can never eliminate all errors, manually or otherwise. That’s why we’ve kept that 0.01% aside.

5. Cost efficiency

While CNC lathes are a lot costlier than manual lathes, CNC models still offer a range of financial benefits, including:

• Low setup costs — Setup costs are a one-time expenditure when working with CNC lathes.
• Machining costs — With CNC machines, you recoup every investment by being able to produce 20x more parts than manual lathes allow in a given time frame.
• Labor costs — Fewer operators are required with CNC lathe work, and they don’t need to be tied to the machines 24/7. This frees up your labor budget for other essential operations.
• Material waste — Less human error means less material waste.

Working With CNC Lathes

Like other types of CNC machines, CNC lathes have found a solid niche in the machining sphere over the last several years, effectively replacing manual and conventional models thanks to the versatility, accuracy, cost efficiency, and easy automation offered.

Advantages and Disadvantages of a Lathe Machine

A lathe machine is a commonly used machine that works through removing the undesired material from a rotating workpiece with a cutting tool that is fed against the work either crosswise or longitudinally to give its desired shape and size. This is also known as the “mother of all machines” and due to its versatility, it can be used in a large variety of operations such as turning, tapered turning, shoulder turning, facing, thread cutting, parting, chamfering, knurling, drilling, boring, counter boring, countersinking, and reaming operation.

Probably the oldest machine tool known to mankind, the first lathe invented worked with one person turning the wood workpiece using rope and the other person shaping the workpiece through a sharp tool, now called as a two-person lathe. The ancient Romans improved this design by adding the turning bow, and the development went on to the industrial revolution when steam engines and water wheels were attached to the lathe to make the turning easier and faster. This paved way for metalworking and heavier machines with thicker and more rigid parts. Then in the s, the servo mechanism was added to be able to control the lathe machine and it became the easiest lathe machine to operate until a British engineer named Henry Maudslay invented the Computer Numerical Control (CNC) lathe which is the most advanced form of lathe machine.

The basic parts of a lathe machine are the bed, headstock, tail stock, carriage, saddle, cross slide, compound rest, tool post, apron, chuck, feed rod, lead screw, spindle, and leg. Its main purpose is shaping a product through removing the unwanted material in a rotating workpiece and a fixed cutting tool. With this, various products such as nuts, bolts, piston, pump part, ram, gun barrels, candlesticks, train parts, cue sticks, wooden bowls, baseball bat, crankshaft, etc. can be made.

Some of the advantages in using a lathe machine are:

• High Productivity – The industries that are using lathe machines can be sure that these produce high quality products with top-notch accuracy, especially the CNC lathe machines. As a result, the productivity will increase.
• High Speed – The machining in the lathe can produce many products in a lesser time, especially with the use of CNC lathe and automatic lathe, because of its high-speed production.
• Saves Time and Money – Due to the advantages mentioned above, using a lathe machine saves a lot of time. Aside from this, it also saves money because there is no need to have many operators or turners which will result to lesser machining and labor cost.

Some of the disadvantages in using a lathe machine are:

• Highly-skilled Operators/Turners – Although it only requires a few turners to operate the lathe machine, there is a need for them to be highly-skilled because they have to control the machine precisely and make sure it is given constant supervision. The preciseness of the job depends highly on the skills of the turners/operators.
• Cost and Weight of the Machine – The initial cost of a lathe machine is high. It actually depends on the purpose and how big the production is but most lathe machines used in big companies cost up to $50,000. It also takes up a lot of space because it is a huge machine and sometimes, it requires extra fittings and attachments which makes it bigger and more expensive. The use of CNC lathe machine is also not advisable for small production.
• Constant Maintenance – A lathe machine needs a proper and constant maintenance, in each of its important parts. Otherwise, this may damage some parts or the whole machine.
• Limited Structures and Shapes – Lathe machines work best with cylindrical shapes, however, there are limited shapes and structures that can be done with it. Also, only one tool can be used generally at a time.
