Types of Manual Lathes
To select lathe machines that will boost wholesale profits, you need to:
1. Know the Types of Conventional Lathes
Manual lathe manufacturers classify lathes as follows:
- Engine Lathe or center lathe
- Speed Lathe
- Turret Lathe or capstan lathe
- Bench Lathe
- Tool room lathe
They also name lathes by the workpiece material. For example, manual metal lathes are for steel, brass, and aluminum while manual wood lathes are for turning wood.
2. Understand the Pros and Cons of Each Lathe

How to Choose Manual Lathes for End Users
Consider these factors before selecting a manual lathe for your clients:
Select lathes that have the machining capacity for your clients’ workpiece materials. For instance, choose a speed lathe of 3000 to 4000 r.p.m for clients who need to process wood or light metal pieces. A center length that runs at 2000 r.p.m with a rigid construction is suitable for turning, drilling, or facing metals like aluminum, steel, iron, or brass.
Maximum Swing and Max. Length of Workpiece
Typically, an engine lathe size specification has two dimensions – one number for swing and the other for the distance between the center of the headstock and tail post. The swing is the largest workpiece diameter.
A specification like “8 x 42” means that the machine can turn a workpiece of 8 inches in diameter and length of 42 inches. Note that some manufacturers specify the lathe bed length as the second dimension. So, choose lathes with adequate swing and length for the largest workpiece.
Workpieces and Operations Required
Select a center lathe for machine shops that perform repairs on shafts, threads, and bearings. Turret lathes are suitable for shops that handle batch jobs with repeated turning or boring operations. Bench lathes are ideal for making or fixing parts for hand-held fans, toys, disc players, and consumer electronics.
Size of Headstock and Spindle
The headstock and spindle should match the size of the largest workpiece the client will turn. Typically, the spindle size varies from half an inch to one and a half inches. Find out the compatibility with different jaw chucks and collets.
Chuck Size and Design
Apart from the lathe’s swing, the chuck size also affects the size of material the lathe can turn. If a lathe has a swing of 12″ but the chuck hole can only take 10″ when it is fully open, it can only hold a workpiece of 10″.
Note that chucks are seldom interchangeable, and on a center lathe, fixing the workpiece in the chuck takes significant time and effort. So, ensure that the chuck size is suitable for the workpiece and that the chuck keyhole is in a convenient position.
Dimensions of Lathe Bed
Choose lathes with long lathe beds for long drilling shafts and threads used in the oil and gas industry. Long lathe beds are also ideal for turning shafts for large trucks and trailers. For such jobs, select a toolroom lathe.
For shorter workpieces that are not more than 1 or 2 feet long, a standard engine lathe or bench lathe will provide enough room for the workpiece and tool carriage.
Tailstock for Long Workpieces
Tailstock spindles don’t move. But they provide balance for long workpieces. To prevent distortion, while working on a long mining drill, the tailstock must support the workpiece during threading.
For clients that don’t intend to work on long, heavy workpieces, a lathe without a tailstock may be more economical.
Turret size determines the number of tools the operator can set-up in advance. A turret may hold between three to six tools at a time.
Before selecting a turret lathe, determine the number of operations the client needs to perform on each workpiece. However, selecting a large turret with six tool holders is safer when the number of operations is unknown.
Industrial lathes come with a 3-phase power component. Other lathe power options include single-phase AC and brushless DC power. For most short-run jobs, the single-phase power supply is adequate.
Lathes are heavy equipment. A small lathe with a 3″ by 15″ dimension may weigh up to 30 kg. A 16″x33” lathe can weigh over 1 ton (1000 kg). Industrial lathes may weigh as much as 5 tons. However, a heavier lathe usually has better rigidity than a lighter lathe, so it’s usually more accurate.
Manual lathes have strong business potential for wholesalers and drop shippers. The rising demand for auto repair services will continue to increase consumer requests for manual lathes.
