Industrial lathes

What are industrial lathes and what components do they have?

A lathe is the basic machine of any machining workshop. At Heller we have new metal lathes — centre lathes, electronic variable-speed lathes, large-bore lathes and lathes with variable speed — with swings from 360 to 2000 mm. If you are looking for a lathe for your workshop, here is our entire range of lathes.

Industrial lathes are machines designed to thread, cut, machine, rough, turn and groove parts that have a geometric shape by means of revolution mechanisms.

These machines work by rotating the workpiece to be machined, which is held by the headstock of the machine. While it rotates, one or more cutting tools make a regulated movement towards the workpiece, so that swarf is cut according to the machining conditions.

Components of industrial lathes

There are several elements that characterise the make-up of industrial lathes. They are as follows:

Main motor power

This aspect is related to the work the industrial lathe is able to carry out. Only those with a power above 350 W allow professional work.

In addition, the power of the main motor is also related to the maximum outside diameter it can support. This must match the size of the parts that are planned to be machined on the machine.

Swing over bed and swing over cross slide

This is another aspect related to the type of parts that can be machined on a given lathe.

Guideway

Guideways are elements of great importance for the accuracy level of the lathe. Their basic function is that of a seat.

Headstock

As regards the headstock, its power is the most important characteristic, since not all operations demand the same level of power. Therefore, headstocks should be chosen whose power matches the work planned for the machine.

For example, if the plan is to remove or rough only a small amount of swarf, a low-power headstock would be acceptable. However, if the plan is to rough or remove swarf on a large scale, it would be essential to have a high-power headstock.

Gear train and back gears

These two elements work together to make the industrial lathe operate. They need to be checked periodically, since they require maintenance. How often the back gears and the gear train need to be checked will vary depending on how often the lathe is used. To check them, it is enough to inspect their condition by opening the top cover of the headstock.

Carriage

The carriage is necessary for machining and for moving the lathe. It also influences the cutting process, since it incorporates the measuring scales, which are necessary to ensure that every part is cut accurately.

Digital readout

The digital readout is not available on the oldest industrial lathes, but on modern ones it is fitted to improve their operation. Its purpose is to help control the movements of the carriage by means of electronic control down to four decimal places. Thanks to this element, accuracy can be improved further and handling of the machine is simplified.

Quick-change toolpost

The quick-change toolpost is another element that cannot be found on all industrial lathes, but it improves the quality of the machines it is installed on, since it ensures optimum rigidity. When rigidity is adequate, better finishes can be achieved on parts. It should be noted that these toolposts are not limited to offering fast changes, but also have storage space for tool holders.

Types of industrial lathes by control

Industrial lathes can be classified according to how their cutting and travel movements are controlled. At HELLER we work exclusively with manually controlled lathes, a segment in which we have been supplying machines for years to machining workshops, technical schools and manufacturing companies throughout Spain.

Conventional lathes

Conventional lathes are manually controlled machines, operated directly by the operator by means of levers, handwheels and the leadscrew. They allow all the usual metal-cutting operations to be carried out: threading (external and internal), turning, facing, grooving and axial drilling, among others.

Unlike an automated system, on a conventional lathe the quality of the finish and the final accuracy depend to a great extent on the operator's skill: on the control they exercise over the feed rate, the depth of cut and the choice of cutting tool for each material. This is not a limitation when working with robust, well-calibrated machinery: it is, in fact, the reason why many machining workshops still prefer the centre lathe for short production runs, repair parts, prototypes or jobs that require fine adjustments on the fly, something that is harder to change in a fully automated system.

Our lathes feature a hardened and ground bed, a headstock with a high-strength gear train and precision guideways that ensure stability even in demanding roughing passes. The result is a machine designed for intensive workshop use, with a long service life and predictable maintenance.

HELLER lathe range

Among manually controlled lathes, at HELLER we offer different variants according to the needs of each workshop:

• Centre lathes: the base model of our range, designed for turning, threading and facing work in low- and medium-volume production. They combine robustness and accuracy with a learning curve that is accessible for the operator.
• Centre lathes with variable speed: they allow the spindle speed to be adjusted continuously, without having to change gears or stop the machine. This speeds up changeovers between materials of different hardness (steel, aluminium, brass) and workpiece diameters, reducing idle time in workshops with varied production.
• Large centre lathes: versions with a greater distance between centres and swing over bed, aimed at very long or large-diameter workpieces — long shafts, hydraulic cylinders, components for heavy machinery — where additional structural rigidity is required to maintain accuracy on long passes.
• Large-bore lathes: designed to work with larger-diameter through-bar, useful in workshops that machine series of parts from bar stock rather than from individual billets.

All our lathes are supplied with technical advice before purchase, to help you choose the model whose motor power, swing over bed and distance between centres suit the type of part you are going to machine in your workshop.

Frequently asked questions about industrial lathes

What are industrial lathes and what components do they have?

They are machines designed to thread, cut, machine, rough, turn and groove parts by means of revolution mechanisms. Their main elements are the motor power, the swing over bed and over cross slide, the guideway, the headstock, the gear train, the carriage, the digital readout and the quick-change toolpost.

What power should an industrial lathe have for professional work?

A main motor power above 350 W is recommended, always matched to the maximum outside diameter of the parts to be machined.

What is the difference between a conventional lathe and one with variable speed?

The conventional lathe is manually controlled and its final accuracy depends in part on the operator's experience. The variable-speed lathe allows the spindle speed to be adjusted continuously, without changing gears, adapting more conveniently to different materials and workpiece diameters.

Which HELLER lathe do I need for very long workpieces?

For long shafts, hydraulic cylinders or large components, the most suitable is a large centre lathe, with a greater distance between centres and swing over bed, designed to maintain rigidity and accuracy on long passes.
