Lathe for home – how to choose?

In order to purchase a high-quality device that will serve for a long time, you need to pay attention not only to technical specifications, but also for specialization. Select according to what work you plan to do on it.

More powerful models save time on processing the product, but also consume more electricity.

The weight of the unit plays an important role. Lighter models may be less stable and may not be able to handle difficult jobs.

The asynchronous motor type is characterized by a longer service life.

Dimensions are important when work space is limited, so it is better to choose mini machines. If the area of ​​the house allows, then it is better to give preference to larger options, for example, the domestic Caliber models - they are stable and allow processing with longer lengths.

It is better to give preference to models that can be upgraded and expand their functionality.

When purchasing foreign-made units, you need to take into account the possibility of repairs, find out whether spare parts are available for free sale, and the presence of a service center in the city.

Rules for choosing home equipment

When choosing a turning unit for use at home, you should pay attention to some recommendations that will help you purchase a reliable and functional unit:

In addition, you should pay attention to the following points:

1. Intensity of use. If you plan to use the device rarely, you should not choose a powerful model.
2. Accuracy of speed control: the more accurate it is, the greater the choice of processed materials and the better the processing.
3. The power of the unit will depend on the type of material used for work.

Advice!When choosing a machine, you should focus on Russian manufacturers: their products are easier and cheaper to operate, since service centers and spare parts with consumables are located in Russia.

No less important criterion when choosing equipment is its price lathe.

Even though it's not professional device, the price of a mini-machine can reach several hundred thousand rubles.

Therefore, you need to proceed from your financial capabilities.

You need to choose a machine with availability necessary functions, but not the lowest price category.

In order for the equipment to serve for a long time and uninterruptedly, it is necessary to properly maintain it before and after completion of work:

1. Before starting the unit, you should check if there are any problems. The launch is carried out only after the breakdown has been eliminated.
2. The lead screw and cutting slides must be lubricated with special oil: daily for three- to four-hour use and twice a day for more intensive use.
3. As work is completed, chips should be removed, the surface of the machine should be cleaned, and cutting tools should be removed from the equipment. All components are wiped dry, drive belts are checked for wear.
4. The condition of the protective cover should be checked regularly.

IN conditions of limited space for the home craftsman the best option becomes for the garage in a basic or extended configuration. Manufacturers and modifications of equipment on modern market quite a lot. Therefore, below are recommendations from experts on choosing a mini-machine for metal turning.

Selection criteria, types

A metal lathe for a garage can save both the operating budget of a car, a household plot, and time. The search for small things that are necessary for repairs and construction often takes several days. If you have the equipment, you can do all this yourself. The main selection criteria are:

• purchase budget – most often the basic equipment is purchased, additional functionality is purchased later, as needed; if you have sufficient funds, it is better to choose a multifunctional (universal) machine right away;
• Dimensions are approximately the same for most manufacturers;
• quality - it is not recommended to buy such equipment to order, it is better visual inspection, a trial run of purchasing methods has not been invented;

• desktop - minimal functionality, some models do not include a tailstock;

• school - various configurations, 2 step speeds with smooth adjustments inside each of them, reverse, weight within 200 kg;

• screw-cutting lathes - minimal spindle runout, high price;

It is very difficult to focus on the size of the workpieces that can be clamped in the jaws of the chuck and placed between the centers of the headstocks. The needs of each craftsman are different; from time to time it is necessary to process large parts or perform jewelry operations.

Specifications

A tabletop garage metal lathe most often has the following performance characteristics:

• power button - may be absent (for example, in the Corvette-2 model), rotation is activated by a rheostat that regulates the speed
• Dimensions – length 1.2 – 1.7 m, width 0.5 – 0.6 m
• weight – within 120 – 200 kg
• workpiece diameter – 10 – 20 cm above the bed or 5 – 15 cm above the support
• center-to-center size RMC – 20 – 50 cm
• drive power – 0.15 – 0.6 kW

Desktop option

For a metal lathe for a garage, 220 V asynchronous or commutator motors are used. The designs of speed control systems and transmission of torque to the caliper shafts differ significantly from different companies. In some modifications, the reverse is switched by a lever, in others, to obtain reverse rotation you have to flip the transmission belt.

Most lathes only cut metric and imperial threads in one direction. Of the domestic manufacturers, the most popular are “Home Master”, “Craftsman”, “Caliber”. All other products, regardless of the brand’s homeland, are manufactured in China - “Optimum”, “Corvette”, “JET”, “Proma”, “DIY”.

For example, the Enkor company produces turning and milling modifications of the Corvette 407, lathes Corvette 401 - 403. Automatic caliper feed is used only for thread cutting; processing and roughening is carried out manually. The chuck is equipped with straight and reverse jaws; parts can be clamped without a chuck in the centers. The smallest of them (Corvette 401) is equipped with a 0.5 kW electric drive, speed 2,500 rpm, electronic system, allowing you to maintain the same speed under any load. A through hole in the spindle allows processing 20 cm of parts.
