Thread-cutting machine is used in various fields of production. The range of these products is quite wide: from domestic models to foreign counterparts. What product characteristics should I look for when choosing? Consider also the features of some models of machines.
What is a threading machine and where is it used?
In order to create special threads on studs or bolts, metal or non-metal products, as well as on pipes of various diameters, a threading machine is used. The type of thread on small parts depends on the speed of the electric motor in the device. The speed of rotation depends on the spindle, which directly affects the duration of the threading operation.
The scope of these devices is quite wide. They can be used in industry, mechanical engineering, machine tool building, during repair or plumbing work, and in many other industries where small parts with unique and unique threaded threads are required. Due to the fact that there are many varieties of machines that differ in both the nature of the work and the price, they are quite popular both in large industrial enterprises and in companies involved in small-scale production.
Main characteristics
To choose the right drilling and threading machine, you need to know the conditions of its operation and productivity, that is, how many parts it can process in a certain time. All this depends on the technical parameters of the selected model.
The main properties of the machines:
- power (the thread cutting speed directly depends on it, for small and serial production of parts it will differ);
- spindle rotation speed (in any machine there are several rotation speeds from 27 to 500 rpm);
- a range of cutting parameters (often it is necessary to cut a thread of different diameters, so the machines are initially programmed for a certain range of cut threads);
- the weight of the machine (it can be either a stationary heavy installation (up to 150 kg) or a compact version (only 50 kg), which can be easily transported if necessary).
As a rule, stationary installations of a thread-cutting machine are selected for mass production, since they have more power, can work for a long time and in intensive mode. In order for it to last longer, it is worth periodically lubricating the device with automatic lubrication.
Also, all devices for threading can be divided into internal (producing holes inside the product) and external (working only with the outer layer).
Features of choice
A correctly selected thread-cutting machine is a device that satisfies all the necessary production needs with its work. In order to choose a truly suitable model, it is worthwhile to determine in advance the possible scale of work.
So, there are fully automated machines that work without the intervention of an employee, while doing their job more intensively. They are intended for mass production. In addition, such large stationary machines have additional options in the form of drilling, which greatly facilitates the process of creating blanks. But such devices are expensive and needed when it is planned to cut thousands of threads every day.
Portable types or desktop threading machines have a small weight (50-70 kg), so they can be easily transported, are inexpensive, but their functions are somewhat limited. Such devices are needed in order to cut the threads periodically and in small quantities. As a rule, such installations are used when carrying out repair or plumbing works, replacing pipes.
Models of domestic production
Domestic machines are of good quality, long service life and are designed for high-precision threading.
This is a compact thread-cutting machine of Russian manufacture (the weight without accessories is only 22 kg), it has additional overload protection and a movable magnetic base. According to user reviews, this mobile device does a good thread depending on the selected diameter, but is not intended for mass production.
Hand-held tabletop tapping tool, weight 80 kg, spindle speed from 520 to 790 rpm.
A stationary machine that is used for threading water or gas pipes. Its weight is 420 kg. It can be both standard sizes and custom-made. It is used in serial production under intense loads.
Among domestic thread-cutting machines for pipes, according to user reviews, such a range of JET and PROMA, which has its own specifics of working in semi-automatic mode, still stands out.
Foreign models
The price of foreign models of machine tools is slightly higher, but such models have good quality, extended functionality, a long service life and the ability to choose the suitable option from a number of various modifications of devices.
It is distinguished by reliability, easy to operate, has several modifications, both stationary and mobile, among which users have noted the Magnum model.
Depending on the size of the head for the threading machine, the thread diameter can be up to four inches. Regardless of size and model, the machines of this brand have only positive feedback from users and are intended for both small-scale production and serial production of parts.
Designed for threading pipes up to 50 mm, has a self-priming pump, designed for standard threading.
It has a powerful engine, power up to 40 rpm, has a reduced oil consumption, and it is possible to transport on a special trolley.
Output
When choosing a threading machine for pipes, the first thing to consider is the scale of production. Depending on the required volumes, a machine model is selected. Both domestic and foreign counterparts are of good quality and are designed for different types of work.
