High-performance milling machine 6Р83Ш: purpose, design, technical characteristics

Production history

The Gorky Milling Machine Plant - GZFS - was the first to produce milling machines in the country in 1931. The enterprise was built according to the plan for the industrialization of the country using German projects. In 1936, the plant produced a unique milling unit for processing tubing for the Moscow metro.

The first series of milling machines, the 6B series, was launched in 1937. Cantilever milling machines of the 6P series began to leave the plant’s assembly line in 1972. Among them was the widely-universal model 6Р83Ш with a table of the third row of sizes.

After the merger of several factories, including GZFS, into the industrial group Stanko LLC, in 2003 the company underwent modernization. The production of CNC machines began, created on the basis of previously produced models, including the highly versatile 6Р83Ш.

Vityaz 6Р83Ш Cantilever-milling horizontal machine

“Vityaz” is a Russian brand that is not inferior in quality to its European counterparts. There is a main and pleasant difference - their cost. Magnet-based Vityaz machines have positively proven themselves as reliable and efficient equipment.

Stankoinkom is the official dealer of Vityaz machines in Russia. Our Vityaz product catalog presents most of the equipment from the official Vityaz website.

Under the Vityaz brand, together with the largest German manufacturer, high-quality magnetic drilling machines are produced. They are designed taking into account the shortcomings of machines presented on the Russian market. Vityaz machines are not inferior in quality to their European counterparts, but have a more reasonable price. Equipped with a soft start and overload control system. Cast construction minimizes tool runout. Special motors with increased torque.

The technical characteristics of widely-universal cantilever milling machines allow milling parts of both small and large dimensions. For processing large-sized workpieces, a retractable trunk is provided in which a spindle unit is installed.

The subtleties of do-it-yourself repairs

To determine the scope of repair of the machine, it is checked in idle mode. You should pay attention to the equipment’s execution of commands and switching between different operating modes. The wear of the guides is measured. After this, unit disassembly is carried out. All working elements and parts should be washed and inspected, the scope of repairs should be determined, and a defect list should be drawn up.

1. All guides are scraped; in case of large defects, they are processed on a surface grinder.
2. Sprockets and wheels with broken and heavily worn teeth are replaced with new ones.
3. The spindle bearings are washed, lubricated and adjusted.
4. The adjusting wedges are scraped down and the gap is selected along the guides.

After replacing worn parts, the machine is assembled. The gaps are selected, the parallelism and perpendicularity of the guides are set. Medium repairs involving scraping the guides and replacing gaskets and couplings can be done at home. Replacing bearings and gears is expensive, but affordable for hobbyists.

Important!

The milling machine has a complex electrical circuit. It is better to entrust its inspection and repair to a specialist.

Where to order and buy?

The GZFS enterprise stopped producing milling machines in 2009 and transferred the documentation to the young Stanochny Park LLC. The plant manufactures equipment of older models to order. Organizations involved in major equipment repairs offer machines for 900,000–950,000 rubles. with a guarantee of 6 months.

The old machine made by the Gorky plant is offered by workshops and owners on various trading platforms on the Internet. The asking price is from 400,000 rubles, depending on the condition.

The durable milling machine 6Р83Ш was designed for round-the-clock operation with maximum load. The surviving examples are usually in good condition and, after reconstruction, work for a long time and without failure. The equipment is in demand for work in private workshops for single production of complex parts.
