2A622F4 horizontal boring machine with CNC. Passport, diagrams, description, characteristics

Manufacturer of horizontal boring machines 2A622F4 Leningrad Machine Tool Plant named after. Sverdlov, founded in 1868.

Since 1949, it has been a heavy machine tool manufacturing enterprise. Began producing metal-cutting machines of his own design (horizontal boring, jig boring, copy milling, machining center type, etc.

In 1962, the Leningrad Machine Tool Production Association was created on the basis of the plant.

The association has a closed technological cycle, has foundry, procurement, galvanic production, all types of mechanical processing, bench assembly of machines, painting and packaging areas.

In 2003, bankruptcy proceedings were initiated against the company

In 2004, the plant went bankrupt. The trademark was sold to Kirov-Stankomash, LLC

Synonyms: horizontal boring machine, horizontal boring machine, horizontal boring machine.

Boring machines are intended for processing parts in single and serial production. These are widely versatile machines that can be used to perform rough and fine boring of holes, turning of external cylindrical surfaces and the ends of holes, drilling, countersinking and reaming of holes, milling planes, threading and other operations. A wide variety of different types of processing performed on boring machines allows, in some cases, to carry out complete processing of a part without moving it to other machines, which is especially important for heavy mechanical engineering.

A characteristic feature of boring machines is the presence of a horizontal (or vertical) spindle, which makes an axial feed movement. A cutting tool is attached to the spindle - a boring bar with cutters, a drill, a countersink, a milling cutter, a tap, etc. Recently, program-controlled boring machines have begun to be widely used, which reduces the time for machine changeover, increases labor productivity and improves the quality of processing.

Depending on the nature of the operations performed, purpose and design features, boring machines can be divided into universal and specialized. In turn, universal machines are divided into

horizontal boring machines
jig boring
diamond boring machines (finishing boring machines)

For all types of machines, the most significant parameter that determines all the main dimensions of the machine is the diameter of the boring spindle.

The forming movements in boring machines are: spindle rotation and feed movement. The feed is communicated to either the tool or the workpiece, depending on the processing conditions. Auxiliary movements are:

installation movements of the spindle head in the vertical direction
installation movements of the table in the longitudinal and transverse directions
installation movement of the rear rack with a steady rest, movement of a steady rest along the rack, etc.

There are three types of horizontal boring machines:

with fixed front pillar
with front pillar moving in one direction
with front pillar moving in two directions

Boring machines with a spindle diameter of up to 125 mm are manufactured with a fixed front stand and a rotary table moving in the longitudinal and transverse directions.

Heavy duty boring machines with a spindle diameter greater than 125 mm have a front post that moves in one or two directions.

The largest boring machines with a spindle diameter of over 220 mm are manufactured with a front post that moves in the longitudinal and transverse directions and a stationary plate designed for mounting the workpieces.

The most common of horizontal boring machines are the range of machines with a fixed front column.

Horizontal CNC boring machine 2A622F4 Designed to perform a variety of boring, milling and drilling work, including contour milling and tapping.

Roughness of the machined surface of the hole during fine boring with a VK8 cutter installed in a retractable spindle, in SCh15 cast iron, GOST 1412-79; Ra=1.6 µm.

The machine is configured with a fixed stand carrying a vertically movable spindle head with a retractable spindle and a built-in rotary table with longitudinal and transverse (relative to the spindle axis) movement. Separate feed drives allow simultaneous processing along three coordinates and select the most optimal cutting mode, as well as change the feed rate of units during the cutting process.

The moving units are moved using ball screws with preload.

Lubrication of the moving guides and the main drive is automated.

The machine cannot be integrated into an automatic line. Degree of automation - F4 (control in loop mode).

The 2A622 machine is controlled by a numerical control device (CNC). Programmable movements along four axes - X, Y, Z, W. Axis B operates in positioning mode.

There is no loading device and device for transporting chips.

The coolant system consists of a pumping station with a capacity of 200 liters, a device for watering tools and parts, and a coolant collection system.

The machine has a convenient auxiliary manual control system from a remote control.

The processing area is illuminated by a fluorescent lamp built into the spindle head.

There are no harmful secretions.

Compared to previous versions of the machine model 2A622F4, version 04 has the following advantages:

the latest domestic CNC system of the CNC 2C42-65 class was used with a remote control, increased display sizes, and an increased memory capacity of up to 96K, including the volume of non-volatile memory (ROM) of 48K;
all relay automation of the machine is recorded in the CNC ROM, which made it possible to eliminate a large number of relay contact equipment on the machine and thereby increase the reliability and durability of electrical equipment;
the mode of recording a control program while processing a part in manual mode (machine self-learning) eliminated the stage of preliminary preparation of the program and its testing on the machine;
in the program control mode there are additional automatic cycles for milling holes and processing mounting holes for the flange, which simplifies and shortens the process of the control program;
a fault finding diagnostic system with display of the causes of faults on the display increases the maintainability of the machine and sharply reduces the troubleshooting time;
The CNC device allows you to store programs both on punched paper tape and on the magnetic tape of a cassette recorder, which makes it easy to record, re-record and store programs;
The presence of a movable control panel with a display, on which the data necessary for operation is displayed, ensures convenient control of the machine.

Design and operational features of the 2A622F4 machine:

The rotating work table automatically stops at 0, 90, 180, 270 degrees and has high-precision feedback sensors in all coordinates
Telescopic protection and automated lubrication of guides
High-speed automatic hydraulic clamps
Preloaded ball screws
Powered tool clamping

Main components of the 2A622 machine

bed , reinforced with stiffening ribs, is installed on the foundation using mounting shoes, which, when adjusted, align the machine with geometric accuracy. It is the basis for installing and fastening other working units and mechanisms. The frame contains ground and hardened guides, protected by a telescopic casing.

A rotary table with T-slots is used to position the workpiece. It has two linear movements: longitudinal and transverse, and rotation around its own axis by 360 degrees. The feed movement is carried out by separate drives.

The front post is a vertical column that is mounted on the surface of the bed and has sufficient rigidity and resistance to vibration. The spindle head moves along its rolling guides in the vertical direction. The control panel is attached to the front pillar housing through the console.

The spindle headstock includes a complex of interconnected units installed inside and outside the body of the headstock itself. It contains the following mechanisms: spindle assembly, drives of working parts, devices for controlling the movement of the spindle. Some modifications use a faceplate.

The control system consists of a main console, which is used to turn the machine on and off and control the movement of the working parts. The working mechanisms themselves have handles, levers, and switches for setting the appropriate processing modes.

We carry out restoration repairs of the 2A622 machine according to the customer’s individual technical specifications with the specified equipment. If there are no special requirements, then the entire scope of work is carried out in accordance with existing regulations.

In addition to the 2A622 model, we carry out major repairs and modernization of the following machines: 2M614, 2A620, 2A635, 2A636, 2A637, 2A656 and others.
