They can also explain how best to organize the operation of equipment to achieve the fastest possible return on investment. In addition, our specialists are ready to install the SF676 milling machine on site and provide training for your employees to operate the machine.
Since 2012, the wide-universal milling unit model SF676 has been produced by the Vyatka Machine Tool Repair Plant, and the first manufacturer of this unit in the 1960s was the Kirov plant "Selmash".
The installation makes it possible to use shaped, disk and cylindrical cutters when operating its horizontal spindle, as well as keyway, end and face cutters when operating a vertical spindle.
The machine provides excellent accuracy for boring and milling operations in production shops that meet generally accepted standards (no strong vibration, no heat sources, humidity at 60–70%, temperature from +18 to +22 °C).
In addition to the above work, the unit allows you to perform a number of other work procedures (chiselling, drilling, boring, counterbore, reaming, reaming, centering, countersinking).
Analogues of the machine are milling equipment from the following plants:
The main advantages of the machine we are considering, as well as all its analogues, include:
All main components and units of the unit ensure its high operational potential. These include:
If you purchase additional tools (various tools, devices for boring and drilling, and so on), the capabilities of the machine expand significantly, and it becomes truly multifunctional.
All key components of the unit are installed on its frame. On its side there are two boxes - feeds and speeds. The spindle head (vertical) is mounted on the front end of the headstock, which moves along horizontal guides (they are located at the top of the frame).
The support moves along vertical guides, and the table moves along horizontal guides. The base plane of the machine is considered vertical. A corner table is connected to it, on which parts are fixed, which the operator processes using a milling unit.
All electrical equipment of the installation is mounted in the frame under protective covers. And at its base there is an electric motor, feed and main movement chains. There is also an electric pump there (it also acts as a container for collecting liquid used to cool the structure during operation).
The vertical spindle, fixed in the head with a trunk, is placed in the sleeve. It is moved manually using a special rack roller. On the faceplate of the trunk, the head can be rotated from a vertical position by ±90°. Two conical pins equipped with handles serve to fix the vertical zero position of the head. It is clamped to the faceplate using bolts (they are very reliable, since their inner surface is hexagonal).
The spindle supports (vertical) are:
The spindle mass is balanced by a leaf helical spring. It is connected to the vertical head (with its body) at one end, and to the rack roller at the other end. Labyrinth seals on the head protect it from contamination and lubricant leakage. At the same time, the vertical head is lubricated daily in accordance with the requirements for maintenance of the unit.
The support moves the main work table horizontally and vertically. Vertical feeding is carried out due to the movement of the caliper along the guides of the bed. They are made in a dovetail format. The caliper body contains a feed control device, which begins to function when the drive shaft receives movement from the feed box. After this, the feed mechanism distributes the rotation to the lead screws (horizontal and vertical).
The feed box provides the spindle head and support with different feeds, and also makes it possible to carry out accelerated movement. Its shafts receive rotation from the gearbox (from its main shaft). Standard feed changes to accelerated feed when the operator presses the corresponding control handle. When he releases it, the machine begins to operate normally again.
The piston pump lubricates the gears of the spindle head and two boxes. This happens according to this scheme:
The worker operating the unit can monitor the described process through a peephole with transparent glass, which is mounted on the feed box (on the flange of this unit) and allows you to control the pulsation of the oil.
Rotation is transmitted to the installation spindle by two gears (one of them is located directly on the spindle). The trunk and vertical head are mounted on guides on top of the spindle head. To support the mandrels, there is a special earring attached to the trunk. In a horizontal spindle, the working device is fastened using a ramrod.
Due to the well-thought-out design of the unit, its operator has the opportunity to carry out very precise coordinate boring operations. The tile and indicator holder is responsible for this process.
According to statistics, the main consumers of the machine are enterprises of the domestic military-industrial complex, which use the machine both in the serial production of parts and in instrumental, experimental, auxiliary, and repair departments; as well as processing industry enterprises primarily for repair and operational purposes.
The SF676 machine allows you to perform various operations: milling flat and shaped planes, drilling, threading, centering, counterbore, boring, chiseling, marking and other types of work. The machine can process parts of the most complex configurations from various materials and with high precision. The machine can use a huge variety of tools and accessories.
Using the SF676 machine, you minimize auxiliary time and process parts economically and efficiently.

Gear boxes and feed boxes are installed on the side of the frame.
In the upper part of the frame, along horizontal guides, a headstock with a horizontal spindle moves. If necessary, attach the head of a vertical spindle to the front end of the headstock.
The support moves along the vertical guides of the frame, and the table moves along the horizontal guides of the support.
A corner horizontal table is attached to the vertical (base) plane of the table, which serves for installation and fastening of the workpieces.
The electric motor driving the main movement chain and the feed chain is placed in the base. The coolant is supplied by an electric pump mounted on a base that doubles as a reservoir.
Electrical equipment is located under covers in the frame.
The gear-type gearbox is assembled in a special housing, which is attached with a flange to the side of the station, and imparts 16 different speeds to the horizontal and vertical spindles by selective dialing.
The speed change is carried out by a switching mechanism located on the front wall of the box body as follows: the gear shift handle (4) must be lifted up. In this case, the disks (6) having a number of holes are separated. When turning the speed dial (1) and the associated disks, the position of the disk holes relative to the fingers (7) changes. This prepares for changing gears.
Moving the shift handle downwards brings the discs back to their original position. At the same time, the fingers, moving, shift the gearbox gears using levers.
When switching, there may be cases where the ends of the teeth of the meshed gears coincide. In this case, the discs do not align. In this case, it is necessary to turn shaft 1 with the flywheel (see Fig. 6).
To avoid gear damage, changing gears under load is prohibited.
The feed box provides the caliper and spindle head with 16 different feeds and rapid movements.
The feedbox shafts receive rotation from 1 gearbox shaft (see Fig. 6). The last (driven) shaft of the gearbox is connected to a roller on which two sprockets (10, 11) are placed (see Fig. 10), transmitting movement to the caliper and spindle head mechanisms.
Changing the feed rate is done in the same way as changing the gearbox (see the description of the gearbox mechanism in the “Speedbox” unit).
When switching feeds, you must ensure that the cross handle of the caliper is in the neutral position.
Accelerated movement is carried out by pressing the handle (7). When the handle is released, the working feed continues.
To ensure a constant direction of rotation of the gearbox gears when the gearbox is reversed, gear (9) is used, which automatically maintains the direction of rotation.
A piston pump (5) is used to lubricate the gears of the gearbox, feedbox and spindle head. The pump piston (4) is driven in reciprocating motion by the eccentric gear (9). When the pump piston moves back and forth, oil is sucked from the frame reservoir and sprayed out. An oil mist is created, which lubricates all gears. To monitor the operation of the pump, a transparent eye (6) is installed on the feed box flange, through which the oil pulsation can be seen.
The support carries the main table (9) of the machine with a vertical working plane and moves it in the vertical and horizontal directions.
The caliper consists of a housing (5) having vertical guides in the form of a “dovetail”
Moving along the guides of the frame, the support carries out vertical feeding of the table. Longitudinal feed is carried out by moving the table along the horizontal guides of the support.
The table feed control mechanism is located in the support body. The control mechanism is driven by the running shaft (4), which receives rotation from the feed box, and transmits rotation to the vertical (3) and horizontal (12) lead screws.
The horizontal spindle (1) is mounted in a special housing (12), which moves along the frame guides, thereby providing transverse feed of the machine.
The spindle receives rotation from the gearbox through the intermediate drum gear (18), (see Fig. 11), mounted in the frame and the gear (9), sitting on the spindle.
The upper guides of the spindle head are designed for attaching the vertical head (Fig. 15) and the trunk (11). An earring (17) is attached to the trunk to support the mandrels. The vertical head, trunk and earring are clamped using crackers when screwing in the screws (10) (see Fig. 5) with an internal hexagon.
The front support of the horizontal spindle is a double-row roller bearing (4) with a tapered bore. Axial loads are taken by thrust ball bearings (5). The middle and rear supports of the horizontal spindle are radial ball bearings (8,10), which simultaneously serve as gear supports (9).
The tool is clamped in the horizontal spindle using a cleaning rod (13).
The amount of mechanical movement of the spindle head is set by intermediate stops (16).
The spindle head is moved by a screw (14) rigidly connected to it and a rotating nut (17) (see Fig. 10) fixed in the frame.
The design of the machine ensures the possibility of precise movements of the headstock for jig boring work. To do this, an indicator holder (18) is installed on the headstock, and a tile holder is attached to the frame, on which tile-parallel measuring tiles are installed.
The vertical spindle is mounted in a special head with a trunk for mounting in the upper guides of the spindle head. The head, if necessary, can be rotated on the faceplate of the trunk (18) ±90° from the vertical. Zero setting in a vertical position is fixed by two conical pins with a handle. The head is clamped to the trunk faceplate using hexagon socket bolts.
The vertical spindle (23) is mounted in a sleeve (5), which is moved manually in the housing (6) using a rack roller (24).
The sleeve is clamped with an asterisk handle (25), which has a hexagon for more reliable clamping.
The weight of the spindle is balanced by a spiral leaf spring, one end of which is connected to the rack platen, the other to the vertical head housing.
The bevel gears of the head are supported by double radial bearings (10.17). Rotation of the spindle shank from the vertical bevel gear (9) is transmitted by splines. The horizontal bevel gear (19) receives rotation through splines from the horizontal shaft (20).
The lower support of the vertical spindle is a double-row roller bearing (3) with a tapered bore.
The upper support of the vertical spindle consists of two angular contact bearings (7), which also absorb axial loads.
The vertical head is lubricated daily using ball grease fittings (8,11). Labyrinth seals (1.13) protect against lubricant leakage and contamination.
The corner horizontal table is a cast iron casting and is attached to the vertical surface of the main table with bolts.
The horizontal plane of the table has three T-shaped grooves.
The vice is attached to the machine for fastening parts and has a 360° rotation in the horizontal plane. The vice can be installed both on a vertical table surface and on a horizontal one, as well as on a round table.
A manually driven round rotary table is designed for installing and securing parts during processing. The table can be installed both on the vertical surface of the main table and on the horizontal surface of the table.
The slotter (3) of the slotting head is mounted in a special housing (5) with a trunk (9) for mounting in the upper guides of the spindle head.
The trunk is interchangeable and serves for installation in a vertical position of both vertical and slotting heads
