Analogs

The FSSH-1 machine, the abbreviation of which stands for tenon-cutting milling machine, is produced by several Russian enterprises, which, as a rule, add the first letter of the city where the manufacturer is located to the marking in brackets. The presence of the letter A indicates improvements made in the design. Therefore, machine models are produced:

• FSSH-1A – Kurgan Woodworking Machine Plant;

• FSSH-1A(K) – Kirov Machine Tool Plant;

• FSSH-1A(D) – Dnepropetrovsk LLC “Stankostroitel”.

The exception is the F4 machine model, which is considered an outdated version, produced before the FSS-1 model. It differs in the diameter of the tool used for wood processing (up to 150 mm), the number of spindle revolutions (6 - 8 thousand per minute) and the power of the spindle electric motor (5 kW).

FSSH-1A Woodworking milling machine with tenoning carriage. Purpose, scope

The woodworking milling machine FSSH-1A with a movable tenoning carriage model FSSH-1A is designed for performing a variety of milling work on wood with manual feed, cutting simple tenons up to 100 mm deep using a tenoning carriage, curved milling according to a template with manual feed.

A machine without a tenoning carriage is designated FS-1 .

The FSSH-1A milling machine is designed for performing a variety of milling work on wood along guide lines with manual feed (manufacturing linings, floorboards, plinths, platbands, panels and other molded products), cutting simple tenons using a tenoning carriage and curved milling according to a template with manual feed.

Operating principle and design features of the FSSH-1A machine

The FSSH-1A machine is assembled on a one-piece cast vibration-resistant cast iron frame, inside of which a high-speed spindle unit with a lifting mechanism and a drive from a two-speed electric motor is installed.

A cast iron table with a tenoning carriage is installed on the bed. The upper spindle support, cutter guard with adjustable guide rulers and a pipe for chip evacuation are mounted on the table.

The tenoning carriage has a rotating ruler with an eccentric clamp. Additionally, the machine can be equipped with an automatic feeder (automatic feeder), which is easily mounted on the machine table.

In recent years, with the development of cabinet furniture production, in our country milling machines are mainly used for milling curved chipboard edges. Processing is carried out mainly in two ways.

1. The first method: a sanding head with a sanding belt attached to it is installed on the spindle, and the chipboard is simply sanded, i.e. The milling machine turns into a grinding machine.
2. The second method: milling using a special cutter with carbide replaceable inserts.

Moreover, for milling you can only use cutters with replaceable inserts, and this is an indispensable condition, because When processing chipboards, carbide plates become dull quite quickly. The reason for this is the fairly high hardness of chipboard and its heterogeneous structure.

The room where the machine is installed must meet the requirements of class P-II according to the PUE.

The machine can be operated in the temperature range from +10 to +35°C, with an average relative air humidity of no more than 80%, in a non-explosive environment, in the absence of direct exposure to precipitation.

Type of climatic modification and category of machine placement - UHL4.2, category of storage conditions - 2 according to GOST 15150-69.

Requirements for workpieces entering the machine.

Workpieces must meet the requirements of GOST8486-86 and GOST2695-83:

• Wood moisture content should not be more than 15%
• the quality of wood blanks is not lower than grade 1
• the deviation of the base face of the workpieces must be at least 0.15 mm over a length of 1000

Description of structural elements

Appearance

Using this machine model, you can perform a wide range of milling operations for processing wooden workpieces. The supply of materials occurs manually, there is the possibility of cutting tenons. For this purpose, the design has a special tenoning carriage. You can also process curved surfaces using templates.

The design of this model is simple, the kinematic drive diagram is not complicated. The basis of the equipment is a cabinet, inside of which the power plant is located. From it comes a rotational movement to the vertical shaft. The FSSH-1A model has an adjustable table, safety equipment and a set of guides for processing wooden workpieces.

Overview of hardware components:

• bed. This is a molded rigid box required to install the main components. Some modifications of the machine involve manufacturing the frame by welding;
• Desktop. It is mounted in the upper part of the frame and is made from cast iron. The surface of the table is carefully polished, additional stiffening ribs are installed in the lower part;
• drive device. Consists of a two-speed electric motor, which is connected to the spindle headstock by a belt drive;
• spindle head. A working spindle is installed on it using rolling bearings. Its shaft has a tapered hole for a mandrel. The cutter is installed using a differential nut;
• tenoning carriage. It is installed on the edge of the desktop. Its movement relative to the working cutter occurs with the help of rolling bearings. The tenon carriage plate has several mounting holes for mounting additional components.

To remove chips, the design includes a pipe for connection to the exhaust ventilation system. The workpiece fixation system with a measuring ruler contributes to increasing the processing accuracy. It can be used for milling at an angle.

For operational safety, most of the cutter is covered with a steel protective shield. However, it does not affect the functionality of the equipment, since the design has a convenient lighting system for the shield relative to the working tool.

Design and description of the machine components

bed

The bed of the FSSH-1A milling machine is a rigid cast box-shaped structure, covered with a flat cast iron table. Guides for mounting the main movement drive are fixed inside the frame. The electrical equipment of the machine is mounted in the niche of the frame. A welded version of the frame is allowed.

Table

The table is a cast iron reinforced with stiffening ribs. The table is rigidly fixed to the frame.

When working using a template, the lower ramp ring 8 is installed on the table (see Figure 4).

It is possible to use a ramp ring with a collar diameter different from that supplied with the machine.

Drive of the main movement of the milling machine FSSH-1A

The main movement drive consists of:

• two-speed electric motor 18;
• poly V-belt transmission 19;
• spindle head connected to the sub-motor plate by 15 rods 3.

The belt is tensioned with screw 3 (Figure 2).

The spindle head consists of a box-section cast iron body 4, in which a spindle 1 is mounted on rolling bearings. The bearings are preloaded by a set of springs 2.

At the upper end of the spindle shaft 1 there is a conical hole (Morse taper No. 4) for installing a mandrel 11, which is secured with a differential nut 12. The spindle shaft is locked from rotation by a lock 5, which is interlocked with the drive by means of a screw 6 and a switch 7.

The spindle head with an electric motor has a vertical adjustment movement of up to 100 mm through gear 13, 14 and screw gears 16, 17 with fixation in the required position .

The cutting tool is secured to the mandrel using a set of spacer rings 9 using a nut 10.

A very important element of the machine is the spindle attachment (Mandrel). On the FSSH-1A machine, the mandrel is removable. Particular attention is paid to attaching the mandrel to the spindle using a differential nut. Taking into account the different thread pitch on the mandrel and spindle, when fastening with a differential nut, the cones are brought closer together and axially tightened. We recommend not removing the mandrel unless absolutely necessary. Well, if you still decide to remove the mandrel, then you need a special key for this (the machine is not equipped with this key), and do not forget to lock the spindle shaft with a lock. The use of original spacer rings on the mandrel is especially important for the operation of the machine. We strongly recommend using only “original” rings. These rings are made with extreme precision, and the seats (end part) are ground. Using non-factory rings (a typical mistake) usually leads to bending of the mandrel after clamping the cutter nut. This curvature may not be noticeable to the eye, but when rotating even at 3000 rpm, a rather strong beating and vibration occurs. This is a very common mistake.

Movable tenon-cutting carriage for milling machine FSSH-1A

The movable tenoning carriage includes:

• cast iron plate, which is the front of the table;
• clamp with ruler;
• stops limiting the amount of travel of the carriage.

The carriage plate is movable along guides fixed on the machine table;

The movable mount of the carriage is made on rolling bearings. By means of stops, the magnitude of the stroke and its location relative to the machine spindle are set;

The carriage plate has holes for attaching a clamp with a ruler and thrust clamps in various positions.

The engine is equipped with protection against overheating and short circuit. The presence of interlocks in the electrical circuit provides protection to the operator.

Electrical equipment of the FSSH-1A machine

General information

The electrical equipment of the FSSH-1A(K) machine includes a two-speed asynchronous electric motor with a squirrel-cage rotor as a spindle drive.

The electrical equipment of the machine is designed for the following values ​​of alternating current:

• power circuit ~ 380V, 50 Hz
• 110V control circuit
• 22V alarm circuit

Electrical equipment provides the possibility of its operation in fire zones of class P-II in accordance with the classification of the “Rules for the Construction of Electrical Installations” PUE. The electrical equipment of the FSSh-1A(K) machine is presented in the electrical circuit diagram (Figure 7) and the electrical connection diagram (Figure 8). The list of elements for the diagram is given in Table 7.1. Protection of power circuits from short circuit currents is carried out by automatic switch QF, control and signaling circuits by fuses FU1, FU2, FU3, and from long-term overloads of the electric motor by thermal relays KK1 and KK2.

The control panel is equipped with signal lamps and machine drive control buttons.

The operation of the machine is controlled from the buttons SB1 and SB2. Electrical control equipment is located in a niche located directly on the machine itself.

The circuit provides for electrodynamic braking of the M engine after it is turned off (electrodynamic brake). The engine should slow down in no more than 6 seconds. The permissible machine braking frequency is no more than 10 braking times per hour.

The required deceleration rate (speed) is set by the regulator located on block A, separately for each selected rotation speed of the electric motor M.

The operating principle of electrodynamic braking is based on the flow of reverse current through the stator windings of the motor. The flow time is regulated using a time relay. It is necessary to use the time relay correctly; incorrectly setting the braking time can lead to damage to the electric motor. The time relay must be periodically reconfigured depending on the cutting conditions, the tool used (its size), spindle speed, etc. If engine braking is not essential in operation and you can do without it, then it is better to turn off the time relay altogether, eliminating unnecessary work.

The selection of spindle rotation speed is carried out by switch SA, through additional contacts 16, 17, 18 of block A.

The FSSh-1A machine has four spindle rotation speeds: 3000, 4500, 6000, 9000 rpm. The main drive uses a two-speed asynchronous electric motor. The switch sets the first or second rotation speed. When switching, one of two motor winding connection schemes is selected:

• in position I - triangle connection diagram (motor shaft speed 1420 rpm);
• in position II - star connection diagram (motor shaft speed 2820 rpm)

The rotation speed of the milling spindle is also selected by moving the drive belt along two pulley stages:

• First pulley stage - spindle speed 3000, 4500 rpm
• Second pulley stage - spindle speed 6000, 9000 rpm

Putting the FSSh-1A milling machine into operation

Before starting the machine, it is necessary to externally check the quality of installation and the reliability of the grounding circuits. Turn on the QF circuit breaker, and lamp 11 HL1 lights up, indicating that voltage is supplied to the machine circuit.

By pressing the SB2 button (4-5), turn on the rotation of the electric motor M; at the same time, the HL2 lamp lights up, indicating that the cutter rotation drive is turned on. Stopping with braking occurs by pressing button SB1 (3-4).

Blocking

The electrical circuit of the machine provides the following interlocks: the start of the machine is interlocked with the cutting tool guard (SQ1), the spindle lock (SQ2).

Blocking is achieved by introducing contacts SQ1, SQ2 into the power circuit of the KM1 coil.

Zero protection is carried out by block contacts of the magnetic starter KM1 (4-5).

Inability to turn on the M electric motor during braking. This is achieved by introducing a breaking contact into the switching circuit of the KM1 coil - the KM2 starter (12-13).

The circuit provides for interlocking with a workshop exhauster installation.

Grounding

When installed, the machine must be reliably grounded in accordance with applicable rules and regulations. To do this, the contact clamp of the external protective circuit must be connected to the workshop grounding circuit.

ATTENTION: It is forbidden to press the stop button SB1 when initially starting the machine and phasing it if the electric motor has not reached full speed.
