Arrangement of components
The main components of the unit are arranged as follows:
- Bed. Cast iron structure covered with a flat cast iron table.
- The table is also a cast iron structure, reinforced with stiffening ribs.
- The carriage is movable, tenon-cut, consisting of a cast-iron plate, a clamp with a ruler, as well as stroke limiters.
The carriage is movably mounted using rolling bearings.
Component mechanisms and units of the unit
The drive of the main movement of the equipment consists of the following parts:
- two-speed motor;
- spindle head connected to the submotor plate;
- V-ribbed transmission.
The spindle head itself consists of a cast iron body in which the spindle itself is mounted on rolling bearings. The spindle attachment has a removable mandrel.

Electrical equipment
The two-speed electric motor is connected to the spindle head by a belt drive. The spindle braking and acceleration time is 2.3 seconds. The engine is equipped with protection against overheating and short circuit. The presence of interlocks in the electrical circuit provides protection to the operator.
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.
