7. MACHINE STRUCTURE
The machine is an electromechanical device. The woodworking machines are powered with
the help of asynchronous electromotor. Rotation from the motor to the knife block (outlet
end of the knife block) and saw blade is performed with the help of multiple vee belt drive.
The belt covers driving pulley and two driven pulleys. The first of the driven pulleys generates
the rotation of the saw blade, and the other one generates the rotation of the knife block and
the end mill cutter. The belt tension is performed automatically as a result of the
electromotor and traction coil weight.
The woodworking machines are equipped with the interlocking devices, which allow
performing only one type of processing: cutting/milling with disc cutter or planning/milling
with end mill cutter.
The machine has a stationary table for cutting and two replaceable tables for planning
(outfeed and loading tables). Planing tables, when used in cutting mode, complement cutting
table.
In the planning mode, the loading and outfeed tables are mounted at the level of slicing
blade cut. Besides, the front table can move down below the level of the slicing blade cut.
That provides the necessary planning depth.
In the cutting mode, the planning tables are mounted at the level of cutting tables, forming a
single-piece area of cutting table. In this case, planning tables cover the rotating cutter block,
ensuring safe operating. Displacing of tables is performed with the help of the in-built lever-
sticks. Such a construction helps to easily and quickly readjust the machine to the necessary
type of processing.
Machine stop has special protection from spontaneous shutdown. It is installed on the
mobile bracket, rotating to ensure accessible switch-on/switch-off of the machine.
The tables serve as a basic supporting surface for a workpiece.
The machine has an angular bump with a ruler and a device for angular cross cutting to
ensure the right location of the workpiece to a cutting tool and the forward, straight,
longitudinal motion.
In order to avoid saw blade jamming during cutting, there is a splitting knife in the machine
construction.
The woodworking machine is equipped with protection devices to prevent access to rotating
parts of the device.
The design includes portable hinged guard to prevent access to the cutter block.
To prevent access to a saw blade /disk cutter, stationary fencing is located below the cutting
table and movable fencing – above.
The design includes end mill fencing to prevent access to end mill/drill.
To prevent access to the end of the rotating cutter block (while the milling device is not
operated) – stationary protection device – end mill fencing.
The machine is equipped with measuring scales, indicating the cutting depth, milling with
disc cutters and planning depth.
