The category of metalworking equipment includes a machine, the working part of which is a toothed saw blade in the form of a closed tape.
The main functions and capabilities of the band saw machine:
- It is used for processing materials with high hardness values;
- performs straight and curly cutting, provides adjustment of the cutting angle;
- provides a small cutting width, high-quality cutting surface;
- it is designed to work with workpieces of various sizes and geometries, batch processing;
- allows you to quickly change the tape for processing materials with different physical characteristics;
- it is reliable and easy to maintain.
- the bed;
- billet feeding system;
- electric motor and its mechanisms;
- the working part;
- the control system.
Metal cutting is ensured by uniform pressure of the pointed cutting part of the saw blade, which makes a translational movement.
In the process of operation, cooling lubricants (coolants) are used - they prevent overheating of the tape and remove chips from the cutting line.
The length of the band saw depends on the machine configuration.
Its type is selected in accordance with the parameters of the processed material.
Band saws vary:
- by composition (carbonaceous, bimetallic, carbide, with carbide coating);
- characteristics of the teeth (number, shape, type of wiring).
Types of band-cutting equipment
Depending on the metalworking tasks, band saws are used:- Single-column.
The saw frame moves horizontally along the vertical rack, the workpiece is fixed motionless.
To change the cutting angle, rotate the frame itself.
- Double-column.
The saw frame moves horizontally, supported by two racks.
The cutting angle is changed by tilting the desktop with the fixed workpiece.
They are characterized by higher accuracy of work.
- Vertical gantries (for processing large workpieces).
The stationary work table is equipped with guides along which the saw frame moves.
- Pendulum (cantilever).
The workpiece is raised and lowered by a hinge mechanism.
They can be equipped with a turntable.
They are suitable for cutting metal profiles and rolled products.
- Vertical.
The frame moves along the work surface, can be positioned perpendicular to it or at a given angle.
The equipment is suitable for cutting solid workpieces, corners, pipes.
The principle of management
The choice of band sawing devices is influenced by its purpose and production volumes.According to the principle of management, they differ:
- Cutting machines with manual control.
They are suitable for one-time work, small-scale production.
- Semi-automatic machines.
They are characterized by a higher processing speed due to automation of the main processes.
- Automatic devices.
They are characterized by high productivity and are designed for serial production at large enterprises.
