Classification of bandsaw machines for metal: classification, operation

Design and technical features of machines

Band saw machine

To perform processing, a band saw is installed in the equipment. It is located on a system of drive shafts that are connected to the electric motor through a gearbox. On the end surface of the saw there are teeth with which the cutting operation is performed.

The large length of the tape ensures a long service life. The cutting unit is usually located at the top of the machine, the direction of the saw is horizontal. The workpiece is mounted on the work table and, with the help of lifting/lowering mechanisms, the cutting part comes into contact with the processing material.

Advantages of using metal bandsaws:

• minimum cutting thickness. This is due to the small thickness of the band saw;
• ability to make cuts at an angle. This requires special models of machines with rotary mechanisms;
• high performance indicator;
• processing of workpieces of various configurations - from pipes to sheet material.

However, despite all the advantages described above, the band saw machine is quite large in size. This is due to the relatively complex mechanism for securing the band saw and its drive.

Most benchtop models do not have a coolant system. However, due to the high processing speed, the surface of the metal becomes very hot, which can lead to its deformation or failure of the saw. Therefore, it is necessary to provide timely cooling for them.

Band saw rating

The choice of construction equipment and tools depends on the tasks that the user sets for him. For domestic use, small-sized desktop models are sufficient. In small workshops, semi-professional equipment is preferred. Powerful productive machines are useful in large production. When compiling the rating, VyborExpert specialists studied the characteristics of models offered on the market, reviews and opinions of professionals, and customer reviews. When comparing products and adding them to the TOP of the best, the following criteria were taken into account:

• Depth and width of cut;
• Power;
• Table size;
• Functional;
• Value for money;
• Availability in stores.

Some masters are interested in additional options. The millimeter scale in combination with several stops will help you process workpiece parts more accurately. Adjusting the speed is necessary when cutting materials of different hardness. This is usually required at a professional level.

Machine for cutting massive products

Like any metalworking equipment, a band saw machine can have a different layout and control system. Therefore, first of all, it is necessary to analyze the operating conditions and, based on the data obtained, select the optimal model.

One of the indicators of the operation of metal processing equipment is the degree of its automation. This is a determining factor when completing large production lines. To perform a cut of complex shape, which a band saw machine can do, an action program is entered into the electronic control unit.

If the cutting operation will be of a single nature, you can choose models for metal with manual control. But even in this case, you should know the main differences between metalworking equipment:

• The location of the saw blade is horizontal or vertical. For metalworking, models of machines with a horizontal saw position are most often made. This is explained by the need to firmly fix the part on the workbench. The vertical position of the saw unit is typical for woodworking equipment;
• machine type. These can be cantilever models for metal, where the saw is lowered onto a fixed workpiece. In single- or double-rack units, the processing unit is shifted in a vertical plane along the racks. To perform complex cuts, it is recommended to use rotary horizontal models.

An important point is the choice of vertical or horizontal saw blade. The actual parameters that the band saw machine has are taken into account - the maximum length of the blade being installed, its width and thickness. You should also choose the right saw material.

For cutting alloyed and unalloyed grades of steel, it is best to use a carbon blade. Heavy cutting conditions are performed using bimetallic models. When processing tool grades of steel, it is recommended to use carbide blades.

Which band saw is better?

The band saw is selected based on the material it will be working with. At home, the noise level of the installation is important. In small workshops, every square meter is needed, so compact models are most in demand. For rare use, it is better to take a simple, inexpensive model and not overpay for bells and whistles and wide functionality.

The following were recognized as the best band saws by the VyborExpert team:

• JWBS-8-M 10000480M from Jet is an inexpensive model for the home or small workshop. It is intended for figured cutting of small wooden parts.
• Proma PP-312 25601312 is a good, reliable saw for small-scale production of wooden products. Adjustable speed and clean surface allow you to work with wood of different species.
• Metabo BAS 318 Precision WNB 619009000 is an easy-to-use machine with well-thought-out workplace lighting, smooth belt running, 2 speeds and table angle adjustment.
• Encore Corvette-35 90350 is the most functional model in the TOP. It is good for straight cutting at different angles or shaped processing of parts of any size.
• Metalmaster BSM-85 17434 is a good device for small-scale production of metal products. It is convenient to adjust the cutting angle and the length of the cut workpiece, and the wheels give the machine mobility.
• Makita 2107FK is a reliable hand-held metal band saw. It can be used independently at home or used with a stand for small-scale production.

To start working with a band saw, it is not enough to simply buy the desired model and bring it to production. You also need to set up the machine itself and select the tape to match the workpiece material. Only in this case will a good result and comfortable work be ensured.

Machine selection options

Vertical band saw model

Having decided which band saw is best suited for specific types of work, you should begin to analyze its technical characteristics. These include dimensions, weight, layout and performance.

First of all, you should pay attention to the power of the power plant of the metal cutting machine. It will determine the maximum cutting speed, as well as the requirements for the workpiece material. Then you need to decide on the type of equipment - desktop or floor-standing, vertical or horizontal type. The former are used for processing relatively small products. If the dimensions of the workpiece are large enough, the choice should be made on floor-standing models.

In addition to these parameters, when choosing a model, you should consider the following technical characteristics:

• the maximum permissible size (depth) of the workpiece being processed. It depends on its cross-section - round, square or rectangular;
• saw blade dimensions;
• metal cutting speed limits;
• the ability to rotate the saw at a certain angle relative to the metal part;
• work table dimensions and workpiece fixation mechanisms;
• the presence of a cooling liquid supply system to the processing area.

Despite the fact that during operation the band saw machine generates a minimum of chips and metal dust, with large production volumes it can get into the components and assemblies of the equipment. To solve this problem, manufacturers provide a system for removing cutting waste.

Some benchtop models have an adjustable end stop. It is designed to set the exact cut length of the workpiece. It is particularly useful in pipe processing where precision is important.

Machine automation levels

Based on the degree of automation, the units are divided into three types.

Manual

The saw frame is lowered by the operator or by its own weight. A hydraulic cylinder with a bypass valve provides adjustment of the speed of movement of the frame, its lifting and fixing. The units are very easy to maintain and operate, they make it possible to cut at an angle.

The operator secures and marks the part. Disadvantages: vibration during operation affects blade wear; it is impossible to control the force of the cutting blade on the part. Such machines are most in demand in small industries.

Semi-automatic

Semi-automatic band saw machine BMSY-820C

The movement of the saw frame, clamping or releasing the workpiece is automated. Cutting occurs at a set speed, at which a special hydraulic cylinder ensures that the required pressure is applied to the part.

Most technological operations operate in automatic mode; the operator is only required to ensure that the material is placed in the clamping mechanism.

Semi-automatic machines come in single-column, double-column or cantilever versions. Used in small-scale production.

Automatic

Type of machines, made in five different versions: single-column, double-column, console, portal and vertical. He completely fixes the workpiece himself; changing the cutting angle and frame movement; turning the table; adjustment of cutting force, pressure on the part, feed speed of the saw frame.

The equipment has the ability, if necessary, to switch from automatic to manual mode of use. They are used in large manufacturing enterprises interested in cutting a huge number of identical workpieces.

The degree of automation significantly affects the functionality of the equipment and its cost.

Other benefits:

• long service life;

• maximum safety (there is a protective casing);

• smooth speed control;

• Possibility of equipping with additional devices (drive or non-drive roller conveyor, hydraulic feed mechanism).

Modern models of band saw machines are equipped with speed sensors that monitor the operating mode of the equipment. The electric motor has overload protection, the blade is cooled with a special lubricant. To increase safety, brushes are used to clean the blade from residual materials, chips and dust. All these measures significantly extend the service life without repairs.
