If you are planning to organize the production, which is associated with the processing, cutting and other work with a metal bandsaw useful to you.It provides the possibility to carry out continuous cutting of metal constructions from ferrous and non-ferrous metals, cast iron and stainless steel.They afford even the very cutting carbide - nickel, titanium, steel and high-alloy structural.
tape machines, however, are designed not only for cut
The main advantages of using band saws in comparison with other machines and tools include the following:
- With the band saw can be done a variety of cuts workpieces that have a thickness of up to 400 millimeters.
- Implementation of the most difficult cuts, which can not be achieved with other equipment.
- band saw can be used in curve sawing.
- In operation generated a minimum of waste (shavings and sawdust), and the cut - smooth and clean, and does not require further grinding.
- tape machine takes up little space, and models that are designed for home workshops are easy enough to set them in place without the involvement of a special lifting equipment.
- Low noise blade does not cause discomfort to the operator and others, which is important if the shop is located next to residential houses.
design band saw
Metal Bandsaw for straight and shape cutting is quite a powerful tool.The working body of such acts bandsaw machines, through which he passes and cutting process.Cloth band saw is a closed metal strip that is welded to the ring and is equipped with teeth that cut and carry workpieces.
Saw fixed and moving 2 or 3 large pulleys, rotational motion is provided by an electric motor, the power of which the determining criterion in the selection of band saw blades.The more powerful the motor, the higher the efficiency and productivity of the machine.
more popular in recent years are bandsaw machines, which are installed bimetal blades manufactured at the same time from two different metals.Thanks to such a device bandsaw blade along with stiffness gain flexibility, and this is a key parameter in the quality workpiece.
basis cloth tape acts tough spring steel, which is welded to the wire, made of heavy-duty rigid tool steel.From it to the final stage of adoption milled teeth.The hardness and size of workpiece dimensions depend on the rigidity and teeth.In the band saw, in some cases set a saw with carbide-tipped.
metal-cutting equipment, which has a rotary vise for the price more attractive than machines with a rotary frame, but inconvenient for cutting heavy and long workpieces.Price machines with rotating saw frame higher, but it is more convenient to use, as they allow to quickly change the angle of the cut.
principle of operation of the machine
Typically, band saws are powered by a belt, located between the two flywheels.Belt when the machine is set in motion, and the operator can load the metal cutting.Such tools make accurate cuts, which is achieved by an equivalent distribution of pressure in the process to the material.
Since the motion and pressure of the blade is always sent to the desktop, there is no risk of return and the release in the direction of the master piece.For this reason, operators prefer the circular band saw.
Metal band saw using a standard form of cutting, which is carried out perpendicular to the axis of the machine, or at any angle that does not exceed 60 degrees.Corner cutting is performed by changing the position of the working body - using a rotary blade frame greatly simplifies the cutting of workpieces.
to protect the band saw while working from overheating applied cooling lubricant or a liquid.This is especially true if you are dealing with thick or rigid metallic materials.The lubricant can be used as a water or other liquid viscous material that is continuously supplied to the blade, bathing him.Moreover, through such a protective effect in the air reduces the amount of metal dust.
Band saws for metal can be equipped with special brushes that continually clean the saw blade.This in turn enables to obtain more smooth propyl.Furthermore, the use of brushes increases the lifetime bandsaw.
Types band saws
Band saws can now be purchased at any specialized shop or from the producers themselves.It is advisable before making a purchase to get acquainted with the characteristics and prices of band saws, as well as to learn what are the kinds of band saws.
All band saws are divided into groups in such characteristics: the number of high-speed mode, the volume of production, which is produced per unit of time and angle.Varies and belt width in the machine, with professional equipment will increase when this option.
example, band saws with a ribbon, a width of 13 millimeters, used mainly for domestic purposes.For the production of models designed to have a width of 19 mm blade.Machines by type of control are divided into manual, semi-automatic and automatic.
On some models, provides the opportunity to specify a specific cutting cycle, which will be installed in the flow characteristics of the metal, and automatic shut-off equipment at the end of the cut through the workpiece.
depending on the field of use, there are four types of band saws.Column machines are generic settings that apply to highly specialized large-scale production.Machines Pendulum used mainly in harvesting areas and repair shops.Machines domestic purposes often have a board modification.
Each woodworking band saw their structure is vertical.Plans of this type of band saw has a horizontal working table with stops that are designed for workpieces whole massive frame and the two pulleys - top and bottom, which stretches the saw blade.
In the process, the item is placed in position close to the corners or the rip fence on the table, and then fed to the canvas, holding both hands and moving the stop, as if on rails.
woodworking machines used for curved, oblique and straight cuts and cuts wood at an angle of 45 degrees.Highlights is the speed of the web, allows you to quickly cut soft materials - foam, plastic and wood.
There woodworking band saws three classes.Domestic models are best suited for use at home, because they are small in size and weight machines bench type.They are usually placed on a special table-stand or workbench privorachivaya screws for stability through the holes that there in the ground.
semi-professional equipment for cutting wood is a large floor machines that are designed for cutting material which has a thickness of up to 200 millimeters, and prolonged use.These machines can also be employed handyman, but they are suitable for use in production.
Professional band saws are also outdoor devices that feature high capacity, large size and weight.According to the manual band saw, they are used in the production as able to withstand long-term operation and the process of cutting the bars of a thickness exceeding 300 millimeters.
working with metal tape machines are horizontal.According to the construction equipment is a table-base with the presence of the grip for fixing details where fixed movable frame.There her 2 pulley bar.The material remains stationary during operation.To cut blank frame falls herself.One significant advantage of processing metal products in this manner performs a complete absence of sparks.
Band saw blades are used for oblique and straight cuts of various profiles - round and square tubes, rods, bars, channels and angles.Some models are equipped with rotary jaws, with which you can carry out cuts at an angle of 45 degrees.
power and possibilities of band saws for metal are much higher than wood, so they can handle, except for metal, wood, plastic and graphite.Each equipment for setting band saw has several different web speed.The soft metal, e.g., aluminum, is accepted at the highest processing speed, and the solid high-alloy steels and titanium alloys - at the lowest.
most commonly used two classes of band saws.Household saws are the most simple devices with manual feed for processing plastics and metals such as iron, aluminum, low alloy and non-alloy steel.These units are designed for individual use in the private workshops.
Poluprofissionalnoe equipment is designed to work with different steel, nonferrous metals, nickel and titanium alloys.These saws are semiautomatic: frame itself is lowered by means of a hydraulic system for cutting the workpiece.Aggregates used in industrial and private procurement industries.These machines provide high tool life and quickly pays for itself, so are particularly popular in the bridge building and private enterprises that manufacture metal structures.
Making band saw
To produce band saw at home, you will need the support of sheet metal, frame rails, pins, bushings, screws, bolts, bearings, strap, collar and hood.
In the manufacture of blade is recommended to adhere to these rules:
- Make sketches to the construction, which will help to gather components and spare parts.
- For welding frame made use of closed profiles, the size of which depends on the size of units and parts.
- can take and U-shaped profiles.In this case, the plate, which are welded must short section.
- When using unprepared will make their profiles by flexible metal sheets that do not exceed a thickness that is equal to three millimeters.
- Make the base using steel sheet thickness of 4 mm or two corners.
- weld to the base frame to secure the upper end of its body, which serves to attach the axis of the upper disc.
- With drills in the frame, you can make big holes.
- Desk treat welded sleeves for the axes of the support bracket and the table that was accomplished rugged horizontal fixing table.
- The ball bearings must be the axis for which you want to screw the lower disc.
- top disc must be installed on the ball bearings, which have a large diameter.Be sure to mount the axis by means of brackets, which allows you to change the angle.
- base frame and have wrench bolting, they placed the bearing housing.
- guides fixed in the frame band saw with his own hands.
- casing is attached with screws to the front of the machine.
- as the material for the manufacture of the table is better to choose the PCB.With the help of screws and welding steel strip and attach the saw blade.
- Secure pulley pin or screws.
- lower and upper disks to install the divorce, rather than parallel, to ensure maximum accuracy of cut.
- is mandatory to apply a protective coating.
Now bandsaw is ready to use and can be applied with success in small businesses - service centers and workshops, as well as at home.Such equipment will be able to cope with the processing of metal, wood, plastic and other materials.
