The difference between domestic band sawing machine and circular saw

People who are new to the machinery industry may have some questions. Is domestic band sawing machine and circular saw the same thing? What is the relationship between them?

Generally speaking, the domestic band sawing machine is a kind of sawing machine with circular band saw blade as saw tool, and one-way continuous linear motion around two saw wheels to saw wood. A circular saw is a sawing machine with a saw blade as a sawing tool, which can be used to cut metal and non-metal.

Band saws are widely used in the wood industry and have many models, which can be divided into: large band saw, heavy cutting band saw, joinery band saw; According to the position of the saw wheel, it is divided into vertical band saw, horizontal band saw and inclined band saw. Vertical band saws are divided into right band saw and left band saw. According to the installation method of band saw: fixed and mobile; According to the number of combined sets: ordinary band saw, multi-band saw, etc.

Circular saw generally refers to the metal circular saw machine, is a kind of hydraulic circular saw. The vertical slide moves up and down, the feeding structure is firm, the movement is accurate, and the floating material seat does not damage the surface of the workpiece. Metal circular saws are also called pipe cutters, and general metal circular saws (pipe cutters), as the name suggests, can cut some common metals: copper, iron, aluminum, stainless steel, etc.

The domestic band sawing machine is mainly composed of bed, saw wheel, upper saw wheel lifting and tilting device, band saw blade tensioning device, saw blade guide device, worktable, guide plate, etc.

The bed is welded from cast iron or steel plate. The saw wheel is divided into the upper sawing wheel and the lower sawing wheel; the lower sawing wheel is the driving wheel and the upper sawing wheel is the driven wheel. The weight of the upper saw wheel should be 2.5~5 times lighter than the lower saw wheel.

The domestic band sawing machine electrical control system consists of an electrical box, a control box, a junction box, a travel switch, an electromagnet, etc., which is used to control the rotation of the saw blade, the lifting of the saw beam, the clamping of the workpiece, etc., so as to complete the normal cutting cycle according to a certain working procedure.

The band saw blades matched with domestic band sawing machines mainly include bimetal band saw blades, hard alloy band saw blades and diamond band saw blades. The specific specifications and models of the saw blades should be purchased according to the size of the saw model. Whether the saw blades are domestic saw blades or imported saw blades should be controlled according to the cost of the enterprise and the price they can accept.

The lubrication system of domestic band sawing machine must be refueled according to the lubrication parts of the machine (wire brush shaft, worm gear box, active bearing seat, worm bearing, upper and lower shafts of lifting oil cylinder, clamping screw rod on the sliding surface of movable vise) before starting. The worm wheel and worm in the worm gear box are lubricated by No. 30 oil bath, which is written by the oil plug hole on the upper part of the worm gear box. The box is equipped with an oil mark. When the saw beam is in the lowest position, the oil level should be between the upper and lower limits of the oil mark. After one month of use, the oil should be changed, and the oil should be changed every 3-6 months. The lower part of the worm gear box is provided with an oil drain plug.
