Metal Cutting Sawing Machine Type Follows Stock Shape

The shape of the metal on the bench decides the kind of saw that should cut it. A short run of round bar, a long steel beam, a stack of pipes and a thick block of alloy each pull the choice of Metal Cutting Sawing Machine in a different direction. Zhejiang Hengsimai Intelligent Machinery Co., Ltd. builds circular sawing machines and several families of band saw, so the match between stock and machine can be made inside one product range.

Circular Saws Cut Fast and Clean

A circular blade turns in one direction against the work and takes small bites at high rate. On bar, tube and light sections the result is a quick cut with a clean face, which cuts down on later machining. The Oblique Push Automatic Metal Circular Cut Saw Machine and the Flat Push Type High Speed Circular Sawing Machine belong to this family.

Repeated production parts suit a circular Metal Cutting Sawing Machine, because the cycle is short and the cut surface needs little finishing. A large solid section is different: blade diameter limits the depth of cut, and the choice moves toward a band saw.

Band Saws Take Size and Variety

A band blade is a long, thin loop of steel running over two wheels. Its narrow kerf wastes less metal, and because the cutting depth depends on the frame rather than on a blade diameter, a band-type Metal Cutting Sawing Machine handles heavier stock. It also copes with a wider spread of materials, from steel to aluminium, copper and alloys, with the blade type and cutting speed changed to suit each.

The band saw range from Hengsimai runs from Semi-Automatic Band Saw Machines and High Speed Band Saw Machines to CNC Band Saw Machines and Vertical Band Saw Machines. The Fully Automatic Horizontal Band Saw Machine for Metal Cutting is made for continuous bar cutting, and the High Speed NC Fully Horizontal Bandsaw Machine adds numerical control to repeat lengths without a person at the vise.

Columns Keep the Blade Straight

A long thin blade bends sideways under load, and that sideways drift shows up as a cut that is out of square or wavy. Rigidity in the frame resists it. The Double Column Horizontal Metal Band Saw Machine and the 650mm Semi-automatic Double Column Band Saw Machine hold the cutting head between two columns, which keeps the head level through the cut and stops it from twisting as the blade bites.

A double column Metal Cutting Sawing Machine suits work where the cut faces must be flat and square from the opening piece to the final one, such as billets cut for forging or bars cut for turning.

Vertical Saws for Big Pieces

Not all metal arrives as bar. Heavy plates, large castings and awkward blocks are easier to bring to a saw that stands upright, with the work lying on a table and the blade running vertically through it. The Vertical Band Saw for Cutting Big Materials suits this case, since the operator can guide the workpiece through the blade instead of lifting it into a vise.

Feeding and Clamping Decide the Cut

Whatever the saw type, the quality of the cut depends on how the stock is held and advanced. A bar that shifts in the vise leaves a stepped face, a feed that is too fast overloads the teeth, and one that is too slow rubs and dulls the edge.

Automatic feeding takes this judgement out of the cut. The High Speed Automatic Feeding Metal Band Saw Machine feeds automatically, and the fully automatic and NC machines go further by moving the stock itself. A Metal Cutting Sawing Machine with automatic feed holds a steady load on the blade, which keeps teeth sharp for longer and gives an even surface across the run.

Setting the Machine to the Material

Steel, aluminium and copper cut in different ways. Steel needs slower blade speed and steady coolant, aluminium needs faster speed and a blade that clears chips, and copper tends to clog teeth unless fluid washes them away. Blade type and cutting speed change with the material, so one Metal Cutting Sawing Machine from Hengsimai can move between metals.

A workshop that begins from its own stock, and not from a catalogue, ends up with the Metal Cutting Sawing Machine that suits it.
