Circular Sawing Machines

Circular saw machines for clean cuts in metal

A circular saw machine for metal parts tube, profile and solid bar with a toothed blade at low speed under coolant. The heat leaves with the chip, so the workpiece stays cool and the cut face is square with hardly any burr. The design is widely known as a cold saw, in some workshops as a round saw machine. KNUTH supplies manual circular saw machines in two sizes for small and medium sections.

Circular saw machine, cutting disc saw or bandsaw: the differences

Three machine types part metal, and each leaves a different result:

• Circular saw machine or cold saw: a toothed blade at low speed with coolant. Square face, hardly any burr, no heat colours, little material lost in the kerf. The choice for tube, profile and any visible edge.
• Cutting disc saw, also sold as a circular cutter machine: an abrasive disc, high speed, dry. Low purchase price, paid back in sparks, dust, heat and grinding.
• Bandsaw: a continuous band. At home on heavy sections, long cuts and batch work with automatic feed.

For a workshop cutting tube and profile all day the circular saw is faster and the face needs no dressing. Heavy solid material and repeat batches belong on a bandsaw. The industrial saws category sets out every design.

Manual or semi-automatic: choosing an industrial circular saw

These machines are grouped by how much of the cut they take over. A manual circular saw machine is fed on a hand lever, so the operator hears the cut and changes job without setting up. That suits repairs, single parts and short runs. A semi-automatic industrial circular saw adds hydraulic feed and pneumatic clamping, and it repays the cost once one length is needed in numbers. What KNUTH lists here is manual. Where the cutting runs in series, speak to us and we will check whether a bandsaw with automatic feed is the sounder investment.

Blades and materials

Nothing affects the cut more than the blade. Mild steel and structural work are cut with HSS blades. Stainless steel needs a finer tooth pitch and a slower cutting speed, non-ferrous metals such as aluminium, brass and copper a different tooth geometry again. Thin-walled tube wants many teeth in the cut, solid bar fewer and stronger teeth. Coolant and free chip flow protect blade and face. Matching circular saw blades and further accessories are available from KNUTH.

Applications and industries

• Fabrication and structural steelwork: tube, square and angle for balustrades, gates and frames
• Steel merchants: stock bar and section cut to customer length
• Mining, oil and gas and heavy engineering: pipe and section for repair and shutdown work
• Maintenance departments: a fast, accurate cut when plant is down
• Training and apprentice workshops: simple operation, the mitre cut as a lesson

Cutting capacity and machine sizes

Cutting capacity separates these machines first, meaning the largest section parted at square and on the mitre. Blade diameter, motor rating, cutting speed and fitted equipment follow: coolant pump, length stop and base stand. Both KNUTH sizes swing the head to either side, the angle read on the scale and clamped on the swivel stop. Capacities for the listed sizes appear in the product cards above.

Why KNUTH

KNUTH is an established supplier of machine tools, with a saw programme running from the circular saw through to the bandsaw. The machines are built to European testing standards and the technical documentation goes out on request. You also get straight advice on blades and equipment, at a fair price for the work they do.

Service, spare parts and availability

Local service partners across the region look after the KNUTH range, so support stays near the workshop. Common spare parts come from our central stores, special parts direct from the manufacturers, and a ten-year spare parts availability guarantee applies. Setting up, commissioning and operator instruction we offer as separate services. The detail is on start-up services and on repairs and spare parts.

Other sawing machines from KNUTH

Alongside circular saw machines KNUTH carries bandsaws. Mitre work in heavier sections goes to a horizontal mitre cutting bandsaw, plain cut-off to a horizontal straight cutting bandsaw. Contours and closed cutouts call for a vertical bandsaw.
