Hand Operated Machines for HVAC Workshops

Short runs, repairs, round pipe and special fittings still get made by hand. EBR METAL has built guillotine shears and sheet metal bending machines in Konya since 2002, and our manual sheet metal machines for duct shops come in four families that cover that hand work. Every model’s main specifications are listed below, so you can compare before you ask for a quote.

Hand Operated Sheet Metal Machines for Duct Shops

Beading Machine

KT 0.8 / KT 1.2 / KMT 1.2

Manual and motorized beading machines with a cast iron frame, for 0.8 and 1.2 mm sheet. Eight roll sets come as standard (seven on the KT 0.8). The motorized KMT 1.2 has a foot pedal and its own stand. Trimming is available on request.

Manual Guillotine Shear

KMH 1020 / KMH 1270

Hand-lever guillotine shears with a welded steel body, a large table, mechanical sheet clamping and a 0–600 mm manual back gauge. Shearing lengths of 1050 and 1280 mm, up to 1.5 mm sheet.

Manual Folding Machine

CMH 2060 / 2560 / 3060

Manual folding machines with 2060, 2560 and 3060 mm working lengths and a folding angle up to 135°. A slitting attachment is optional.

Slip Roll Machine

MR / SR / MSR

Three-roll machines for rolling sheet into cylinders and curved parts. The MR is a bench-top slip roll, the SR is the manual version on a stand and the MSR is motorized. Useful lengths from 600 to 2050 mm, with wire grooves at the roll ends.

Specifications by Machine Family

Sheet thickness capacities are given for ST37 (S235JR) mild steel, yield strength 235 N/mm² (24 kg/mm²). Galvanized sheet has the same capacity. For stainless steel, plan on roughly half as a rule of thumb.

Manual Folding Machine CMH

Slip Roll Machine MR / SR / MSR

SR (manual, on a stand) and MSR (motorized, 380 V / 3 Ph / 50 Hz) come in the same ten sizes. The model name gives useful length × roll diameter.

Wire grooves on SR and MSR: 4 / 6 / 10 mm.

The MR is the bench-top slip roll, without a stand:

All slip rolls have cast iron main frames and a swing-out top roll (drop-end), so a finished cylinder slides off the end. The SR and MSR rolls are made of SAE 1050 certified steel. Induction-hardened rolls are an option.

How to Choose a Hand Operated Machine

Cutting blanks? The KMH shears cut straight up to 1.5 mm. Pick the KMH 1270 if your blanks are longer than 1050 mm. Use the front set-square for angled cuts and the millimeter scale for square ones.

Folding duct sheet and flashing? Choose the CMH by the longest fold you make. The 3060 folds up to 1.0 mm, the two shorter models up to 1.2 mm.

Rolling round pipe and collars? For light work and short lengths the bench-top MR is enough, though its capacity drops as the length grows, from 1.2 mm at 600 mm to 0.8 mm at 1270 mm. The SR adds a stand and goes up to 2050 mm and 2.0 mm. Rolling many parts a day? The motorized MSR does the same sizes with a brake motor and a foot pedal, so both hands stay free to guide the sheet.

Beading or edging round parts? The KT 0.8 and KT 1.2 are manual and light enough to carry around the workshop. For regular beading work there is the KMT 1.2, on its own stand.

Manual, Bench or Motorized?

Manual machines need no power connection and suit short runs, repairs and one-off fittings. Once the same job repeats all day, a motor saves the operator a lot of effort. Two models in this category have one, the KMT 1.2 beading machine (0.75 kW) and the MSR slip roll (0.75 or 1.5 kW), and both run on 380 V / 3 Ph / 50 Hz. Everything else is fully manual.

What Comes Before and After

Hand operated machines often take the parts that are not worth setting up a line for. Blanks cut on the KMH can be folded on the CMH or rolled into a cylinder on a slip roll. Round pipe with a longitudinal lock seam goes through three steps. The pipe lock edge is rolled on the Pittsburgh Lock Former, the sheet is rolled on a slip roll, and the Pipe Lock Seamer closes the seam. A KT or KMT beading machine then adds beads or edges to the pipe ends.

For machine-made straight cuts from coil, use the Cut-to-Length Line. Stiffening beads across rectangular duct sheet are rolled on the Z Beading Machine. See the full HVAC Duct Production Line.
