Oito pe\u00e7as de chapa por corpo: dois pain\u00e9is laterais (1.800 \u00d7 600), painel traseiro (1.800 \u00d7 800), porta (1.800 \u00d7 800), topo e base (800 \u00d7 600 cada) e uma placa de montagem (1.600 \u00d7 700). Uncoiler, leveler and stacker lengths are set by coil weight, leveling accuracy target and buffer sizing, and are issued on the project layout drawing rather than in the standard product tables. The three published machine footprints alone total roughly 15 m of length. Adding coil handling, leveling, inter-station buffers and stacking, 35 to 45 m of total line length is the planning figure to reserve. Confirm against the layout drawing before pouring foundations. This is the section to hand to your process engineer.<\/strong> STON’s line technical parameter table states 1,000\u20131,500 mm; the company product overview states 200\u20131,500 mm. Both figures are reproduced here. Confirm the coil width range for your specific configuration with STON engineering before finalising nesting. \u207d\u00b3\u207e The line parameter table states \u03c6508\u2013630 mm; the product overview states \u00d8470\u2013630 mm. Confirm against your coil supplier’s mandrel specification.<\/p>\n Model designations appear as A \/ A+ \/ B \/ B+ \/ C \/ D \/ D+ in the product tables and as A2 \/ B2 \/ C2 \/ D2 \/ F2 on the official product page. A maximum bending length of 4,100 mm also appears in company overview material against 2,800 mm in the model table, and a \u00b10.01 mm accuracy claim appears against the \u00b10.1 mm\/m dimensional accuracy in the same table. Treat the model table as governing and request written confirmation of series naming, maximum length and accuracy basis on your quotation.<\/p>\n For the 1,800 \u00d7 600 side panel in this example, C (2000) covers the envelope. The welded frame is rated CR 1.5 mm at full bend, which puts a 1.5 mm cabinet panel exactly at the ceiling. Specify the cast frame instead. The margin costs money on the quotation and saves it over five years of tool and angle stability.<\/p>\n Turret punch press, SF Series servo<\/strong><\/p>\n Maximum turret speed 40 rpm; machining accuracy \u00b10.1 mm; maximum load 150 kg; combined power consumption approximately 3\u20135 kW; air 0.55 MPa; 380 V \u00b15%; external dimensions 5,200 \u00d7 5,000\/5,500\/6,500 \u00d7 2,230 mm. Table structure is a brush and omnidirectional steel ball composite, which is the detail that governs scratch rate on pre-painted or brushed stainless cabinet faces. The station that limits a cabinet line is almost never the punch press. It is either the laser or the bender, and which one depends on hole count versus bend count in your specific part family. Assumption: effective cutting speed for 1.5 mm cold-rolled steel at 3 kW falls in the 12\u201320 m\/min band under normal parameters. Using 15 m\/min for planning: 2.53 min of cutting. Add 25% for piercing, rapid traverse and indexing: \u2248 3.2 min per cabinet set. Verify against the cutting-parameter database supplied with the machine, not against this article.<\/p>\n Turret station. Approximately 180 hits per cabinet set for fixing holes, louvers and cutouts. Assumption: 2.5\u20133.5 s per bend cycle including axis repositioning, and 8\u201312 s per part for load and unload with truss or robot handling. That gives 90\u2013126 s of bending plus 64\u201396 s of handling. \u2248 2.6\u20133.7 min per cabinet set. STON’s tables publish 15 servo axes and the 0\u2013180\u00b0 range but not a per-bend cycle figure; request a simulated cycle time against your own DXF files before committing to a throughput number.<\/p>\n Line output<\/strong>. Bottleneck 3.2\u20133.5 min gives 17\u201318 cabinet sets per hour theoretical. At 85% availability, which is the realistic planning figure once you account for coil changes, program changes, nozzle and lens maintenance and tool changes, output is 14\u201315 sets per hour, or 115\u2013120 cabinet bodies per 8-hour shift. A production line is not a machine. Under Machinery Directive 2006\/42\/EC, linked machinery placed on the EU market as a functional unit is treated as an assembly of machinery, which means the line as installed requires its own risk assessment, technical file and Declaration of Conformity \u2014 not simply a folder of CE certificates for individual stations. Regulation (EU) 2023\/1230 now governs new placements.

<\/p>\nUm layout na pr\u00e1tica: gabinete de distribui\u00e7\u00e3o de 1.800 \u00d7 800 \u00d7 600 mm, a\u00e7o CRS de 1,5 mm<\/h2>\n
\nNet blank area comes to about 7.12 m\u00b2 per cabinet. At 11.775 kg\/m\u00b2 for 1.5 mm steel, that is 84 kg of finished material per body.
\nCoil-fed nesting on a 1,500 mm strip lets you run the two 600 mm side panels two-up and the 800 mm panels one-up with the balance recovered by small parts. Working at 88% utilisation, gross consumption is 8.09 m\u00b2, or 95 kg per cabinet. One 10 T coil therefore yields approximately 105 cabinet bodies.
\nCompare that against sheet-fed blanking from 1,250 \u00d7 2,500 sheets, where a mixed cabinet nest realistically lands near 78% utilisation. Gross consumption rises to 9.13 m\u00b2 and 107.5 kg. The difference is 12.2 kg per cabinet, about 11%. At 25,000 cabinets a year, that is 305 tonnes of steel. Nobody in the SERP publishes this number, and it is frequently larger than the labour saving.<\/p>\nLine sequence and published footprints<\/h2>\n

\nWorking height across the coil section is +800 mm, which sets your operator platform and buffer table heights.
\nOne layout decision that gets made too late: whether the laser and the turret sit in series on one flow, or in parallel branches fed from a common buffer. Series is simpler to control and cheaper. Parallel is what you want if your part mix splits into “high hole count, simple outline” and “complex outline, few holes” \u2014 a split that describes most cabinet plants running both bodies and vented doors.<\/p>\n![\"Unidade](\"https:\/\/stoncncmachine.com\/wp-content\/uploads\/2025\/08\/Laser-Cutting-Unit.webp\")

\nThe mechanical JT Series runs 30 rpm turret speed at \u22642 kW combined consumption. Lower energy, lower flexibility.
\nIf your part mix genuinely needs both punching and contour cutting on the same part in one clamping, the SFL punch-laser combined machine handles it: 300\/400 kN (30\/40 T) punching force, “O” type closed frame, X-axis 2,500 mm in one position and up to 5,000 mm with secondary positioning, Y-axis 1,250\/1,500 mm, step pitch 405 times\/minute at 5 mm, and a die layout of 16A, 11B, 3C, 2D including 1B and 1C rotary stations. STON states it occupies approximately 40% less space than a separate punch press plus laser cutter, and removes the handling, re-clamping and re-alignment time between them.<\/p>\n![\"Turret](\"https:\/\/stoncncmachine.com\/wp-content\/uploads\/2026\/07\/17b2b3bbd25872a85c6f06bbbece1952-1024x464.jpg\")
<\/p>\nCycle time: the bottleneck is not where buyers expect<\/strong><\/h2>\n
\nHere is the model for the eight-part cabinet body above. Every assumption is marked.
\nLaser station. Cut path per cabinet set: blank perimeters total approximately 30.2 m; internal features (DIN rail cutouts, fixing holes, cable entries, ventilation) add roughly 12 m; shared edges in coil nesting recover about 4 m. Net \u2248 38 m.<\/p>\n
\nAssumption: 200\u2013300 effective hits\/min including axis moves. That gives 36\u201354 s of punching, plus sheet handling. \u2248 1.2 min per cabinet set. This station has spare capacity in this example. It becomes the bottleneck the moment you add a louvered ventilation door: 800 louvers pushes the same station past 4 minutes.
\nBending station. Approximately 36 bend cycles per cabinet set (four edges with return flanges on the two sides, back and door; single flanges on top, bottom and mounting plate).<\/p>\n\n\n

\nA note on how this differs from what the market publishes. Compared with the European line-builder category, which typically advertises a single headline figure such as seconds per part or products per minute, the number above is deliberately built from station cycles multiplied by an availability factor. A six-second headline figure describes one station running one part under ideal conditions. It is not a line rate, and quoting it back to your board as a capacity plan will cost you credibility when the line commissions.<\/p>\n![\"STON](\"https:\/\/stoncncmachine.com\/wp-content\/uploads\/2026\/05\/ston_machine_800x500.webp\")
