A filing cabinet body and drawer front can go from flat coil steel to a bent, punched shell in one continuous automated sequence \u2014 uncoiling, leveling, laser cutting, punching, and bending \u2014 without the part being set down and re-picked between stations, which is where most consistency loss happens on manual lines.<\/p>\n

Why Track One Part Through the Line<\/h2>\n

Most equipment pages describe a production line station by station, as if each machine operates in isolation. That’s not how a filing cabinet body actually experiences the line. The same steel strip that gets uncoiled at 8:00 AM is the same blank that gets laser-cut ten minutes later, and the same blank is the panel that gets punched with lock-body holes and vent louvers before it reaches the bending station. Every handoff between those stages is a place where a manual shop introduces variation \u2014 a part set down slightly off-square, a stack that gets reshuffled, an operator who eyeballs an edge instead of measuring it.
\nThis walkthrough follows a single filing cabinet body panel and a drawer front through STON’s coil-fed automated line, stage by stage, and flags where each stage either removes or still depends on a manual checkpoint.<\/p>\n

\"Lasersnijden<\/p>\n

Step 1: Coil Loading and Leveling \u2014 Establishing the Blank<\/h2>\n

The steel coil \u2014 cold-rolled, galvanized, or stainless, in the 1000\u20131500 mm width range this line class handles \u2014 loads onto the uncoiler, which unwinds the strip and feeds it into the leveler in sync with the leveling rollers. The uncoiler and leveler frame are welded structures that go through heat-aging treatment before assembly, which matters here specifically because an unstressed leveler bed is what keeps the leveling accuracy consistent as thousands of feet of strip pass through it, not just at startup.
\nRated leveling accuracy for this line class is \u00b11 mm\/m\u00b2, with diagonal accuracy held to \u22641 mm across a 2000 mm span. Threading speed is 5 m\/min; once threaded, the line runs at an adjustable 0\u201312 m\/min. For a filing cabinet body panel \u2014 typically in the 400\u2013600 mm width range \u2014 this means the strip is flat enough entering the cutting stage that the panel bender downstream isn’t asked to compensate for a wave the leveler should have removed.<\/p>\n

Manual-line comparison: on a shop that hand-feeds pre-cut blanks from a shear, flatness depends on how the blank was stacked and how long it sat under its own weight. A coil-fed leveler removes that variable at the source, before the blank exists as a discrete part.<\/p>\n

Step 2: Laser Cutting \u2014 Cutting the Body and Drawer Blanks in One Nesting Pass<\/h2>\n

Once leveled, the strip feeds directly into the laser cutting head \u2014 fiber laser, 1\u20136 kW depending on the configured line, with 3 kW and 6 kW as the two most commonly specified powers for this material range. For filing cabinet steel (typically 0.5\u20131.5 mm cold-rolled or galvanized), cut quality at this power range should produce burr-free edges without a secondary deburring pass.
\nThis is also where the body panel and the drawer front get nested together on the same sheet. Nesting software lays out both parts \u2014 the larger body panel and the smaller drawer blank \u2014 to minimize scrap on the same strip pass, rather than running them as two separate cutting jobs on two separate material setups.
\nEdge case to plan for: stainless steel filing cabinets (common for lab and medical furniture applications) cap out at 1.5 mm on this coil-fed line, versus 2.0 mm for cold-rolled steel. If your product spec calls for 2 mm stainless \u2014 not common for filing cabinets, but it happens on reinforced fire-rated bodies \u2014 that thickness needs to be confirmed against the specific laser configuration before the line is quoted, not assumed from the cold-rolled figure.<\/p>\n

\"Lasersnijden\"<\/p>\n

Step 3: Turret Punching \u2014 Lock Holes, Vent Louvers, and Hardware Cutouts<\/h2>\n

The cut blank moves to the CNC torentponspers<\/a> for the features a laser alone won’t produce efficiently: louvered vents, embossed ribs for panel stiffness, and forming operations like trimming and rib pressing. On the servo turret configuration, machining accuracy is rated at \u00b10.1 mm, with a maximum turret speed of 40 rpm and a 150 kg load capacity on the worktable \u2014 more load capacity than a single filing cabinet body panel will ever use, but relevant if the line is later shared across heavier enclosure products.
\nAutomatic loading, sheet separation, positioning, unloading, and stacking are unmanned through this stage. That’s the specific claim worth being precise about: it means the punch press’s material handling doesn’t require an operator between cycles, not that the whole line runs with zero human oversight anywhere.<\/p>\n

Where manual shops lose here: hole position on a filing cabinet lock body is unforgiving \u2014 a lock mechanism that’s off by even 0.3 mm can bind. On a manual turret or a hand-fed punch, that tolerance depends on how consistently the operator re-registers the part after the laser-cutting stage. On the integrated line, the part never leaves the automated handling chain between cutting and punching, so the registration reference doesn’t change hands.<\/p>\n

Step 4: Automatic Bending \u2014 Forming the Body and Drawer<\/h2>\n

The punched blank reaches the panel bender last. For filing cabinet body dimensions (commonly in the 1200\u20132000 mm range for full-height bodies, smaller for drawer fronts), the relevant panel bender frame sizes are:<\/p>\n\n\n\n\n\n\n\n
Model<\/th>\nMaximale buigafmeting (mm)<\/th>\nMaximale buighoogte (mm)<\/th>\nMax Thickness at Full Bend<\/th>\nServo-assen<\/th>\n<\/tr>\n<\/thead>\n
B (1400)<\/td>\n1400 \u00d7 1250<\/td>\n170 \/ 300 \/ 400<\/td>\nCR 1.5 mm \/ SS 1.0 mm (welded)<\/td>\n15<\/td>\n<\/tr>\n
B+ (1600)<\/td>\n1600 \u00d7 1250<\/td>\n170 \/ 300 \/ 400<\/td>\nCR 1.5 mm \/ SS 1.0 mm (welded)<\/td>\n15<\/td>\n<\/tr>\n
C (2000)<\/td>\n2000 \u00d7 1500<\/td>\n170 \/ 300 \/ 400<\/td>\nCR 1.5 mm \/ SS 1.0 mm (welded)<\/td>\n15<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n

Cast-body versions of the same frame sizes handle up to CR 2.0 mm \/ SS 1.2 mm at full bend \u2014 a real difference in what the machine can form, not a cosmetic spec, so the welded-vs-cast choice should be made against your heaviest-gauge body panel, not your average one.
\nPublished assembly accuracy for STON equipment is \u00b10.05 mm, per current manufacturer specifications. The bending sequence itself is where a filing cabinet body’s squareness gets decided: the panel bender’s compensation adjustment system lets bending accuracy and angle be corrected at any point along the fold line without physical shims, which is what keeps a four-sided body panel \u2014 folded on two or four edges depending on design \u2014 square enough that the drawer slides in without racking.<\/p>\n

Automatic loading and unloading integration: the paneelbuiger<\/a> retains a docking interface that pairs with robotic arm, gantry, or truss-type loading and unloading systems. For a filing cabinet line running body panels and drawer fronts back to back, this is what keeps the bender fed without an operator physically placing each blank \u2014 the same unmanned-handling principle carried through from the punching stage.<\/p>\n

\u00a0Step 5: Where the Automated Line Stops (and Where a Person Still Has to Step In)<\/h2>\n

The stages above cover uncoiling through bending. What they don’t cover, on a standard filing cabinet body, is corner welding and final assembly \u2014 joining the bent panel’s seams, mounting slides, and attaching hardware. STON’s line documentation lists automated welding as a separate workstation (robot, positioner, tooling fixture, and seam-tracking system) that can be added to a line, but it’s a distinct integration decision, not a default inclusion, and it needs to be scoped against your specific body design before it’s assumed to be part of the quote.<\/p>\n

FAQ<\/h2>\n

\u00a0Can this line run filing cabinet bodies and drawers in the same production batch?<\/h3>\n

Yes \u2014 the laser cutting stage nests both part types on the same coil pass, and both feed through the same punching and bending stations sequentially.<\/p>\n

What steel thickness range does the line handle for filing cabinet bodies?<\/h3>\n

0.5\u20132.0 mm for cold-rolled and galvanized steel; stainless steel is capped at 1.5 mm on the standard coil-fed laser configuration.<\/p>\n

Does the panel bender need a separate operator per cycle?<\/h3>\n

Not when paired with automatic loading and unloading (robotic arm, gantry, or truss). Without that pairing, the bender still requires manual load\/unload between cycles.<\/p>\n

\u00a0What’s the difference between the welded-frame and cast-frame panel bender for this application?<\/h3>\n

The cast-frame version forms up to CR 2.0 mm \/ SS 1.2 mm at full bend versus CR 1.5 mm \/ SS 1.0 mm for the welded frame \u2014 relevant if your heaviest body panel gauge is near the welded frame’s ceiling.<\/p>\n

Is corner welding included in the automated line?<\/h3>\n

No \u2014 welding is a separate workstation that can be integrated but isn’t a default line component. It needs to be scoped against your specific body design.<\/p>\n

\u00a0What positioning accuracy can I expect on lock-body punching?<\/h3>\n

The servo turret punch press is rated at \u00b10.1 mm machining accuracy.<\/p>\n

\u00a0How long does the coil last before a changeover?<\/h3>\n

This line class supports coil weights up to 10T with inner diameters of \u00d8470\u2013630 mm, but actual run length depends on your specific part’s material usage per unit \u2014 this isn’t a figure STON’s published documentation quantifies in cycles-per-coil, so it should be calculated against your part’s blank size.<\/p>\n

Can an existing filing cabinet factory add this line onto current equipment?<\/h3>\n

STON’s line design is customized around the customer’s existing layout, product structure, and process flow rather than sold as a fixed package \u2014 this is scoped case by case.<\/p>\n
