Perforated doors, vented side panels and fan-cut top plates — thousands of holes per panel, at rack-grade pitch accuracy, without a scratch on the powder-coat.
A 19-inch rack is not a bending problem. It is a punching problem with bending attached. A single perforated front door can carry several thousand holes at high open area; side panels, top plates and cable managers add thousands more. That volume of holes, in 1.0 to 2.0 mm cold-rolled or galvanised sheet, is what decides the equipment — and it is why the primary machine here is a CNC taret zımba presi, not a panel bender.
A servo turret punch completes perforation, louvring, fan cut-outs, cable entries, embossed ribs and thread preparations in one clamping, using nibbling and multi-tool stations rather than tracing every hole. A CNC panel büküm makinesi then folds the door and panel returns. A pres freni covers brackets and shelves. What no sheet-metal machine produces is the 19-inch mounting upright — that is a roll-formed profile, a different process, and one STON CNC does not supply.

Rack production concentrates almost all of its machining time in a handful of heavily perforated panels. Get those off a laser and onto a turret punch and the whole shop rebalances.
Fiber laser is unbeatable on contours and one-off shapes. On a repeated hole array it pierces every hole individually, and the cycle time scales linearly with hole count. A turret punch nibbles and multi-hits with a single tool, so a heavily perforated door stops being the constraint on the whole line.
Removing 40 to 60 percent of the material out of a 1.5 mm door releases stress, and a warped door will not close on a rack. Punch sequencing, an over-tonnage protected striking system and a brush-and-ball composite table that supports the panel while it moves are what keep the blank flat enough to bend.
19-inch mounting geometry is defined by IEC 60297-3-100 and EIA-310 — a fixed 44.45 mm U pitch with a repeating hole group. Cumulative pitch error across 42U is what makes third-party equipment fail to fit. Positioning repeatability of roughly ±0.01 to 0.02 mm on a double rack-and-pinion drive is what holds it over a long panel.
For rack work, size the turret punch first and the bender second. The punch is where the hours go; the bender is rarely the constraint.
Rack sheet metal sits comfortably inside the forming window. The limit that matters on this page is not thickness — it is that mounting uprights are a roll-formed product and no punch or bender will make them.

Heavily perforated doors and vented panels in 1.0–2.0 mm, plus four-sided folded doors, side panels and plinths. Rack production is one of the strongest cases for pairing a turret punch with a panel bender.
19-inch mounting uprights, frame profiles and C-sections. These are roll-formed products from a different process and a different supplier — a turret punch can pierce a flat strip, but it cannot form the profile.
Shelves, cable arms, mounting brackets, castor plates and low-volume specials. One press brake alongside a punch-and-bend cell covers everything that should not tie up the main machines.

For the finished product, 19-inch rack geometry is defined by IEC 60297-3-100 ve EIA-310, which fix the 44.45 mm U pitch and hole group spacing. Cumulative pitch accuracy over a 42U panel is set on the punch, and it is what determines whether third-party equipment mounts without reaming.
Makinelerde bu, tamamen kapalı arka çitler, tüm çıkıntılı hareketli parçalar üzerinde koruyucu kapaklar, korunan alan ihlal edildiğinde hareketi durduran lazer koruma sistemi, taretli delme preslerinde aşırı tonaj koruması ve panel bükme makinelerinde ızgara-cetvel ofset yük algılama sistemi anlamına gelir.
This is the single most valuable decision in rack production, and the answer is not the same for every panel. Most shops that own both end up sending perforation to the punch and contours to the laser.
| CNC taret zımba presi | Fiber laser cutting | Rulo şekillendirme | |
|---|---|---|---|
| Repeated hole arrays | Fastest — multi-tool and nibbling | Slow — pierces every hole | Uygulanmaz |
| Complex contours and one-offs | Limited to available tooling | Fastest — no tooling needed | Uygulanmaz |
| Forming operations | Louvres, ribs, embossing, thread prep | Cutting only | Profile forming only |
| Tooling cost | Punch and die sets required | None | Roll set per profile, high |
| Edge condition | Slight burr, deburr may be needed | Smooth, burr-free | Cut to length |
| Rack parts it suits | Perforated doors, vented panels, cable managers | Custom cut-outs, prototypes, short runs | Mounting uprights, frame sections |
| Best combination | Punch-laser combined machine does both in one clamping, in roughly 40% less floor space than two separate machines | Separate supplier | |

If your rack range is built on roll-formed uprights with bolted-on panels, the cell above covers the panels — which is where the hole count, the labour and the flatness problems actually are. The upright line stays with your existing supplier and we will say so at drawing review.

Exchange-table fiber laser for custom cut-outs, prototypes and short runs that do not justify tooling. Runs alongside the turret punch rather than replacing it.

Automatic sheet separation, positioning, unloading and stacking. On perforated panels this matters twice over — it removes handling marks and it keeps the punch fed at its actual cycle rate.
Kafes kiriş sistemini görüntüle →Founded in 2006 and headquartered in Qingdao, one hour from major export ports and the airport. Casting, heat treatment, machining, welding, assembly and inspection all happen inside our own 20,000㎡ factory. That is why a configuration change for a perforated door line does not become a six-month subcontracting problem.
Data centre and telecom projects run to fixed installation windows. A stopped turret punch stops every downstream operation in a rack shop, so response time is part of the specification, not an afterthought.
