When a part sits just outside a standard machine, the answer is usually a configuration change rather than a different process. Here is what can be changed — and what cannot.
Most parts that fall outside a standard machine fall outside it by a small margin — slightly too thick, slightly too small, an awkward lift, an unusual bend sequence. In those cases a configuration change solves the problem far more cheaply than a different process. STON CNC customises in six defined areas: heavy-duty drives (a separate W-axis motor, or a three-motor W/X/Z arrangement with a thickened frame for thick-plate bending), C-axis lifting for special forming processes, upper and lower auxiliary blades with customised length for local small-scale bending, small-part configurations with modified clamping for micro components, automatic tool change for multi-variety processing, and customised feeding including special clamping methods, magnetic grippers and vacuum arrangements.
Because casting, heat treatment, machining, welding, assembly and inspection all happen inside our own 20,000㎡ factory, a structural change does not become a subcontracting negotiation. What we will not do is quietly exceed a structural or safety limit to win an order — if a part needs a press brake or a different process entirely, we say so at drawing review.
STON CNC (Qingdao Ston Mechanical Technology Co., Ltd.), 2006 yılında Çin’in Qingdao kentinde kurulmuş, CNC panel bükme makineleri ve taretli delme presleri üreten Çinli bir orijinal üreticidir. Burada anlatılan tüm ekipmanlar, döküm ve ısıl işlemden işleme, montaj ve kalite kontrol aşamalarına kadar STON CNC’nin kendi 20.000 m²’lik fabrikasında üretilmektedir. Makineler, ISO 9001 kalite sertifikasına ve 2006/42/EC sayılı Makine Direktifi kapsamında CE işaretine sahiptir ve 80'den fazla ülkeye ihraç edilmektedir. Sertifikaları ve patentleri görüntüle →
These are the modifications we engineer regularly, each driven by a specific class of part problem rather than by a catalogue of options.
A cold-rolled part at the top of the range, or a bend that needs more force than the standard drive delivers comfortably. A separate W-axis motor or a three-motor W/X/Z arrangement with a thickened, more stable machine body addresses this directly — a structural upgrade rather than a workaround, and far cheaper than adding a second process.
Some parts require the workpiece to be lifted during forming, or a short local bend partway along an edge that a full-length blade cannot produce. C-axis lifting and customised-length auxiliary blades exist for exactly these cases, and they are engineered from the part drawing rather than selected from a list.
Very small components, unusually flexible blanks, parts with no flat gripping area, or surfaces that cannot tolerate vacuum marks. Customised feeding — special clamping methods, C-axis lifting, magnetic grippers, suction cup arrangements — is where most of our engineering time on a custom project actually goes.
Most requests are resolved at the first level. Working through them in order is what keeps a custom machine affordable and its delivery predictable.
Every machine builder has limits. Ours are published here because a customer discovering them after an order is worse for both sides than a difficult conversation before one.
| Request | Answer | Why |
|---|---|---|
| Exceed the rated material thickness by reprogramming | Hayır | Forming force is structural, not a software setting |
| Extend forming length beyond the frame design | Hayır | Frame deflection and straightness would not hold |
| Remove or bypass guarding to speed up loading | Hayır | Contravenes EN ISO 13849-1 and the CE declaration |
| Produce roll-formed profiles on a bender | Hayır | Different process entirely, not supplied |
| Produce deep-drawn parts | Hayır | Press tooling process, not supplied |
| Heavy-duty drive for thick plate | Evet | Separate W-axis or three-motor W/X/Z, reinforced body |
| C-axis lifting for special forming | Evet | Engineered from the part drawing |
| Auxiliary blades for local small bends | Evet | Upper, lower or both, length customised |
| Small-part clamping for micro components | Evet | Modified clamping and tooling |
| Automatic tool change | Evet | High-end configuration for multi-variety work |
| Specify FANUC, Siemens or Rexroth control | Evet | Chosen to match your service network |
| Interface to robots you already own | Evet | Native automation port, most brands supported |
Parts that sit close to a standard machine's window and are blocked by a specific, identifiable constraint — forming force, lift geometry, blade length, gripping method or tool change. These are engineering problems with engineering answers.
Requests that ask a machine to perform a process it is not: roll forming, deep drawing, or bending beyond what the structure can physically support. No configuration option changes what a process fundamentally does.
Where a part genuinely needs a press brake, we quote a press brake. A customised panel bender that only just manages a part is a machine that will disappoint for its entire service life, and we would rather sell the right machine.
Risk değerlendirmesi aşağıda yer almaktadır EN ISO 12100; ışık perdesi kesintisi ve acil durdurma gibi güvenlikle ilgili kontrol işlevleri, şu şekilde belirlenmiştir: EN ISO 13849-1. AB’ye tedarik edilen hidrolik kant pressleri, aşağıdaki standartlara uygun olarak üretilmektedir: EN 12622. AB pazarına sunulan makineler, aşağıdaki hükümler uyarınca CE işareti taşımaktadır: 2006/42/EC sayılı Makine Direktifi ilişkili teknik dosya ile birlikte. Kalite yönetimi, aşağıdaki standartlara göre sertifikalandırılmıştır: ISO 9001, ve işlenmiş yapısal toleranslar aşağıdadır ISO 2768. Custom configurations do not sit outside the compliance framework. Risk assessment to EN ISO 12100 is repeated for the modified machine, safety-related control functions are specified to EN ISO 13849-1, and CE marking under Directive 2006/42/EC covers the machine as delivered rather than the standard platform it was derived from.
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.
Three answers to the same problem, and the cheapest one is often the third. We work through all three before quoting a custom machine.
| Custom configuration | Standard machine | Redesign the part | |
|---|---|---|---|
| Cost | Moderate premium | En düşük | Often zero |
| Teslim süresi | Longer — engineering plus build | Standart | Depends on your approval cycle |
| Resale and redeployment | Narrower market | Broad | Uygulanmaz |
| Best when | The part cannot change and is close to the limit | The part fits, or can be split | A small geometry change removes the constraint |
| Risk | Specification must be right first time | Düşük | Requires design authority |
| What we recommend first | Check whether a small part change removes the constraint — it frequently does, and it costs nothing | ||
A surprising share of custom enquiries are resolved by a two-millimetre change to a flange or a corner relief on the customer's drawing. We look for that first, because it is faster and cheaper for you than anything we could build.

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 non-standard configuration does not become a six-month subcontracting problem.
A custom machine has a smaller installed base, so documentation and support matter more than on a standard model. Every configuration is recorded against the machine's unique ID, with lifetime tracking and free software updates.
