CNC Turret Punching and Panel Bending Solution for Filing Cabinet Manufacturing

A filing cabinet manufacturer in South Africa needed to improve production efficiency, punching accuracy, and bending consistency for high-volume cabinet manufacturing. The customer’s products include single-compartment cabinets, multi-compartment cabinets, cabinet door panels, and sheet metal structural parts that require accurate hole punching, clean panel forming, and stable assembly dimensions.

To support the customer’s production upgrade, STON CNC provided an automated sheet metal fabrication solution integrating a Prensa puncionadeira de torre CNC and a Dobradeira CNC de painéis. The production line is used to process door panel holes, lock holes, ventilation holes, cabinet bodies, and cabinet door panels, helping the customer achieve more stable punching, multi-sided bending, and cabinet assembly quality.

Project Background

Filing cabinet production requires repeatable accuracy across large batches. Cabinet side panels, door panels, back panels, drawer parts, lock areas, and ventilation structures must be processed with stable dimensions to ensure smooth assembly and reliable long-term use.

Before upgrading the production process, the customer faced several typical challenges:

• Cabinet panels required multiple bends with consistent angles.
• Door panel holes, lock holes, and ventilation holes needed accurate punching.
• Manual repositioning increased cycle time and cumulative dimensional errors.
• Conventional sheet handling could cause surface scratches.
• Separate punching and bending processes increased labor demand.
• High-volume orders required a more continuous and automated workflow.

STON’s filing cabinet solution is designed to solve exactly these problems: complex multi-bend profiles, surface scratching, low efficiency, and high labor cost in cabinet manufacturing.

STON CNC Solution

STON configured a production workflow combining CNC turret punching and CNC panel bending.

The CNC turret punch press completes hole patterns, notches, ventilation slots, lock holes, mounting holes, and edge profiles on flat sheets in one setup, reducing secondary operations before bending.

After punching, the CNC panel bender automatically completes multi-sided bending for cabinet panels. This helps maintain consistent angles across production batches and reduces the need for repeated manual repositioning.

For filing cabinet manufacturers, this combination is especially suitable for processing:

• Cabinet door panels
• Side panels
• Back panels
• Drawer panels
• Single-compartment cabinet parts
• Multi-compartment cabinet parts
• Lock hole areas
• Ventilation hole panels
• Mounting and connection structures

Production Workflow

1. Sheet Preparation

Raw sheet metal is prepared according to cabinet model, part size, thickness, and production batch requirements.

2. CNC Turret Punching

The turret punch press processes lock holes, door panel holes, ventilation holes, mounting holes, corner notches, and edge profiles on flat sheets.

3. CNC Panel Bending

The punched sheets are transferred to the CNC panel bender for multi-sided bending, flange forming, and cabinet panel shaping.

4. Cabinet Part Assembly

Finished parts are assembled into single-compartment cabinets, multi-compartment cabinets, and filing cabinet door structures.

5. Final Production Flow

The processed parts move to welding, surface treatment, assembly, and final inspection according to the customer’s production process.

Results After Installation

After installing the STON CNC turret punch press and panel bender, the customer achieved a more stable and efficient sheet metal production process.

The upgraded line helped the customer:

• Improve punching accuracy for door holes, lock holes, and ventilation holes.
• Improve multi-sided bending consistency for cabinet panels.
• Reduce manual repositioning during bending.
• Improve cabinet assembly fit and structural strength.
• Support batch production of single-compartment and multi-compartment cabinets.
• Reduce dependence on manual punching and bending operations.
• Crie uma base mais sólida para a fabricação automatizada de arquivos de aço.

Por que esta solução é adequada para a fabricação de arquivos de aço

Os armários de arquivo são estruturas típicas de chapa metálica. Eles exigem puncionamento preciso, ângulos de dobra uniformes, montagem suave dos painéis e repetibilidade estável em grandes volumes de produção.

A dobragem tradicional em prensa dobradeira exige frequentemente o posicionamento manual repetido, o que aumenta o tempo de ciclo e o risco de erro angular acumulado. A dobradeira de painéis CNC da STON permite realizar a dobragem de painéis de armários em vários ângulos com maior consistência, enquanto a puncionadeira de torre executa furos densamente distribuídos, ranhuras e aberturas funcionais antes da dobragem.

Isso torna a solução adequada para fabricantes de arquivos de aço, armários de armazenamento, armários de escritório, gavetas metálicas, armários para ferramentas e outros produtos de fechamento em chapa metálica.

Valor do projeto

Este projeto na África do Sul mostra como a STON CNC ajuda os fabricantes de armários a passar do processamento manual ou semiautomático para um fluxo de trabalho de produção de chapas metálicas automatizado mais estável.

Em vez de fornecer apenas máquinas individuais, a STON concentra-se na lógica completa de produção: precisão da punção, consistência da dobragem, proteção da superfície, redução da mão de obra e eficiência na montagem dos armários.

Para fabricantes de armários para arquivos que planejam aumentar a capacidade de produção, reduzir o trabalho manual e melhorar a consistência das peças, a combinação de máquina de puncionamento de torre CNC + dobradeira de painéis CNC oferece uma solução prática e escalável.
