UK OEMs Sunflow and NCE Switchgear are using the TruPunch 1000 entry-level CNC punching machine from TRUMPF to reduce costs, improve quality and bring greater control over production schedules.

TruPunch 1000

Sunflow is a specialist in the manufacture of bespoke, low-input electric heaters. Until last year, the company was outsourcing punched sheet metal parts for its radiators; however, the quality was not up to its high standards.

The company set about evaluating the market for a suitable CNC punching machine, assessing a number of different models. The ease-of-use of the small-format TRUMPF TruPunch 1000 and the visibility of its tooling system were two key attractions. Sunflow took receipt of its machine in October 2013.

The small-format machine offers a working area of 2,000 x 1,250mm (with a medium format model offering 2,500 x 1,250mm also available) and a maximum sheet thickness of 6.4mm.

Sunflow punches its radiator bodies from 2mm cold rolled mild steel sheet, although some other parts are punched from 0.6mm material. The feet are the thickest components at 4mm. The company believes that, with the help of TruPunch 1000, its quality standards have been surpassed.

 Some radiator parts are punched in batches of around 100, although with a large bespoke element to Sunflow’s production schedule, two-offs are not uncommon. According to Sunflow, rapid set-up is vital — the TruPunch 1000 gives the company speed and flexibility so it can offer truly bespoke products.

NCE Switchgear offers a complete electrical solution, whether it is motor control, instrumentation or distribution. The company was already familiar with the benefits of TruPunch 1000 technology, as it had purchased two such machines around seven years ago. Although both machines are still performing reliably, another manufacturer’s punching machine had reached the end of its life. The TruPunch 1000 was installed in July 2014,

 In addition to punching electrical enclosures and related components, the entry-level TruPunch 1000 machines also allow NCE Switchgear the opportunity to form threads, make extrusions and bend flanges, hence delivering economic complete processing in a single clamping. The investment has allowed compatibility in production with no downtime or requirement to rewrite programs.

 NCE Switchgear said it is extremely content with the performance of its TruPunch 1000 machines, which on a day-to-day basis are loaded with 2mm-thick zintec, although some parts are also made from 2.5mm galvanised steel.

Typically, components are grouped together to ensure the most efficient method of manufacture is delivered for each project. Tight tolerances and high surface finishes are high priorities.

NCE Switchgear has found the TruPunch 1000 machines to be reliable, fast, easy to use and quick to set up.

Remaining profitable today is a challenge and staying competitive in the future requires solutions that can adapt to your every-changing business needs. The technology built into TRUMPF precision machinery gives fabricators the flexibility to increase the efficiency of their high-quality, close-tolerance part production – in small batches or high volume jobs.

TRUMPF ranks among the world's leading manufacturers of production technology and industrial lasers. Technical solutions for its customers have been the company's focus since 1923. In every technology group TRUMPF machines are designed to minimise unit costs and to provide reliability and a rapid return on investment.

All machines are designed to accept flexible and expandable automation. The choices range from simple productivity gains from features such as automatic laser nozzle exchange through to all the elements necessary for full lights out production.

In the field of CO2 and solid state production lasers the TRUMPF product spectrum is now unparalleled and its experience extends from OEM systems to small hand-manipulation processing stations through to large 5-axis machines. It has competence at any level of power from 2W to 20kW.

The production processes for which TRUMPF lasers are designed are numerous and include welding, cutting, drilling, tube processing, surface treatment, additive manufacturing and component marking.

TRUMPF punching is much more than simply making holes. The TruPunch range of machines provides complete part processing – including forming – and virtually eliminates the need for secondary processing. And in its TruMatic series these benefits are combined with laser cutting; the best of both worlds.

The TRUMPF TruBend press brakes use patented technology to ensure that the bending angle is precise, right from the start and can handle small, complex or single components cost efficiently. Completing the main technology groups are the TRUMPF TruTool range of power and pneumatic portable fabrication equipment.

Under the umbrella of TruServices TRUMPF provides a highly comprehensive range of business services to support its customers. This starts with finance – TRUMPF operates its own bank – and includes full software support both at machine and business level. A wide range of predictive maintenance and service packages are also available as is application and product specific training.

With TRUMPF nothing is left to chance. In every aspect of its business, customers can be assured of quality and exceptionally value for money.
