Trima Triebeser Maschinenbau, a manufacturer of bespoke CNC machining centres for machining wood, plastic and metals, is using special energy chains supplied by Igus to ensure that an extraction hose being used as part of a foundry pattern-making project is guided safely and cleanly.

The company’s machining centres are used for the production of windows, staircases, interiors, doors, furniture, arc work, engravings and toys. One of Trima’s main focuses is on the development of machines for model and mould making that are mainly used for applications with high-precision workpiece processing in individual and series production.

Trima has developed a five-axis machine with a cardan head for the foundry pattern-making project. The system — which has been tailor made for limited workspace — reaches every corner of the workpiece without any collisions.

The application uses a large-volume, 6m-long, 0.3m-diameter extraction hose, which is enclosed in an ‘extender crossbar’ version of Igus’s E4/light series energy chain. A total of four energy chains are used in the machining centre: an E4.1 universal chain for the X axis; an E2/000 series chain and an E4/light clamp version for the Y axis; and an E2/000 energy chain for the Z axis.

Key benefits of product application

  • The E4/light energy chain ensures that the large-diameter extraction hose is guided gently and safely; clamps are mounted directly on the sides and are said to guarantee optimum hose and cable guidance.
  • The rigid crossbars ensure safe guidance over the whole travel distance, even under heavy loads, without additional design elements being required.
  • The safe guidance of the exhaust hose inside the energy chain means constant extraction is possible in every travel position.
  • The machine table can also be accessed from above, which means a crane can be used for loading and unloading.
  • The light version of the E4 energy chain provides a weight advantage; the sides and crossbars are extremely sturdy but slimmer than the standard version, which means there is more space inside and costs are reduced.

Igus

Igus is the largest producer of reinforced plastic energy chains and injection-moulded polymer bearings. The range of polymer bearings includes Iglidur plain, Igubal spherical and Drylin linear bearings. They offer an excellent price-to-life relationship and are developed under the toughest conditions. They are oil, maintenance and lubrication free, low wear, resistant to dirt and dust, corrosion free and simple to fit. Igus also has the data to precisely predict the lifetime of these bearings within a specific application.

Energy chains are the umbilical cord of modern machines. They minimise downtime and protect, support and extend the service life of cables and hoses. The broad range incorporates more than 30,000 innovative, low-cost products. From the smallest ‘micro’ chain to the largest chain in the world, the E4.350, Igus energy chains are capable of long and short travel distances at high speeds in all axes.

Igus also has its own cable series, Chainflex, specially designed with energy chains in mind. They are highly flexible cables, offering a long service life and very small bending radii. A wide range is available, from small signal cables to large power cables, high-speed data cables and glass fibre-optic cables.

The company’s energy chains and Chainlflex cables can be delivered as a fully harnessed and pre-assembled Readychain system, cutting purchasing, warehousing and installation costs.
