To ensure smooth, dependable motion of the cutting head and carriage in its latest XYZ router, Routout CNC, a specialist manufacturer of routers for woodworking applications, has chosen to base the machine’s design on the use of bearings and linear guides from Igus.

Linear actuators and sliding bearings

In the Routout application, the bearings are used to support the router cutting head and the carriage, allowing the cutting head to move rapidly, smoothly and accurately along the X, Y and Z axes.

Eliminating lubrication is a crucial benefit in the Routout application since oils and greases tend to combine with the fine wood dust produced by the routing process to create a sticky grinding paste that is hard to remove and quickly impairs machine performance.

In contrast, as the Igus bearings and guides are designed to operate dry, without the use of lubricants, their performance is completely unaffected by the presence of the dust.

Further benefits are that the lubricant-free bearings and guide require no maintenance and that the possibility of the workpiece being contaminated by oil or grease is eliminated.

Key benefits of product application

  • The actuators and bearings require no maintenance or lubrication.
  • Bearings allow the cutting head to move rapidly, smoothly and accurately, and their operation is unaffected by the presence of dust.
  • The linear guide system uses polymer sliding bearings that run on a hard anodised aluminium rail, giving a low-friction and wear-resistant linear slide.
  • Michael Gaylor of Routout CNC said: ‘We found that conventional bearings and slides were very rapidly affected by the dust that is inevitably produced during routing. Since we switched to Igus bearings and slides, these problems have been entirely eliminated.’

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.
