FAQs

4×8 CNC Router

I want to buy a CNC router for my small-scale household production. Will it be a false move?

Absolutely not! Even though these routers were only available for large enterprises, routers with lower capacity and lower cutting and transit rates are available at a reasonable price to cater to the needs of small and growing production activities.

However, if you’re living in areas where natural conditions don’t favour water-based cooling, an air-cooled spindle is a more reasonable choice. For instance, in the far North where water pipes get frozen in winters, the users find it difficult to operate water-cooled spindles.

Is maintaining a CNC router a herculean task?

Absolutely not! CNC routers are easy to maintain if you keep some general guidelines in mind. Firstly, regular cleaning shall be done and power controls shall be inspected daily. Secondly, vacuum pumps need to be replaced regularly. Thirdly, pumps, bearings and oscillating pumps shall be lubricated regularly and finally, the backlash on every axis shall be adjusted regularly along with regular cleaning of fourth and fifth axis gear assemblies.
