This week, we take a break from the usual technical insight to bring you something different. 2018 marks our 25th year as a manufacturer of portable machine tools, so we’re launching a superb offer to celebrate this important landmark. We also look back at how Mirage has evolved from its humble beginnings back in 1993 to the global company it is today.

This type of gasket is commonly used with flange surface finishes created using Mirage flange facing machines, which is why we decided to put together this simple overview as an introductory guide for the on-site machinist.

2 examples of on-site applications for Mirage Flange Facing Machines

Posted by Alan Hillier on May 10, 2018 4:01:00 PM


Since we started this blog back in 2013 we've covered many different topics, including,  industry news, machine specifications, infographics, machining tips and much more. Wherever possible, we've tried to include bespoke projects and real life applications and these have been well received,

When it comes to flange facing projects, these are usually simple 'quick-fix' tasks, which on their own, haven't warranted the creation of 'in-depth' articles. Our flange facers are so easy to set up and operate, which means there's not a great deal of scope for detailed case studies. So how can we demonstrate they perform to expectations out in the field? 

Here's two very simple real life applications where Mirage Flange Facing Machines were used to repair damaged flanges within a tight timescale.

Lens ring flange joints and how they are machined

Posted by Alan Hillier on Mar 6, 2018 4:03:37 PM


The Lens ring type of flange joint is used to create a seal in high temperature and high pressure piping systems. This joint differs from the standard raised face flange joint (which has a ‘flat’ sealing face), by having a sealing face angled at 20° down towards the centre of the bore. This type of joint is not used on very large flanges, with typical outside diameters of the lens ring gaskets ranging from 20mm up to 385mm.
