Power options for portable machine tools: which is best for you?

Posted by Alan Hillier on Oct 18, 2017 3:35:00 PM


Portable machine tools such as flange facing machines are used in a variety of different industrial environments and are therefore available in various power options. There’s no single solution ideally suited to all industrial environments, but there will be a best option suited to the environment you intend to work in.

Let’s look at the pros and cons of the three options available: hydraulic, pneumatic and electric.

Regular subscribers to the Portable Performance Blog will know we like to provide insight into how our machines work and describe their applications on-site. Everything we make is designed with machinability in mind, so this time we get back to basics and cover the definition of machinability, what effects it, and how its measured.

The biggest wind turbine contracts awarded in 2016

Posted by Alan Hillier on Dec 15, 2016 11:02:01 AM


If you're a regular reader of the Mirage Machines Portable Performance Blog, no doubt you'll be aware of our orbital milling machines used by wind turbine manufacturers for machining turbine blades and towers. Demand for these products has been very strong during 2016, so we decided to take a look at the biggest turbine supply contracts awarded this year.

Using data from EIC Datastream  (The Energy Industries Council), we've listed the top 20 contracts based on the project value in US$.

In our previous blog post we listed a number of in-situ machining projects relating to power plant maintenance. This time we take a look at one of these in more detail, to and cover the equipment used and the results achieved.

As part of a turbine refurbishment project, Mirage equipment was specified to machine the casing split lines back to the original specification.  A Mirage MR2200 2 axis milling rail was used and mounted onto a Mirage gantry system. Let’s take a look at these in more detail.

On-site machining: power plant project list

Posted by Alan Hillier on Nov 15, 2016 9:03:00 AM



When you consider the demands that turbine components in power plants are exposed to, it comes as no surprise that eventually many components will wear out and operate less efficiently. With steam turbine temperatures being of over 500°C, pressures of 4000psi and components rotating at speeds of over 3000rpm, the importance of a well-managed and robust maintenance programme cannot be overstated.  (Find out more about power plant maintenance strategies on our previous blog post).
