How portable milling machines work

Posted by Alan Hillier on Sep 14, 2017 1:49:37 PM


Portable milling machines are used widely in the oil & gas and power generation industries. Some typical projects to date that have used Mirage milling machines include pipe seam weld removal, stay vane machining at a hydro plant, and heat exchanger refurbishment.

To help you understand how they are constructed and how they work we've designed a simple infographic to help you understand the basics. The illustration shows the MR2000-A Milling Machine, which is one of several 2 axis portable milling machines available in the Mirage range. 

For a quick snapshot you can view the image below, or for a closer look we recommend you click here to download the illustration in Pdf format.

For full technical specifications of our full range of milling machines we recommend you download our Linear Milling Buyers Guide.

Portable milling machines are used for many different types of on-site machining projects throughout the oil & gas, power generation and petrochemicals industries.

For the on-site machinist, knowing in advance how the product will be mounted onto the job will not only help things run smoothly, but also deliver accurate results, and ultimately, save the customer both time and money.

So, what are the different ways that 2-axis and 3-axis portable milling machines can be set up?

Our examples below will give you an overview of the commonest methods.

Using a keyway cutter for in-situ repairs

Posted by Alan Hillier on Jun 15, 2016 11:00:00 AM



What is a keyway?

A keyway is the slot created in a shaft to accept a ‘key’ that connects a rotating machine element to a shaft. The key prevents relative rotation between the two parts, enabling torque transmission. Commonly used machine components using a keyed shaft include gears, pulleys, couplings, motor pumps and turbines.

The keyway method has been used commonly in the power transmission industry for many years. When used correctly, this method guarantees that virtually no relative motion can take place between a shaft and its respective connected component.
