Portable Bandsaw Blade Essentials

Posted by Alan Hillier on Sep 5, 2018 5:09:00 PM

 

What type of blade should be used with a portable band saw? 

When cutting metals with a Mirage portable band saw, an M42 Cobalt bi-metal blade is the way to go. 
Blades if this type incorporate a high speed edge material that’s welded to a fatigue resistant spring backing. These tough blades are capable of cutting carbon steel, tool steel, structural steel, stainless steel, pipes, tubes and mixed metals. Blades supplied as standard with Mirage bandsaws are made from triple tempered M42 cobalt high speed steel with hardened teeth.

Metal Machining Insight: Avoiding built up edge

Posted by Alan Hillier on Aug 29, 2018 9:15:00 AM

What is built up edge?

Built up edge (BUE),  is a problem you can face when machining ‘sticky’ metals such as low carbon steel, stainless steel and aluminium. BUE is material from the work piece that builds up against the rake face of the cutting tool. When this happens the outcome is likely to be a poor surface finish. This is bad news for all machinists - especially for those working in the oil & gas and power generation industries. The last thing you need when you're machining a flange or line boring a turbine casing is to mess up and have to to start all over again.

Understanding how built up edge is formed will help you prevent this from happening. Take a look at the information we've gathered from a variety of sources.

Portable band saw blade speeds for cutting metal pipelines

Posted by Alan Hillier on Aug 20, 2018 12:30:00 PM

 

Portable band saws are designed to be robust and simple to use. If you use them correctly you’ll experience hours of trouble-free cutting with plenty of use from each band saw blade.

With Mirage Portable Band Saws, you get an M42 carbide tipped blade provided as standard. These rugged bi-metal blades feature M42 high speed steel edges - making them ideal to use when cutting difficult to machine solids and heavy walled structures. So if you intend to cut heavy walled pipe and other oil & gas structures these are the blades to use.

The A to Z of nuclear power for on-site machinists

Posted by Alan Hillier on Aug 13, 2018 3:04:30 PM

Getting involved in portable machining projects within the nuclear power sector isn’t normally a quick and simple process. The unique nature of some projects (especially in nuclear decommissioning), the safety risks involved, getting security clearance, and the lengthy tender processes can be off putting to say the least.

But for those who do win the contracts, there’s plenty of familiar opportunities from on-site machining.

Away from the nuclear reactor, the fundamentals are pretty much the same as for fossil fuel power stations. There’s steam turbines to be maintained and plenty of pipe and flange joints to be kept safe and secure. 

So for those of you unfamiliar with the nuclear power sector and thirst for knowledge, we’ve put together an A to Z of the essentials. This is to give you a very basic introduction, so if you want to know more see the websites listed at the end of the article.

World-Class: What does it mean for portable machine tools?

Posted by Alan Hillier on Aug 9, 2018 9:16:00 AM

 

The words ‘world-class’ are so over-used in the business world that they’re now treated with a high degree of scepticism. Many use this phrase without any real thought, hoping it will leave the reader with a warm and fuzzy feeling of reassurance.
For other companies, there’s real substance behind it, backed by a genuine ability to compete with the best in the world
.

At Mirage we make no apologies for describing our portable machine tools as ‘world-class’. We’re proud that our products are regarded as some of the world’s best - and it’s not happened by accident.

So what does it take to be a truly world class business?
