Opening up cracks with a TC burr so that they can be re-welded

Aviation, gas turbine and power generation are industries synonymous with specialised materials, high safety standards and strict protocols, especially with the sensitive materials involved and critical components that require extreme precision of manufacturing, maintenance or repair.

Pferd, manufacturer and supplier of tools for work on surfaces and material cutting, offers high-performance tools that meet the specialist needs of the technicians who face these industries’ high-tech challenges daily. From cutting to grinding, milling, deburring, filing, brushing, polishing, cleaning and creating defined surfaces, the range of tools are suitable for the manufacture, maintenance, repair and overhaul (MRO) tasks of these advanced industries.

“These sectors require specialised tooling to work on the materials that can withstand exceptional amounts of force and stress,” explains Dennis Phillips, National Sales Manager at Pferd South Africa. “Our company possess the necessary expertise to develop and deliver high-performance tools for these niche markets to improve productivity, reduce process costs and achieve maximum efficiency.”

Tough tools for tough jobs

Pferd tools meet the high requirements of these advanced materials and their different machining processes. “We are active in these industries due to our investment in advanced technology that offers the customer a superior product without any reduction in safety, but a reduction in cost due to a quicker resolution of the repair or maintenance”, says Dennis.

Examples of tools used in these specialised industries

Composite filament brushes

Plastic filament brushes, compared with traditional wire brushes offer cool grinding capability and a lack of sparks. Unlike steel, stainless steel and brass wire brushes, composite filament brushes have minimal risk of a piece of filament breaking off and staying behind on componentry, such as sophisticated gearing or rotors, where there is zero tolerance for contamination.

TC burrs

A typical application within the aviation industry for TC burrs is the opening up of cracks on turbine blades before they are re-welded. A wide range of shapes, sizes and cuts of TC burrs is offered for a variety of applications within these industries.

Mounted points

The TOUGH type is specifically designed for use on materials that are difficult to machine. Applications include weld dressing on repair welds and reworking on turbine blades during aircraft maintenance. It offers a good stock removal rate, as well as cool grinding thanks to the abrasive grain mixture that breaks down easily.

Diamond needle files

Advanced engine technology requires high temperature to increase efficiency. This means that the internal temperature would be destructive for the materials used in the manufacture of the engines. Therefore, integrated cooling holes in the blades and vanes circulate cold air.  Diamond needle files, which are extra slim in design and particularly suitable for deep-set and narrow contours, are used to clean these cooling holes.

Customised solutions

Pferd can manufacture quality custom tools for customers who have very specific requirements. “Our Key Account Manager in South Africa, who is dedicated to the aviation and power generation industries, works closely with the Aerospace team at Pferd in Germany, and is available to consult with customers to help find the best tool solution for their applications. A team of application specialists can provide training on the correct use of these specialised tools as well,” Dennis concludes.
