More Information

What is Lumsden Grinding?

Lumsden or plough grinding is removing surface material by a grinding process.  The machines have a circular rotating table that rotates the opposite way to the head/grinding stones and removes material to the desired thickness. The benefits of Lumsden/Plough grinding to remove material is the speed and size of the machines compared to conventional Milling machines. We have both in-house and subcontract options covering a range of sizes spanning 100” across corners.

What is Shot blasting and what is it used for?

Shot Blasting is a process to remove rust and any lose surface imperfections from the surface of the steel and any oxidization on the edges of the cut parts. The process forcefully fires small ball bearings of shot at the surface and edges to expose the surface ready for fabricating and painting


In house flattening service by means of a C Frame flattening press to flatten any parts after cutting that have a critical or tight flatness tolerance.

50 Tonne Press                                 Tolerance +/- 2 mm per metre

What is Deburring?

Deburring is the process of dressing the melted dross on the top and bottom of the cut parts along with any oxidization on the edges to make them clean and workable for our customers. Smaller parts are deburred on our Ernst Deburring machine which feeds the parts through on a magnetic table with a top sanding roller which lightly touches the top of the parts to smoot and remove any dross.
