SPECIALIST SERVICES

“We’ll make it last longer”

VaalMac have developed options for most shaft applications and offers conventional lathe drilling, gun drilling, deep hole drilling, peripheral drilling and also ejector drilling…

 

This is the services we offer:

  1. 1Deep Hole Drilling

    Deep Hole Drilling

    Deep hole drilling works on the same principle as the gun drilling but is preferred for larger diameter holes (19 to 65 mm), requiring a high surface finish and good hole straightness. It is generally applied where the drilling hole depth is ten times the diameter of the shaft.

  2. 2Gun Drilling

    Gun Drilling

    Gun drilling is the preferred method of drilling smaller diameter precision holes up to 19 mm. The process involves the cutting fluid supplied directly through the drill to deliver cooling at the cutting surface after which it removes the chips through a flute/sleeve around the outside of the drill.

  3. 3Ejector Drilling

    Ejector Drilling

    The cutting fluid is again responsible for cooling and also for transporting of chips away from the cutting edge.

  4. 4Mobile Spark Analysis

    Mobile Spark Analysis

    Chemical spark analysis of alloys to identify grade can be performed with our SPECTRO on-site metal analysers we have the portability and mobility to analyse metal at your preferred location.
