Hole pattern GTD

The GTD hole pattern system solution consists of a graphite blank with hole pattern and a hardened tool-steel shaft. Thanks to a screw M6 and the two fixing pins, a secure connection is ensured. The shaft may be reused as often as required.

The  electrode blanks are available off-the-shelf in more than 70 variants. This means that we can ensure extremely short delivery times. The optimised use of material leads to considerably reduced costs for you. Thanks to the standardisation in the entire process chain from mechanical engineering and purchasing through to cutting and eroding, you may achieve major cost and time savings.

Sheets are precisely cut to length

 

All sheets supplied are cut using our precise sawing machine, which ensures accurate product dimensions and a high quality surface finish.  As a result, most surfaces do not require any additional milling or grinding. As you would expect, graphite sheets are available in a wide range of sizes, thicknesses and material grades at GTD.

Electrode blanks with hole patterns

Manufacturing electrode blanks with hole patterns for support systems ties up personnel resources and often leads to reduced up-time for in-house cutting machines.In order to save time and reduce costs, GTD manufacture cost-efficient graphite electrodes with pre-fabricated hole patterns. These are compatible with all common support systems such as Erowa, 3R, Hirschmann, REF System or Mecatool. Needless to say, we will always work to your individual requirements and provide an efficient and fully customised solution.
