Frequently Asked Questions

What is the difference between gun drilling and BTA drilling?

Gun drilling is ideal for small diameter deep holes with diameters typically under 20mm, using internal coolant supply. BTA (Boring and Trepanning Association) drilling is used for larger diameters (20mm+) and uses external coolant feed with higher material removal rates.

Can you customize machines based on our requirements?

Yes, we offer full customization services including machine size, load capacity, CNC control system (Siemens, Fanuc, etc.), automation integration, and special tooling setups.

Do you provide installation and training?

Yes, we provide remote and on-site installation support, operator training, and technical documentation in English and other languages upon request.

What industries use your machines?

Our machines are used in aerospace, automotive, mold & die, hydraulics, energy, and stone processing industries requiring high-precision deep hole machining.
