Hole Drilling – Precision & Multiple Hole Drilling

Many parts require hole drilling process. It is one of the most common and basic machining processes. Each drilled hole usually plays an important role for the part to function and has to be produced exactly according to the specification. When drilling multiple holes in a part, it is important to set proper drilling conditions to maintain stable processing because a single failure in a hole can ruin the entire part.
We, at Top Seiko, quantify drilling load by measuring tool load to develop the most suitable drilling tool and establish the optimal processing conditions.

Deep Hole Drilling

Deep hole drilling requires more attention to details than other machining processes. For successful deep hole drilling, you need to make sure that the drill is kept straight, and that chips are flushed out of the hole.
Since tool geometry directly affects chip control, we design deep hole drilling tools by ourselves and then these tools are produced either in-house or by tool manufactures according to our specifications.

We do not use gun-drilling machines or any kind of specialized equipment used only for deep hole drilling applications, as we do not work with common materials or simply drill deep holes. Instead, we perform deep hole drilling in hard exotic materials with machining centers, CNC lathes and EDM machines. By using these machines, we can perform deep hole drilling and machining other required features in one operation. Take advantage of our efficient & precision deep hole drilling service for ultra-hard materials!
