Hole Drilling \u2013 Precision & Multiple Hole Drilling <\/span><\/h2>\n

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. <\/p>\n<\/p><\/div>\n

Alumina, like other advanced ceramics, is very hard and brittle, making some parts impossible or too expensive to produce. Having superior machinability, machinable ceramics can usually be an excellent replacement for Alumina or even other hard materials. Although each machinable ceramic has unique properties, you may find the one that meets your property and cost requirements. There are many successful cases of such material replacements.<\/p>\n
