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.
Materials compatible with our hole drilling services:
Advanced Ceramics, Fused Silica Glass (Fused Quartz), Glass Ceramics, Borosilicate Glass (Tempax), Silicon, Machinable Ceramics, Metal Ceramic Composite Materials, Molybdenum, Tungsten, and Tantalum.
Hole Drilling Capabilities:
Hole Diameter: micro holes, small-diameter holes, medium and large sized holes
Hole Depth: 0.03~400mm
Hole Shapes: straight, tapered, squared, and tapped holes
Hole Diameter Accuracy:±0.005~0.1mm

Hole Drilling EDM Machine
Wire EDM Machine
*Center-through type coolant system supplies high-pressure coolant to the tool tip through the hole in the spindle and tool for effective chip-flashing, cooling and prolonging tool life.
Drilling tool materials:
tungsten carbide, diamond grains, single-crystal diamond, diamond coating, and compax.
