The best results in deep hole drilling need to be capable and reliable. In order to achieve this, the mold manufacturer provides a new double-cut deep hole drill, internal cooling, designed for special challenges for special applications, including substrate, geometry and wafer clearance. As a result, they go far beyond conventional gun training.
Certain processes and factors are particularly important to ensure the high quality of deep hole drilling. Especially in order to provide the necessary ground stability and fracture strength in the process of drilling into solid materials, appropriate substrate is needed. Ditmar Ertel, managing director of the company: “a special geometric structure that guarantees the formation of low chips and the optimal removal of chips, is also very important in deep drilling.” All of these are provided by our new pilot and deep hole drill.”
The tools made by the company are made of carefully selected hard alloy metal. In addition to crushing resistance, this also ensures a good tool life. A special taper ratio and four pieces of land that support and stabilize the drill in the axial direction, ensuring accurate and unvibrating drilling, even in extremely deep places can be extremely low off center.
The pre-geometric shape of the center of 140 points is necessary for the best positioning of the drill and short wafer. Large chip grooves deliver small chips quickly and safely from the depths. Special design features reduce the feeding force and combine high performance paint with tool wear.
Due to high cutting speed and the length of the drill bit, high-performance ultra-fine deep drilling oil filtration system and the right and the drill – behind through the guide hole, need to the company’s deep hole drill successfully used (pilot drill = 0.02 mm diameter greater than their deep hole drill).
The company’s deep hole drill has a diameter of 1 mm to 20 mm and a length of 8 to 30 x D, which can be used for ordering a special bit of 50 x D.
Ditmar Ertel: “made of steel, cast iron and non-ferrous metal materials of deep hole drilling, by the special tool for the processing of high reliability and high amount of chip removal, excellent space hole precision and good surface quality and separate.”
