The deep-hole drilling technology is applied if the highest precision tolerances are in demand. Deep-hole drilling has many advantages to conventional boring and turning technologies. Boring tolerances up to IT10 and surface roughness Rz until 5 µm can be achieved in only one process step. Very low deviation is ensured by a special shape of the drilling tool. By using deep-hole drilling technology even borings with 200 times of the borer diameter can be realized. The cost-effective production of this procedure is given because drilling can be done in solid matter without a centering pilot hole. Defined surface finish can be attained in one sequence of operation. Centered and cubic borings for complex work pieces of round, cubic or cylindrical shapes are processed by using single lip drilling or BTA technologies in our factories.
For deep-hole drilling there is need in many applications. The most important ones are borings of control channels in hydraulic cylinders, cooling channels, heat exchangers, lubrication channels for hydraulic cylinders or relaxation borings for weight reduction.
More information about deep-hole drilling can be found in the german VDI guidelines 3208, 3209 and 3210.
Our spacious machinery environment with more than 40 modern deep-hole drilling machines, turning machines and milling machines qualify us to process aluminum, steel or steel alloys, copper, brass, Inconel, titanium, Inox and plastics.
Through our long-term experience in the area of deep-hole drilling we process rollers, godets, shafts, casings, gear wheels, cylinders, tubes, sleeves, plates, clamping pieces, plunger rods and hydraulic pipes. Since 33 years we drill in single or series production for customers from branches of medicine technology, systems engineering, mechanical engineering, turbine engineering, automotive industry, paper industry, plastic industry, hydraulic industry, shipping industry, petrochemistry and power plant industry, which we can consider as first-grade supplier to our long-term customers.
For our customers from the whole world we like to conduct service tests for deep-hole drilling of special work pieces. Also our service comprises further processing of your work pieces. For this task we work together with certified partner companies in the fields of honing, grinding and tempering as well as functional logistics for ensuring delivery at any time. Discipline and responsibility towards our customers is most important for us and our long-standing experience will guarantee you a competent performance and content customers.
