BTA (Boring and Trepanning Association) is a deep hole drilling technology developed in the 1940s. The method is based on the use of a special hollow tool that supplies coolant under pressure to the cutting zone from outside the drill and effectively removes chips through the internal channel of the tool. This scheme guarantees high accuracy, process stability and high-quality machining of deep holes.
Areas of application:
Mold production: cooling holes, guide holes, holes for guide pillars, forming channels (including for bottles).
Hydraulics: hydraulic cylinders, servo hydraulic cylinders, industrial cylinders, pistons, oil channels in hydraulic valve blocks.
Automotive industry: cylinder heads and blocks of internal combustion engines, crankshafts, steering racks, gear shafts, valve bodies.
Production of shafts and rolls: metallurgical rolls, corrugated shafts for the paper industry.
Fuel and oil systems: nozzle bodies, needle valves, plunger bushings and other precision parts.
Textile machinery: central holes of spindles, eccentric holes.
Medical equipment: processing of titanium alloys, 316 steel, manufacturing of medical rods and bone needles.
Defense industry: launchers, pipe elements, high-speed hydraulic cylinders, specialized parts.
Mining industry: hydraulic cylinders and other units.
Types of processed holes:
through
blind
concentric
eccentric
stepped
Technical features:
high efficiency of chip removal and cooling
stable geometric accuracy at great drilling depth
possibility of integration of automatic loading/unloading systems (optional)
CNC control: Siemens, Fanuc, GSK, as well as PLC solutions
Advantages:
increased productivity
reduced tool wear
stable surface quality
optimization of production processes for serial and mass production
