Tapping Holder Collet Chuck Shank Telescopic Buffer Overload Torsion Protection BT40‑GT12‑110L

1、0.01mm body accuracy, the concentricity is high, the processing effect is good, the efficiency is improved, and the service life of the tool is prolonged 2、All tool holders contain high‑accuracy ball guide sleeves, reducing wear and have a higher concentricity, which can protect the product from excessively fast feeding and retraction of the product due to tapping, breaking of the tap and deformation under pressure control 3、The inner hole is finely ground to be bright, and it is ground by the self‑developed grinding stone 4、Advanced vacuum quenching furnace, can achieve carbonitriding, improve the hardness of the tool holder and the accuracy of the body 5、Improving tap life, reduce machine tool parameter requirements, improve thread accuracy and surface quality, torsion overload protection function 6、Provide micro‑compensation synchronous tapping, improving processing efficiency, optimization of extrusion taps, higher suitable for processing fine teeth and inch teeth
