Tool Holders
Description: The quality or the taper is very important when it comes to a taper shank tool holder. Any variation from the specified value will introduce a clearance between the shank and the spindle bore leading to run out at the cutting edges of the tool. This would cause unequal load among the teeth, reduced tool life and poor surface finish on the work surface. In case of morse taper shank holders the torque transmitting capacity of the holder will get reduced leading to slippage. All reputed manufacturers offer tool holders with taper shank tolerance of AT3 class. This level of accuracy cannot be achieved by blue matching. Use of good quality pneumatic gauging equipment only can ensure it. To ensure quality, the manufacturers should have the facility for metallographic tests to detect defects like cracks, voids, inclusions, and to check the chemical composition of the material. Every batch of heat treated parts are needed to be checked for hardness, case depth and micro structure. Seenu Precision Tooling Systems ensures the quality at every stage from raw material to finished product with the help of its well equipped metallurgical laboratory. Quality standards: taper shanks - angular tolerance better than AT3 class (as per ISO 1947 and IS 7615); radial run out - side lock holders - =5µm; ER/RD collet chucks - =5µm; face mill arbors - =5µm; reduction sleeves - =5µm; cylindrical collet chucks - =3µm; and shrink fit holders - =3µm. These tool holders are offered by Seenu Precision.
