Modular Precision Tool System

Sigma Link, a part of LMW group, has joined with “Kaiser “of Switzerland, to provide the Indian engineering manufacturers world class toolings. These tooling systems are perfectly balanced for maximum rigidity due to high preloading forces and large contact surfaces offering maximum torque transmission for clock or counter clockwise rotation without loss of inter-changeability. Other features include minimal run out due to concentric clampings; assured cutting edge orientation, regardless of the number of components assembled; vibration damping due to friction created between the mating components; and repeatable seating precision with the maximum radial error of 0.002 mm. The product range includes precision micro boring heads to cover range 0.4 to 1180 mm; twin edge rough boring to cover 20 to 1180 mm; carbide boring bars for deep hole boring L/D ratio up to 10 times; coolant adapters; drill chuck holders; Morse taper adapter; collet chucks; milling chucks; universal milling cutter holders; t
