High-precision hydraulic expanding mandrels, clamping systems, and custom fixtures engineered for sub-micron accuracy (≤ 0.005mm TIR) on high-speed CNC machines.
True-running hydraulic expansion chucks and gear hobbing fixtures that eliminate vibration, maximize workpiece concentricity, and require zero external power packs.
Operated using high viscous hydro fluid requiring just 1 or 2 set screw turns for uniform expansion and minimal leakage across high L/D ratio workpieces.
Robust collet and hydraulic expanding hobbing, shaving, and shaping fixtures designed to withstand heavy reciprocating cutting forces.
Every mandrel undergoes 0.001mm dial gauge inspection on bench centers before dispatch to guarantee zero-defect workholding for your CNC production line.
Building long-term engineering partnerships across automotive, transmission gear, machine tool, and defense manufacturing sectors.
Aligning with India's manufacturing expansion, Shree Precision develops indigenous sub-micron hydraulic expansion mandrels and chucks — replacing costly imported tooling with superior accuracy, fast delivery, and local engineering support.
The present scenario in mechanical manufacturing industries is that conventional machine tools are being upgraded to high-speed CNC machine tools. CNC machine tools with their higher accuracies and higher rates of production need to utilize precision component location and clamping systems. Our Prime Minister's policy guideline "MAKE IN INDIA" makes it all the more important that in order to compete with international manufacturers, the manufacturing industry should achieve component location and clamping elements of much higher accuracy.
Hydraulic Expansion Mandrels and Chucks are high precision workholding or toolholding devices for true running of workpieces for machining operations or concentricity inspection. In tool holding applications, true running increases tool life by 15% to 20%. The run-out is consistently less than 0.005mm Total Indicator Reading (TIR) in expanded condition. Operated with high viscous hydro fluid, expansion occurs with 1 or 2 turns of a set screw — requiring no external power pack.
ISO 9001:2015 certified manufacturer of high-precision hydraulic expansion mandrels, chucks, and custom gear fixtures in Aurangabad, India.
Founded in 2016, Shree Precision initially specialized in precision cylindrical grinding works. As the mechanical manufacturing industry transitioned to high-speed CNC machine tools, demand for sub-micron component location and clamping elements grew rapidly.
Shree Precision developed indigenous Hydraulic Expanding Mandrels to replace expensive imported tooling. Through rigorous bench-center testing with 0.001mm least count dial gauges, our mandrels consistently achieve 0.005mm total indicator reading (TIR) run-out under repeated clamping and declamping.
