Elitech EMTI Series Hydraulic Internal Grinding Machine is a versatile, high-precision solution for internal diameter (ID) and face grinding of cylindrical components. Designed with rugged mechanical construction and smooth hydraulic table movement, it ensures consistent performance and excellent surface finish for tool room and small to medium batch production.
Available in three models — EMTI 100, EMTI 200 and EMTI 300 — with maximum clamping lengths from 100mm to 300mm, the machine handles a wide range of component sizes. An optional single-axis NC servo upgrade with HMI is available for customers requiring automated grinding cycles.
– Precision ID Grinding — Accurate and repeatable internal bore grinding of bushings, sleeves, cylinders, rings and more
– Hydraulic Table Movement — Smooth and stable hydraulic operation on grinding slide for consistent feed and high finish quality
– Optional NC Servo Upgrade — Single-axis servo infeed (X-axis) with HMI for programmable auto grinding cycles and repeatability
– Manual or Semi-Automatic — Ideal for tool rooms, small batch production and maintenance applications
– High-Speed Internal Spindle — Up to 18000 RPM grinding spindle for precision small bore applications
– Compact & Rigid Construction — Heavy-duty machine base with vibration-damping design for long-term accuracy
– Tercite-B Guide Ways — Low-friction coated guide ways for all movable slides
– Made in India — Manufactured in Surendranagar, Gujarat since 2002
