Specimen Grinding Machine Manufacturer,Supplier and Exporter in India
Product Code : TVT-CTE-10515
The Specimen Grinding Machine flat-polishes both ends of cut concrete/core specimens to a high accuracy using twin Ø200mm diamond grinding wheels on two power heads, as an alternative to sulfur-mortar or gypsum capping before compression testing.
How It Works
The specimen is mounted on a workbench that reciprocates automatically during grinding, while the two grinding heads work both ends of the specimen in parallel at the same time. The grinding head can advance automatically (at an adjustable feed rate) or manually, and all parts that contact water are made from stainless steel to resist rust and corrosion; tap water cooling is standard, with liquid nitrogen cooling available if specified at time of order.

Applications
Used to prepare flat, parallel specimen ends after cutting, as an accepted alternative to capping compounds prior to compression testing, consistent with the specimen end-preparation requirements of ASTM C39/ASTM C42 and IS 516 (Part 1/Sec 1 and Part 4).

Frequently Asked Questions
Why grind specimen ends instead of capping them?
Grinding produces flat, parallel, high-accuracy specimen ends directly, which some standards and labs accept as an alternative to applying a sulfur-mortar or gypsum capping compound before compression testing.
What specimen sizes can this machine handle?
Square specimens from 40x40x40mm up to 150x150mm, and cylindrical specimens from Ø50mm up to Ø150mm.
Can this machine grind both ends of a specimen at once?
Yes — the twin power-head design grinds both ends of the specimen in parallel, at the same time, with automatic or manual feed control.
