Universal Testing Machine Core Cutting Machine

Core cutting machine is suitable to cut/drill cores of concrete, rocks, stones, tiles or the similar materials.The machine is suitable for core samples of size upto 150 mm diameter with the help of thin walled diamond bits which are at extra cost.The machine has sturdy base with pillar support in which rack and pinion is provided for adjustment in height and penetration assembly.The leveling screws are provided at the base.For gripping the sample in position suitable grips are provided.A suitable diesel engine is fitted in the machine with cooling arrangement with water.The base frame is also fitted with wheels for ease of transportation.Core cutting machine, diesel engine powered has been designed specifically for the purpose of cutting core samples from asphalt, concrete & reinforced structure of roads, airport runways, bridges etc.The machine comprises of two vertical support columns which carry the drill head/ engine assembly accurately with the help of screwed spindles.The machine will be supplied with water tank for coolant to the cutting bit.The core-cutting machine is portable & has towing arrangement with pneumatic wheels for easy movement the loading frame consists of a central cross head and a lower table.Center cross head is adjustable for clearance by means of a geared motor.Compression test is carried out between the central cross head and the lower table whereas tension test is carried out between center and upper cross heads.The units have six pillars for better stability.Sensing of load is through a strain gauge based transducer, while the movement of the lower table is measured by rotary encoder.Operation of the machine is by hydraulic transmission of load from the test specimen to a separately housed load indicator.The system is ideal since it replaces transmission of load through levers and knife edges, which are prone to wear and damage due to shock on rupture of test pieces.Core cutting machines are designed and developed specifically to take out core sample from asphalt, concrete & reinforced structure.These machines are fitted with air - cooled grieves engine and have a capacity of 100mm dia x 200mm depth.Supplied with one diamond core bit 100mm dia & one core barrel 200 mm long.
