- Feed arrangement for cutting
- Cooling water arrangement
This unit is designed for cutting and grinding cylindrical rock specimens upto NX size. The outfit includes 200mm dia diamond impregnated cutter, a fine diamond impregnated grinding wheel a water supply system and sampler holder.
A V-Vice, to hold the sample up to 55mm dia x 140mm long to be cut parallel and square to the longitudinal axis is provided. Cores longer that 140mm can be prepared by reversing the specimen and holding against the vice, A hand feed arrangement is provided to facilitate the specimen with a uniform and smooth feeding motions. This unit is provided with a 3 HP, Three Phase, 440 V A.C. Motor.
Precision Core PreparationThis machine enables accurate and reliable preparation of concrete cores for laboratory testing, accommodating specimens up to 150 mm in length and ranging from 25 mm to 100 mm in diameter. Its robust construction and adjustable vice ensure the stability needed for consistent sample quality, supporting critical research and analysis workflows.
Efficient Wet Grinding SystemEquipped with a water feed system and stainless steel tray, the machine delivers effective wet grinding, which minimizes heat generation and dust during operation. The integrated water tank ensures extended grinding sessions, contributing to cleaner, safer laboratory environments while preserving the integrity of the core specimens.
Enhanced Safety & MobilitySafety features include a protective guard around the rotating blade and low noise emissions (below 80 dB), creating a safer workplace. Caster wheels allow for easy transport inside the laboratory, while the bench-mounted design offers stability during use. Anti-corrosive paint ensures long-lasting performance, even in high-humidity conditions.
FAQ's of Core Cutting Grinding Machine:
Q: How does the water supply and tray system benefit the wet grinding process?
A: The water supply and tray system provide continuous cooling during grinding, reducing heat and suppressing dust formation. This not only enhances the durability of the diamond segment grinding wheel but also preserves the structural integrity of the concrete or stone cores, ensuring more accurate test results.
Q: What core sizes can this machine handle, and how are they adjusted?
A: The machine is supplied with three core drill bits-25 mm, 50 mm, and 75 mm. The adjustable vice allows you to securely mount cores of these diameters, accommodating lengths up to 150 mm. The machine can process a single specimen at a time for precise preparation.
Q: When should the machine be used in a testing workflow?
A: This core cutting grinding machine is used during the sample preparation phase, prior to conducting physical or mechanical tests on concrete, stone, or rock specimens. Use it after extracting core samples from larger structures to ensure flat, parallel ends and accurate dimensions.
Q: Where is the ideal operating environment for this equipment?
A: The machine is designed for use in indoor, dust-free laboratory environments with controlled humidity (up to 85% RH, non-condensing) and temperature (5C to 45C). Its mild steel body with anti-corrosive paint makes it suitable for laboratories across India and similar climate regions.
Q: What are the main safety features of the core cutting grinding machine?
A: Key safety features include a protective guard around the rotating blade and noise emissions below 80 dB to protect users. The manual lever operation provides precise control, while the stability offered by the bench mounting and caster wheels minimizes risk during transport and use.
Q: How does manual operation ensure accuracy in core preparation?
A: Manual controls and the lever-operated mechanism enable fine adjustments to core position, grinding depth, and test stroke (up to 150 mm travel). This direct control allows operators to closely monitor and maintain 1 mm accuracy and 1 mm resolution during sample preparation.
