Model 18S - 18-inch stainless steel precision laboratory slab saw with 4mm 340 stainless steel plate tank, powerfeed, crossfeed vise for specimen fixtures and 1HP 230v 50Hz motor
Many laboratories attempt to use saws intended for the masonry and construction industry to cut test specimens of concrete or asphalt for use in AMPT, TSRST, Hamburg Wheel Tracking, ASTM, Prall and other test protocols.
Unfortunately, saws offered to the masonry and construction industry do not offer the rigidity, stability, automation, and safety most laboratory managers seek. They lack the critical consistency in sample preparation required by laboratory test engineers to perform accurate tests and generate meaningful data.
The costs of sample preparation are high - securing sample material for various locations, baking it, compacting it, coring it, or slicing it and then prepping specimens accurately for testing. Having this large upstream investment in time and money wasted by failures of an inaccurate and unsuitable saw is frustrating to many professional laboratory test engineers.
Unfortunately, saws offered by leading laboratory test equipment providers are extremely expensive, overly complex and are too big to fit in many existing laboratory facilities - walls have to be moved, new doors installed and specialized wiring and other infrastructure upgraded - and should anything go wrong with the machine, an expensive tech has to come in and fix it.
The Highland Park Industrial 18S Laboratory Saw is an automated specimen saw for clamping and sawing accurate geometries for a variety of test protocols. Collaboratively designed with the DOT, it is built out of 4mm 304 stainless steel plate with full stainless and aluminum components. It is simple and rugged in design and function - the same basic design has been used in the lapidary industry for over 30 years for cutting precious and semi-precious gemstones where precision and adherence to tolerances are critical.
The 18S supports a variety of precise clamping fixtures for prepping samples for AMPT, TSRST, Wheel Tracking (Hamburg), ASTM 1 and 3 notch, Prall, Overlay and Semi-Circular Bend tests among others and we have the ability to collaborate on custom designing and manufacturing fixtures for new test protocols. Designed to operate as a water-cooled environment the 18S cutting system is fully contained by the hood that can be easily opened for easy access.
Used by the DOT - Designed in partnership with the DOT to prepare samples for the AMPT and other asphalt and concrete testing protocols with the most stringent of tolerances
Contamination Free - 304 Stainless steel design of all components prevents oxidization and allows usage of water as coolant without damage to the machine
Compact Size and Simple Implementation - Fits through standard doorways and runs on a 20A 110V circuit providing plug-and-play functionality for virtually any laboratory setting
Clean Working Environment - Enclosed hood to eliminate the potential of dust and water becoming air born
Safe Operation - Specimens are cut automatically while the hood is closed eliminating the possibility of operator injury
Precise Geometric Consistency of Samples - Precision clamping mechanisms provides absolute control of specimen tolerances and ensures geometric uniformity of all samples
Many Possible Applications - Suitable for cutting concrete, asphalt, rock, mineral, and gemstones
Sturdy Construction and Easily Maintained - Built to last for years of operation out of 304 stainless steel and aluminum components
Ideal for Specimen Preparation - Supports common sample geometries including:
AMPT cylindrical specimens round cores
TSRST specimens according to EN 12697-46 and AASHTO TP10
Wheel Tracking slabs (Hamburg) or cores according to EN 12697-22 and AASHTO T324
ASTM specimens (1 and 3 notches)
Prall test specimens according to EN 12697-16
Overlay test specimens according to TX-248-F
Semi-Circular Bend test specimens according to EN 12697-44 (except for the notch)
