This method also facilitates, when desired, grinding the glass slides to uniform thickness for the highest quality thin sections. Vacuum is supplied by a high efficiency diaphram type vacuum pump included as standard equipment. Coolant is delivered to the cutting area by a built-in recirculating pump included as standard equipment. The coolant supply is contained in a pull-out stainless steel coolant tray. The tray is easily removed for disposal of spent coolant an sediment.
Provision is built-in for using tap water for ultimate cooling efficiency and purity.
The feed-rate is set by a dial that electronically controls the variable speed drive to the vacuum chuck. An adjustable slip clutch maintains constant, even cutting pressure on the working surface of the diamond blade or grinding plate regardless of the hardness of the specimen. Our machines are built to last and give many, many years of productive service. The frames and cabinets are made of high tensile strength aluminum alloy and exhibit great strength and rigidity. Every unit is constructed entirely from stainless steel, brass and aluminum so rust and other deterioration has been eliminated.
