Rotary tool that removes hard or soft materials similar to a rotary file. A bur’s teeth, or flutes, have a negative rake.
Machining operation in which material is removed from the workpiece by a powered abrasive wheel, stone, belt, paste, sheet, compound, slurry, etc. Takes various forms: surface grinding (creates flat and/or squared surfaces); cylindrical grinding (for external cylindrical and tapered shapes, fillets, undercuts, etc.); centerless grinding; chamfering; thread and form grinding; tool and cutter grinding; offhand grinding; lapping and polishing (grinding with extremely fine grits to create ultrasmooth surfaces); honing; and disc grinding.
EXAIR’s new Mini Cooler with dual point hose kit provides a stream of 20 degrees F (-7 degrees C) cold air to prevent heat buildup, reduce downtime and increase productivity. It is effective on small-part machining operations to eliminate burning, melting and heat related breakage. The dual point option allows the cold air outlet to be directed at two different spots when cooling larger diameter tools, cooling two separate points or opposite sides of a material or process. Single point systems are also available.
The Mini Cooler incorporates a vortex tube that converts an ordinary supply of compressed air into cold air at 20 degrees F (-7 degrees C). Flexible tubing that holds its position is provided to direct the cold airflow. An adjustable magnetic base allows easy positioning. Durable stainless steel construction and an absence of moving parts assures maintenance free operation.
The Mini Cooler is ideal for applications where liquid cooling cannot be used due to part contamination or cost. Tolerances, product finish and production rates can improve dramatically. In addition to preventing premature tool wear, the Mini Cooler is ideal for cooling sewing needles, blades, small tools and lens grinding. All Mini Coolers are CE complaint and operate at a quiet 76 dBA.
