Chainsaw Sharpener Works Automatically

Chainsaw Sharpener Works Automatically WOODLOT EQUIPMENT Chain Saws 24-3-8 New chainsaw sharpener from Australia will sharpen a chain automatically in less than a minute, says sales representative Ben Hutchinson of Dinasaw Pty. Ltd., Australia. "The Dinasaw sharpener will find its biggest market in the dealers, who often spend hours per day sharpening chains," says Hutchinson. "There are other automatic sharpeners on the market but they cost six to ten times as much and are all slower and more cumbersome." The machine is operated by two cams carried on a common shaft. One cam feeds the chain along while the other oscillates the grinding head up and down. A third cam is situated at the base of the arm to hold the grinder head. It rotates the grinder head from side to side. The electronically-controlled machine actively "looks" for the orientation of the chain teeth, according to Hutchinson. If the cutters are out of sequence (as often happens at the joint) the machine will automatically correct the head angle to suit. The Dinasaw will sharpen up to 60 teeth per minute, making short work of what is usually a tedious job. The Dinasaw can be adjusted to sharpen all chain sizes from the smallest (1/4 in.) to the biggest (3/4 in.). The units come with their own stand or can be bench-mounted for use in the workshop. They can operate on AC or DC current, so you can take them to the woods. Dinasaw Pty. Ltd. holds patents for the chainsaw sharpener in the U.S., Germany, UK and Australia. It is not yet handled by a distributor in the U.S., but negotiations are currently underway. The fully automatic chainsaw sharpener is priced at $1,624 U.S. A semi-automatic model sells for $956 U.S. Contact: FARM SHOW Followup, Ben Hutchinson, Dinasaw Pty.
