Fully Automatic Saw Chain Sharpener.

Sharpens all sizes from 1/4" to 3/4" Harvester Chain. Even Pointed Tooth (Pack Cutting) Chain.
The Dinasaw "T-Rex" is fast, extremely accurate and will sharpen most styles of chains. Size is not important. From the small arborist chain through to 3/4" harvester** chain, even Pointed Tooth** (pack cutting) chain. All sharpened automatically and with very few adjustments needed when changing between chains.
Fast is good, especially when it comes to sharpening. High feed speed introduces less heat to the teeth thereby maintaining the metal's temper. The T-Rex can grind up to 60 teeth per minute, with both left and right hand teeth sharpened in the one pass.

Unsequenced joins are not a problem as the T-Rex can look for the next tooth and correct the grind angle to suit. Automatic operation at up to 50 teeth per minute frees you for other jobs. The machine can be bench, floor or wall mounted . The positive cam operated chain clamp ensures the tooth is securely held only while being ground and then immediately released to allow indexing of the next tooth.
