Efficiency of Fully Automatic Chain Sharpener

The efficiency of a fully automatic chain sharpener depends on various factors, including the design and technology of the sharpener, the quality of its components, and how well it is maintained. Generally, fully automatic chain sharpeners are designed to streamline the process of sharpening chainsaw chains, making it quicker and more convenient compared to manual sharpening methods.


Fully automatic chain sharpeners automate the sharpening process, reducing the time and effort required compared to manual sharpening. They typically have features like motorized chain advancement, automatic angle adjustments, and depth gauges to simplify the sharpening process.


Automation ensures a consistent sharpening angle and depth across all teeth of the chainsaw chain. Consistency is crucial for maintaining optimal cutting performance and prolonging the life of the chain.

Ease of Use

The efficiency of a fully automatic chain sharpener also depends on how user-friendly it is. Intuitive controls, easy setup, and clear instructions contribute to a smoother and more efficient sharpening experience.


Fully automatic sharpeners are generally faster than manual methods. The speed at which the sharpener can sharpen a chain may vary depending on its design and the power of the motor.


Some automatic chain sharpeners are designed to accommodate various chain sizes and types, increasing their versatility. A versatile sharpener can handle a range of chains, making it suitable for different chainsaws.

Build Quality

The durability and build quality of the sharpener affect its long-term efficiency. A well-built sharpener with high-quality materials is likely to last longer and require less maintenance.

fficiency of a fully automatic chain sharpener can also be influenced by the user’s experience and familiarity with the machine. Proper maintenance, including regularly cleaning the sharpener and ensuring that it remains in good working condition, contributes to its overall efficiency and longevity.

When considering a specific fully automatic chain sharpener, it’s advisable to read user reviews, check product specifications, and possibly seek recommendations from professionals in the field to determine its efficiency and reliability.


The Dinasaw “T-Rex” has arrived and will relieve you from the drudgery of chain sharpening. The T-Rex is fast, extremely accurate and will sharpen most styles of chains.

From the small arborist chain through to 3/4″ harvester 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 cutters thereby maintaining the metal’s temper. The T-Rex can grind up to 30 cutters per minute, with both left and right hand cutters sharpened in the one pass.

Unsequenced joins are not a problem as the T-Rex can look for the next cutter and correct the grind angle to suit. Automatic operation at up to 30 teeth per minute frees you for other jobs.

The machine can be bench, floor or wall mounted with optional stands.

The positive cam operated chain clamp ensures the cutter is securely held only while being ground and then immediately released to allow indexing of the next cutter.

Outstanding performance at minimal cost!
