J & J Custom Blade Sharpening Service is superior to the competitors service because of the knowledge gained by operating portable sawmills daily in all applications including hardwoods softwood, large diameter and small diameter logs, winter and summer weather conditions. We don’t just sharpen blades we experience the entire spectrum of the sawmill business. This experience teaches the best blade geometry and set for each application. This overall knowledge helps us to understand our customer(s) issues and needs to make the appropriate recommendations to enhance their total sawmill experience and blade knowledge.
Our Blade sharpening is tailored to the customer needs. Whether you are running high horsepower, high production or low horsepower, manual sawmills the blade geometry is adjusted to your specific sawmill parameters. The blade geometry and set is individualized to specific customer applications determined by the wood species, hardwoods or softwoods.
The most popular applications by name are:
The 7° hook angle with a deeper gullet depth and set to a specific application or to your individual request. This is the best profile for all around sawing requirements.
The 4° hook angle, with a shallower gullet is recommended when sawing extreme hardwood at slower feed rates.
The 10° hook angle with increased blade set, recommended when sawing softwoods that have been defoliated by insect infestation.
Whatever the situation the customer feedback is always considered and adjusted as necessary to provide the best application parameters. The above profiles are not to be confused with any manufacturers brand or specifications, they are unique to each customer requirements.
To ensure the quality of service each blade goes thru the following process:
- Each blade is washed and cleaned prior to sharpening. Rusty or rusted blades cannot be cleaned. All rusty blades will be sharpened and set in normal fashion.
- An inspection is performed to check for cracks in the gullet or teeth broken off. All blades that have cracks will be discarded. With the blade owners permission the blades with broken teeth will be assessed to determine if they will provide a quality cut or will be also discarded.
- The blades are then sharpened with a dual grind. The first grind is to remove any non-visible fracture fatigue cracks in the gullet and restore the entire tooth profile that may have been damaged by hitting stones or small debris. The second grind provides a smooth surface along the complete profile to insure a sharp edge at the cutting surface.
- Random blades are checked for flatness and roll leveled if required. Not all blades need to be leveled. Quality standards for flatness set by the blade manufacturer dictates the need for roll leveling the blade.
- Every blade is set per the customer request or sawing application. Blade set is usually adjusted using previous experience.
The maximum length sharpened is 18’. All blades with ¾” tooth spacings require 20% premium to standard blade sharpening fees. All blades shipped for sharpening will be repackaged in the original container and shall be return shipped Fedex; assessing only the actual shipping charges.
