How to correctly install planer knives on the machine: instructions
For safe and high-quality operation, it is important to mount the knives correctly and follow the machine’s setup requirements.
- Preparation: Turn off the machine and clean it from dust and chips.
- Removing old knives: Carefully loosen the fasteners, remove the knives, and store them in a protective case if you plan to reuse them.
- Installing new knives: Ensure the size and parameters match. Insert the knife into the slot, lightly secure it, and check that the cutting edge is aligned with the table surface.
- Height adjustment: The knife should protrude 0.8–1.2 mm above the cutterhead. Check using a straightedge on the table: when the head is rotated manually, the straightedge should move forward 2–3 mm.
- Final fastening: Tighten the fasteners evenly and make sure there is no backlash or unusual sounds.
- Testing: Run the machine idle — there should be no vibrations or abnormal noise.
Tips: Use knives recommended for your equipment, avoid dull or unevenly sharpened knives, and check the fastening every 10–15 hours of operation.
How to choose the right jointer knives for your equipment
For efficient performance, the tool must match the type of machine and the material processing requirements. Proper selection helps achieve a quality finish and extends tool life.
- Jointer (surface planer): Used for flattening surfaces and removing irregularities — cutting-edge geometry is crucial.
- Thickness planer: Designed for precise thickness reduction — knife sharpness and strength are essential.
- Straight-spindle milling machines: Used for fine finishing — require rectangular knives with secure clamping.
The tool must match the cutterhead dimensions: length, thickness, width, and fastening type. Before purchasing jointer knives, always verify compatibility and intended use.
The Leniv DS series is the optimal value-for-money solution.
