➡️ FAQ

❓ 1. When to choose a left-threaded shaft versus a right-threaded one?

• Choose a left thread if you want the circular saw to rotate clockwise (looking from the nut side).
• Choose a right thread if you want the circular saw to rotate counter-clockwise (looking from the nut side).

This ensures the nut tightens during operation, preventing it from loosening.

❓ 2. What should be the linear speed of a circular saw?

The recommended linear speed for circular saws for wood cutting depends on the type of wood (dry or green) and the specifications of the blade itself. General values are as follows:

1. Cutting dry wood:Linear speed: from 50 m/s to 100 m/sHigher speeds (closer to 100 m/s) are preferred for larger diameter blades and more precise cuts. This facilitates achieving a smooth cutting surface and increases work efficiency.
2. Cutting green (wet) wood:Linear speed: from 40 m/s to 70 m/sSpeeds are slightly lower as green wood is softer and stickier. Working at lower speeds reduces the risk of jamming, heating, and resin and moisture clogging the blade.

These speeds may vary depending on the type of machine, blade material, number of teeth, and tooth shape. It's also important to follow the manufacturer's recommendations for the circular saw and machine to ensure safe and effective cutting.

❓ 3. How to select pulleys for a table saw?

Depending on the diameter of the circular saw (including recommended RPM) and the electric motor RPM – the pulley configuration can vary. Below are some of the most popular configurations for a medium linear speed of 55m/s:
