➡️ FAQ - Frequently Asked Questions

❓ 1. When to choose a shaft with a left-hand thread versus a right-hand thread?

• Choose a left-hand thread if the circular saw blade is to rotate clockwise (looking from the nut side).
• Choose a right-hand thread if the circular saw blade is to rotate counterclockwise (looking from the nut side).

This ensures that the nut will tighten itself, preventing it from loosening during operation.

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

The recommended linear speed for circular saw blades for cutting wood depends on the type of wood (dry or fresh) and the specifications of the blade itself. Generally accepted values are as follows:

1. Cutting dry wood: Linear speed: from 50 m/s to 100 m/s Higher speeds (closer to 100 m/s) are preferred for larger blades and more precise cuts. This facilitates obtaining a smooth cutting surface and increases work efficiency.
2. Cutting fresh (wet) wood: Linear speed: from 40 m/s to 70 m/s Speeds are somewhat lower because fresh wood is softer and more sticky. Working at lower speeds reduces the risk of binding, heating, and clogging the blade with resin and moisture.

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

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

Depending on the diameter of the circular saw (including recommended revolutions) and the rotations of the electric motor - the configuration of the wheels can vary. Below are some of the most popular configurations for an average linear speed of 55m/s:
