➡️ FAQ - Frequently Asked Questions

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

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

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

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

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

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 saws and more precise cuts. This facilitates achieving a smooth cut surface and increases work efficiency.
2. Cutting fresh wood (wet):Linear speed: from 40 m/s to 70 m/sSpeeds are slightly lower because fresh wood is softer and stickier. Working at lower speeds reduces the risk of jamming, overheating, and blade clogging due to resin and moisture.

These speeds may vary depending on the type of machine, 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 efficient cutting.

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

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