➡️ FAQ - Frequently Asked Questions

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

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

This ensures the nut tightens itself, preventing loosening during operation.

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

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

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 diameter saws and more precise cuts. This facilitates smooth cut surfaces and increases work efficiency.
2. Cutting fresh (wet) wood: Linear speed: from 40 m/s to 70 m/s The speeds are slightly lower because fresh wood is softer and tackier. Working at lower speeds reduces the risk of jamming, heating, and resin and moisture buildup on the blade.

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 table saw?

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