➡️ FAQ - Frequently Asked Questions

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

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

This way, the nut will tighten, preventing it from loosening during operation.

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

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. Dry wood cutting: Linear speed: from 50 m/s to 100 m/sHigher speeds (closer to 100 m/s) are preferred for larger diameter saws and for more precise cuts. This facilitates a smooth cutting surface and increases work efficiency.
2. Fresh (wet) wood cutting: Linear speed: from 40 m/s to 70 m/sSpeeds are slightly lower because fresh wood is softer and stickier. Working at a lower speed reduces the risk of jamming, heating, and the blade being clogged by resin and moisture.

These speeds may vary depending on the type of machine, blade material, number of teeth, and teeth 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 choose pulleys for the krajzega?

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