How to Use CNC Router Hold Down Clamps

CNC router hold down clamps are an essential tool for any CNC router user. They are used to secure the material being cut to the router table, ensuring that it does not move during the cutting process. This is important for ensuring accuracy and safety. In this article, we will discuss how to use CNC router hold down clamps and the different types available.

Types of CNC Router Hold Down Clamps

There are several different types of CNC router hold down clamps available. The most common type is the T-slot clamp, which is designed to fit into the T-slot of the router table. This type of clamp is adjustable and can be tightened to secure the material in place. Another type of clamp is the vacuum clamp, which uses suction to hold the material in place. This type of clamp is ideal for materials that are difficult to secure with a T-slot clamp.

Preparing the Material

Before using a CNC router hold down clamp, it is important to prepare the material. This includes ensuring that the material is flat and free of any debris or obstructions. If the material is not flat, it can cause the clamp to slip and the material to move during the cutting process. It is also important to make sure that the material is securely attached to the router table. This can be done by using double-sided tape or other adhesives.

Using the Clamp

Once the material is prepared, the next step is to attach the clamp to the router table. For a T-slot clamp, this involves inserting the clamp into the T-slot and tightening it until it is secure. For a vacuum clamp, the material should be placed on the router table and the clamp should be attached to the material. Once the clamp is in place, it should be tightened until it is secure.

Cutting the Material

Once the clamp is in place, the material can be cut. It is important to ensure that the material does not move during the cutting process. This can be done by using a slow feed rate and making sure that the material is securely held in place by the clamp. Once the cutting is complete, the clamp should be removed and the material can be removed from the router table.
