Cnc z axis zero presetter

• Function: The presetter is used to establish the tool's position (zero point) along the Z-axis (depth) of a CNC machine. This is often called "touching off".
• Operation: The user places the presetter on the workpiece or table and then lowers the spindle until it makes contact with the presetter's top surface. This contact point, often indicated by a light or a dial reading, is then used to set the Z-axis zero in the machine's control system.
• Benefit: It provides a fast, accurate, and repeatable way to set the tool height, which minimizes errors and improves safety compared to manual adjustments.
• Design: Many models feature a spring-loaded plunger or measuring surface to absorb impact and prevent the tool bit from breaking. The base is typically magnetic to hold it securely on the machine table or workpiece.
