Amana Tool 61299 In-Sand 3-55/64" x 1/2" Non-Random Orbital CNC Sander

Warning: The max RPM for the 61299 Dynamically Balanced non Random Orbital Sander is 8,000. Working with higher rotation speed can cause damage to the machine spindle.

Please note: After one hour of sanding, stop and turn the power off on your CNC machine. Inspect to ensure the tool spins freely. Repeat after each hour of sanding.

Designed for CNC Sanding: Wood and Resin.

IN-SAND Dynamically Balanced Non-Random Orbital CNC Sander with 3.5mm Orbital Stroke and 1/2" Shank

This CNC orbital sanding tool is designed to use with any 4” sanding disc (included) according with the finish required. Full set of instructions included.

Understanding the Sander Before Use:

The In-Sand sander comes with two different springs, the hard spring comes installed on the tool and the soft spring is included in the package. The springs look very similar, but by compressing the springs you can feel the difference between the stiffness of them.

The In-Sand is a non-random orbital sander, which operates in a fixed, predictable motion. The sander is dynamically balanced from the factory, using Part #5 as the balancing element. DO NOT ADJUST THIS PART. If the red mark on Part #5 is not aligned properly to the red mark on the tool body, please contact the Amana Tool technical support team for assistance at (800) 445-0077.

A spring inside the sander ensures constant pressure is applied to the sanding pad. The amount of pressure is determined by setting the “depth of cut” in your software. Do not exceed the maximum spring compression by setting your cut depth too deep, for best results use our recommended settings.

The hard spring applies a maximum pressure of 22lbs (10kg) with a maximum compression of 0.078" (2mm). The recommended “depth of cut” setting is 0.04" (1.01mm). This spring is best used for flat surfaces. The sander should not be used to flatten surfaces, the surface must already be flat before sanding.

The soft spring applies a maximum pressure of 4.4lbs (2kg) with a maximum compression of 0.1" (2.6mm). The recommended “depth of cut” setting is 0.08" (2.03mm). This spring is best used for rough, but relatively flat surfaces. The maximum deviation in the surface cannot exceed the maximum compression of the spring. On uneven surfaces, it will follow the ups and downs of the material, which may be helpful in certain cases like using rough sawn wood where you want to smooth it out, but not remove the rough sawn look, for example.
