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.
WARNING! 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.
IN-SAND™ Dynamically Balanced Non-Random Orbital CNC Sander with 3.5mm Orbital Stroke and 1/2" Shank
Pad Installation & Replacement
1. Hold the spindle with the key (part #6) using the flats on the spindle.
2. Remove spindle (part #2), ring (part #3) and spring (part #4).
3. Clean out any dust and swap the spring if necessary (part #4).
4. Reassemble ensuring the ring (part # 3) is installed with the groove seated toward the top bearing of the spindle (part #2).
5. Press the spindle into housing, and tighten the screw (part #1).
6. (Part #5) helps to balance the tool. It is properly adjusted from the factory, do NOT attempt to remove it!
Save time and money, utilize your CNC machine to sand for you!
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.
Set Up at the CNC Machine
- Check the tool flexibility movement it should be about 3mm.
- Install the IN-SAND™ at the tool holder or directly at the spindle.
- You can measure the IN-SAND™ on the machine measuring device or simply update manually the tool length from pad surface, The diameter should be 4-11/32” (110mm) and not 3-15/16” (100mm) of the orbital movement of the pad.
- The sanding power is defined by the “Milling Depth” the max depth is 1/8” (3.17mm) but our recommendation is 8,000 RPM and milling depth of 0.3 – 0.5mm.
- Use the Option of “Milling Pockets” to control the tool path.
UNDERSTANDING THE SANDER BEFORE USE:
After one hour of usage, stop and turn the power off on your CNC machine. Remove the tool and inspect to ensure the tool spins freely.
they advise to cool off the tool for 1/2 hour before resuming. You sent After 4 hours of usage total, they advise to disassemble the tool and clean it thoroughly, blow with air / wipe it off as best you can.
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.
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.
Includes 20 Replacement Sanding Discs:
10 pack of 80 grit (Medium)
10 pack of 120 grit (Fine)
Knowing which grit sandpaper to use depends on the type of job and what step in the process you are in. The lower the grit numbers, the coarser the disc will be, and the higher the grit, the finer it will be.
- 40 grit: Coarse.
- 80 grit: Medium.
- 100 grit: Medium.
- 120 grit: Fine.
- 220 grit: Fine.
- 440 grit: Extra Fine.
WARNING! The max RPM for this dynamically balanced non random orbital sander is 8,000 RPM. Working with higher rotation speed can cause damage to the machine spindle.
