Instruction Manual

Dust Collection Module

Chip evacuation is an important part of CNC but is usually ignored by other desktop-level CNC

machines. Carvera has a built-in dust collecting and filtering system that can literally achieve

dust-free machining process when doing light weight task and highly reduce the mess level when

doing long time jobs .

1. Use case: The key factor in deciding whether to use the dust collection system is the interference

situation. If the machining path has obstacles that block the dust shoe, do not use it. Generally, the

dust collection could be used for machining thin and flat workpieces, such as plates. We suggest

moving and locking the dust shoe to the highest position when machining thick and irregular work-

pieces. And remove the dust shoe entirely when using the 4th axis.

2. Lock/Unlock: To fit Carvera's automatic tool change function, we designed the dust shoe to be able

to slide up and down. As described earlier in the manual, pull out the black knob, and you can switch

between lock and unlock states by rotating it every 30 degrees.

3. Install/uninstall: When dust collection is not needed, you can move the dust shoe to the highest

position and lock it, or you can loose the hand screw that fixes the dust shoe to the linear rail and

remove the dust shoe. Use the pipe holder as shown in the figure to fix the dust pipe.

4. Dust bin: Clean the dust bin in time when the milling job is done.

Note: The milling bits are sharp, be careful when install and uninstall collars.

Bit Collar Installer

To cooperate with Carvera’s auto tool changing mechanism, you need to use the collar installer to

install the collar when replacing new milling bits. The collar installer can do both installation and

removal. (the collar is reusable).

Collar installation: As shown in the figure, unscrew the front part of the installer. Insert the collar and

the tool. Put in the installation metal ring (support 3.175/4/6/6.35mm). Loosen the tail pressure screw,

screw back the front part, and tighten the tail pressure screw to complete the installation.After the

installation is complete, the collar will be embedded with the tool, leaving a length of about 12mm at

the tail for clamping.

Collar removal: As shown in the figure, unscrew the front part of the installer, put the tool with the

collar. Put in the removal thimble, loosen the tail pressure screw, screw back the front part, tighten the

tail pressure screw, and the removal is complete.
