90mm CNC Dust Proof For CNC Engraving Milling Machine Dust Cover

A 90mm CNC dust cover for CNC engraving and milling machines, made from an iron body and white nylon brush. It mounts on a 90mm spindle to keep chips off the work area. The sliding door design opens for tool changes without removing the cover. Confirm your spindle diameter is 90mm before ordering. The body is iron; the brush is nylon. It is a spare part for woodworking machinery. Send your spindle size and machine details when enquiring.

Chips pile up around the spindle during engraving and milling, and they get into the collet and the cut. A dust cover with a brush skirt contains them at the source. Without one, the operator stops to clear debris, and the cut suffers.

This is a 90mm CNC dust cover with an iron body and a white nylon brush. It fits CNC engraving and milling machines with a 90mm spindle. To confirm fit, measure the spindle outside diameter with a caliper; if it reads 90mm, this cover matches.

The cover mounts around the spindle, and the brush skirt sits against the work surface. A sliding door opens for bit changes without removing the cover. The flexible nylon brush follows the surface as the tool moves, so chips stay under the cover.

Supplied as a spare part for woodworking machinery, this dust cover comes in white with an iron body and nylon brush. No customisation or packaging details are stated. When enquiring, send your spindle diameter, machine type and the quantity you need. Supply comes from the same range as the rest of the catalogue. Send the machine model with the enquiry so the fit is checked before dispatch.

What the specification fixes, and what it leaves to the machine:

• Spindle fit check — Measure the spindle outside diameter; a reading of 90mm confirms this dust cover fits the machine before you order.
• Brush skirt containment — The nylon brush forms a flexible skirt around the cutter, holding chips and dust close to the extraction point during milling.
• Sliding door access — A sliding door in the cover opens for bit changes, so the operator does not remove the whole cover between tools.
• Iron body wear point — The iron body takes knocks from clamps and fixtures; it holds its shape where a thinner cover would bend out of alignment.
• Nylon brush flexibility — Nylon bristles flex over raised areas and edges, keeping the skirt in contact with the work surface as the tool moves.
• White finish visibility — The white finish makes the cover easy to see against dark workpieces and machine tables, helping operators spot chips trapped under the brush.
• Spare part replacement — As a spare part for woodworking machinery, the cover replaces a worn or damaged unit without changing the machine setup.
• Mounting around spindle — The cover mounts around the 90mm spindle; check that the mounting area is clear of clamps and fixtures before fitting.

What changes on the shop floor when the right part goes back in:

• Chips stay at the cutter. The nylon brush skirt holds chips and dust around the cutter instead of letting them spread across the table, so the operator spends less time clearing the work area.
• Bit changes without removing the cover. The sliding door opens for access to the bit, so the operator does not unbolt the cover between tools, which saves time on jobs with several cutters.
• Fit confirmed by one measurement. A caliper reading of 90mm on the spindle outside diameter confirms the cover fits, removing guesswork before the order is placed.
• Iron body holds alignment. The iron body resists bending from knocks and clamps, so the cover stays in position around the spindle and the brush keeps contact with the surface.
• Brush follows the surface. Nylon bristles flex over raised areas and edges, keeping the skirt against the work as the tool moves, which maintains chip containment on uneven cuts.
• Visible white cover. The white finish stands out against dark workpieces and tables, so an operator can see chips trapped under the brush and clear them before they reach the cut.

Measure your spindle outside diameter; if it is 90mm, this cover fits. The 90mm size is the spindle size for this dust cover.

The body is iron and the brush is nylon. The cover is white. These materials are stated for this 90mm dust cover.

Open the sliding door to access the bit. The sliding door design allows bit changes without removing the cover from the spindle.

The brush is nylon and is part of the cover. No separate brush replacement is stated; inspect the brush for wear and replace the cover if needed.

It suits CNC engraving and milling machines with a 90mm spindle. It is a spare part for woodworking machinery.

This page is for the 90mm size. Other sizes are not stated here; send your spindle diameter with your enquiry to confirm availability.

Mount the cover around the 90mm spindle and check the brush sits against the work surface. Check the sliding door moves freely before use.

Send your spindle diameter, machine type and the quantity you need. These details confirm the 90mm cover matches your machine.
