CNC Spare Parts

Identify the right component for a CNC machine

Woodworking CNC equipment depends on several components working together for vacuum workholding, tool changes and auxiliary air paths. This broad collection includes vacuum cups and supports, vacuum pads and sponges, sealing strips and gaskets, lower bearings, filters, tool-holder forks, connection pieces and air valves. Some product names carry references such as Biesse Rover, SCM, Morbidelli, Alberti or Weeke; that does not mean every listing belongs to the same manufacturer or fits every machine in that family. A collection is a way to browse listed items, not a compatibility chart or a shared standard for all CNC systems. Before ordering, check the complete machine model together with the current component’s code, geometry, connection and the vacuum zone or tool station where it is installed.

Vacuum cups and pod-mounted supports

Vacuum cups create a contact surface beneath a workpiece in a vacuum workholding system. Product names may include a diameter, length-width-height dimensions or a shape description such as quarter, half or full. Those terms describe the listed geometry; they do not prove that its mounting matches your machine. Compare the cup’s outside dimensions, vacuum port, attachment type, height and orientation with the existing part. A sealing channel, vacuum passage and contact surface against the table or pod also matter. Some products may use a movable or swiveling mechanism or a particular jaw or adapter connection. Even where the nominal diameter matches, the base, vacuum hole, locating pin or sealing path may differ. Provide top, underside and mounting-face photos of the old item to make those comparisons clear.

Vacuum pads, sponges and sealing elements

Vacuum pads and sponges are contact components available in different dimensions and profiles. This collection may include round, oval and rectangular pads as well as sponges identified by catalog names such as 60 or 115. Use the product image and detail to confirm which edge, diameter or thickness a dimension refers to. An old sponge may have compressed or torn, so its thickness after removal can be misleading. The channel’s inner dimensions, working height, cross-section and support piece all affect selection. Vacuum rubber, sealing strips and gaskets can also differ by channel width, profile, corner geometry, joint and whether the listing describes a full, half or quarter perimeter. Compare the required length and end shape with the machine drawing. Cutting a gasket sold for another model to fit is not appropriate in every application.

Filters, lower bearings and connection parts

Filters in a vacuum circuit are individual components that should be assessed in the context of the surrounding system. The listings include bronze filters named for Biesse Rover and described as round or rectangular. Shape and connection dimensions provide a starting point for physical identification. Check the filter body, seat depth, contact face and any flow-direction marks on the existing item. A dirty filter alone does not prove the source of a system-wide loss of vacuum; hoses, fittings, valves, seals and the pump may also need to be reviewed by a maintenance professional. Delrin lower bearings and lower-bearing seals are listed as parts of a table or related mechanical carrier group. A domed versus flat gasket, thickness and outer profile can distinguish two similar-looking options. Names such as “moon connection” or air valve require more context: do not infer a function or connection standard without the product description, mounting image and maker’s code.

Tool-holder forks and HSK descriptions

Tool-holder forks are physical parts that help retain a tool in a magazine or parking arrangement. Product names may include a standard reference or a description such as Weeke HSK 63. That wording identifies how the listing is named; it does not by itself verify the spindle interface, holder standard, magazine layout or tool diameter in your machine. Measure the old fork’s mouth width, retention depth, body height, mounting holes and orientation. A broken tip, permanent opening, rub mark or deformation can help identify the part, but a damaged tool-change component should not remain in operation where it could affect safe machine use. HSK is a family of holder standards, not a single universal size. Confirm the toolholder and magazine reference in the machine documentation as well.

Match the machine and part number

Begin with the machine plate: manufacturer, full model, serial number and production period. The general label “CNC” covers routers, nesting systems, drilling centers and stone-working machines; it cannot tell you how a vacuum table or tool magazine is built. Copy the code printed on the product exactly, preserving suffix letters, zeros and punctuation. If there is no readable original number, record a measurement set. For cups and pads, include outside dimensions, height, attachment spacing and channel profile. For filters, include body, base and seat dimensions. For forks, include mouth and fastening dimensions. A wide view of the mounting location, a close-up of the part markings and the exploded view in the machine catalogue can help distinguish similar listings.

Interpreting symptoms carefully

A workpiece moving on a vacuum table can be related to a worn pad or seal, but zone selection, surface cleanliness, hoses, valves, pump condition and the workpiece shape can all affect the result. Do not infer that one particular cup has failed from a single symptom. A tool sitting loosely in its magazine may warrant checking the fork geometry, but magazine adjustment and tool dimensions should also be reviewed. Follow the maker’s maintenance instructions when servicing a filter. Cleaning a vacuum system with compressed air or substituting a material outside the site procedure is not a general recommendation. Logging when the fault occurs, the program or operation, CNC axis or vacuum zone, maintenance history and components changed makes recurring issues easier to investigate.

Some listings can contain a product reference associated with another manufacturer or machine label, so the code and dimensions still need to be checked. This CNC collection is a broad starting point for vacuum workholding, tool management and related connections. For panel transport and pressure components on sizing equipment, see [panel sizing saw parts](/en/collections/panel-ebatlama). If the required part is not listed, share the machine plate, old part code and photos so the item can be investigated before a purchase decision is made.

Record position and operation in a CNC request

Along with a product code, describe where the component sits on the CNC machine: which pod, vacuum zone, magazine station or lower-bearing group. Code and mounting point together help distinguish pads, cups and connectors listed under similar names. Note the program and position where a symptom appears during workholding or a tool change. This does not prove the cause; it clarifies which product family to inspect. In a purchasing request, state which part supplied the measurement, whether it is worn and the manufacturer drawing reference. If no full code can be read, say so and send the photo with the machine plate; do not record a product-name or brand match as a verified part number.
