Intermac CNC Spare Parts

Verify the product reference in the Intermac CNC collection

The four visible product names in the Intermac CNC collection are Biesse Rover 29 mm and 74 mm vacuum cups, with quarter and half shapes. The page title therefore does not establish Intermac compatibility. It is important to distinguish how products are grouped from the machine for which a part has been verified. Intermac is a machine brand within the Biesse group and covers different processing applications, but that relationship does not show that a specific cup fits an Intermac table. This page describes the listed products and explains how to check the correct part number, mounting dimensions, table type and machine-catalogue match. Do not turn the product name into a compatibility claim before that match is established.

The listed 29 mm and 74 mm cups

The 29 mm and 74 mm values in product names indicate different catalogue sizes. Confirm in the product page whether a value describes the cup’s outside diameter, top contact diameter or another measurement. Cup height, base diameter, screw or clip, vacuum-port position and seal cross-section should also be recorded. Two cups may share an outside diameter but have a different height, lower connection or perimeter sealing shape. Compare the product photo with the old part in the same orientation. Show the underside, centre hole and mounting base. If several cup shapes are used on the machine table, identify the required mounting point by the position number in the drawing. A single nominal value is not enough to confirm fit.

What quarter and half shapes indicate

A quarter or half description may identify a partial perimeter or cup geometry. Do not assume that wording in a product title uses the same terminology as the machine maker’s parts catalogue. The shape can affect how the cup sits on an edge or corner and how far its seal surrounds the contact area. The machine drawing should confirm mounting direction, vacuum-channel location, whether the part sits at a corner or straight edge, and how it supports the neighboring cup. Before removal, photograph the top and underside of the cup, its table position and adjacent components. If the old part is bent, crushed or missing its seal, use the parts drawing and a sound example from the same position as primary references.

How to confirm that a part is for Intermac

Start with the machine plate: model, serial number and production period. Then locate the relevant mounting drawing for the vacuum table, pod or workholding arrangement in the parts catalogue. Check whether the drawing item number matches the OEM or supplier code of the listed cup. If the product bears a Rover code or brand, record that reference clearly; do not assume it is a cross-reference for Intermac. Compare the product’s outside dimensions, height, base, sealing profile, connection and vacuum path with the part removed from the Intermac. Without a manufacturer document, verified alternate part number or reliable catalogue entry explaining a different brand name, compatibility remains unresolved. If the machine has been adapted, its present mounting may differ from the original catalogue configuration.

Geometry of the cup and table connection

A cup forms a sealing and contact point between the workpiece and a table or vacuum pod. For that connection to match, the upper diameter is only one dimension; the underside and mounting direction must also align. Compare the gasket channel, connection centre, screw pattern, locking surface, cup height and vacuum inlet using a drawing or the old part. Different table systems can use a fixed table, modular pods, another pad adapter or a different vacuum zone arrangement. The text here does not establish that a listed cup uses the same architecture as your table. A photo of the mounting point with caliper measurements is more useful than a guess based on the product name. Follow the maker’s parts instructions and the site’s technical authority before making any adaptation.

Assess a change in vacuum hold as a system issue

A moving panel or an unexpected vacuum level during CNC work can relate to a worn cup, but similar symptoms may involve a leak, obstructed connection, zone selection, surface cleanliness, valve, hose, pump or the supported area of the workpiece. Photograph a cut or compression mark on the cup, but do not treat it as a complete explanation of system performance. Record which vacuum zone was active, the program where the problem occurred, the workpiece shape and maintenance history. If similar cups sit next to one another, identify the affected location by its position code. System checks and replacement should follow the maker’s procedure and be carried out by authorized maintenance staff. A product description cannot diagnose a machine fault remotely.

Information for a purchasing request

Along with a short note such as “vacuum cup for Intermac,” provide the full model, serial number, production year, table or pod type and the position number from the parts catalogue. Transcribe every punctuation mark in the code on the old product. If there is no readable code, list outside diameter, total height, base dimensions, mounting centres, vacuum inlet and seal channel separately. Photos should show the top, underside and mounting location alongside a ruler or caliper. If the live collection calls the product Biesse Rover, include that reference in the request and mark whether a compatibility check is still pending. State quantity by position and cup shape if more than one is needed. Resolve any open cross-reference with a technical reviewer before purchase approval.

Cross-check related product collections carefully

The [general CNC spare-parts collection](/en/collections/cnc-yedek-parca) includes a broader selection of vacuum and tool-holding items. [Biesse Rover CNC parts](/en/collections/biesse-rover-yedek-parca) can be reviewed for cups carrying a Rover name. Vacuum-related listings also appear in [IMA CNC](/en/collections/ima-cnc-yedek-parca), [SCM / Morbidelli CNC](/en/collections/scm-morbidelli-cnc-yedek-parca) and [Homag / Weeke CNC](/en/collections/homag-weeke-cnc-yedek-parca). These links help navigate catalogue headings; seeing the same cup in a collection is not proof of an Intermac part-number cross-reference. Do not present items in this collection as Intermac-compatible without a manufacturer drawing, part code or verified catalogue match. That distinction helps prevent a similar-looking part with a different base from being accepted as the correct replacement in a supplier quote.

Post-selection mounting checks

Once the part match has been verified, replacement should follow the site procedure for machine isolation and vacuum lines. Before installation, place the new and old components side by side and compare key dimensions, base geometry and seals. If the cup does not seat on the pod, the connection is forced or the vacuum passage does not line up, stop and review the catalogue and measurements instead of forcing it into place. After installation, an authorized technician should follow the maker’s instructions to check seating, sealing and vacuum hold. The technician should choose an appropriate test workpiece and safety conditions. Keep the old-part photo, new product code, mounting location and test result in the maintenance record. If the cross-reference remains uncertain, leave that status explicit in the record so a later search does not treat it as confirmed.
