CFT Rizzardi machine tool automation selection

Identify the CFT Rizzardi assembly

Founded in 1987, CFT Rizzardi develops cam driven motion systems and machine tool automation. Its range covers tool changers, magazines, pallet exchange and linear handling. CFT Automation and the cftautomation.it address refer to this manufacturer.

Keep the full CFT Rizzardi name in the enquiry so the identification plate can be matched to the right documentation. A machine can contain assemblies made by several companies. For a retrofit, identify both the machine builder and the manufacturer of the assembly being replaced.

Identification and document package

Start with a photograph of the complete identification plate. Preserve every letter, separator and suffix, then add a close view of the part marking. If a code is unreadable, send an assembly drawing and the relevant item position. State when a drawing belongs to a different machine revision.

Pictures of the mounting face and neighbouring parts help define the assembly boundaries. Include both the removed item and its installed position when possible. This gives the selection process a clear reference for handed parts and different installation orientations.

Tool holder, gripper and tool envelope

Provide the complete tool holder interface, the holders in use and the weight of the heaviest assembled tool. Add the maximum diameter and length, including any tools that need adjacent pockets to remain empty.

A gripper enquiry needs the locating and retention geometry; a pocket enquiry also needs its position and connection to the magazine. Use separate enquiry lines when similarly named assemblies are installed on different machines. Matching the family name is a starting point.

The installed interface and the intended assembly scope still need to be checked.

Magazine layout and exchange position

For a new magazine or changer, send top and side views with the principal dimensions. Mark the spindle position, tool transfer point, movement path and maintenance access. Show areas occupied by guards, services and chip removal equipment.

Photographs of the complete installation are useful when replacing a compact magazine. A layout should distinguish the fixed assembly envelope from the space swept by moving parts.

Record the machine reference points used for the dimensions so that the magazine drawing and the machine drawing can be compared on the same basis.

Drive, signals and cycle control

Record the installed motor, gearbox, supply details and position sensor designations. For a servo driven assembly, include the drive and control information available in the machine documentation. State whether the enquiry covers mechanics alone or also electrical equipment and cables.

A replacement sensor needs its marking, connector details and circuit reference. For a retrofit, define the input and output signals, home positions and exchange permissions.

Include the responsibility for control programming and commissioning in the project scope so that the equipment list has a clear boundary.

Supply boundaries and operating sequence

Separate the changer, magazine, base, grippers, drives and accessories in the equipment list. A pallet or linear handling enquiry should also define the load, centre of gravity, required movements and their sequence.

When replacing part of an existing line, identify the assemblies that will remain in use. For a new installation, describe the cycle from the home position through each transfer and back to home.

This makes the enquiry comparable across equipment options and identifies which connections belong to the machine and which belong to the proposed assembly.

Receiving and installation preparation

Agree the receiving checklist with the supply scope. Compare the marking and quantities against the documents, then check the fasteners, cables and accessories included in the quotation. Keep photographs of the packaging and identification plates before the assembly is released for installation.

A large magazine also needs a planned unloading and temporary positioning arrangement. Give the operating team the documents and the agreed inspection results together.

Mechanical installation and cycle verification should follow the documentation for the particular machine and assembly, with the responsible site personnel involved.

Prepare a usable equipment enquiry

An enquiry can cover both replacement parts and a complete assembly, but list each item separately. Give its model, designation, quantity, purpose and document reference.

Distinguish mandatory requirements from preferred options so that the proposed configuration can be compared with the project brief. Where information is incomplete, list what is available and identify who can answer technical questions.

For a repeat enquiry, attach the previous specification and mark the changes. A clear item list lets engineering review the interfaces while purchasing checks the same scope and quantities.
