CNC Machinist

Company Profile

Dynacast Peterborough is known for its multi-slide technology, standard die casting with integrated automation, and IMA (Injected Metal Assembly) precision zinc manufacturing. IMA offers a unique process where precision tooling is combined with metal alloys and is used to join multiple components into a ready‑to‑use assembly with a single operation. Dynacast Peterborough is dedicated to designing, building, manufacturing, and delivering quality die cast components.

Below are additional details about what is offered at the Peterborough location:

• 40 multi-slide proprietary zinc die casting machines ranging from 12 to 21 tons
• 5 multi-slide proprietary zinc die casting machines ranging from 70 to 200 tons
• Injected Metal Assembly (IMA) up to one ton
• Precision tool building with in-house capabilities
• Design, prototyping, and modeling services
• Wide range of finishing surfaces available including tumbling, polishing, shot blasting and thermal de‑burring
• Cosmetic or protective coating equipment either through certified suppliers or in‑house
• Wide range of secondary operations including CNC machining, tapping, reaming, and drilling

The CNC Machinist will efficiently program and operate a Computer Numeric Control (CNC) Jig Grinder, or combination CNC Mill, or CNC Lathe to machine tooling and related components to close tolerances and drawing specifications, while maximizing cutting parameters, machine utilisation and efficiency.

Completing programming set up and operating any of our CNC machines to achieve maximum efficiency while producing optimum quality product.

• Review project complex drawings and blueprints, identify and cut materials to size (where required);
• Determine the complex fixturing, tooling and/or electrodes and flushing method required as outlined on the work priority list and assemble into a job box;
• Make, grind, (re) dress and sharpen special tool bits, cutters, boring tools, etc. as required for odd shapes and special applications;
• Machine and produce finished cavity electrodes to the requirements of the supplied drawing;
• Calculate work‑piece set‑up required to achieve design features, and determine machine tools, feeds, speeds, electrodes and flushing methods, etc. required to achieve maximum metal removal, best possible finish, size and tool life (i.e. carbide versus high‑speed steel);
• Generate part program functions for the machine to specifications identified on the drawings and in the production file;
• Create and store programs on the PC using CAD/CAM software, and download programs from PC to CNC machines as needed;
• Stage the work‑piece, establish the zero datum point to set the tool, and machine through the various stages and operations;
• Inspect and measure parts using appropriate measuring tools, at various stages of the machining process to ensure compliance to rigid dimensional specifications, document data, input work hours into the system to close out the work order, and release for appropriate distribution;
• Consult with required individual(s) to resolve machining/operations issues identified that may impact quality part production, revise set‑up and machining programmes on the system as required for part improvement or new tooling, electronically file to the PC, and document in the production folder;
• Select and use customer Macro programming systems to accommodate variables in the program such as quantities, draft angles, radii, compound angles, special contours, etc, and write manual programme when necessary;
• Document, update and maintain stored programmes, computer parameters and tooling specifications on floppy disc (i.e. engineering changes);
• Monitor/visually check the electrode condition and wear before each use, redress when applicable and check dimensionally before use, and plan/prepare for new or replacement electrodes to the CNC machining operation stage.

To perform miscellaneous routine operations and maintenance functions to support efficient machine and department operations.

• Design and manufacture specialty tooling and fixturing to accomplish a variety of high‑complexity projects, work‑pieces, and prototypes as required;
• Inco…
