G14-71 Common Rail Injector Nozzle Face Grinding Machine

G14-71 common rail injector Nozzle Face Grinding Machine

The G14-71 is a dedicated nozzle face grinding machine designed for the maintenance of common rail injectors used on modern diesel engines. The grinding height reaches 80 mm, which covers the full nozzle body length of most Bosch, Denso and Delphi common rail injectors found on light, medium and heavy-duty diesel applications.

The machine is built around a precision magnetic chuck that holds the injector body rigid during lapping, while the high-frequency spindle runs at up to 4500 rpm and is fed by a hand wheel with micrometer-style down and rise scale. A separate cooling pump on AC220V 50Hz keeps the diamond grinding wheel clean and the workpiece temperature stable, so the injector nozzle sealing face stays flat within microns.

The unit is sized 40 x 40 x 50 cm and weighs 85 kg, which makes it bench-friendly in a workshop or a mobile repair station. It ships with a magnetic chuck, T-shape wrench and cross wrench as standard, so technicians only need to provide their own injector adapters and polishing paste to start working on a Bosch 0445110 series, Denso G2/G3 series or Delphi DFI 1.5 injector in seconds.

This is a complementary tool to any common rail injector test bench. After ultrasonic cleaning or nozzle seat repair, the injector can be transferred to the G14-71 to resurface the nozzle face before being reinstalled, which restores atomisation quality and stabilises injection quantity.

Frequently Asked Questions

Q1: Which injectors can the G14-71 service?
A1: The machine is designed for common rail injectors including Bosch 0445110 / 0445115 series, Denso G2 / G3 series and Delphi DFI 1.5 series solenoid injectors. Piezo injectors can also be processed with the proper adapter.

Q2: What grinding wheel is used on this machine?
A2: The machine uses a standard diamond cup grinding wheel. Replace the wheel when surface flatness decreases to maintain grinding quality.

Q3: Does the machine require an air supply?
A3: No compressed air is required. The spindle is driven by a 380V 50Hz three-phase motor and the cooling pump is powered separately on AC220V 50Hz.

Q4: What is the recommended polishing paste?
A4: For best results use a fine diamond lapping compound on the magnetic chuck face together with light hand pressure; finish with lapping oil to clean the nozzle face.

Q5: Is on-site training available?
A5: Remote diagnostics and on-site commissioning are available through Beacon after-sales; please contact us on WhatsApp for schedule and conditions.
