G14-71 Common Rail Injector Nozzle Face Grinding Machine

Product Overview and Specifications

The G14-71 Common Rail Injector Nozzle Face Grinding Machine is a precision bench-top grinder designed for workshops that need accurate surface finishing and thickness correction on common rail injector nozzles and copper gaskets. Built on the proven GM-08 platform, this machine combines a precision linear-bearing worktable with a fine-adjustable grinding wheel head to deliver micron-level surface accuracy on small to medium-sized metal parts.

With a 40x40x50cm bench-top footprint and 85KG net weight, the G14-71 fits any professional injector service workshop while delivering industrial-grade precision. Specifications: 7.5kW main motor, 220V (custom 380V available), 75mm wheel vertical travel, 100mm worktable stroke, 2800 r/min spindle speed, 80-100mm wheel diameter, 1-2 micrometer fine adjustment precision.

Typical Applications for Bosch Denso Delphi Injectors

Typical applications span across Bosch, Denso, and Delphi common rail injector repair. The G14-71 is widely used for restoring flatness on copper gaskets and refacing nozzle end faces after machining or heat treatment distortion. Compatible injector nozzle diameters range from 80 to 100mm.

Also suitable for tool-room and repair-shop work, facing surfaces on shafts, plates, dies, fixtures. Precision finishing on stamped, forged or welded components in low-volume production.

Operating Procedure and Clamping System

The operating procedure is straightforward and requires no specialized CNC skills. Mount the injector nozzle on the magnetic chuck, set the digital display to zero, and use the DOWN/RISE handwheel to control grinding depth per pass.

Dual clamping system included: three-jaw chuck for irregular injector bodies and magnetic chuck for fast workpiece change-over. Operators can switch between clamping methods without retooling the machine. The compact bench-top design makes installation on any standard workshop bench straightforward.

Maintenance and Workshop Support

Routine maintenance includes grinding wheel dressing, magnetic chuck surface cleaning, and lubrication of the linear-bearing worktable. Before grinding, inspect the injector nozzle for cracks or severe wear. Mount on the magnetic chuck with the end face flat against the worktable. Set the digital display reference position to zero before starting.

All replacement parts and consumables are available from BEACON MACHINE with worldwide shipping. Custom configurations (voltage, frequency, special fixtures) are available on request. Compatible with Bosch / Denso / Delphi common rail injectors including piezo and solenoid series.
