Core Responsibilities

Primary Functions

Operate a variety of glass grinding and polishing machines, including hand-held grinders, belt sanders, and automated CNC edging equipment to shape and finish glass products.
Carefully interpret complex blueprints, work orders, and technical specifications to determine the exact grinding, beveling, and finishing requirements for each piece of glass.
Accurately set up and calibrate grinding machinery by adjusting guides, stops, wheel positions, and program parameters according to the specified dimensions and angles.
Select the appropriate grinding wheels, polishing belts, and cerium compounds based on the glass type, thickness, and the desired edge finish (e.g., pencil polish, flat polish, ogee).
Skillfully handle and position large, heavy, and often fragile glass sheets onto machine beds or worktables, frequently utilizing suction cup lifters and other material handling aids.
Perform high-precision grinding, seaming, beveling, and polishing on the edges of flat glass, mirrors, and custom components to achieve a perfectly smooth, defect-free finish.
Conduct rigorous in-process and final quality control checks using precision measuring instruments such as digital calipers, micrometers, and protractors to verify all dimensions and tolerances.
Visually inspect all glass surfaces and edges for scratches, chips, swirls, and other imperfections, meticulously marking and segregating defective pieces for rework or disposal.
Execute routine preventative maintenance and cleaning on all grinding equipment, including changing and dressing grinding wheels, checking coolant levels, and lubricating moving parts.
Maintain a clean, organized, and hazard-free work area, strictly adhering to all company and OSHA safety protocols, including the consistent use of personal protective equipment (PPE).
Closely monitor machine operations during cycles, listening for unusual noises and observing performance to preemptively identify potential malfunctions or the need for fine-tuned adjustments.
Precisely document daily production data, including the number of pieces completed, cycle times, material scrap, and any downtime, using company logbooks or digital tracking systems.
Grind, shape, and finish custom or specialty glass pieces for unique applications, which requires a high degree of manual skill, artistic judgment, and problem-solving.
Perform both wet and dry grinding processes, demonstrating a full understanding of the different techniques, equipment, and safety precautions required for each method.
Deburr and smooth the rough, sharp edges of freshly cut glass to ensure it is safe for handling and processing in subsequent production stages like tempering or laminating.

Secondary Functions

Collaborate with the cutting, tempering, and laminating departments to ensure a smooth, efficient workflow and to troubleshoot any inter-departmental quality issues.
Assist in managing and maintaining an inventory of grinding consumables, such as wheels, belts, and coolants, and proactively notify supervisors when new materials need to be ordered.
Prepare and carefully package finished glass products for storage or shipment, ensuring they are adequately protected to prevent breakage or surface damage during transit.
Participate actively in daily team meetings and huddles to discuss production goals, safety topics, and any challenges from the previous shift.
Contribute to continuous improvement initiatives by providing practical feedback and suggestions on how to enhance safety, quality, and efficiency within the grinding department.
