Job Description

Accountability:

Performs a wide range of duties to set-up, adjust and operate precision grinding machines (ID / OD / Surface Grinders). Grinds internal and external surfaces to close and exacting tolerances which involve several interrelated dimensions. Grind parts to required finish on work having steps or surfaces, high precision diameters, recesses and tapers. This requires skill, judgment and knowledge related to precision grinding techniques and finishes. Have some knowledge of GDOT. Be able to read Blueprints.

Scope and Responsibilities:

Essential duties include, but are not limited to the following:

• Plans a sequence of standard and recognized operations.
• Makes set-ups and adjustments on special and difficult work.
• Plans grinding sequence, selects speeds, feeds, wheels and holding devices.

• Positions, aligns and secures workpiece in machine, set grinding head to conform with specifications, making required adjustments and grinding parts of various styles and sizes. For example: spindles, spindle sleeves, rams and housings and bushings.
• Starts and observes machine operation to detect malfunctions or out-of-tolerance machining and adjusts machine controls or control media as required.
• Studies and works from part drawings, specifications, charts, etc. (on a variety of steels, alloys and castings) to determine dimensions and tolerances of finished workpiece. Works to very close tolerances.
• Uses a range of measuring instruments such as scales, square, calipers, micrometers, verniers, indicators, air gauges, special fixed and adjustable measuring devices to make set-ups, adjustments and to check work.
• Detects unusual conditions, defective materials or operating difficulties and report to proper supervision. Maintains machine and work area in a clean and orderly manner.
• Provides training and technical support to other employees within the grinding department, as required.
