PCC is relentless in its dedication to being a high-quality, low-cost and on-time producer; delivering the highest value to its customers while continually pursuing strategic, profitable growth.

In 2016, Berkshire Hathaway, led by Chairman and CEO Warren E. Buffett, acquired Precision Castparts Corp.

Position Summary:

The Centerless Grinder “A , sets up and operates one or more centerless grinding machines to grind external or internal cylindrical or tapered surfaces of metal work pieces to blueprint specifications, following tooling instructions and standard charts and applying knowledge of grinding procedures. Reads blueprint and job order for product specifications, such as dimensions, tolerances, and number of parts to be ground, and tooling instructions, such as grinding speeds, feed rates, holding fixtures, and grinding wheels to be used.

Primary Duties & Responsibilities:

• Positions and secures work rest at specified height, using wrenches.
• Perform advance machine maintenance and troubleshoot problems.
• Lift and positions work-piece manually or with hoist, and secures it between wheels and on work rest.
• Reference speeds and feeds charts and calculate the appropriate settings to maximize equipment capability.
• Moves controls to set specified grinding speeds, feed rates, and spacing between wheel faces.
• Changes worn grinding wheels, using wrenches. May set up automatic work feeding device.
• Analyze best grinding method, given work material. Mounts grinding wheel and regulating wheel on spindles with wrenches.
• Set up centerless grinding machine to produce parts according to set up sheets and router requirements.
• Starts machines and observes operation. Verifies dimension of ground work-piece for conformance to specifications, using measuring instruments, such as micrometers, calipers and preset gauges.

Required Skills and Experience:

• Must be capable of working effectively with minimal direction and supervision.
• Inspect first article and maintain quality during production of lot.
• Check condition of grinding wheels.
• Set guide rail, adjust wheel to size and set stop length.
• Blueprint Reading & Interpretation – Demonstrate the ability to reliably read and interpret the following: drawing terms; call outs; symbols and/or descriptions; types of lines; front view; side view; top view; section view; types of radii; tolerances (min. and max.); external/internal thread; surface finish; fastener-related specifications.
• Attention to detail and an attitude of 100% compliance with all company and regulatory requirements.
• Monitor machine for proper operation, lubrication and coolant level.
• High energy level and ability to work flexible hours.
• Communication – Demonstrate the ability to communicate effectively with team members to achieve cooperation and assistance needed to resolve problems and attain maximum productivity.
• Minimum five year experience in the operation of centerless grinding machines.
• Mathematical Skill – Must have basic Mathematical skills such as Add, subtract, multiply, and divide whole numbers, fractions, and decimals. Measure lengths and distances and calculate areas, volumes, and weights. Able to compute rate, ratio and percentage.
• Workmanship – Demonstrate the ability to identify and take appropriate action to prevent, correct, or reject the following conditions on die and tools parts: cracks; nicks, scratches and dents.
• Maintain a clean and safe work area.
• Ability to read blue prints, inspect pars and obtain reference information from detail prints.
• Basic Visual & Dimensional Inspection – Demonstrate the ability to inspect parts reliably using the following tools: caliper (dial and digital); micrometer (stand, blade, and disk); dial drop indicator; test indicator; comparator; pin gage; gage block set; any functional gages applicable to the operator. Must have the ability to use hand tools and measuring instruments
• Train less experienced operators.
• Ability to work in a team-oriented environment.

Desired Skills:

• Ability to apply common sense understanding to carry out instructions furnished in written, oral, or diagram form. Ability to deal with problems involving several concrete variables in standardized situations.
• Ability to read and interpret documents such as safety rules, operating and maintenance instructions, blueprints and procedure manuals as well to write routine data on routers and company charts.
• Self-motivated individual who can work independently as well as work effectively in a collaborative team environment.

& Education

• High School Diploma.
