1st Shift ACME Multi-Spindle Machine Operator

Description

Job Title: Multi-Spindle Screw Machine Operator

Department: Production

Reports To: Production Supervisor & Machining Manager

FLSA Status: Non-Exempt

Blueprints/Print Reading:

• Read basic prints: title block, simple dimensions, +- tolerances.
• Identify basic features (radius, chamfer, thread notes).
• Understand part orientation and match-up with sample parts.

Gauging:

• Use calipers, 0-1” micrometers, go/no-go gauges, thread plug/ring gauges.
• Perform visual checks for burrs, surface finish, and part completeness.
• Record results on check sheets and follow stop-and-notify rules.

Core Responsibilities:

• Load bar stock on blanks and unload completed parts.
• Monitor machine cycle, feed, and part pickoff.
• Identify abnormal sounds or vibration and alert setup/maintenance.
• Maintain clean, 5-S-compliant work area.

Basic Maintenance:

• Clean chips and oil buildup; wipe down machine.
• Empty chip pans/trays.
• Check coolant/oil levels and refill as trained.
• Report leaks or irregular machine behavior immediately.

Blueprints/Print Reading:

• Read more detailed prints including section views and detail callouts.
• Understand basic GD&T (true position, concentricity, runout).
• Identify critical-to-quality dimensions and tolerances.

Gauging:

• Use micrometers, snap gauges, dial bore gages, depth gages, optical comparator (basic checks).
• Know how to master gauges and check for repeatability.
• Record SPC data and respond to out-of-control trends as instructed.

Core Responsibilities:

• Operate multiple multi-spindle machines independently.
• Make minor adjustments (feeds/speeds, cam followers tension, collet tension).
• Change inserts, reamers, taps, drills, and other standard tooling.
• Follow control plans, inspection frequencies, and tagging procedures.

Basic Maintenance:

• Perform daily/weekly operator PM (lubrication checks, coolant checks, chip removal).
• Clean and re-seat collets and checking areas.
• Replace basic wear items (inserts, springs, simple guides).
• Assist setup or maintenance with simple tasks.

Blueprints/Print Reading:

• Read complex prints and understand tolerance stack-ups.
• Apply GD&T to setup; datums, MMC/LMC, feature control frames.
• Use prints to determine tooling layout, station order, and critical operations.

Gauging:

• Proficient in:
  Dial bore gages with mastering, air gages, indicator stands & surface plate inspections, optical comparator overlays.
• Perform first-piece layout and verify critical dimensions.
• Correlate in-process gauging with CMM reports (when available).

Core Responsibilities:

• Perform complete setups on multi-spindle screw machines.
• Set cams, gears, attachments (shave tools, roller boxes, slotting, threading).
• Adjust pickoff timing, bar feed, and cross-slide operations.
• Troubleshoot size issues, chatter, chip control, and finish problems.
• Create/update setup sheets and tooling documentation.

Basic Maintenance:

• Swap/align collets, pads, feed fingers, and supports.
• Replace belts, simple timing adjustments, and lubrication line checks.
• Clean coolant systems, strainers, and chip conveyors.
• Inspect cam followers, clutches, and indexing components; report wear.

Blueprints/Print Reading:

• Perform detailed tolerance analysis for setup planning.
• Interpret complex GD&T including profile, perpendicularity, and runout control.
• Work with engineering on print interpretation and manufacturability issues.

Gauging:

• Lead gauge selection for new jobs.
• Proficient with air-gage fixtures, multi-diameter bore gaging, indicator tramming setups.
• Conduct gage R&R reviews for key characteristics.
• Train other operators in correct gauge handling.

Core Responsibilities:

• Setup complex parts requiring tight tolerances, multi-operation timing, or specialty attachments.
• Optimize feeds, speeds, cam designs, and tool geometries.
• Lead root-cause analysis and corrective actions for scrap or downtime.
• Support engineering on tooling design and continuous improvement.
• Train Level I-III operators.

Basic Maintenance:

• Perform alignment checks; spindle runout, slide alignment, cross-slide squareness.
• Replace pumps, coolant…
