Advanced Internal and External Grinding Operations Training

Learning Outcomes

• Apply advanced grinding techniques to produce complex internal and external profiles within specified tolerances.
• Select and set up appropriate grinding wheels, coolants, and work-holding devices for complex operations.
• Evaluate workpiece quality using precision measuring instruments and adjust processes to meet specifications.
• Demonstrate adherence to safety protocols and maintain grinding equipment for optimal performance.
• Analyze grinding parameters to optimize cycle times and surface finish quality.
• Implement corrective actions for common grinding defects such as burns, chatter, or dimensional errors.

Target Audience

Experienced machinists, toolmakers, and production technicians who require advanced grinding competencies to handle complex workpieces and tight tolerances.

Prerequisites

None — open enrollment

Course Outline

Practicals

Overview

Hands-on practical sessions are integral to this course, allowing learners to apply theoretical knowledge in a supervised workshop environment. Learners will set up and operate cylindrical, internal, surface, and centerless grinders, producing components to tight tolerances. These sessions reinforce safe work practices, precision measurement, and troubleshooting skills.

Practical Activities

• External Cylindrical Grinding Practical — Learners set up a cylindrical grinder, select and dress a grinding wheel, and grind a stepped shaft to within ±0.01 mm tolerance and surface finish Ra 0.4 μm. (12h)
• Internal Grinding Practical — Learners mount an internal grinding spindle, select a suitable wheel, and grind a bore to specified roundness and size within ±0.005 mm. (12h)
• Surface Grinding Practical — Learners set up a surface grinder with a magnetic chuck, grind a steel block to flatness within 0.005 mm and surface finish Ra 0.2 μm. (10h)
• Centerless Grinding Practical — Learners set up a centerless grinder for through-feed grinding of cylindrical pins, achieving diameter tolerance ±0.01 mm and roundness within 0.002 mm. (8h)
• Integrated Assessment Practical — Learners complete a combined task: grind an internal bore and external diameter on a single workpiece, inspect all dimensions, and submit a quality report. (6h)

Summatives

Each delegate is assessed continuously throughout the course via daily exercises, scored practical assignments, and a final summative test at the end.

Practical Assignments — 30%

Practical assignments are observed and scored against a rubric during the practical sessions. Each delegate's practical mark is averaged into a single 100% score and contributes 30% to the final total.

Daily Exercises — 20%

Every training day ends with a multiple-choice exercise scored out of 100%. The scores from each daily exercise are averaged across the duration of the course to produce a Daily Average mark, which contributes 20% to the final total.

Final Test — 50%

On the last day a final summative test is written. It is a multiple-choice paper with multiple-answer questions: each question may have more than one correct option, and a single wrong selection on a question marks the entire question wrong — no partial credit. The final test is scored out of 100% and contributes 50% to the overall mark.

Final Total

Component	Out of	Weight
Practical Assignments (rubric-scored)	100%	30%
Daily Average (multiple choice)	100%	20%
Final Test (multi-answer multiple choice)	100%	50%
Final Total	—	100%

All marks are recorded on the AATICD LMS and visible to each learner under their account.

Certificate

How it works

• Certificates are auto-generated on the AATICD LMS as soon as the marks pass the 50% threshold.
• Each certificate is a branded PDF with the delegate's name, the course title, the unit standard ID, NQF level, credits, and the date of issue.
• You can download or print your certificate from your LMS dashboard at any time after issue — there's no reissue fee and no expiry date.
• If you scored under 50% you can sit the final test again at the next scheduled session at no extra cost.

Where to find it

Sign in to the LMS, open your dashboard, and your certificates appear under My Certificates. Each entry has a View / Download button and a print option.
