Operator Centerless Grinder Apprenticeship Course Syllabus

Course Title

Operator Centerless Grinder Apprenticeship Course

Course Code

OCG101

Description

This course, under the Apprenticeship Training Scheme (ATS), provides comprehensive training for centerless grinder operators, focusing on setting up, operating, and maintaining centerless grinding machines to produce precision parts. Apprentices will gain hands-on experience in throughfeed, infeed, and endfeed grinding, interpreting blueprints, and ensuring quality control, preparing them for roles in automotive, aerospace, and tool manufacturing industries. The course aligns with the National Apprenticeship Promotion Scheme (NAPS) and complies with the Apprentices Act, 1961.

Objectives

  • Set up and operate centerless grinding machines to grind external cylindrical surfaces to precise specifications.
  • Interpret technical drawings and use measuring instruments like micrometers and calipers for quality assurance.
  • Perform preventive maintenance and troubleshoot common issues in centerless grinding operations.
  • Adhere to safety protocols and industry standards during grinding operations.

Schedule

The course spans 8 weeks, combining basic training and on-the-job practical training as per ATS guidelines. Each week focuses on specific skills essential for centerless grinder operators. Below is the detailed breakdown:

Week 1: Introduction to Centerless Grinding

Overview of centerless grinding, operator roles, machine components (e.g., grinding wheel, regulating wheel, work rest blade), and workplace safety under ATS.

Week 2: Machine Setup and Components

Setting up centerless grinders, adjusting work rest blades, and mounting grinding and regulating wheels for throughfeed, infeed, and endfeed operations.

Week 7: Safety and Compliance

Implementing OSHA safety standards, handling hazardous materials, and ensuring compliance with industry regulations.

Week 8: Final Project and Assessment

Completion of a comprehensive centerless grinding project (e.g., producing a precision part to specifications) and preparation for the All India Trade Test (AITT) under NCVT.

Assessment Methods

Apprentice performance is evaluated through a combination of practical, theoretical, and participatory components, preparing them for the National Apprenticeship Certificate (NAC):

  • Weekly Assignments: 40%
  • Midterm Project: 20%
  • Final Project: 30%
  • Participation and Attendance: 10%

Additional Notes

Apprentices must be at least 14 years old and meet the minimum educational qualification (typically 10th grade passed or equivalent, preferably with a science or technical background, as per trade requirements). The course includes basic training (20-25% of the program) and on-the-job training, with a stipend provided as per NAPS guidelines (e.g., Rs. 7700 per month for one-year ITI trade passed apprentices, as per Gazette notification dated 25th September 2019). Successful completion leads to the National Apprenticeship Certificate (NAC) upon passing the All India Trade Test (AITT), recognized for employment in government and private sectors. The training emphasizes precision grinding skills, such as operating Cincinnati or Royal Master centerless grinders, and safety, addressing the demand for skilled operators in India’s advanced manufacturing sectors.
