Edge Milling Operator

Core Responsibilities

Precision Milling: Operate heavy-duty CNC edge milling machines to achieve the specified plate width and bevel profile (X-groove).

Tooling Management: Change, index, and monitor the condition of carbide milling cutters. Ensure tool wear does not exceed limits to prevent burrs or inaccurate bevel angles.

Dimensional Verification: Use specialized gauges and micrometres to verify the Bevel Angle, Root Face (Land), and Total Plate Width every few plates or as per the ITP & Work instruction.

Edge Quality Control: Inspect milled edges for surface defects, tears, or steps that could lead to weld lack-of-fusion or slag inclusions.

Material Alignment: Oversee the automated plate clamping and centring systems to ensure the plate is perfectly parallel to the milling heads.

Technical Skill Set

CNC Operation: Proficiency in HMI panels (Siemens, Fanuc, or Mitsubishi) used by machine manufacturers like Linsinger or SMS Group.

Measurement Tools: Expert use of bevel protractors and digital callipers.

Blueprint Reading: Ability to interpret Edge Preparation from process charts, WPS for different pipe thicknesses and grades (X52 to X80).

Basic Maintenance: Ability to perform daily lubrication, chip conveyor cleaning, and minor hydraulic troubleshooting.

Key Qualifications

Education: ITI (Fitter/Machinist) or Diploma in Mechanical Engineering.

Experience: 3-8 years of experience specifically in Edge Milling or large-scale CNC machining within a pipe mill (LSAW/HSAW).

Physical Stamina: Ability to manage heavy tooling changes and work in a high-noise, industrial environment on rotational shifts.

Preferred Attributes (Global Standards)

Understanding that the quality of the edge directly impacts the Ultrasonic Testing (UT) success rate after welding.

Efficient handling of steel chips/swarf for recycling and maintaining a clean work area (5S).

Strict adherence to machine guarding protocols and Lock-Out Tag-Out (LOTO) during cutter changes.
