Overview

CNC Machinist/Programmer Jobs in Benoni at Crofts Gears (Pty) Ltd

About the Role

We manufacture industrial gearboxes, couplings, and related mechanical power transmission equipment for demanding applications across a range of industries. Precision CNC machining is at the core of our production capability, and we are looking for an experienced CNC Machinist / Programmer to join our machine shop team.

This is a combined programming and operating role. You will be responsible for the full cycle — from studying engineering drawings and writing part programs, through machine setup, first-off verification, in-process inspection, and production running on 3-axis vertical machining centres and CNC turning centres. You will work to tight tolerances, maintain exacting quality standards, and actively contribute to a high-performance manufacturing environment.

We are looking for someone who takes ownership of their work, approaches problems with a can-do attitude, and is willing to put in the hours when customer requirements demand it.

Key Responsibilities: Job Planning & Process Preparation

  • Study work orders, engineering drawings, blueprints, orthographic views, and material specifications to fully understand the job before programming begins.
  • Interpret geometric dimensions and tolerances (GD&T) to determine machining strategies, reference planes, surface locations, and sequencing.
  • Select the appropriate machines, tooling, materials, and fixturing for each job, and establish efficient work procedures for new components.
  • Lay out, measure, and mark metal stock to indicate placement of cuts prior to setup.
  • Confer with engineers, supervisors, and production personnel to clarify technical requirements and exchange information before and during production.

CNC Programming

  • Write and prove CNC part programs for 3-axis vertical machining centres and CNC turning centres using FANUC controls or equivalent.
  • Enter instructions including zero and reference points, tool registers, offsets, compensation values, and conditional switches.
  • Calculate machining requirements using mathematics, geometry, and trigonometry — including gear dimensions, depths of cut, feeds, and speeds.
  • Prove out new programs on the machine, verifying that toolpaths, coordinates, and outputs meet specifications before committing to production.
  • Confer with CNC programmers and engineering to verify new programs and confirm that output will meet drawing requirements.
  • Update, adjust, and reprogram controls as required during production to optimise performance or correct deviations.
  • Evaluate machining procedures and recommend process improvements for better efficiency, repeatability, and adaptability.

Machine Setup

  • Set up mills and lathes by installing and adjusting three- and four-jaw chucks, collets, bushings, cams, gears, stops, and stock pushers as required.
  • Align and secure holding fixtures, cutting tools, attachments, and accessories on the machine — indicate vices and tram heads to specification.
  • Load stock into position using lifting equipment where required.
  • Set tool registers, offsets, feed rates, cutting speeds, depths, and angles prior to first-off production.
  • Verify machine settings by measuring positions, running first-off parts, and inspecting sample workpieces before releasing to full production.

Machining Operations & In-Process Control

  • Operate CNC turning and machining centres to produce precision metal components for gearbox, chain, and coupling assemblies to drawing specification.
  • Monitor feed rates, cutting speeds, and machine behaviour continuously during production — observe, listen, and respond to any changes in machine sound or performance.
  • Perform turning, facing, boring, grooving, knurling, thread chasing, milling, and drilling operations as required by the job.
  • Ensure workpieces are correctly lubricated and cooled throughout the machining process.
  • Detect and troubleshoot malfunctions, process deviations, and tooling wear — take corrective action promptly to prevent scrap.
  • Sharpen and replace worn tooling in accordance with the tooling schedule and as machining conditions require.

Quality & Inspection

  • Calculate and verify component dimensions and tolerances using micrometres, vernier callipers, dial gauges, and other precision instruments.
  • Inspect first-off and in-process components to detect defects and confirm conformance to drawing specifications and GD&T requirements.
  • Adhere to all quality assurance procedures and company quality standards — minimum product quality is non-negotiable.
  • Complete production and quality logs accurately for every job — records must be current and correct.
  • Record labour hours in the time management system accurately and on time.

Machine Care & Maintenance

  • Complete scheduled preventive maintenance in accordance with manufacturer’s instructions and the machine maintenance programme.
  • Clean and lubricate machines, tooling, and equipment regularly to remove swarf, grease, rust, and foreign matter.
  • Diagnose machine malfunctions by observing performance and listening to operating sounds — log faults and call for repairs when required.
  • Install repaired or replacement parts and verify operational efficiency following maintenance or repair work.
  • Maintain machines, tooling, and the work area in a consistently clean and orderly condition — good housekeeping is an expected standard.

Knowledge Sharing & Mentoring

  • Take an active role in the training and development of apprentices and less experienced machinists — share programming techniques, setup methods, and inspection practices on the job.
  • Provide structured guidance to junior team members on machine operation, tooling selection, and process discipline, helping to build a stronger machine shop capability over time.
  • Support the transfer of CNC programming knowledge within the team — document programs, settings, and processes clearly so that knowledge is retained and accessible.
  • Model the standards you expect of others: precision, housekeeping, safety compliance, and ownership of quality.

Collaboration & Continuous Improvement

  • Work closely with engineers, supervisors, fitters, and fellow machinists — communicate clearly and proactively to keep production flowing.
  • Support metalworking projects from initial planning and fabrication through to assembly, inspection, and testing.
  • Actively explore opportunities to add value, improve processes, and solve problems — accept ownership of new challenges as they arise.
  • Participate in training and development opportunities to keep technical knowledge and programming skills current.
  • Carry out additional duties as reasonably required by the supervisor or management.

Health, Safety & Environment

  • Work in full compliance with the Occupational Health and Safety Act (OHSA) and all applicable machine shop safety requirements.
  • Promote and maintain environmental awareness in all activities — responsible handling of coolants, lubricants, swarf, and waste is expected.
  • Use personal protective equipment correctly and consistently — this is non-negotiable in a CNC machining environment.
  • Ensure all machine guards and safety interlocks are in place and functioning before operating any equipment.
  • Report hazards, near-misses, and unsafe conditions to the supervisor immediately.
  • Contribute to a safe working environment for yourself and your colleagues at all times.

What We Are Looking For: Qualifications & Experience

  • CNC Programming qualification at NQF Level 4 — essential.
  • 3 to 5 years of proven experience as a CNC machinist/programmer in a precision manufacturing environment.
  • Hands-on experience programming and operating CNC turning centres and 3-axis vertical machining centres.
  • FANUC control experience is strongly preferred; other equivalent CNC control systems will be considered.
  • Proficient in reading and interpreting engineering drawings, blueprints, and GD&T.
  • Strong mathematical ability — comfortable applying geometry and trigonometry to real machining problems.
  • Competent with precision measurement instruments: micrometres, vernier callipers, dial gauges, and bore gauges.
  • Experience machining components for gearboxes, power transmission equipment, or similar precision assemblies is advantageous.
  • Prior experience training or mentoring apprentices or junior machinists is an advantage.

The Person

  • Technically capable across the full CNC cycle — programming, setup, operation, and inspection — without requiring hand-holding.
  • A practical problem-solver who identifies solutions under pressure rather than waiting for direction.
  • Precise, methodical, and consistent — you produce the same quality at the end of the week as you do at the start.
  • Takes ownership of quality, machine condition, and workspace standards.
  • A clear and constructive communicator — you raise issues early and work with the team to resolve them.
  • Willing to work additional hours when customer deadlines require it — delivery matters.
  • Positive, adaptable, and open to continuous improvement in process and practice.
  • Willing to share knowledge generously — you see the development of junior colleagues as part of your role, not a distraction from it.
  • Honest, reliable, and aligned to high standards of professional conduct.
