7 Cons of Being a CNC Machinist

We’ve taken a look at some of the most promising aspects of working as a certified CNC machinist.

Now that you have an idea of the positive aspects of working as a CNC machinist, let’s look at some of the cons for a balanced perspective on this highly challenging role.

Con #1. – High Stress

While there are tons of upsides to working as a certified CNC machinist, this high-paying career also presents a few downsides, with high stress levels making the top of the list.

Meeting production deadlines, troubleshooting production issues, and maintaining quality standards are just a few stress-inducing factors affecting today’s increasingly frustrated machinists at work.

Having to interrupt work mid-production to troubleshoot or recalibrate malfunctioning CNC machines can add to high-stress levels.

Con #2. – Shift Work Leaves Some Machinists Feeling Sluggish

Machinists have to meet the production requirements to meet product demand and manufacturing schedules that help keep logistics providers and shipments on time.

CNC machinists may be required to work long or irregular hours in manufacturing centers.

Irregular work schedules and shift work are often tailored to meet industry production needs.

Taking on a shift-work-based career can result in working shifts that begin in the middle of the day, late at night, or in the wee hours of the morning. 

Con #3. – Technical Challenges Can Slow Down Productivity

The nature of the work of the CNC machinists means that technical challenges will inevitably arise.

This can be another downside for highly stressed machinists as they work diligently to repair downed equipment to keep manufacturing and logistics projects on track.

Technicians can spend precious manufacturing and production time on diagnosing and repairing CNC machines.

Common repairs can include retooling or reprogramming machines that can drastically impact production.

Con #4. – Limited Creativity Can Lead to Frustration or Boredom

The role of a CNC machinist is based on repetitive manufacturing processes and strict adherence to production and quality standards.

Some CNC machinists working in industries where the products are relatively the same and the standards set in stone may run into boredom as they experience the negative effects of limited creativity.

Complex production and manufacturing standards have little room for deviation and must be followed to the letter to prevent production issues or product quality issues.

Con #5. – Monotonous Tasks Can Drive Job Dissatisfaction

There is little wiggle room for CNC techs to carry out manufacturing tasks according to computer-generated instructions and blueprints

CNC operators can experience a lasting sense of boredom from a lack of creativity in fabricating metal and plastic parts and components.

Carrying out repetitive motions and machine operations for routine tasks can lead to lower job satisfaction for technicians seeking a wider variety of job tasks to bolster their creativity.

Con #6. – Job Safety Risks Are a Reality

The role of a CNC operator comes along with job safety risks based on working with high-tech machines in manufacturing environments.

Power tools and machining equipment required to manufacture specific parts can impose safety risks for technicians who don’t follow safety protocols and precautions to the letter.

Con #7. – Mentally / Physically Demanding Role

CNC machinists carry out mentally and physically demanding tasks that require them to stand for prolonged periods, lift and move heavy materials, and carry out repetitive motions that can lead to physical strain or fatigue when technicians become mentally overtaxed from high levels of stress or work interruption when technicians suffer from repetitive motion injuries.
