Machinists are industrial experts who utilize machinery tools to create or change parts based on specifications indicated in technical drawings that serve as their blueprints. To polish and achieve the desired shape of the part, they have to be skilled in using machines used for drilling, cutting, grinding, lathing, and other relevant procedures. Machinists generally use electric-powered tools but there are also instances when manual hand tools must be used.
Types of Machinists
Machinists can be categorized into different types depending on where they focus in their work.
1. Precision Machinists
These machinists make machined products that have precision requirements such as bolts and pistons. Precision machinists must have sufficient knowledge in the working properties of metal elements such as aluminum, steel, and titanium as well as the machine tools they need for their operation.
Before a precision machinist executes the operation of making a specific part, he has to review the technical drawing first and then analyze the details and calculate the speed of feeding the metal piece into the machine. Less frequently, machinists also make plastic and wooden parts. Most of the time, precision machinists produce items in small quantities and customized parts.
2. Production Machinists
Production Machinists produce parts in bulks or volume. For this production, modern machine equipment called Computer Numerically Controlled (CNC) machines has to be used. CNC machines use computer-controlled operations to perform the necessary steps of creating parts such as cutting, drilling, and polishing. Production machinists also frequently work with computer control programmers who assist them with computer operations. However, many machinists nowadays are already trained in CNC programming so they can employ manual and computer-controlled machine tools to perform their work.
3. Maintenance Machinists
Generally, maintenance machinists are in charge of creating parts for existing machinery or repairing broken parts. Usually, maintenance machinists receive work from mechanics who hand them broken machine parts to fix. The job of maintenance machinists is not at all easy as they have to be familiar with the operations of the machine for which the part belongs and make the necessary repairs and adjustments as necessary. You can find maintenance machinists in more industrial settings than other machinists as basically all machines need repairs and maintenance from time to time.
There is no shortage of machinist jobs are in demand in industrial companies. However, because of the highly technical nature of the job, employers tend to hire machinists that possess advanced relevant skills. So if you are a machinist, it is important to constantly update your skills and receive further training to add to your credentials.
