Machinists use machine tools, such as lathes and milling machines
to produce precision metal parts that meet or exceed the tolerance
requirements found in today's marketplace. Skilled machinists possess
both the knowledge of metal properties and the ability to setup
and operate complex machine tools.

Many of today's machine tools are computer numerically
controlled (CNC) machine tools. The introduction of CNC machine
tools has changed the nature of machining work. CNC machines enable
machinists to be more productive and to achieve a level of precision
not possible with traditional machines. Software files record precise
CNC machine movements.These files produce efficiency in the workplace
because they allow operations to be consistently and easily repeated.

At Dura-Metal Products Corporation, journeyperson
machinists, tool & die makers and apprentices perform three distinct
work phases: (1) Operation Planning (2) Execution and (3) In-Process
Inspection
Operation Planning includes:
- Careful review of process plans, blueprints and written job specifications.
- Selection of the correct materials and tools for the job.
- Calculation of cut or bore locations, feeds, speeds, and metal removal
rates.
- Correctly sequencing the cutting operations.
Execution includes:
-
Positioning the metal stock on the machine
tool.Setting machine controls
-
Performing the machining operation, either
by CNC or manual means.
- Monitoring the adequacy of machine feed and speed.
- Ensuring proper lubrication and cooling.
In-Process Inspection includes:
- Verification of all dimensions for every component.
- Operator documentation of results.
- Dura-Metal's skilled journeypersons incorporate a combination of CNC
and conventional equipment to satisfy your precision machining needs.
