Description
We're looking for an experienced CNC Lathe Machinist capable of machining compressor valves, components and machining / manufacturing precision parts such as pistons, pins, and rods. The machinist must be comfortable setting up and operating CNC lathes independently while maintaining tight tolerances and high-quality finishes.
Core Responsibilities
- Repair and machine compressor valve components, including CPP valve seating surfaces used in compressors manufactured by Ariel Corporation.
- Maintain tight dimensional tolerances and high surface finish standards.
- Set up and operate CNC lathes equipped with Fanuc CNC controls.
Requirements
CNC Programming Knowledge
- Ability to read and edit G-code programs.
- Ability to read blueprints.
- Understand tool paths and anticipate the next movement of the machine before executing a program.
- Ability to run programs provided by the programmer and safely verify the machining process.
Machine Setup & Operation
- Touch off cutting tools and correctly set tool offsets.
- Understand and correctly use work offsets.
- Experience setting up parts and ensuring proper alignment before machining.
- Ability to cut and bore soft jaws to properly hold parts.
- Experience using a hydraulic tailstock to support longer parts and maintain stability during machining.
Precision Machining Requirements
- Ability to hold ±0.005" tolerances or tighter when required by print.
- Maintain runout within ±0.001" when indicating parts.
- Machine precision features such as:
o Piston outside diameters
o Ring grooves
o Valve seating areas
o Threaded studs
Inspection & Measurement
- Experience using precision measuring tools including:
o Micrometers
o Dial indicators
o Bore gauges
o Height gauges with ball gauges for accurately measuring seating areas
- Ability to verify part dimensions during machining to ensure prints are met.
Machining Knowledge
- Strong understanding of speeds and feeds for various materials.
- Ability to adjust cutting parameters to achieve:
o Proper surface finish
o Dimensional accuracy
o Efficient tool life
- Experience machining alloy steels and other materials commonly used in compressor components.
