CNC Machining Technician II - 2nd Shift

Bond Optics•Lebanon, NH

2d•$26 - $33•Onsite

About The Position

Bond Optics is seeking an experienced CNC Machining Technician II to independently set up, operate, and optimize CNC machining centers for precision operations on optical and ceramic components used in demanding defense, aerospace, and industrial applications. This role is ideal for a skilled CNC machinist who can work with non-metallic materials (glass, ceramics, crystalline substrates), interpret drawings, write and edit G-code programs, troubleshoot process issues, and maintain tight dimensional tolerances. The CNC Machining Technician II also mentors Technician I personnel and contributes to process improvement. Equipment Scope: This role operates conventional CNC machining centers (HAAS, Mori Seiki, or equivalent) configured for glass and ceramic material processing. This is not a traditional metal-cutting machining position.

Requirements

High school diploma or equivalent.
3+ years of CNC machining experience, preferably with non-metallic materials (glass, ceramics, or similar brittle substrates).
Proficiency in CNC machine setup, operation, and basic troubleshooting on HAAS, Mori Seiki, or equivalent machining centers.
Working knowledge of G-code programming, including the ability to write, read, edit, and verify programs.
Ability to read and interpret machining drawings, blueprints, and specifications.
Proficient shop math skills including algebra, geometry, trigonometry, fractions, ratios, and decimal arithmetic.
Strong skills in dimensional measurement using precision inspection tools.
Strong attention to detail, documentation discipline, and process consistency.
Good communication and teamwork skills.

Nice To Haves

Experience machining optical glass, technical ceramics, or crystalline materials.
Experience with diamond tooling selection and management for brittle material machining.
Familiarity with coolant systems, filtration, and waste management for glass/ceramic machining.
Experience with CAM software for toolpath generation.
Familiarity with shop-floor software, ERP/MRP systems, and production data systems.
Experience in aerospace, defense, semiconductor, or other high-spec manufacturing environments.
Familiarity with GD&T (Geometric Dimensioning and Tolerancing) principles.

Responsibilities

Independently set up, operate, and optimize CNC machining centers (HAAS, Mori Seiki, or equivalent) for precision operations on glass, ceramic, and crystalline substrates including: Edging and diameter generation to tight tolerances
Beveling, chamfering, and edge profiling
Profile machining, contouring, and specialty material removal operations
Select, mount, and qualify tooling (diamond grinding wheels, cutting tools, fixtures) appropriate for the material and operation.
Read and interpret machining drawings, optical drawings, work travelers (manufacturing routing documents), and specifications.
Write, edit, and verify G-code programs; make in-process program adjustments to optimize cycle time, surface finish, and dimensional accuracy.
Perform in-process and final dimensional inspection using precision metrology tools including: Micrometers, calipers, and electronic/dial indicators
Optical comparators
Height gauges and bore gauges
Surface finish gauges and edge inspection tools
Monitor tool wear, chipping, and breakage; manage tool life and replacement schedules.
Troubleshoot machining issues including chatter, runout, thermal drift, chipping, and breakage on brittle substrates; identify root causes and implement corrective actions.
Maintain process records, job logs, labels, and traceability documentation using shop-floor systems.
Perform routine machine maintenance including coolant management, way lubrication, spindle checks, and fixture upkeep; support preventive maintenance schedules.
Work with supervisors, quality, and engineering to resolve process or quality issues and support new part introduction.
Mentor and train CNC Machining Technician I personnel on setup standards, safe machine operation, workmanship expectations, and documentation practices.
Contribute to continuous improvement initiatives to improve yield, cycle time, tool life, and process repeatability.
