01 / APPROACHDesign meets reality

Manufacturing is where the design becomes accountable

A model can describe the ideal part. Manufacturing has to resolve access, workholding, material behavior, tool paths, joining, assembly, leak integrity, finish requirements, and repeatability. ERC Concepts Co. brings CNC lathe work, vertical and horizontal CNC milling, precision assembly, TIG welding, silver brazing, and vacuum leak detection into one practical manufacturing conversation.

See how ERC approaches the work
01

Review

Understand the drawing, model, interfaces, quantities, and critical requirements.

02

Plan

Resolve material, workholding, machining, joining, assembly, and verification needs.

03

Machine

Apply the appropriate CNC lathe, vertical mill, or horizontal mill path to the part.

04

Complete

Coordinate defined assembly, joining, leak detection, finishing, and delivery requirements.

02 / CAPABILITYSelect a discipline

Not a machine list.
A path through the part.

ERC's broadcast services span CNC lathe work, vertical and horizontal CNC milling, precision assembly, TIG welding, silver brazing, vacuum leak detection, and prototype and production runs. The path still starts with the complete part.

Featured manufacturing capability

CNC milling

Prismatic components, faces, pockets, bores, and intersecting features planned around access and workholding.

Milling strategy is reviewed against geometry, datum relationships, material, and the number of setups a part may require.

03 / QUALITYThe standard starts early

Quality starts before the first cut.

A finished dimension is the result of decisions made across review, planning, machining, verification, and communication.

01Define what mattersDrawing, datums, revisions, finish, and acceptance criteria.
02Plan for repeatabilityControlled inputs, intentional setups, and stable methods.
03Verify the agreementInspection aligned to the drawing and project scope.

05 / PROGRAM FITBuild for what comes next

One-off challenge or repeat requirement

The right production approach depends on what the program needs now and what it may need next—from one prototype through production runs. We structure the conversation around development stage, geometry, machining, assembly, joining, leak detection requirements, quantities, downstream operations, and the information required for repeat work.

What to include in an RFQ
  1. 01
    DevelopmentClarify design intent and manufacturing constraints.
  2. 02
    PrototypeCreate physical feedback for fit, assembly, and function.
  3. 03
    RefinementResolve revisions and establish a stable process.
  4. 04
    Production runsMaintain clear inputs and a consistent manufacturing path for repeat work.

06 / APPLICATIONSBuilt for physical systems

Where engineered ideas
become working hardware.

ERC's machining approach may be applicable wherever engineered components must locate, carry, align, connect, seal, or protect.

01Semiconductor equipment

Machined components can support tooling, motion, handling, thermal, vacuum, and equipment development challenges.

02Robotics & automation

Brackets, interfaces, housings, fixtures, and motion system components turn control systems into physical machines.

03Instrumentation

Mechanical structures and interfaces help sensing, optics, test, and measurement systems perform as intended.

04Hardware development

Prototype and iterative machined parts help product teams validate form, fit, function, and assembly decisions.
