Precision CNC Machining,Built to Your Drawing.
HIQ Precision provides precision CNC machining for custom components, castings and assemblies from prototype through repeat production. We begin by reviewing the drawing, material, tolerance and quantity to define a practical machining route.

Precision CNC Machining Capabilities
Every feature, datum and tolerance affects the machining plan. Therefore, our engineering team connects programming, workholding, tooling and inspection before production begins.
01 / MILLING
CNC Milling
Primarily, we program pockets, faces, profiles and complex features around datums and tolerance requirements.
02 / TURNING
CNC Turning
In addition, precision CNC machining of shafts, bushings, fittings and round parts can include secondary milling and drilling.
03 / COMPLEX PARTS
Multi-Axis Work
Then we plan complex geometries and multi-sided features for accuracy and efficient setups.
04 / VOLUME
Prototype to Production
One-off prototypes and repeat orders follow a documented machining and quality plan.
05 / FINISH
Secondary Operations
Finally, secondary operations stay coordinated with machining, surface treatment, heat treatment and assembly.
06 / INSPECTION
CMM & Quality
Critical dimensions and documentation are checked against the approved drawing and plan.
How we work
From Quote to Precision CNC Machining Delivery
In practice, a clear precision CNC machining process keeps technical assumptions visible. In addition, each approval creates a baseline for repeat production and inspection.
01 / REVIEW
Drawing Review
First, confirm materials, tolerances, datums and critical features.
02 / PLAN
Process Planning
Next, select machines, workholding, tools and inspection methods.
03 / MACHINE
CNC Production
Then program, set up and machine with in-process checks.
04 / VERIFY
Dimensional Review
After machining, verify critical characteristics against the drawing.
05 / DELIVER
Finish & Deliver
Finally, complete secondary operations, packing and delivery.
Materials & planning
Precision CNC Machining: Materials & Planning
Material, heat treatment and finishing requirements can change tooling and process strategy. Therefore, we confirm them together before production.
For example, precision CNC machining of aluminum is common for castings, housings and brackets.
Process planning accounts for machinability, heat treatment and tolerance.
Tool life, finishing and inspection requirements are reviewed together.
Anodizing, plating, deburring and assembly are coordinated after machining.
Quality control
Inspection Requirements Defined Before Machining
Before production, we identify critical dimensions, checking methods and documentation needs. As a result, inspection supports the approved drawing rather than becoming a final sorting step. Our approach follows IATF 16949 principles where applicable.
- Drawing and DFM review before programming
- Process checks during CNC machining
- CMM and dimensional inspection for critical features
- Packing and documentation included in delivery
Buyer FAQ
Questions Before You Upload a Drawing
To begin, start with the precision CNC machining information you have. If a requirement is missing, our engineering team will clarify it during review.
What files are needed for a CNC machining quote?
For example, send STEP or IGES files with a 2D PDF, DXF or DWG when tolerances and finishes are critical. Please also include material, quantity, finishing and delivery requirements.
Can you machine castings and other supplied components?
Our precision CNC machining service can process aluminum castings and other components under one quality plan. In addition, we review fixtures, datums and stock condition before quoting.
Do you support prototypes and production volumes?
Prototype and production orders are both supported by the same process. Consequently, machine selection and workholding are planned around both the immediate order and expected volume.
What tolerances can be reviewed?
Initially, send the drawing with the critical tolerances identified. Then our team reviews the features, material, process and inspection method before confirming capability and quotation.
Can you provide finishing and inspection together?
Certainly, secondary operations and inspection remain part of the same project plan. Therefore, finishing, critical dimensions, packing and documentation can be coordinated before delivery.
