Our CNC Machining Capabilities
At HLH, we have over 50 high precision CNC mills, lathes, and pride ourselves on being able to machine whatever you need, from simple, 'as-machined' workholdings to complex, organic geometries with tight tolerances. On request, we can also produce parts with EDM and grinders. Build envelopes, minimum feature sizes and design guidelines vary for milling and turning.
CNC Machining Tolerances
Maximum Part Size
3500*2700*1200mm for metal parts
3500*1200*850mm for plastic parts
Standard Lead Time
Tolerances are controlled to DIN-2678-1 Fine for metals and Medium for plastics as standard
Threads and Tapped Holes
HLH can accommodate any standard thread size.
HLH can manufacture and inspect to tight tolerances per your drawing specifications including GD&T callouts.
Sharp edges are broken and deburred by default
The standard finish is as-machined: 125 Ra or better. Additional finishing options can be specified when getting a quote.
Advantages of CNC Machining
CNC Machining Materials
CNC Machining Applications
The speed and versatility of CNC Machining lets product developers create physical snapshots of their designs through the iterative process.
The range of materials available, low cost per unit, and speed of production makes CNC a great option for prototyping.
High-quality finish, vast material options and precise tolerances have made CNC a favorable technology for end-use parts.
