TENGHUI provides custom fiber laser cutting services for precision sheet metal parts, from one-off rapid prototypes to volume production runs. Our CNC-controlled fiber laser systems deliver accurate dimensions, intricate geometries, and clean, burr-free cut edges with lead times as fast as 3 business days.
* Our laser cutting service is dedicated exclusively to certified metal sheet materials.
Our fiber laser cutting systems combine cutting speed, dimensional accuracy, and production flexibility. Parts are cut directly from CAD data without dedicated cutting dies, making the process suitable for prototypes, design revisions, and repeatable production orders.
Produce accurate external profiles, holes, slots, cutouts, and intricate 2D geometric features with high repeatability and clean edge quality.
Fiber laser technology efficiently cuts reflective materials like aluminum, copper, and brass, as well as stainless steel, carbon steel, galvanized sheet, and titanium.
Direct-from-CAD digital CNC programming makes it seamless to cut one-off prototypes, rapidly iterate design revisions, and scale to repeat batch production.
Maximum cutting thickness depends on the material grade, part geometry, feature size, overall dimensions, and required edge quality.

Advanced CNC laser cutting technology providing narrow kerfs, minimal thermal distortion, and rapid turnaround for custom sheet metal parts.
CNC-controlled laser cutting produces accurate profiles and precise feature locations for standard-sized precision sheet metal components.
Parts are cut directly from digital 3D/2D CAD data, completely eliminating hard tooling costs and making engineering design revisions faster and more economical.
Laser cutting easily produces intricate outlines, small holes, slots, ventilation cutouts, and tight internal radii that are difficult to stamp or mill conventionally.
A concentrated, high-density fiber laser beam and optimized cutting speeds strictly limit thermal input, effectively reducing edge warping in thin metal sheets.
Intelligent CAM nesting software tightly nests multiple parts across raw metal sheets, dramatically lowering scrap rates and saving raw stock costs.
Validated CNC cutting programs and monitored laser beam focal parameters ensure identical dimensional consistency from prototypes to repeat volume runs.
For standard-sized metal parts with conventional material thicknesses, TENGHUI can typically maintain a laser-cutting dimensional tolerance of ±0.1 mm.
Long cutting lengths, large overall dimensions, thick plates, and very small features may require wider tolerances. Material flatness, heat accumulation, cutting kerf, and part geometry can all affect final dimensional accuracy. Achievable tolerances are confirmed after reviewing the material specification and technical drawings.
| Laser-Cut Feature | Typical Capability | Important Considerations |
|---|---|---|
| General Cut Dimensions | ±0.1 mm | Standard-sized parts with conventional material thicknesses. |
| Hole Diameter & Position | ±0.1 mm | Applies when the hole meets recommended minimum size rules. |
| Long or Large Parts | Review Required | Overall dimensions and stock sheet flatness may affect accuracy. |
| Thick Metal Plates | Review Required | Material thickness and heat input influence dimensions and edge taper. |
| Small / Closely Spaced Features | Review Required | Heat accumulation and cutting kerf width may limit achievable limits. |
| Design Feature | Recommended Minimum | Important Considerations |
|---|---|---|
| Hole Diameter | ≈ 1× Thickness | Smaller holes may experience edge taper, distortion, or dross buildup. |
| Slot Width | ≈ 1–1.5× Thickness | Capability depends on specific alloy grade, thickness, and required edge finish. |
| Internal Corner Radius | ≥ Laser Kerf Radius | Perfectly square internal 90° corners cannot be cut directly by laser beams. |
From initial CAD data validation to dynamic nesting, multi-gas beam calibration, and final dimensional inspection.
We review the material grade, sheet thickness, overall dimensions, tolerances, order quantities, and critical edge features specified in your CAD models and 2D engineering drawings.
Part outlines are translated into optimized laser cutting toolpaths. Intelligent CAM nesting arranges multiple components across standard metal sheets to maximize material utilization and speed.
Fiber laser power, focal beam position, feed rate, and assist gases (Oxygen, Nitrogen, or compressed dry air) are fine-tuned precisely according to metal alloy type, plate thickness, and edge finish.
Components are laser cut under continuous process monitoring. Slag removal, key dimensional checks, hole positions, deburring, and lot counts are strictly verified before packaging and shipment.
Essential design parameters and geometric limits to ensure clean piercing, narrow kerfs, structural flatness, and prevent thermal distortion.
The minimum laser-pierced hole diameter should ideally be equal to or greater than the sheet thickness (D ≥ T). Smaller holes can cause piercing blowouts, taper errors, or slag accumulation.
Slot and cutout widths should generally measure at least 1.0 to 1.5 times the material thickness. Narrower slots require engineering review based on the specific metal alloy and laser assist gas.
Internal corners naturally retain a slight radius formed by the laser beam kerf diameter. When mating components require perfectly sharp inside corners, add corner relief notches or dog-bone undercuts.
Long, thin tabs and narrow strips are susceptible to thermal warpage and loss of plate flatness during cutting. To maintain structural integrity, design wider webs or allocate looser dimensional tolerances.
Placing cutouts too close together leads to localized heat accumulation, causing burn-through or deformed edges. Adequate spacing between adjacent holes preserves strict dimensional accuracy.
Please provide 3D STEP/STP models alongside dimensioned 2D PDF, DWG, or DXF drawings (1:1 scale). Explicitly define material grade, nominal thickness, total quantity, and critical tolerance bands.
For standard-sized metal parts with conventional material thicknesses, our typical laser-cutting tolerance is ±0.1 mm. Long parts, large dimensions, thick plates, and very small features may require wider tolerances. Final tolerances are confirmed after reviewing the drawings and material requirements.
Our in-house fiber laser cutting service is dedicated exclusively to metal sheet materials. For non-metal materials such as acrylic, wood, and certain plastics or rubber materials, we can arrange laser cutting through qualified manufacturing partners. Material compatibility, tolerances, lead time, and pricing are confirmed after project review.
As a general engineering guideline, the minimum hole diameter should be approximately equal to or greater than the material thickness ($D \ge T$). The recommended minimum slot width is approximately 1.0–1.5 times the material thickness. Smaller features require engineering review.
No. Laser-cut internal corners naturally retain a small radius determined by the laser beam diameter and cutting kerf width. When mating parts require sharp square corners, suitable corner reliefs (such as dog-bone undercuts) or additional assembly clearance should be included in the design.
We control thermal input through optimized laser power parameters, adaptive cutting sequences, adequate feature spacing, programmed lead-in positions, and heat-dissipating nesting layouts. Thin sheets, closely spaced cutouts, and long narrow geometries are monitored closely to prevent thermal distortion.
Nitrogen assist gas is commonly used for stainless steel, aluminum, copper, and brass to prevent edge oxidation and deliver a clean, shiny, weld-ready cut edge. Oxygen assist gas is used for thicker carbon steel to improve piercing and cutting speed, though it naturally leaves a thin oxide layer on the cut edge.
We laser cut carbon steel, galvanized steel, stainless steel, aluminum, copper, and brass. Available cutting thicknesses and achievable edge finishes depend on the material grade, part geometry, and drawing specifications.
It depends on the material type, sheet thickness, assist gas selected, and functional application. Thin sheets typically exhibit smooth, burr-free edges, while thicker plates may develop slight dross or piercing burrs. Specific cosmetic or mechanical edge deburring requirements should be indicated on your 2D drawing.
No. Laser cutting is strictly a 2D through-cutting process. Functional threads, precision countersinks, counterbores, and blind holes require secondary CNC machining or tapping/drilling operations, and should be clearly called out on your 2D engineering drawings.
