Guides, DFM notes and shop-floor data for engineers and machinists. Turning, milling, sheet metal and finishing, written by people who run the machines. Send a model and we return a quote with manufacturability feedback in 12 hours.
Four things that cost time on real jobs. If any of these sound familiar, the fix is usually information, not a new machine.
You get a price and a lead time, nothing else. Then the part hits a thin wall or a deep pocket and the tool cannot reach it. Rework starts before the first chip is cut. Ask for DFM notes with every quote and you catch this in the office, not on the floor.
A chamfer is called out on the print but missing from the STEP file. The machinist programs what they see and the inspector measures what the drawing says. One revision note up front removes the argument and the second setup.
6061-T6 and 6061-O machine nothing alike. Speeds and feeds lifted from a generic chart burn tools or leave a poor finish. Check the temper and the stock form before you set the program.
Hardcoat anodizing adds thickness that shifts a tight bore. If the finish is not in the same conversation as the tolerance, the part passes inspection and still will not fit. Both belong on one sheet.
Two things decide whether a part is easy or painful: how it is designed and how the shop reads the drawing.
Most turning advice stops at surface speed. The decisions that matter come earlier: how the part will be held, where the tool enters, and which feature needs the tightest tolerance. A shaft with a 0.05 mm runout callout over 200 mm needs a different setup than the same shaft with a loose callout.
We look at three things on every turning job: the datum, the wall thickness, and the thread relief. Get those right and the rest follows.
Pocket depth, corner radius, and tool reach set the cost of a milled part more than the material does. A 6 mm deep pocket with a 3 mm corner is routine. The same pocket with a 1 mm corner needs a small tool, slow passes, and a higher risk of a broken cutter.
Where a corner radius has to be small, say so and explain why. We can usually reach it with a different strategy, but knowing that it matters changes how the job is planned.
Sheet metal follows the same logic. Bend radius, hole-to-bend distance and grain direction decide whether a bracket forms cleanly or cracks at the first bend.
Pick the route by geometry, quantity and tolerance, not by habit.
| Part feature | Best route | Watch for |
|---|---|---|
| Round, single-axis, tight OD | CNC turning | Runout over long lengths |
| Prismatic, many faces | 3-axis or 4-axis milling | Fixture count |
| Complex, one setup | 5-axis machining | Higher hourly rate |
| Thin flat panels | Sheet metal fabrication | Bend distortion |
| Organic shapes, low volume | 3D printing | Weaker in load paths |
| Thick walls, high volume | Die casting | Tooling lead time |
One shop for prototypes through production, so the process choice does not get locked in by a supplier list.
16 simultaneous 5-axis centers for parts that need multiple faces in one setup. Fewer fixtures, better position accuracy between features.
12 four-axis mills and 27 three-axis machines handle prismatic work and higher volumes without tying up the 5-axis capacity.
16 mill-turn centers and a Ø400 mm rotary table cover shaft work, bushings and parts that mix turned and milled features.
From one piece to 10,000+ part runs with no minimum order quantity. Good for fit checks before committing to tooling.
Laser cutting, forming and welding for brackets, enclosures and panels. Bends planned around grain direction.
Anodizing, plating, powder coating, blasting and laser marking. Minimum character height 1.5 mm for engraving.
| Item | Range | Notes |
|---|---|---|
| Maximum part size | 4,000 mm | Long parts on the large travel mill |
| Large travel | 4,000 × 400 × 150 mm | Rail and beam work |
| Medium travel | 750 × 1,150 × 550 mm | Most enclosure and plate jobs |
| Tolerance | ±0.005 mm | ±0.0002 in, verified by inspection |
| Finish range | Ra 0.2–3.2 μm | Depends on process and material |
| Aluminium | 6061, 7075, 2024, 6082 | Temper changes the cut |
| Stainless | 303, 304, 316L, 17-4PH | 303 machines cleanest |
| Titanium | TA2, TC4 (Ti-6Al-4V) | Slow speeds, sharp tools |
Six things we can point to, not adjectives.
Three wholly-owned plants and 150 technicians. The process knowledge comes from production runs, not from a brochure.
Held on production parts and checked with calibrated instruments, not just on a lab sample.
Quotation and free DFM analysis within 12 hours. Production can start within 24 hours of approval.
Raw material check, in-process monitoring and final inspection. Reports on request.
One prototype or a 10,000+ part run. Same process discipline either way.
ISO 9001:2015, IATF 16949:2016, ISO 13485:2016 and ISO 27001:2022.
Traceable material, tight position tolerance, no tool marks in load paths.
Repeatable parts across runs, process control that holds after the first article.
Clean finishes, small features, documented inspection at each stage.
Brackets, housings and joint parts that must line up on assembly.
STEP and STP cover most work. IGES, X_T and native SolidWorks or Fusion files are fine too.
Send 2D drawings as PDF alongside the model when tolerances and finishes matter. The model gives geometry, the drawing gives intent.
If the main form is round and concentric, turning is faster and holds diameter tolerance more easily.
Parts with off-axis holes, flats or slots usually go to a mill or a mill-turn center. A part that is mostly round with a few milled features is often cheapest on a mill-turn machine.
It depends on depth. A shallow pocket can take a 0.5 mm corner. A 20 mm deep pocket with a 0.5 mm corner needs a long, thin tool and will be slow.
If the small radius is functional, say so and we will plan for it. If it is cosmetic, a larger radius usually cuts cost.
Yes. Hardcoat adds roughly 25 to 50 μm per surface, which is 0.05 to 0.1 mm on a diameter.
For a press fit or a tight bore, mask the feature or adjust the pre-plate size. Put the finish callout on the drawing so it is planned in, not discovered later.
Down to about 0.8 mm on aluminium with the right support and light passes. Below that, success depends on part geometry.
Thin floors and long unsupported walls are the hard cases. If the wall is critical, we may suggest a temporary support rib or a change in how the part is held.
We quote ±0.005 mm as the standard precision limit. Anything tighter needs a review before we commit.
Sometimes the answer is a different process, such as grinding after machining, or a change in datum so the critical feature is cut in the same setup as its reference.
One part. There is no minimum order quantity, and prototypes go through the same inspection as production runs.
For a single piece, expect to pay for setup time. That cost does not change whether the run is one part or one hundred.
