Jewelry Laser Cutting Machine for Name Necklaces, Tags and Letter Pieces

A 300 × 340 × 320 mm bench machine at 30 kg, air cooled, with no chiller to plumb in. Cutting and marking share one 70 × 70 mm field, and the welding source sits in the same cabinet.

Pieces a Jewelry Laser Cutting Machine Cuts

Five kinds of piece have been through this machine and can be shown cut. They are one job seen five ways, which is why one machine covers them.

Pending photo · script

Name necklaces

An outline with no straight line in it. Letters join along the baseline, stroke width shifts along its own length, and the hanging points go where the name balances rather than where the drawing ends.

Pending photo · tag edge

Tags and pendant blanks

A simple perimeter judged entirely on its edge, plus one decision that cannot be undone later: where the hole sits. A tag is mostly edge.

Pending photo · initials

Letter pieces

Single characters cut as initials, monograms and charm sets, usually a run of the same character offered in a set of sizes.

Pending photo · emblem

Small metal graphics

Logos, symbols, hearts, pet silhouettes and club emblems. The artwork arrives as somebody else’s file and has to be made cuttable before it is anything else.

Pending photo · outline

Sheet outlines

The shapes you cannot buy: a blank in your own proportion, a bar in your own length, a plate shaped to sit against a piece you already made.

Every one of them is thin sheet, cut to an outline, then marked, drilled or welded before it is a finished piece.

Working envelope

The 70 × 70 mm Nesting Field

70 × 70mm · shared by cutting and marking

Seventy millimetres square is a nesting area for this class of piece, not a ceiling. The practical question on the bench is how the blank gets laid out, not whether the piece fits.

Time and attention in a cutting job go into the set-up, not the cut.

One clamp-up

The blank goes into the fixture once. Everything laid out inside the field is cut from that one position: a row of initials, a name plus the spare letters you know will be asked for, a tag and the emblem that goes on its back.

Changing blanks is handling. Changing set-up is a job.

Same field, same origin

The MOPA source marks in this same 70 × 70 mm field, at 0.01 mm accuracy, at the same working height, referenced to the same origin.

A piece cut in that field is already in position to be marked in it, so a serial number goes on the back of a tag without the piece being lifted and re-aligned on another bed.

The planning unit

One blank, one clamp, one field, as many pieces as the layout holds. That is the smallest unit of planning on this bench.

Standard kit for cutting work

Flat Sheet on a Jewelry Laser Cutting Machine

The cutting fixture is the standard kit for cutting work on an M3. It is listed as an accessory, and for marking work it genuinely is one — but nobody cuts sheet on this machine without it.

What it does is hold the blank flat and hold it down, across the whole area being cut, for the whole duration of the cut.

Sheet arrives with a memory of the coil it came off and is rarely dead flat out of the packet. A blank high in the middle by a fraction is cut at one setting on the edges and another in the centre: through in some places, holding on in others, discovered when the piece will not come out.

HELD DOWN ACROSS THE CUT AREA Pending photo · blank clamped flat Pending photo · extraction at the bed

Red light, before anything fires

  • Margin on every side, with the whole layout inside the sheet.
  • No stroke running over a scratch, a plating defect or a rolled edge.
  • The hanging hole where the piece will balance on the chain.
  • On a second run, the new layout clear of holes cut in the previous one.

Fume extraction is the other half of the standard kit. Cutting removes metal, and what is removed has to go somewhere other than back onto the blank, onto the lens and into the room you work in.

The failure point

The Moment of Break-Through

A cutting job does not fail at the start. It fails in the moment the outline finally goes through, and that is what separates cutting from marking on the same machine.

Up to that moment the blank is one piece of metal and the fixture is holding all of it. The instant the outline closes, the piece inside it is attached to nothing.

Marking never has this moment. The piece it works on is the piece it started with, still in one piece at the end. Cutting ends by producing a loose object, and every decision before that point is about what happens when it becomes one.

Failure one

Drop

The piece settles a fraction and the last of the cut lands on the piece rather than on the line. What turns up afterwards is a mark across an edge that was already finished.

Failure two

Lift

The edge nearest the last cut rises and the pass finishes across the face instead of along the outline. On a plated blank that mark goes straight through the plating.

Failure three

Shift

The piece moves a fraction and the outline closes in the wrong place. On script lettering that is the difference between a joined name and a handful of loose letters.

Sequence and holding

INTERIOR OPENING FIRST PERIMETER LAST HOLDING TAB WHERE NEEDED BROKEN AND DRESSED BY HAND Pending photo · tab dressed
01Interior openings first
The waste inside a letter, the counter of an a, an o or an e, comes out while the piece around it is still part of the blank and still clamped. Cut the perimeter first and the same waste has to be taken out of something already loose.
02Perimeter last
The outline that frees the piece is the last thing cut, so nothing is loose while there is still cutting to do.
03Holding tab where a shape needs one
A small tab left in the outline, broken and dressed by hand afterwards. That is a decision made in the artwork, not a setting on the machine.

The fixture keeps the blank down through all of it, so the only thing that changes at break-through is that the piece is free — not that the piece has moved.

This is the part of cutting that is learned rather than specified, and it decides whether a cursive name comes off the bed in one piece.

Off the bed

Release, Waste, Skeleton and Edge

When the cut is done the blank comes out of the fixture as a set of parts, and there is an order to taking it apart.

01

Interior waste first

The small islands from inside letters, and from any enclosed shape in a logo, come off the bed before anything else.

They are the pieces most likely to be lost.
02

Pieces lifted, not pushed

Each piece is lifted clear of the skeleton rather than pressed out of it.

Pushing a thin piece against the blank it came out of is how a fine stroke bends.
03

Skeleton kept until checked

On a run of initials the skeleton stays on the bench until every piece has been looked at.

It is the record of where each piece came from.
04

Tabs broken and dressed

Tabs come off next and are dressed back to the outline, positioned where the next operation covers them: under the jump ring, behind the bail, on the edge a setting hides.

Tab position is chosen in the artwork.
05

Edge read under the microscope

Through evenly all the way round, fine strokes holding their width, and how much the finishing step will have to take off.

That reading is fed back into the settings for the next blank.

The edge is what the customer sees on a name necklace. Reading it at the same bench, before the piece goes anywhere, is why the first piece of a new job is cut, looked at, and then cut again.

Files that cut

Cuttable Artwork: Strokes, Islands, Hanging Hole

Most cutting problems are artwork problems, visible in the file long before they are visible in metal. A cut outline is a physical object, which imposes conditions a printed version never had to meet.

TOUCHINGJOINED

Connected strokes

In a script name the letters must actually join along the baseline. Two shapes that touch at a single point on screen become two separate pieces of metal.

MANY ISLANDSONE ISLAND

Islands that drop out

Every enclosed area is an island that falls out of the blank and has to be planned for. Fine on the counter of an o; a different job when a logo has forty of them.

HAIRLINEREAL WIDTH

Stroke width in metal

Hairlines drawn to be printed have to be given real width. A stroke below what the metal can hold does not survive polishing.

ON THE EDGEMARGIN LEFT

The hanging hole

Placed where the piece hangs the way it is meant to, sized for the jump ring going through it, far enough from the edge that the metal between hole and outline is not the weakest thing about the piece.

Open paths, duplicated outlines and text never converted to curves get resolved before they become cut instructions. A photograph of a signature is a conversation to have before the sheet is in the fixture.

First physical piece

First-Piece Proofing on Your Own Bench

Custom work is not sold from a drawing. It is sold from a piece somebody has held, and the first physical piece is where a custom order is actually decided.

FILECUTRELEASEHOLD ITCHANGERE-CUTSIGN OFFONE STORED RECORD

Five things nobody sees on a screen

  • The strokes are too fine for the metal.
  • The name wants to be shorter to sit right on the chain.
  • The hole is in the wrong place and the piece tips forward when it hangs.
  • The edge finish wants to be softer in the hand.
  • The initial should have been in the other case.

Those changes go into the file, and a second piece is cut from the same blank stock at the same set-up.

A proofing round that runs through a subcontractor is measured in shipping, which is why so much custom work gets sold from renderings and then argued about after delivery. A proofing round on your own bench is measured in the time it takes to re-cut one blank.

Signed-off record

Repeat Orders From a Signed-Off Record

The first piece of a design is the expensive one. Everything after it should cost almost nothing to set up, and whether it does is decided by what was kept.

01

Cut file

With its layout inside the field, not the outline on its own.
02

Corrected artwork

As it was fixed to be cuttable, not as it arrived.
03

04

Settings

05

Tab positions

And which operation covers each one.
06

Reference piece

The signed-off piece itself, to hold against the tenth.

The tenth piece is the first piece.

Called back together, the six make it so. Called back partially, they do not: a file without the fixture position means finding it again, and a file without the reference piece means nobody can tell whether the tenth is right.

Pending photo · settings Pending photo · reference

That is what turns one-off custom work into stock you can sell twice. A letter set cut once is a set you can offer in a range of sizes forever, and the emblem made cuttable for a club is the emblem you cut again for their next order.

It also changes who can run the work: a signed-off record is a job somebody else in the shop can run from the screen, against a reference piece they hold up to what came off the bed.

Where the list ends

That is the list because that is what has been through the machine. A short list that is true beats a long one that is a guess, and anything outside it gets answered with a piece rather than a claim.

Two numbers deliberately not published

Sheet thickness range
Not published
Cutting speeds
Not published

On this class of work a single number would mislead. The answer depends on the metal you use, on how your sheet was rolled and annealed, on how fine the finest stroke in your artwork is, and on which configuration the machine is built in.

A figure that is true for a plain tag in one metal is not true for a script name in another, and quoting the flattering one is how equipment gets sold and then disappoints.

So the answer given instead is a physical one: send the artwork and a piece of the sheet you actually work in. If your piece needs a different configuration, you hear that before you buy rather than after.

What to send

Cutting Sample Checklist: Artwork, Metal, Holes

The more of this that comes with the piece, the closer the sample is to the job you actually run.

  1. Artwork
    The artworkPLT, DXF, AI, CDR, DWG, or a PNG, JPG or TIF if that is all that exists. Say whether it was prepared for cutting or came straight from a customer.
  2. Metal
    The metalA piece of the sheet you buy, not a similar one, and what it is. Sheet from different sources in the same nominal metal does not always behave the same.
  3. Size
    The finished sizeThe size at which the piece sits right, when that differs from the size the file was drawn at.
  4. Holes
    The holesWhere they go, how many, and what jump ring or bail goes through them. Say if the piece will be welded on rather than jump-ringed, because that changes where metal needs to be left.
  5. After
    What happens afterMarked on the back, polished, plated or tumbled, and what the finished edge is supposed to look like in the hand.

What comes back

  • The cut piece, marked on the back if you asked for that.
  • The settings that produced it, written down beside it.
  • A note on anything in the artwork that had to change to make it cuttable.

Who cuts on it

Benches That Cut Their Own Blanks

  • Name necklace and nameplate sellersOn Etsy, Shopify and their own storefronts. Bringing the cut in-house turns a rush order into a yes and a proof into something the customer holds.
  • Custom studios and independent designersAlready making to order. The cutting side is the front of a process they own the back of, and a design goes from file to a piece they can photograph in the same working day.
  • Permanent jewelry businessesWelding a chain on the wrist and selling a charm with it. Cutting their own charms, tags and initials makes the charm range theirs rather than a wholesale catalogue everybody at the same event is also selling.
  • Repair counters with a bench in the backBought for repair welding, and the sheet work turns out to fill the hours between repairs, on stock they cut themselves.
  • Small brands and sample roomsNeeding blanks, findings and plate shapes no supplier stocks in the proportion they want, and who would rather cut fifty of their own than order a thousand of somebody else’s.
