Cutting and processing

We cut glass on a CNC machine and prepare blanks for the next route: edge work, holes, bending, or lamination. Standard cutting thicknesses are 2–8 mm; under 2 mm (down to 0.55 mm) and above 8 mm are handled as special projects. Maximum cutting format is 2000 × 1500 mm, with straight and shaped cuts at ±1 mm accuracy. Edge processing and drilling run on a manual machine or a 5-axis CNC with milling — within the same thickness and size limits.

Cutting and initial glass processing

Octoglass cuts and initially processes flat glass on our own site. Nesting runs on a computerized CNC machine: the program sets the outline, and the operator does not intervene in the cut itself — that reduces part-to-part scatter and keeps the result predictable for downstream stages.

The standard working thickness range is 2–8 mm. If you need to cut under 2 mm (down to 0.55 mm) or above 8 mm, we treat the job as a special project: we assess fit, route, and risk before launch, not after a failed first attempt.

Maximum cutting format is 2000 × 1500 mm. Within that envelope we cover compact technical parts and larger blanks for automotive or special glazing — provided thickness and geometry are agreed up front.

Straight and shaped cuts are available. Straight outlines suit rectangular and simple polygonal parts; shaped cuts fit when a curved or complex edge is needed already at nesting, not as a later “by-eye” fix.

Cutting accuracy is ±1 mm. That is a fixed production corridor given roller-cut physics and head positioning: it is enough for most blanks, and critical fits should be drawn with allowance for this tolerance.

Cutting is not “just split the sheet” — it is the first step of a process chain. After nesting, the edge keeps break marks and stress zones; without follow-on edge work the blank handles transport and later stages worse. That is why the “cut → edge/holes” route is often planned together.

We work from customer drawings and digital models: DXF/DWG are preferred, though a PDF or sketch can support a first assessment. The earlier outline, thickness, and next stage are locked, the shorter the path from the first sheet to stable lot repeat.

For B2B and OEM work, cutting works as a standalone service or as a stage in the full Octoglass loop — handing off to faceting, bending, or lamination on the same site. On the site we publish confirmed format, thicknesses, and accuracy; specific tolerances and timing are agreed per order.

Edge processing and hole drilling

After cutting, Octoglass processes edges — grinding or polishing — and drills holes. This is a separate stage tightly linked to nesting: it removes sharp break marks, lowers the risk of spontaneous breakage in transit, and prepares the blank for bending, lamination, or assembly.

Two routes are available. The manual machine is used where nothing else can close the job: a non-standard fit, limited edge access, or geometry better finished by hand under operator control.

The second route is a 5-axis CNC machine. On it we grind and polish edges, drill holes, and mill when needed. CNC fits when series repeatability and accurate hole-to-outline registration to an agreed program matter.

Milling on the 5-axis machine widens machining geometry: not only round holes, but more complex pockets and contours when the drawing calls for them and the material supports a stable cycle.

Thickness and format limits match cutting: standard 2–8 mm, format up to 2000 × 1500 mm; under 2 mm (down to 0.55 mm) and above 8 mm are special projects. That makes it easier to join nesting and finishing in one brief without hidden size surprises.

Grinding covers baseline edge prep; polishing is for a smoother, visually and tactilely cleaner edge for visible zones or the next process step. We lock the mode at assessment: “polish everywhere” without a reason only lengthens the cycle.

Hole drilling is planned with the edge work: diameters, edge offsets, and operation order affect blank strength. If holes are critical for fasteners or sensors, send a drawing with tolerances up front rather than clarifying after the first lot.

A outline, thickness, hole list, and a note on manual versus CNC and grinding versus polishing are enough to start assessment. Exact pricing and timing follow once inputs are agreed; related stages such as faceting, bending, and lamination can sit in the same enquiry.

FAQ

Which drawing formats do you accept?
DXF/DWG are preferred. You can also send a PDF drawing or sketch in any graphic format for preliminary evaluation - digital geometry is usually needed for production.
What information do you need to assess a cutting request?
Briefly describe the task and share available inputs. The exact list depends on the project.
Is it possible to provide, for example, a 3D model or a point cloud for cutting?
It is possible, but additional processing of non-standard data and converting them into drawings will require the inclusion of additional services in the order.
What type of glass cutting do you use?
We use roller cutting with diamond or carbide rollers, in some cases, crystal cutting can be used. The cutting tool makes a "scratch" on the glass, which then breaks the glass.
What glass sizes and thicknesses can you cut?
Maximum format is 2000×1500 mm. Standard thicknesses are 2–8 mm. Under 2 mm (down to 0.55 mm) and above 8 mm are special projects. Straight and shaped cuts are available.
How do you process edges and drill holes?
Two routes: a manual machine where nothing else works; or a 5-axis CNC for grinding/polishing, drilling, and milling. Thickness and format limits match cutting.
How precise is the cutting?
Cutting runs on a computerized CNC machine. Cutting accuracy is ±1 mm.
Can you remove the energy-efficient coating around the glass perimeter?
Yes, that is possible.
Can I order cutting only, without further processing?
Yes. Cutting can be a separate service or the first stage of a complete route at the Octoglass site. However, we warn you that glass without edge treatment (grinding or polishing) contains stress zones after breaking along the cutting line and may spontaneously collapse, for example, during transportation. Additionally, it should be borne in mind that in the process of breaking glass along the cutting line, cracks and small chips may remain on the glass, which it is also desirable to remove by processing the edge.
But what if the glass is broken when cutting the raw materials?
In the case of working with toll-free raw materials, the possible level of glass impact is agreed upon with the client in advance, which depends on the complexity of the cut and the supplied raw materials. In the case of exceeding the declared fight, the service provider compensates for the fight in the amount of no more than proportional to the cost of the cutting service.
I assumed that so many products would be cut out of my sheet of glass, but it turned out to be less. Why?
When cutting several products from a single sheet of glass, they are arranged in an optimized manner using the glass cutting machine software. Not all geometries, especially those with curved shapes, can be placed on a sheet of glass in such a way that no glass clippings remain.
Is it possible to pick up the glass clippings?
Rectangular pieces of glass can be picked up along with the rest of the order. In this case, it is necessary to indicate this fact in advance when placing an order. Glass scrap, including trimmings that do not preserve or retain their squareness when breaking glass during cutting, are disposed of and are not subject to delivery to the customer. Glass offcuts must be disposed of in accordance with the law — they must not be thrown away as household waste.
Is glass washing possible after cutting?
Glass washing is possible only after full processing of all edges and holes, because unprocessed edges damage the washing rollers.
