Waterjet Cutting Services: Canadian Buyers’ Supplier Comparison

Shortlist uMake for advertised Canada-wide ordering and delivery, or Antech for its Toronto/GTA waterjet offering; choose on confirmed stock acceptance, cutting requirements and delivered-part scope. [2][5]

Compare the same three requirements

uMake

• Stock and capacity: uMake accepts customer-owned material if it is flat, clean and suitable for water exposure and abrasive cutting. Advertised part capacities are 144 × 72 in for its dynamic-head system and 120 × 60 in for 5-axis work. Its page gives conflicting thickness limits: the opening description says up to 6 in, while the capabilities section lists 12 in (300 mm) and focuses precision work on material under 4 in. Neither headline establishes the capacity for your order. Obtain written confirmation of the applicable limit, material, process and tolerance before quoting or shipping stock. [2]
• Drawing inputs: For 2D work, uMake requests clean, 1:1 DXF/vector geometry with closed paths, correct units and no duplicate or overlapping lines. For 5-axis work, it prefers STEP/STP finished-part geometry plus a dimensioned PDF showing bevels, edge directions and tolerances. [2]
• Cutting quality: Quotes default to Q3 edge quality, with automatic kerf offset and a 5-axis taper-compensation option. Obtain confirmation of dimensional tolerances for your material and critical features. [2]

Antech

• Stock and capacity: Ask Antech to confirm whether it accepts customer-supplied stock. It advertises abrasive cutting up to 6.5 in thick, a maximum sheet size of 60 × 120 in and a 78 × 120 in working area. [5]
• Drawing inputs: Antech accepts DXF, DWG, PDF, CDR and EPS vector files and says it cuts directly from the submitted vector file. [5]
• Cutting quality: Antech lists typical tolerances of ±0.010 in and describes abrasive cuts as burr-free. Its separate tighter-accuracy claims require clarification before specifying them for a waterjet order. [5]

Confirm material and stock handling before dispatch

uMake says specialty stock can go to its Montréal facility, but stone slabs, large composite panels and delicate finished surfaces require advance confirmation of handling and fixturing with [email protected]. [2] Its material thickness table gives maximum thicknesses without units and lists glass’s maximum quality thickness as 1/5″; confirm both before relying on those entries for a job. [2]

For either supplier, request written agreement on material grade, thickness, sheet dimensions, surface protection, receiving-condition checks and responsibility for damage. Obtain stock approval before shipping, particularly where acceptance remains unresolved.

These are proposed purchasing terms, not additional commitments established by the suppliers’ cited pages. [2][5]

Specify edge quality and dimensional accuracy separately

uMake’s Q1–Q5 grades describe edge quality; separately, its FAQ gives typical tolerances of ±0.1–0.25 mm (about ±0.004–0.010 in), depending on material thickness, geometry and cutting speed. Antech lists a typical ±0.010 in. Do not treat an edge-quality grade as a dimensional tolerance. [2][5]

uMake reports typical abrasive kerf of 0.02–0.05 in (0.5–1.3 mm) and automatic CAM toolpath offsets. It asks buyers to flag critical-fit tolerances for confirmation against the material and process. [2] Specify those tolerances rather than using kerf width as an acceptable dimensional error.

uMake also warns thick-material 2D cuts can taper inward at the bottom edge, while its 5-axis head offers dynamic taper compensation. [2]

Antech’s setup tables give its typical tolerance as ±0.010 in, but its benefits text claims tolerances as tight as ±0.005 in. Material-specific tighter entries are labelled “Laser cut”, so do not treat them as verified waterjet specifications. [5]

Request separate written acceptance criteria for critical dimensions, edge finish, allowable taper and secondary finishing. Ask the supplier to confirm each against the specified material, thickness and features—not merely its general capabilities.

Agree nesting, stock risk and remnant ownership

Ask uMake and Antech to confirm nesting methods and efficiency, customer-stock title and risk, remnant ownership, offcut return and scrap-disposal arrangements. [2][5]

Agree these responsibilities before authorising cutting:

• Nest control: Identify who prepares and approves the layout, including orientation and protected-surface constraints.
• Stock allowance: State the sheet quantity the price assumes and who approves extra sheets or changed layouts. If material recovery matters, request a documented nest or agreed stock-use basis.
• Ownership and risk: Allocate ownership of supplied sheets, usable remnants and scrap, plus responsibility for damaged material. Specify what gets returned or disposed of, by whom and at whose cost.

Define complete labelled kits

Antech describes its abrasive cuts as clean and burr-free. [5] Treat this as an edge claim, not acceptance of a deburring operation or complete-kit specification. Ask uMake and Antech to agree full kit-acceptance requirements in writing. [2][5]

Proposed purchase requirements—not documented supplier commitments:

• Edges: Agree which edges require deburring, the operation’s scope and the acceptable finished condition.
• Identification and packaging: Require a manifest linking each part number and drawing revision to its quantity per kit. Agree labels or markings, kit grouping and protective packaging, including marking restrictions for delicate surfaces.
• Completeness: Require reconciliation of each kit’s contents against the manifest, separately from dimensional inspection.
• Inspection and remedies: Specify dimensions to check, tolerances, sampling and delivery records. Confirm any certificates, material traceability or inspection reports. Agree how missing or nonconforming pieces will be identified and resolved.

Model clause for supplier agreement:

Acceptance requires quantities and identification matching [approved kit manifest], parts conforming to [drawing numbers/revisions], edge condition meeting [deburring/finish specification], and inspection evidence meeting [dimensions, tolerances, sampling and records]. Packaging and marking shall follow [requirements]. Missing or nonconforming items shall be handled under [agreed remedy and timing].

Send one controlled RFQ package

Send both suppliers the same revision-controlled request for quotation: material grade, thickness, sheet dimensions, quantities, cut list, drawings, critical dimensions, delivery destination and parts-or-kits specification.

Alongside its file-cleanliness requirements, uMake advises avoiding features smaller than material thickness. [2] Antech says it cuts directly from submitted vector files; ask it to confirm the geometry agrees with the dimensioned requirements. [5]

Request explicit inclusions, exclusions and deviations against the package revision. Do not treat an attached specification as accepted until the quote confirms it.

Compare total scope and delivery

Ask each supplier to mark material, cutting, secondary finishing, identification, inspection, packaging, shipping and remnant handling as included, excluded or separately priced.

uMake offers instant online quoting with no minimum quantity; Antech offers same-day quoting. [2][5] Compare the resulting quotes, not their response promises.

uMake advertises free Canadian shipping above $250, excluding oversize parcels. It advertises delivery in 3–7 business days, while its FAQ says most projects ship in 1–3 business days depending on material availability and complexity. [2] Request separate job-specific dispatch and arrival commitments.

What to confirm with each provider

Antech’s cited page does not state a dollar rate or minimum-order charge, and neither supplier’s cited page states cancellation, change-order, payment, refund or warranty terms. [2][5]

• uMake advertises no minimums; confirm the total price against the agreed scope [2].
• Obtain dispatch and arrival commitments for the delivery destination.
• Agree cancellation, drawing-change, payment, refund and warranty terms before releasing stock or approving production.

Make the award conditional on written stock approval, drawing revision, achievable quality, nesting responsibilities and a delivered-parts or kit definition. If critical tolerances or kit completeness remain unresolved, seek clarification rather than assuming the lower quote includes them.
