CNC Broaching is a core in-house capability at VT machining, supported by full inspection and a single engineering contact from quote to delivery.
Broaching pushes a toothed tool through or across a part to form keyways, splines and internal profiles. Because the same engineers handle quoting, programming and inspection, nothing is lost between your drawing and the finished part.

CNC Milling BuilderConfigure CNC milled metal parts: plate or block stock with milled pockets, grooves, edge steps, and surface finishing options. Every builder includes the Freeform Corner & Region Editor: cut or add material of any shape directly on the 3D model, then submit an RFQ.This tool is for visual configuration only. Final dimensions, tolerances, materials, coatings, and manufacturability will be reviewed from your drawing or specification.

FREQUENTLY ASKED QUESTIONSWhat milled features can I configure?
Edge grooves, center pockets/cavities and edge steps with adjustable width and depth on plate or block stock, plus surface treatments such as anodizing, nickel plating, powder coating and black oxide. 3-, 4- and 5-axis setups can be requested.
What tolerances and surface finish can milling hold?
Standard milled tolerances of +/- 0.05 mm, tighter on request, with surface grades from roughing (Ra 3.2) down to fine finishing (Ra 0.4). Tight-tolerance features are reviewed against your drawing.
CNC Broaching is a subtractive process in which a rotating multi-flute cutter removes material from a fixed workpiece to create flat faces, pockets, slots, bosses, holes and free-form 3D surfaces. Because the tool can approach from several directions on 3-, 4- and 5-axis machines, complex prismatic parts are produced in very few setups.
VT machining runs CNC Broaching in-house, so scheduling, quality and revisions stay under one roof. Broaching pushes a toothed tool through or across a part to form keyways, splines and internal profiles — and the parameters are set from your material and geometry, not a default recipe. Send a CAD model or a 2D print and we will confirm feasibility, tolerances and lead time before you commit.
How CNC Broaching Works at VT machining
Rotating multi-flute cutters remove material as the metal workpiece is driven through programmed tool paths on 3-, 4- or 5-axis machining centres. Climb milling, step-over and depth-of-cut are set so chip load stays in the ideal band for the alloy.
Every job begins from your CAD model or 2D drawing. Fixturing and tool paths are planned so the most critical dimensions are produced in the most rigid, repeatable setup. Critical dimensions are checked on the first part and monitored through the run.

CNC Broaching Tolerances & Surface Finish
For CNC Broaching, dimensional and positional tolerances around ±0.01 mm are routine, tightening toward ±0.005 mm on precision setups. Surface finish on machined faces typically falls in the Ra 0.4–1.6 µm range depending on tooling and pass strategy.
Final tolerances are governed by the material's behaviour, wall thickness and overall stiffness. We give honest DFM feedback if a callout would be costly or better achieved another way.

Figures are typical in-house capability. Send your drawing and we will confirm what is achievable for your specific part.
CNC Broaching by Metal — Choose Your Material
Choose a metal below for grade-level detail, achievable tolerances and typical parts in that material.
Small design adjustments often cut cost and lead time. Generous internal radii, sensible pocket depth-to-width ratios and avoiding very thin unsupported walls all reduce cost and improve accuracy in metal. If you send your model early, we will return practical DFM feedback before you commit to production.
Secondary Operations & Finishing
Most metal parts need some finishing, which we manage in-house or through vetted partners. Options include deburring and edge-breaking, heat treatment, surface grinding, polishing, and plating or anodising for corrosion resistance and appearance. Give us the finished-part requirement and we will sequence every operation correctly.
CNC Broaching Quality & Inspection
Quality is built in, not inspected on. We monitor key features during the run and confirm them at final inspection, with CMM verification available for tight tolerances. We provide the inspection and traceability records your quality system requires.

Ordering metal parts is straightforward. Provide the drawing, material, quantity and any certification needs. Our engineers reply — in English — with feasibility, pricing and a realistic lead time, usually within one business day.
Have a drawing ready? Send it with your quantity and material for a quotation, usually within one business day.
Achievable tolerances for CNC Broaching depend on the alloy, geometry and feature size. Milling holds positional and dimensional tolerances to around ±0.01 mm, tighter with precision setups. Exact figures are confirmed against your drawing callouts.
What surface finish is achievable on with CNC Broaching?
Surface finish on the part is controlled to your specification; we confirm the achievable Ra against your callout.
Does CNC Broaching require dedicated tooling?
Most CNC Broaching work uses standard cutting tools and CNC programs; dedicated fixtures are made only when geometry or volume requires them.
What is the typical lead time and minimum order for CNC Broaching?
CNC Broaching prototypes for can be produced quickly and scaled to series production. Send your drawing and quantity and we will advise lead time and any minimum order.
Can VT machining make custom parts to my drawing?
Yes. CNC Broaching is made to order from your CAD/2D drawing. Share your geometry, material grade, tolerance and quantity and we will confirm feasibility, lead time and pricing.
