Capabilities

What the shop can hold, in what material, at what size. If your part sits outside these numbers, say so in the RFQ — we will tell you straight whether it is ours to make.

Achievable tolerances

Standard versus tight.

Standard is what we hold without special fixturing or extra inspection, at standard price. Tight is achievable and quoted with the additional setup and measurement it requires.

Feature	Standard	Tight (quoted)
Linear dimension, milled	± 0.05 mm	± 0.010 mm
Hole diameter, reamed	± 0.02 mm	± 0.005 mm
Turned diameter	± 0.03 mm	± 0.008 mm
Flatness, ground face	0.02 mm	0.003 mm
Surface finish, milled	Ra 1.6 µm	Ra 0.4 µm
Wire EDM corner radius	0.25 mm	0.10 mm

Drawings dimensioned to ISO 2768-mK unless a tighter class is specified. GD&T to ASME Y14.5 is read and honoured.

Materials

What we cut, and what we can finish it with.

Material	Grades in stock or sourced	Finishing notes
Aluminium	6061-T6, 7075-T6, 5083, ADC12	Anodise types II & III available
Stainless steel	303, 304, 316L, 17-4 PH	Passivation to ASTM A967
Tool steel	D2, H13, S7, SKD11	Hardened to 62 HRC, then ground
Carbon & alloy steel	1045, 4140, 4340	Black oxide or zinc plating
Titanium	Grade 2, Grade 5 (Ti-6Al-4V)	Medical-device work, traceable
Copper & brass	C101, C110, C360	Electrode and busbar work
Engineering plastics	PEEK, PTFE, Delrin, UHMW-PE	Dedicated tooling, no metal cross-contamination

Material certificates (EN 10204 3.1) are supplied with every batch on request, and are standard on medical-device and oil-and-gas jobs.

Volumes & lead times

Prototype to production, same shop.

Volume 01

Prototype · 1–10 pieces

For design verification, where the drawing may still change. Programmed and run on the 5-axis machines to avoid multi-setup errors.

Lead time 5 working days
Dimensional report included
Rush 48 h available

Volume 02

Bridge · 10–500 pieces

Soft-jaw fixturing and a proven program, before committing to hard tooling. Where most of our customers live.

Lead time 10–15 days
First article approval
Price break at 50 & 200

Volume 03

Production · 500+ / year

Dedicated fixtures, unattended overnight running and a blanket order with scheduled monthly releases.

Kanban or scheduled release
SPC on nominated features
Consignment stock possible

Engineering support

We read the drawing before we price it.

Every RFQ gets a manufacturability review from a programmer, not a sales desk. Typical notes we send back:

A ±0.01 mm callout on a clearance hole that only needs ±0.1 mm
An internal corner radius smaller than any cutter — EDM or relief needed
A pocket depth-to-width ratio that will chatter and cost you finish
Two datums that cannot both be held in one setup
A material grade with a 6-week lead time when an equivalent is on the shelf

File formats

What to send.

3D model	STEP, IGES, Parasolid, SLDPRT
Drawing	PDF or DWG with GD&T
Sheet metal	DXF flat pattern + 3D
Inspection	Ballooned drawing, if you have one
Max upload	80 MB per RFQ
