Research Labs & Scientific Parts Machining

Wikipedia defines a scientific instrument as “a device or tool used for scientific purposes, including the study of both natural phenomena and theoretical research” (source 1). Scientific parts machining is the parts side of that: housings, mounts, stages, sample holders and rig hardware for instruments and experiments, quoted from your print like any other part.

One-off and low-volume work is the core of scientific parts machining here. A single test fixture or a handful of sample holders is a normal order, with no minimum, quoted the same way a production run would be. For an iterative build, prototype CNC machining and small-batch CNC machining cover the next steps once the first part proves out.

Yes. Purchase orders are welcome and net terms are available for universities, national labs, and research groups. Send the PO number or your purchasing requirements with the files so the quote can be written against them. No C of C or material certifications ship with parts by default. If your PO needs them, say so before the quote. Inspection reports on critical dimensions aren’t included by default. If you need one, ask when you place the order.

Yes. Every quote includes a free DFM review: a real person reads your print and flags what will add cost and what may not work, such as tolerance, finish or fit issues, before you order. For experimental parts that have never been built, that second read comes before anything is made.

Standard work runs around ±0.005 in, and sealing faces, optical mounts and locating features are held tighter where the print calls for it. The tightest figures quoted are ±0.0002 in on wire-EDM and other finished features, and ±0.0001 in on ground features. Call out the critical fits on the print.

The material is your call and goes on the print. Published references give a starting point. Wikipedia says ultra-high vacuum systems use stainless steel rather than carbon steel, preferring non-leaded, low-sulfur austenitic grades such as 304 and 316. It says outgassing is minimized by low-vapor-pressure materials such as glass, titanium, certain 304 and 316 stainless steel and ceramics, and that plastics other than PTFE and PEEK are replaced with ceramics or metals (source 2). Moisture, sealants, lubricants and adhesives are the most common sources of outgassing (source 3), and NASA Goddard publishes a database of materials tested to ASTM E595 (source 4). Those grades have pages here: 304, 316, titanium and PEEK. Other alloys and plastics quoted on request. Name the grade on the print.

Any file type is accepted, and a STEP model plus a 2D PDF drawing is ideal. Mark the critical features on the print, such as sealing faces, optical seats and locating bores. Ask for more than one quantity, such as 1, 25 and 100, and the quote shows each. A fully dimensioned 2D PDF is quoted without a CAD line, and a sketch, photos or a new sample part start a quote with the CAD work quoted as its own line. The sample ships back with the parts. Lead time starts at order approval. Put your need date in the part description and the quote answers it.

This page is for R&D and scientific research: custom apparatus, test rigs, scientific instrument components, and lab equipment parts for test labs, university and national labs, and R&D groups. If you build or supply clinical devices and laboratory instruments, the medical and lab instruments page is the better fit. Either way, send the files and you get a quote in 24-48 hours.
