Large Part CNC Machining in Hayward with IMT Precision

Most machine shops are built around parts that fit in your hand. A few are built for parts that fill a pickup bed. IMT Precision is a Hayward shop listed here for large envelope CNC machining, with multi-axis milling, turning and boring, ultra high vacuum chamber fabrication, TIG and MIG welding, assembly and integration, and CMM inspection and helium leak testing, in aluminum, stainless steel, titanium and exotic alloys. The listing states travel of up to 201 by 134 by 42 inches. This page explains what large part machining involves and how to prepare a request.

What the envelope means

The envelope is the space a machine can cut within. The listing quotes up to 201 x 134 x 42 inch travel, which is about 16.75 feet long, 11 feet wide and 3.5 feet tall. A part bigger than the envelope cannot be machined in one piece, so check your overall dimensions against it. Include the longest dimension in your request even if the part is not yet final.

Why large parts are harder

Big parts are heavy and may flex when clamped. Metal also grows and shrinks with temperature, and a few degrees change can matter over a long length. Shops handle this with solid fixturing, careful sequencing and controlled measurement. Moving the part is a job in itself, so cranes and handling plans matter.

Multi-axis milling, turning and boring

Large parts often need features on several faces, such as bores, flanges and mounting surfaces. Multi-axis milling reaches many faces in one setup. Turning makes large round parts. Boring finishes large holes to accurate size and position. The listing names all three.

Vacuum chamber fabrication

An ultra high vacuum chamber is a sealed vessel from which almost all air is removed. Chambers like this are used in research and certain manufacturing processes. They need clean surfaces, tight welds and careful machining of sealing surfaces. The listing names the fabrication of such chambers, so a buyer with that need can start a conversation. State the size, the vacuum level you need and any cleaning standard.

Welding, assembly and integration

TIG and MIG welding join metal into frames and vessels. Assembly and integration bring several parts together into a working unit. For large systems, it can help to have one source doing both machining and assembly so the parts are built to fit.

CMM inspection and helium leak testing

A coordinate measuring machine checks dimensions by probing. Helium leak testing detects tiny leaks by filling a vessel with helium and sensing escape. The listing names both. If you need a leak rate, say what level you require and how it should be reported.

Materials

The listing names aluminum, stainless steel, titanium and exotic alloys. Large stock costs a lot, and mistakes are expensive, so confirm material and size early. Lead time for big plate or forgings can be long.

Quality listing

The listing notes ISO 9001:2015, as stated on the shop’s site.

What to include in your RFQ

• Drawings and 3D models with revision
• Overall size and weight
• Material and grade, and who supplies it
• Tolerances and critical surfaces
• Welding, cleaning or leak test requirements
• Delivery and shipping needs
• Required date

Local advantage

For parts this size, freight is a real cost. A Hayward shop reduces trucking distance for Bay Area customers.

Handling, shipping and timing

Large parts need a plan for getting in and out of the shop. Tell the shop where the part will be delivered, whether the receiving site has a loading dock or lift, and whether crating or special protection is needed. Also share your target date early, because large stock, long machine cycles and leak testing all take time. A realistic schedule built together at the start is better than a rush at the end.
