For shops · Heavy VTL & large-diameter turning shops
Heavy VTL and large-diameter shops: 20" to 10 ft swing work, routed to you
The RFQs with 20 inch diameter 1020 bar, forged carbon-steel rings, and oversized flanges do not fit the prototyping-marketplace network. If your shop runs a VTL or a heavy horizontal lathe, we have the work.

The large-diameter work on our board
A sample of the oversize-turning RFQs we have been receiving. These parts are routinely declined by instant-quote marketplaces because they do not fit the standard CNC envelope.
Carbon-steel bar and forged billet, 20"+ diameter
- 1018, 1020, 1045, A36 forged rounds and ring-rolled rings
- Shafts, hubs, flanges, bearing housings for power-gen and heavy equipment
- Qty 1–20; finish turn, bore, face, and single-point thread features
Alloy steel heavy shafts and journals
- 4140 pre-hardened and 4340 bar to 18 ft long on heavy horizontal lathes
- Pump shafts, rolls, turbine shafts, mill rolls
- Stress relief, grinding, and in-process inspection expected on tight features
Stainless, duplex, and nickel-alloy rings and flanges
- 316, 2205, Inconel 625 forged rings for marine, chemical, and energy service
- Weld-prep, boring, and face grooves on O-ring glands
- NACE / sour-service documentation when the end use calls for it
Oversize aluminum and bronze turning
- Aluminum (6061 cast and wrought) housings 20–60 in in diameter
- Phosphor bronze and aluminum-bronze bushings for mining and marine
- Plate blanks pre-machined on the VTL for subsequent 5-axis work
What qualifies you
What a qualified heavy-turning shop looks like
- VTL swing / chuck size
- 24", 36", 48", or larger. Pit-mounted VTLs for 10 ft+ swing a bonus.
- Heavy horizontal lathes
- Big American, Kingston, Mazak Slant Turn, or equivalent with 20"+ swing over the ways and 10 ft+ between centers.
- Boring mill backup
- Floor-type or planer-type horizontal boring mills for faces, bores, and features too large for the VTL alone.
- Material sourcing
- Relationships with Charter, TimkenSteel, Ellwood, Scot Forge, Ulbrich, or equivalent mills for forged bar and ring-rolled rings. We often need you to source stock faster than the customer could.
- In-process inspection
- Portable CMM arm or template-based inspection on the machine; large-part layout and bluing when needed.
- Heavy rigging and shipping
- Overhead crane capacity and the dock to actually ship a 2000 lb part. We will not route a job your shop cannot physically load out.
- Secondary ops network
- Grinding, heat treat, plating, and weld-prep partners you already use. Not required in-house.
What you get
What a heavy-iron partner gets
Jobs priced like heavy work
We do not pressure VTL quotes into a 48-hour prototype turnaround. 4–8 week lead times are communicated to customers before you quote.
Free to join; no fees
No subscription, no per-RFQ fee, no commission. The customer pays us separately from your quote.
You see the real part
CAD, drawing, weight, material certs required, and the ship-to location before you commit.
Material sourcing paid up front
Where you source the forging or billet, that cost is passed through and paid before you cut.
Keep your own customers
Our RFQs are from hardware teams and buyers who found us, not from your book of business.
One-shop or network sourcing
If a job needs rough-turning on your VTL and precision grinding at a partner, we help coordinate rather than making you quote the whole thing.
