Blank Fixture Plate for Rottler CNC Machines

Start your next custom fixture with the machine-side mounting already done. This billet aluminum blank is precision machined to fit the locating dowels in your factory Rottler headstock and tailstock and bolts directly to the fourth-axis (A-axis). The factory dowels locate the plate as it mounts, so your shop can machine just the workpiece-side features it needs.

At 28.25 inches long, this plate matches the length of our standard fixture plates.

Machine compatibility

• Rottler P69A, P69AHD, EM69P, and EM69HP with the compatible A-axis fixture
• Rottler F69ATC equipped with the Rock and Roll (R&R) trunnion fixture

Applications

Use the blank to build workholding for most V8 and four-cylinder heads by machining the pattern and clearances for your casting. The same plate can be machined for intake manifolds, plenums, valve covers, vise mounting, or other custom parts that fit its footprint.

Plate details

• Overall footprint — 28.25 × 8 in
• Approximate usable area — 23.25 × 8 in. This is a conservative planning estimate. Some machines leave more usable length depending on the headstock and tailstock setup.
• Thickness — 1 in nominal
• Material — Billet 6061-T6 aluminum
• Mounting — Pre-machined mounting features register on the factory headstock and tailstock dowels. The blank workpiece area gives you room to machine your own hole pattern, locating features, and clearance cutouts for a cylinder head or custom part.

• Manufacturing — Designed and machined in-house by Advance Machine Specialties in Fort Pierce, Florida
