Produktübersicht
Produce high-quality power threads with our ACME Full Profile laydown threading inserts. Compliant with ANSI/ASME B1.5 standards, these tools generate the specific 29° trapezoidal profile required for American lead screws and jacks.
Featuring a “Full Profile” geometry, these carbide threading inserts cut the thread groove and finish the crest diameter in a single pass. This ensures the thread form is precise and burr-free, which is critical for minimizing friction in power transmission assemblies.
Wichtigste Merkmale und Vorteile
- Standard Compliance: Precision ground to maintain the 29° angle, distinguishing it from the 30° Metric TR standard.
- Der 16ER-Standard: Unser 16er-Gewindeeinsätze (3/8″ I.C.) efficiently handle the most common pitch range (16 TPI to 8 TPI) found in general machinery.
- Hohe Belastbarkeit: For coarser threads (6 TPI to 4 TPI), we utilize larger 1/2″ (22 mm) und 5/8″ (27mm) I.C. inserts to ensure tool rigidity.
- Richtungsoptionen: Wir bieten umfassende Lösungen, einschließlich Standard-Rechtshandwerkzeugen und Linksgewindeeinsatz models (e.g., 16EL 10 ACME) for bi-directional lead screw manufacturing.

Bearbeitungsrichtlinien
- Clearance Check: ACME threads have steep lead angles. Ensure your threading inserts for lathe holders have the correct shim (anvil) installed to prevent the insert flank from rubbing against the thread wall.
- In-Feed Method: For coarser pitches (e.g., 6 TPI or 4 TPI), use a modified flank in-feed (alternating flank) to reduce cutting pressure on the laydown threading inserts.
-
Stability: For pitches coarser than 4 TPI, please refer to our Heavy Duty U-Type series.
