Bolt threading machine

Product overview
Bolt Threading Machine for cutting external threads on stationary jobs using tangential HSS chasers. The die‑head rotates while the workpiece remains fixed, enabling accurate production of BSW, UNF, METRIC, UNC, ACME, BSP, BSPT, NPT and other thread forms suitable for industrial applications.

Components

• Base
• Head stock
• Saddle
• Bed or pillar type clamping vice
• Die‑head

Head stock
Rigidly constructed from forged alloy steel for long‑term alignment with carriage ways; shafts are heat‑treated alloy steel for increased durability.

Saddle
Precision fitted on two pillars to ensure smooth, accurate travel aligned with the head stock center for consistent thread engagement.

Apron
Transfers motion to the saddle using a steel rack and robust gearing. Gears are manufactured from high‑grade steel to ensure reliable power transmission.

Vice jaws
Heavy‑duty box‑type vice with hardened alloy steel jaws, heat treated and screw‑driven for controlled clamping movement aligned to the head stock center.

Notes
The machine uses HSS tangential chasers as cutters. The stationary workpiece combined with rotating die‑head produces fine, repeatable external threads. Thread forms available depend on the set of chasers supplied.
