Quick change lathe tool post with 40 angular positions – FERVI T00A

The quick-change lathe tool post T00A uses hardened and ground toothing for durability. An eccentric pin locks the holder onto the body. The system offers 40 indexed angular positions. Repeatability stays consistent through repeated tool swaps. The kit includes one turret, three flat-seat holders, and one prismatic holder.

Quick-change lathe tool post construction and locking mechanism

The body features hardened toothing machined to tight tolerances. The eccentric pin engages the toothing to clamp the holder. This design delivers fast, secure mounting without complex adjustments. The 40-position indexing divides the circumference into equal angular increments. Each position locks positively for stable cutting forces.

• Hardened and ground toothing on the body
• Eccentric-pin locking mechanism
• 40 indexed angular positions around the circumference
• Repeatable positioning after every tool change
• Positive engagement under cutting loads

The toothing geometry ensures the holder seats fully before the pin engages. Operators rotate the holder to the desired index and actuate the eccentric pin. The clamp force distributes evenly across the toothing. This arrangement minimizes runout and maintains alignment over time.

Technical specifications and included components

The T00A set comprises one tool-holder turret with 40-position indexing. Three flat-seat holders accommodate standard turning tools. One prismatic-seat holder accepts round-shank tooling. All components are machined for close fit. The hardened toothing resists wear during frequent changes.

• Number of angular positions: 40
• Locking method: eccentric pin
• Toothing treatment: hardened and ground
• Turret quantity: 1
• Flat-seat tool holders: 3
• Prismatic-seat tool holder: 1

Each holder mounts and dismounts without tools. The eccentric pin requires only a quarter turn to lock or release. The flat-seat holders suit most lathe tool geometries. The prismatic holder grips round or hexagonal shanks securely.

Repeatability and accuracy retention

The 40-position indexing maintains angular accuracy across repeated cycles. Hardened toothing resists deformation under clamping force. The eccentric pin applies consistent pressure at each position. Operators achieve the same tool orientation every time a holder is reinstalled. This repeatability reduces setup time and improves part consistency.

• Consistent angular positioning after every change
• Hardened surfaces resist wear and deformation
• Eccentric pin delivers uniform clamp force
• Minimal runout over extended use

The ground toothing ensures smooth engagement without backlash. Each index position locks with the same mechanical advantage. This design eliminates cumulative error from repeated tool swaps. Accuracy remains stable even after hundreds of changes.

Common applications in lathe operations

The T00A tool post suits production lathes requiring frequent tool changes. The 40-position indexing supports diverse cutting angles without manual adjustment. Workshops running mixed-part batches benefit from fast holder swaps. The system handles turning, facing, grooving, and threading operations. Both small-batch and high-volume environments gain efficiency from repeatable positioning and quick changeover.

Advantages of the eccentric-pin design

The eccentric pin simplifies the locking sequence. Operators rotate the pin a quarter turn to engage or release. No separate fasteners or adjustment screws are needed. The mechanism applies clamping force directly to the toothing. This direct path minimizes compliance and vibration. The design also reduces the number of wearing parts, lowering maintenance requirements over the tool post's service life.
