Product Description

Product Description
High-rigidity Clamp Holding Structure & Precision Screws
High-rigidity clamp holding structure mechanism

The body and slide part are integrated with a hand-finished dovetail that is aligned to the actual workpiece and held fixed with clamp bolts. Since it is constrained in two places (the taper area of the dovetail and the bottom surface), a highly rigid assembly is ensured.

ABHs 18 to 50 employ polished micro adjustment screws that allow fine-tuning with a precision of 0.05 dia. by direct reading, and of 0.01 dia. using a vernier scale. ABHs 63 to 83/BHBs 125 to 180/BTMs 320 to 420 use polished worms/worm wheels, allowing fine-tuning with a precision of 0.01 dia. by direct reading.

Wide Variety of Blade Edges

These blades are designed so that blade edge damage will not immediately lead to body damage. ISO tips are used for all the products, allowing you to select the tips of any blade manufacturer for a specific workpiece.

Specifications
  • The shank is connected to the body by screwing-in.
  • This secure connection method ensures high rigidity.
  • A wide range of shanks is provided.
  • Recommended for semi-finishing operations. Can also be used for blind hole drilling, through hole drilling, crude machining, and finishing operations. Processing range is normal.

Frequently Asked Questions
What makes the clamp holding structure highly rigid?
The body and slide part are integrated with a hand-finished dovetail aligned to the actual workpiece and fixed with clamp bolts. Constraining the assembly in two places (the taper area of the dovetail and the bottom surface) ensures high rigidity.
What is the adjustment precision of these boring heads?
ABH 18 to 50 heads feature polished micro adjustment screws allowing fine-tuning precision of 0.05 dia. by direct reading, and 0.01 dia. using a vernier scale. ABH 63 to 83, BHB 125 to 180, and BTM 320 to 420 models use polished worms/worm wheels for 0.01 dia. direct-reading precision.
Are the blade tips compatible with other manufacturers?
Yes, our boring heads are designed to use standard ISO tips. This allows you to select and use tips from any blade manufacturer suitable for your specific workpiece.
Are throwaway tips included with the boring head package?
No, throwaway tips are not supplied with the product and must be purchased separately.
What operations are these boring heads recommended for?
They are highly recommended for semi-finishing operations. Additionally, they can be utilized for blind hole drilling, through hole drilling, crude machining, and finishing operations.
What are the available shipping options?
We offer flexible shipping arrangements to meet customer requirements, including sea freight, air freight, and overseas express couriers like EMS, DHL, and FedEx.
