N75B Series Angular Head｜

Descriptions

The Gong Yang N75B Series Angular Milling Head is engineered to expand the horizontal and lateral cutting capabilities of vertical machine tools, cost-effectively converting vertical milling into horizontal operations to achieve versatile, multi-purpose machine flexibility. Featuring a compact footprint and ergonomic setup, the unit can be equipped with an optional mounting adapter/flange to enable full 360° rotational adjustment for precise cutter orientation, making it an ideal attachment for deep-pocket boring, slot milling, end-face trimming, and bevel chamfering across complex workpieces.

Engineered for dependable operational rigidity and extended wear life, both the spindle shaft and drive gears are precision-machined from high-grade chromium-molybdenum alloy steel, rigorously carburized, heat-treated, and precision ground. Fitted with precision ball bearings optimized for high-speed operation and light cutting duty, the N75B supports standard #50 spindle tapers and operating speeds up to 2000 RPM. Tool clamping options include a hydraulic power clamping system (for standard BT-#50 tooling) or a manual clamping drawbar mechanism (compatible with NT-#50 or BT tooling with pull studs removed). The spindle is designed strictly for clockwise (forward) cutting rotation—reverse rotation is dedicated exclusively to tapping and counterboring cycles and must never be applied to milling or drilling—ensuring long-term geometric precision and operational reliability.

Features

Could change machine to make vertical milling.
Volume is small, convenient operation, suitable to make complex of machine tools.
To install a Graduated Ring which can be regulated 360° to choose the direction of the milling cutter.
The processing suitable to inner boring and milling of slots, end face repair, and beveled chamfering, etc.
Gear and spindle are made of chromium molybdenum alloy steel, through quenching and precise grinding.
Bearing are use ball bearing, suitable for high-speed and light cutting.
The milling head can only tapping and screw socket process while reversing, can't cutting and drilling or other process, make machinery damaged.
Two type of cutter locked for customer demand. The suitable cutter locked can be ordered and delivered together with the product when purchase.
(A)Hydraulic tool release for BT-#50 type.
(B)Screw tool release for NT or BT type. (Pull studs must remove for BT type)
