Heavy-duty 90° milling heads series A80 are built for rigid face and side milling on large CNC centers. The high-tensile alloy body provides solid dampening with oil and dust sealing. Precision spiral bevel gears with 1:1 ratio maintain stable cutting under rigorous machining operations.

Spindle taper options BT50, CAT50, SK50 and ISO50 for rigid heavy machining
Gleason ground spiral bevel gears operating at standard 1:1 speed ratio
High dynamic spindle balancing engineered for sustained continuous cutting duty
Replacement bevel gear pairs, P4 spindle bearings, ER40 collets and seals

Universal Adjustable Milling Heads Series A90

Universal milling heads series A90 provide versatile spindle angle adjustment from 0° to ±90°. The rigid swivel mechanism enables multi-angle face milling and drilling on reference planes without re-fixturing. Secure angular clamping ensures high dimensional accuracy during precision finishing.

Angular swivel adjustment range from 0° to ±90° with engraved precision scales
Integrated ER32 collet chuck accepting cutting tool shanks up to 20 mm
Spindle mounting interface compatible with BT40, BT50 and SK40 machine tapers

Automatic ATC Magazine-Exchangeable Milling Heads

Automatic angle heads by AHG are engineered for CNC machines featuring automatic tool changers. The lightweight assembly is stored in the standard tool magazine and loaded into the spindle by the ATC arm. A stop block and positioning pin secure torque transfer and cutting coolant delivery.

Full compatibility with CNC automatic tool changer arms and magazines
Lightweight high-strength alloy body equipped with heavy-duty stop block pins
Supports through-spindle and external nozzle coolant at pressures up to 20 bar
Replacement positioning blocks, drive keys, high-pressure seals, and pull studs

Semi-Automatic Hydraulic Angle Heads A85A / A86BG

Semi-automatic milling heads series A85A and A86BG feature hydraulic clamping and rigid positioning mechanisms. Units clamp directly to gantry machine rams via hydraulic plates or four pull-studs. Heavy-duty bevel gearing delivers steady torque during roughing and finishing on steel and cast iron.

Hydraulic clamping plate on A85A-A81-G and four pull-stud locking on A86BG
Heavy-duty bevel gear transmission delivering 1:1 ratio for gantry mills
Maximum transmitted torque up to 800 Nm under continuous roughing duty
Hydraulic clamping pistons, disc spring packs, hydraulic seals and lock studs

Deep Cavity Extension Milling Heads Series A65 / A75

Extension milling heads series A65 and A75 are engineered for deep pocket milling, cavities, and mold ribs. The rigid extended arbor with intermediate precision bearings minimizes tool runout during deep reach operations. The slim profile prevents collisions between machine ram and workpiece.

Extended body reach from 150 to 350 mm for deep cavities and complex molds
Precision spindle bearing arrangement maintaining radial runout within 0.005 mm
Tool holding collet options ER20, ER25 and ER32 for solid carbide end mills
Extended spindle arbors, intermediate bearings, dust covers and collet nuts

Compact and Mini Angle Milling Heads A74 / A77

Miniature angle heads series A74 and A77 are designed for internal bores and narrow cavities. The slim profile allows entry into bores down to 45 mm diameter. Precision spindle bearings support smooth cutting with ER11 and ER16 collets.

Ultra-compact profile entering bores and internal cavities down to 45 mm
High-precision spindle assembly engineered for high-velocity finishing
Miniature collet chucks ER11 and ER16 gripping tool shanks from 0.5 to 10 mm
Precision micro-bearings, miniature bevel gears, ER collets, and clamping nuts

90° Deep Boring and Facing Milling Heads Series A70

90° boring heads series A70 are purpose-built for deep internal boring and cylinder seat facing on horizontal boring mills. The reinforced cantilevered spindle structure maintains high rigidity under heavy radial cutting forces. The head mounts precision boring bars and adjustable facing tools.

Dedicated geometry engineered for deep internal cylinder boring and facing
Heavy-duty preloaded angular contact bearing sets resisting radial deflection
Spindle interface ISO40 / BT40 accepting micro-adjustable precision boring heads
Spindle shafts, boring bar adapters, adjustment wedges and maintenance seal kits

90° Twin Spindle Milling Heads Series A79

Twin spindle milling heads series A79 feature two opposing 90° spindle outputs driven synchronously. This dual-output layout enables simultaneous or sequential two-sided milling in a single setup. The balanced configuration cuts cycle times and reduces mechanical wear on machine tool slideways.

Two opposing working spindles equipped with BT40 tapers or ER32 collet chucks
Synchronized precision gear drive balancing torque across both output spindles
Symmetrical housing layout effectively counteracting parasitic cutting torsion
Dual output drive shafts, matched gear sets, spindle bearings and ER collets

AHG Precision CNC Milling Heads and Angular Spindle Attachments

Taiwanese manufacturer AHG Precision Industry Ltd. designs high-rigidity machine tool accessories engineered for vertical, horizontal, and bridge-type CNC machining centers.

The product lineup encompasses automatic tool changer (ATC) magazine angle heads, semi-automatic hydraulic clamping heads A85A and A86BG, and manual universal heads A90 with continuous adjustment from 0 to 90 degrees.

Equipping a 3-axis CNC milling machine with an AHG precision angle head enables comprehensive multi-sided machining of complex engine blocks, molds, and aerospace structural components in a single workpiece clamping setup, substantially improving cycle efficiency.

Spindle Interface Compatibility and Torque Transmission

Selecting an AHG milling head requires assessing the machine spindle taper standards, including BT30, BT40, BT50, CAT, SK, and HSK configurations, along with permissible input torque and continuous operational spindle parameters.

For narrow cavities and deep pockets, the A65 and A75 extension series eliminate clearance interference between the machine ram and workpiece fixtures.

All bevel gear sets are manufactured from case-hardened alloy steel with precision Gleason ground spiral teeth, providing smooth tooth meshing, low thermal expansion, and extended bearing service life under demanding heavy cutting conditions.
