HB Series

Horizontal Machining Center

High rigidity structure! Realize the high efficiency in heavy-duty machining.


High rigidity structure

  • Column with dual-layer wall structure design

  • Three axes adopt high rigidity roller guideway

  • Through the finite element analysis (FEA) to ensure the machine structure to qualify the features of high dynamic rigidity and stability in high speed

Full-circumference hydraulic braking system (for NC 0.001° indexing)

The full-circumference hydraulic braking system uses the oil pressure to lock the entire disc synchronously. Because of its large locking area, it has high rigidity and can withstand heavy cutting.

Bulit-in spindle

Ø100 mm ceramic bearing are aligned in 10,000 rpm standard built-in spindle in HB series. Chilled cooling fluid is recirculated through the spindle cartridge and compressed air is led into the motor for cooling. It generates 420 N m torque at 500 rpm, especially suitable for the heavy duty cutting in cast iron or steel materials.

Max. spindle speed : 10000 rpm

Spindle motor power : 30/25 kW

Output torque :  420/350/238 N m (25% ED/10 min./Cont.)

High torque spindle with gear box (HB-630II/HB-800II)

Adopts high quality gears for high transmission
efficiency. The two-step gear box can generate
more than 1,000 N m torque at 200 rpm, especially
suitable for tough materials and large parts.

Max. spindle speed : 6,000 rpm
Spindle motor power : 22/18.5 kW
Output torque : 1,050/883 N m
(30 min. S3, 60%/Cont.)

Coolant through spindle (C.T.S.)

C.T.S. system increases the efficiency of chip removal and extends the tool life by cooling its cutting point.

Discharge pressure: 20/40/70 bar (2.0/4.0/7.0 MPa)

Filtering accuracy: 40 μm

Automatic pallet changer (APC)

The latest APC hydraulic driving unit improves dynamic rigidity and optimizes the PLC settings. Under the situation of maximum loading in both sides, the exchanging time is decreased dramatically.

Automatic tool changer (ATC)

Equipped with Japanese made cam type ATC.


Hydraulic and pneumatic supply for jig & fixture (optional)

Use quick couplet to connect with the pallet and the hydraulic oil is supplied under the pallet. Once pallet changes, the quick couplet will separate. It solves the problem of twisted pipes and benefits B axis rotation.
