BH20Z

20 mm High Performance Gang/Turret Turning Center

Tsugami BH20 Swiss Type CNC Lathe with Turret and Gang Type Tooling


Heavy Duty, Efficient Machining of Complex-Shaped Workpieces

Tsugami’s BH20Z Gang/Turret Turning Center combines the precision, accuracy, and speed of a high performance Swiss Type Lathe with the flexibility and additional rotary tool capability of a turning center with a turret.  In this unique combination, up to 35 tools on the tool posts (front gang and rear turret) combine to machine complex parts in single setup.  

The BH20Z is an extremely rugged, powerful (main and sub spindles) machine that can perform 7 different types of simultaneous machining involving the front, back, and cross spindles. A Fanuc 31i-A CNC control is standard.  If you need a heavyweight performer to make short work of heavy milling, turning, drilling, tapping, hobbing, and long thread whirling, the BH20Z is the right choice.  

Key Advantages include:   

  • Z-Axis Capability Added to Rear Turret, makes balanced turning, long thread whirling, and other options possible

  • Gang Tool Post + Turret + Dedicated Back Tool Post = Expanded Tool Options

  • Multiple Simultaneous Machining Options on front, back, and cross spindles make complex parts in one setup and slash cycle times

  • Independent Turret Drive improves accuracy and power, reduces thermal distortion

  • Excellent Rigidity and Thermal Characteristics due to Tsugami fine-ground cast iron base.

  • Powerful Back Spindle Motor: 2.2 /3.7kW

  • Fanuc 31i-A 3-path CNC drastically shortens cycle time  

The BH20Z turning center is CONVERTIBLE and may be run as a traditional sliding headstock Swiss Type Lathe using the guide bushing or run without the guide bushing with the addition of an optional chucker kit.

Convertible

BH20Z - Convertible

The BH20Z may be run as a traditional Swiss style lathe using the guide bushing. A quick, easy-to-change (10 minutes) optional “chucker” kit allows you to run the machine without a guide bushing. This is typically used for parts with a length-to-diameter ratio less than 3:1, a significant percentage of small parts.

By being “convertible”, the machine increases the shop’s flexibility to manufacture all types of small parts with speed, accuracy, and precision. Additional benefits to running without a guide bushing: much smaller remnants, ability to use ground bar stock, and faster speeds and surface finishes.
