Overview

The Mazak FJW-100/160 is a double-column, five-face machining center built for heavy cutting on large workpieces that most vertical mills cannot touch. With a 4,000 x 2,000 mm (157.5 x 78.7 in) table and 2,650 mm (104.3 in) between columns, this machine handles structural steel, mold bases, energy sector components, and anything else that needs multi-face access in a single setup.

The spindle runs through a CAT 50 taper at up to 6,000 RPM, producing 828 Nm (611 ft-lb) of torque at 40% ED with 37 kW (50 hp) of power. That is enough grunt for heavy face milling and boring in cast iron and steel. The standard angle head attachment indexes to 72 positions every 5 degrees, letting you reach features on all five faces without refixturing. On large prismatic parts that would otherwise require multiple setups on a horizontal boring mill, the FJW saves hours of crane time and alignment per part.

Axis travels measure 2,500 mm (98.4 in) on X, 1,650 mm (65.0 in) on the column height (Y), and 800 mm (31.5 in) on Z, with a W-axis cross rail lift adding another level of positioning flexibility for tall parts. Rapid traverse hits 20 m/min (787 ipm) on linear axes. The machine ships with a 40-tool ATC and runs on the MAZATROL SmoothG control with touchscreen interface.

At roughly 45,000 kg (99,200 lb), the FJW demands serious floor preparation and rigging. This is not a machine you move around the shop. Pricing for new FJW configurations runs $600,000 to $900,000 depending on options. It competes with double-column bridge mills from Toshiba, Okuma, and SNK in the large-part five-face machining segment.

Strengths & Limitations

Strengths

Five-face machining capability with standard angle head eliminates multiple setups on large prismatic parts, cutting cycle time dramatically on mold bases and structural components
4,000 x 2,000 mm table handles workpieces up to 15,000 kg, covering virtually all large-part applications in energy, construction, and heavy equipment
CAT 50 spindle with 828 Nm of torque drives aggressive face milling and boring in cast iron and steel without backing off feed rates
Double-column bridge construction provides superior rigidity compared to C-frame designs, maintaining accuracy across the full work envelope
MAZATROL SmoothG control with touchscreen simplifies programming of complex multi-face operations with both conversational and G-code capability
W-axis cross rail lift adds vertical positioning flexibility for accommodating varying part heights without compromising Z-axis stroke

Limitations

At 45,000 kg, installation requires significant floor preparation and rigging, making relocation a major undertaking
6,000 RPM maximum spindle speed limits high-speed finishing on aluminum; shops running predominantly non-ferrous work should look elsewhere
Standard 40-tool ATC is relatively small for a machine of this size; complex multi-face jobs may require manual tool changes or magazine upgrades
20 m/min rapid traverse is slow compared to smaller machining centers, adding non-cutting time on large-envelope moves

Best For

Mold base manufacturers machining large die and injection mold components requiring five-face access in a single setup Energy sector shops machining turbine housings, valve bodies, and large structural components in cast iron and steel Heavy equipment manufacturers processing large weldments and fabricated frames that exceed the capacity of standard VMCs Job shops specializing in large prismatic parts where five-face capability replaces multiple setups on horizontal boring mills Aerospace subcontractors machining large aluminum structural panels and frames requiring precise multi-face features

Frequently Asked Questions

01 What does a Mazak FJW-100/160 cost?

New FJW-100/160 machines typically price between $600,000 and $900,000 depending on spindle configuration, tool magazine capacity, and optional accessories like probing and high-pressure coolant. The angle head is included standard. Used FJW machines are uncommon on the secondary market but when they appear, expect $200,000 to $450,000 depending on vintage and condition.

02 What is five-face machining and why does it matter?

Five-face machining means the machine can access the top and all four sides of a workpiece in a single setup using the angle head attachment. Without five-face capability, you would need to reposition and re-datum the part multiple times. On large parts weighing thousands of kilograms, each additional setup adds hours of crane time, alignment, and quality risk.

03 How does the FJW compare to a horizontal boring mill?

The FJW handles similar work to a floor-type horizontal boring mill but with a fixed table and moving gantry. The double-column design provides more rigidity than a single-column boring mill on shorter-reach operations. However, horizontal boring mills typically offer longer X-axis strokes. The FJW wins on five-face versatility and setup efficiency.

04 What foundation does the FJW require?

At 45,000 kg, the FJW requires a reinforced concrete foundation engineered for the specific machine loads. Mazak provides foundation drawings with anchor bolt patterns during pre-installation. Budget $30,000 to $80,000 for foundation work depending on existing floor conditions.

05 Can the FJW run unattended?

The FJW can run unattended during long single-face operations with appropriate tool life management and coolant monitoring. However, five-face work often requires angle head changes and part repositioning, which typically involves operator presence. Expanding the tool magazine to 60 or 80 positions extends unattended capability.
