Overview

The Mazak MEGA TURN 1600 is the largest vertical turning center in Mazak's MEGA TURN lineup, built for machining extra-large workpieces up to 1,650 mm (64.96 in) in diameter and 900 mm (35.43 in) in height. This machine addresses the heavy industrial segment where workpieces are simply too large and heavy for horizontal lathes or smaller VTLs — think power generation turbine casings, large-bore valve bodies, mining equipment components, and shipbuilding forgings.

The vertical spindle orientation is essential at this scale. With workpieces potentially weighing 8,000-10,000 kg or more, the gravity-assisted loading of a VTL eliminates the dangerous and difficult task of side-loading massive parts into a horizontal chuck. The workpiece seats naturally onto the table under its own weight, improving concentricity and simplifying fixturing. Chuck sizes range from 1,250 mm (49.21 in) to 1,500 mm (59.06 in) depending on configuration.

The main drive delivers substantial torque for aggressive roughing on large-diameter castings and forgings in cast iron, carbon steel, and alloy steel. The machine structure is built for rigidity at scale — the bed, column, and cross-rail are designed to absorb the cutting forces generated when removing heavy stock from workpieces measuring over a meter in diameter.

The 1600M variant adds a milling spindle for drilling, tapping, and contour milling operations, which is particularly valuable at this scale since moving multi-ton workpieces to a separate machining center adds significant handling time, crane costs, and safety risk. The MAZATROL SmoothG CNC manages both turning and milling operations through conversational programming.

The MEGA TURN 1600 competes with the Hankook VTC-160, Toshiba TUE-200, and Okuma 2SP-V100 in the large VTL segment. New machines price between $500,000 and $800,000+ depending on configuration, milling options, and automation. Used units from 2015-2022 trade between $250,000 and $500,000.

Strengths & Limitations

Strengths

1,650 mm turning diameter handles extra-large castings, forgings, and weldments that exceed the capacity of the MEGA TURN 900 and most competing VTLs
Vertical spindle orientation makes loading multi-ton workpieces with overhead crane safe and practical, with gravity-assisted seating improving concentricity
Chuck sizes up to 1,500 mm accommodate the large-bore flanges, turbine casings, and ring forgings common in power generation and heavy industry
1600M variant with milling spindle eliminates the need to crane-transfer massive workpieces to a boring mill for drilling, tapping, and milling operations
MAZATROL SmoothG conversational CNC simplifies programming for large-part turning and milling cycles on a machine class where setup time is a significant cost factor
Rigid heavy-duty machine structure absorbs the cutting forces generated during aggressive roughing on large-diameter cast iron and steel workpieces

Limitations

Maximum spindle speed is relatively low (estimated 500 RPM), limiting the machine to large-diameter work where high surface speed is achieved through diameter rather than RPM
25,000+ kg machine weight requires substantial foundation engineering, specialized rigging, and dedicated floor space that many shops cannot accommodate
Overhead crane with sufficient capacity (10+ ton) is mandatory for loading and unloading workpieces, adding infrastructure requirements
Lead times for new MEGA TURN 1600 machines are typically 9-18 months given the specialized nature and build complexity

Best For

Power generation manufacturers machining large turbine casings, generator housings, and reactor vessel components over 1 meter in diameter Oil and gas companies producing large-bore valve bodies, wellhead components, and blowout preventer housings from heavy forgings Mining equipment manufacturers turning large bearing housings, crusher components, and gearbox housings from castings Shipbuilding and marine manufacturers machining propeller hubs, stern tube components, and large flanges Heavy equipment OEMs producing large structural rings, slewing bearings, and rotary table components

Frequently Asked Questions

01 What does a new Mazak MEGA TURN 1600 cost?

New MEGA TURN 1600 machines start around $500,000 for the base 2-axis configuration. The 1600M variant with milling spindle adds $80,000-$120,000. Full configurations with automation integration, probing, and enhanced chip management can reach $700,000-$800,000+. Used units from 2015-2022 trade between $250,000 and $500,000.

02 What is the difference between the MEGA TURN 900 and 1600?

The 900 handles workpieces up to 920 mm diameter with chucks up to 36 inches. The 1600 steps up to 1,650 mm diameter with chucks up to 59 inches. The 1600 is a significantly larger, heavier machine built for the extra-large workpieces found in power generation, mining, and shipbuilding. The price difference is roughly $200,000-$350,000 between comparable configurations.

03 What crane capacity is needed for the MEGA TURN 1600?

A minimum 10-ton overhead crane is recommended, though many shops running the 1600 have 15-25 ton cranes for the heaviest workpieces. The crane must have sufficient hook height to clear the machine and workpiece during loading. Some installations use dedicated gantry cranes positioned directly over the machine for efficient loading cycles.

04 Can the MEGA TURN 1600 handle interrupted cuts on castings?

Yes. The rigid vertical structure and heavy-duty spindle drive are specifically designed for interrupted cuts on rough castings and forgings. The vertical orientation also provides excellent chip evacuation since gravity pulls chips away from the cutting zone, which is important when machining sand-cast parts with porosity.
