Multi-Spindle Automatic Lathes, Material Handling, ISO 9001 2000
We offer multi-spindle rotary transfer technology, including Hydromat 16-station machines.
- We custom design and build machines around your family of components, so you get the benefits of the most efficient production at the lowest capital cost
- We can build inline, trunnion, or horizontal equipment
- Our latest 24-station design uses a Hirth-Ring index table for + 0002 inch accuracies
- Machines typically have from eight to 24 stations
- Costs 60% less than an equivalent purchased machine. This savings is passed on to you!
High-Volume, High Speed Manufacturing with Close Tolerances
Our primary niche is high-volume jobs that require machines to produce parts at close tolerances in sub-two-second cycle times.
- Volumes that start from 300K to 500K parts and into the millions fit us best
- We will be one of the lowest cost providers in the world if your part fits our capabilities
- To maintain our position in this competitive market, we continually focus on new and unique technologies to improve cost-control and expand our capabilities

Boost Your Accurate Weekly Output!
Our multi-spindle lathe department runs machines by Schutte, Gildemeister, and Euroturn. These world-class lathes are typically more than 20 times more accurate than our competitor’s machines.
- Our weekly output capability is enhanced because every lathe is equipped with an auxiliary bar loading machine, which can increase your output by more than 25%.
- The high-reliability of these lathes ensures each machine can produce in excess of 300,000 parts weekly!
Single-Spindle Lathes for Short & Quick Runs
Our single spindle CNC department consists of Citizen Sliding Headstock lathes.
- Our engineering team has developed unique attachments that reduce the cycle times on female contact pins by 25%.
- These machines are extremely versatile for short runs and quick set-up.
- We have equipped them with bar loaders and sensors for un-attended operation.
- Let us put our expertise to work for you!
State of the Art Precision Machining
“State of the Art” European Multi-spindle lathes outperform standard lathes in every respect:
- RPM’s – Our spindles are modern sealed designs, which can operate at 300% faster RPM’s, allowing Liberty to produce your part faster!
- Hirth Ring Index – All of our lathes are equipped with this geared location mechanism which enhances accuracy by twenty fold.
- Compound Slides – We can single point complex features such as lead screws or threads.
- Faster Idle Time – Less non-cutting time means more parts per hour!
- Isolated Independent Cams – Each cutting tool is cammed at its optimum feed rate. All cams are separated form the chip area to prevent random chips on the cams.
- Micrometer Adjustments – All tools are more easily changed and thus more accurate parts are produced with less down time.
- Servodrives – All of our lathes use servodrives to eliminate clutch slipping and the wearing of mechanical drive components.
- Synchronous Drives – As our lathes are 100% Synchronous we can use advanced attachments to eliminate secondary operations. These include polygon forming, thread milling, off center rotating drilling, back drilling and tapping, etc.
As a result of the above technology our lathes typically are producing components 24 hours a day at efficiency rates of 90% or better.
