The Davenport Hybrid Machine offers users precision and flexibility in their manufacturing efforts. Simpler setups, faster cycle times, and a conventional Computer Numerical Control (CNC) interface make it easy to integrate the Davenport Hybrid Machine into virtually any workflow. This five-spindle screw machine’s ability to hold tight tolerances with exceptional accuracy has been proven via rigorous testing.
Clients who utilize the Davenport Hybrid Machine can leverage capabilities such as:
- Angular trepan grooves
- +/- 0.0003″ lengths
- 020″ wall thicknesses
- 10 RMS seal faces
- Aerospace alloys
Davenport Hybrid Machine Features
The Hybrid Machine takes the best mechanical features of Davenport’s screw machines and integrates them seamlessly with the precision provided by advanced CNC technology. Features of this multi-spindle screw machine include:
Revolving Head on Bearings
The Hybrid Machine’s revolving head is mounted on preloaded, angular contact ball bearings. This provides exceptional accuracy and ensures consistent spindle positioning. This configuration does not require thrust ring adjustments or endplay, facilitating improved length control and reduced friction and wear. As a result, the Hybrid Machine boasts a longer than average service life.
New Tool Holders
We elected to integrate new tool holders into our Hybrid Machine to ensure ease of use for operators. The Davenport Hybrid Machine features a first- and second-position rigid integral mounting dovetail interface. Our setup ensures that all positions are high-pressure coolant ready and features a carbide insert for form, skive, profiling, and cutoff.
Our rigid integral mounting dovetail interface also allows for a fully-adjustable center height and taper. Clients may leverage the capability of the adjustable stop for tool positioning.
Short Indexing Time
The Hybrid Machine boasts a revolving head index time as short as 0.025 seconds. Many of our customers report 2-second part cycles being reduced to 1.85-second part cycles when using the Hybrid Machine. This increases productivity by fabricating up to 7.5% more parts per shift. Select models running bar stock less than 3/8″ may be able to operate on a specialized 0.25-second index.
New Machine Base
Our new and improved machine base has doubled the volume of coolant that the Hybrid Machine can hold. Our team managed this improvement with minimal machine envelope expansion. The machine’s mass increased by approximately 25%—roughly 2000 pounds. Integrated structural supports also help improve rigidity and machine dampening.
Superior Size and Process Control
We’ve improved the level of process control provided by the Hybrid Machine. Davenport users experience fewer outliers and lower PPM defect rates. These factors—in addition to tighter bell curves and higher CpKs—result in a superior return on investment. Many users see profit increases that far outweigh the cost of the initial upgrade.
Five-Spindle Screw Machine Capabilities
Multi-spindle screw machines are a variety of turning machine. They allow manufacturers to fabricate products quickly as they utilize multiple tools to cut numerous pieces of material simultaneously. The process relies on multiple spindles carried in a precision-machined drum, which typically rotate in a horizontal orientation.
The process conducts multiple operations in each rotation of the drum and each complete rotation produces a part. This results in an exceptionally efficient process. At Davenport Machine, our multi-spindle screw machine capabilities include:
- Cross milling
- Flat generation
- Cross drilling
- Thread rolling
- Keyway milling
- Thread milling
- Gear hobbing
