Davenport Machine

Davenport Machine offers new features for its HP machine. The controls package has moved to a more ergonomic position and comes prewired to the machine. The coolant pump is located off the floor, multiple emergency stops were added and an additional viewing window is now in place.

The Davenport HP multi-spindle machine rolls out its fourth major product enhancement to meet the evolving demands in high-speed machining. For easier interaction, the Man-Machine-Interface (MMI) has been mounted on a waist-high pendant system that allows the operator to use the interface at the front, end or back of the machine. The upgraded sound enclosure has more windows to increase visibility of the machine while it is running.

Davenport's High-Precision Orientation (HPO) attachment has the flexibility to eliminate the need for two of the most commonly used attachments: the 1380-SA Revinloc attachment and MBSL-200-SA 1800 spindle locating attachment (also the MB-2-SL-SA, 360-degree locator). This orientation optional attachment can be used in either the third or fourth position individually or both positions simultaneously. The HPO can be used to produce slots or flats on a part at 90 degrees apart (four tooth), 120 degrees apart (six tooth) and 45 degrees apart (eight tooth).

Davenport's High-Precision (HP) Machine comes fully loaded with a PLC for reduced setup times and a high-precision head as standard equipment. The HP head design has stiffened the machine revolving spindles by replacing bronze or needle bearings with ABEC 9 angular radial bearings. This improvement delivers spindle runout consistently less than 0.

The quick-change tool spindle front box from Davenport Machine was developed in conjunction with Davenport customers to cut hours off of every setup requiring a tool spindle change. The quick-change box allows the steel outer housing to be aligned and installed once, and interchangeable bronze liners can then be swapped in less than a minute. Changing from a stationary spindle to a revolving spindle or to a broaching spindle can be done without disturbing the spindle alignment.

For many high-volume applications, multi-spindle automatics are the right technology for production machining. Increasingly, that production efficiency has been pressured by changes in the needs of shops in the form of shorter run jobs and higher tolerances. This article looks at some of the steps one OEM has taken to address quick change-over issues on its multi-spindle machines and their tooling.

The New Davenport coated head shows zero wear after producing one million parts in a test run on a customer's machines, the company says. Now, the same extended wear life found on the HP revolving head is available on standard 8-SA heads with standard spindles. Using a metallic hard-coating material on the bearing diameter bands, the 8-SA head has less friction and less wear.

As with many manufacturers today, streamlining production to stay competitive in the global market has become increasingly important at this company. Thatýs why it sought out a machine to produce a double-ended pipe fitting in a single operation as opposed to having to do the back-tapping in an entire second operation.
