Overview
The Davenport Model E CNC is the enhanced, purpose-built CNC evolution of Davenport's iconic five-spindle multi-spindle platform. Where the Model B CNC typically represents a retrofit of an existing cam-driven machine, the Model E was engineered from the outset as a full CNC machine — with servo-driven axes, a modern electrical architecture, and an expanded feature set designed to meet the production demands of 21st-century precision manufacturing. Built by Brinkman International, the Model E retains the proven five-spindle layout and compact footprint of the Model B while delivering significantly higher axis count, faster cycle times, and expanded tooling capacity.
The Model E's enhanced CNC architecture includes servo-driven cross slides and end-working units at all five spindle positions, plus additional CNC axes for rear-working operations and optional driven tool positions. The machine supports up to 32 CNC axes in full configuration, enabling complex parts with cross-drilled holes, milled flats, and backside machined features to be completed in a single machine cycle. This capability closes the gap between the Davenport platform and more expensive European six-spindle machines on complex part families.
Davenport's control system on the Model E is based on a FANUC 0i-TF CNC platform with a proprietary Davenport multi-spindle programming overlay that simplifies cycle development for the five-position layout. The control includes an integrated part program simulator that allows programmers to verify all axis movements and tooling before executing on the machine, reducing first-part scrap and setup time. Remote diagnostics are supported via secure internet connection to Davenport's factory service team.
The Model E's enhanced coolant system supports through-tool high-pressure coolant at pressures up to 70 bar, significantly improving tool life and chip management versus the lower-pressure systems found on older Model B retrofits. The machine includes a modern safety enclosure that meets OSHA and ANSI B11 standards, integrated chip conveyor, centralized automatic lubrication, and a bar stock monitoring system. Brinkman International provides factory training programs at their facility, and the Model E carries a comprehensive parts and service warranty backed by Davenport's extensive North American dealer network.

Strengths & Limitations
Strengths
- Purpose-built CNC architecture with up to 32 axes delivers significantly more capability than Model B retrofit machines
- 42 mm bar capacity expands the Model E's part family range beyond the 38 mm limit of the standard Model B
- 8,000 RPM maximum spindle speed enables aggressive cycle times on small-to-medium diameter parts in steel and aluminum
- 70-bar through-tool high-pressure coolant dramatically improves tool life and chip control versus older Davenport platforms
Limitations
- Five-spindle layout still caps operation count per cycle versus six- or eight-spindle European alternatives for very complex parts
- Price premium over a quality rebuilt Model B retrofit requires volume justification — shops with lower annual throughput may find the Model B CNC more economical
- FANUC-based control with proprietary Davenport overlay may require additional training for programmers familiar with European Siemens-based multi-spindle systems

Frequently Asked Questions
01
The Model E's key upgrades over a retrofit Model B include: a larger 42 mm maximum bar diameter (vs. 38 mm), higher 8,000 RPM spindle speed, 70-bar high-pressure through-tool coolant (vs. 40–50 bar on most retrofits), up to 32 full CNC axes (vs. typically 12–18 on retrofits), and a purpose-built CNC architecture versus a cam machine conversion. The Model E is also covered by a factory warranty from Brinkman International, unlike most third-party retrofits.
02
Yes. The Model E supports driven (live) tool units at cross-slide and end-working positions. This enables milling of flats, slots, and hex features as well as cross-drilling at any angle relative to the spindle axis. These capabilities allow the Model E to complete parts that would require secondary operations on a standard turning multi-spindle, significantly reducing total cost per piece.
03
Thirty-two CNC axes sounds complex, but Davenport's proprietary programming overlay on the FANUC 0i-TF control presents the machine in a logical five-position structure that experienced Davenport programmers find intuitive. The overlay includes automatic axis synchronization and collision detection. New programmers with FANUC experience typically require 40–80 hours of dedicated Model E training to become productive on straightforward parts.
