The new Davenport HYBRID is the next generation of Davenport Multi-Spindle machine tool technology. It incorporates the best of the mechanical versatility you have come to expect from Davenport, and adds to it the CNC Technology you need to address today’s most difficult manufacturing challenges.

The HYBRID is a super-precise machine platform.  It leverages the power of an intuitive CNC interface to make operation and set-ups easier than ever. With digital size control, CNC single point threading and turning capabilities, the HYBRID can hold tolerances never before produced on a Davenport.  It does so while delivering a superior Return On Investment for your capital equipment dollars.


The Davenport HYBRID was developed specifically to address, and provide answers to some of the industry’s toughest challenges.

  • Tougher Materials – aerospace alloys, stainless steels, high strength pre-hardened steels
  • Tighter Tolerances – increasingly tight part requirements, along with tougher to machine materials, have pushed many cam-operated machines beyond their capabilities to consistently produce parts made within the print requirements
  • Smaller Job Sizes – require more frequent machine changeovers, that must be done quickly and efficiently, or risk eroding profits, or worse, creating losses
  • Changing Workforce – experienced operators retiring at a rapid rate are being replaced by a new generation of operators starting out with an entirely different skillset. With reduced in-house training programs, and demands to shorten the learning curve for new operators, companies are faced with a real problem

The Davenport HYBRID brings real solutions to these pressing issues.

Goal Driven Design

Our design philosophy started with identifying the end goal. In this case, increasing profitability and productivity for our customers. With that in mind, we started on a multi-year effort to evaluate each and every system on our machine for performance, and identify where we could make mechanical improvements. We then targeted the application of CNC technology, and state-of-the-art motion control, to areas that would maximize the benefit without significantly increasing the cost or complexity. The HYBRID is an optimal blend of CNC and cam-operated mechanical motions. Many machine functions are still mechanical, because it is the most robust and cost effective means of making precision parts. Profits and productivity, thru innovation, has guided every HYBRID design decision, and that is what separates this machine from the competition.

Preventative Maintenance and Troubleshooting for Multi-Spindle Screw Machines

Screw machines simultaneously cut materials using a number of tools mounted on a spindle, yielding small final pieces. At the heart of these machines is a drum that operates multiple spindles, each of which rotates horizontally to perform tasks on the workpiece.

These machines can perform a number of operations on the workpiece within one rotation. They consist of many intricate parts, which perform complex tasks through the use of automated systems.

As such, it’s important to regularly troubleshoot and maintain multi-spindle machines to ensure smooth operation within your facility. Keeping your machinery cool, lubricated, and in good repair means less costly downtimes and higher degrees of accuracy in your manufacturing processes.

Set Up a Troubleshooting Checklist

Multi-spindle machine operators must ask themselves a number of questions to ensure their machines are in proper working order:

Is the Form Tool Diameter Changing in Size, Varying, or Chattering?

Check that the tool’s setup and head positioning maintain maximum rigidity. Then, look for any sloppy work spindle bearings and make sure that the tool has the proper center height setting. Verify the proper grind of your tool and check to see whether it’s properly supported during cutting. Look for a loose slide or tool, and make sure you tightly fasten all the bolts. Lastly, check for dull tools and make sure you’re working with the correct stop screw pressure.

Is the Hole too Big?

Verify that the machine is locking the head in the proper position, and check for sloppy spindles as these could signify off-center or chipped center drills. Next, check whether the drill is dulled or loaded up, and make sure the drill and spindle are properly aligned.

Is the Machine Stripping Threads?

Make sure the head’s locked properly, and verify that you’re working with the correct hole and body size. Look at the alignment of the spindle, and check for dull/loaded taps or dies. Finally, check the summary settings to make sure you’ve found the problem.

Does the Length Vary?

Many issues could cause variations in length. Most commonly, worn or sloppy bearings in the spindle or dull-end working tools can push work back into collets. Generally, loose, worn, or dirty collets can cause problems, and you may need to check for the proper feed finger tension on the five spindles.

At the bar end, check for a clean cutoff, and make sure the stock stop is tight, polished extensively, and at the right length of the stop plate. Feed the stock to the stock stop if this isn’t already the case. You should also check head thrust bearings as well as the rolls and pins on the end working cam lever for wear and tear.

Do the Parts Have Burrs on the Cutoff?

Evaluate the stop collar to make sure it has the proper pressure, and make sure the pickoff collet is adjusted properly. See if the cutoff is on center, and check the timing of the closing dog.

Is the Box Tool Dimension Rough or Varying in Size?

The box tool should have a proper grind and feed, so check for these first. Then, make sure the rollers have the proper tension.

Is the Hollow Mill Dimension Rough or Varying in Size?

Verify that the machine achieves the proper grind, and check for worn or loaded cutting edges. Then, look for the proper alignment and feed.

Has an Improper Step or Shoulder Appeared?

First, look at the form tool alignment and the box tool alignment, and then make sure the box tool has an appropriate travel distance. Evaluate the sharpness of the drills and verify that they reach the proper depth. Finally, check for any loose tools or holders.

Are the Rolled Threads Out of Form or Flaky Like the Scissor Type?

Look at the work’s feed or penetration, and check for the proper blank size. See if the blank has a taper, check whether the rolls are on the center of the work, and look for proper roll synchronization. Finally, check rolls for any nicks.

Is the Reamer Chattering?

It’s possible that there might be too much clearance on the spiral relief. You should also check to see whether it’s out of alignment. Make sure the feed is the right size for the particular reamer you’re using, and find and fix any low cutting edges.

Is There Tap Trouble?

If the tap’s cutting below the correct size, you might need a different tap for the job. The tap also must align with the workpiece. Look for proper float in the holder, and check to make sure that the hole’s of the proper size. Finally, check the summary settings.

Is the Knurl Out of Form or Flaky?

Make sure your blank’s the right size, and check both works’ feed and penetration. Look for taper on the blank, and check the knurl pins and the knurls themselves for signs of wear or nicks.

Preventative Maintenance For Multi-Spindle Screw Machine Services

Multi-spindle machines require comprehensive maintenance schedules. While you should perform some tasks daily, other processes require quarterly or yearly checkups.

Daily Maintenance

Make sure you have sufficient lubricating oil levels in the lube pump reservoir. Then, check the machine pan reservoir’s coolant level. It may be necessary to clean the coolant intake pipe screen or pump screen, so check this as well. Make sure the stock reel and its support are in good condition and aligned, since they should be lagged to the floor. Finally, verify that the machine is properly delivering lubricating oil to the work spindle bearings.

Monthly Maintenance

Once a month, take each of these items off the revolving head, clean and inspect them, and replace them if needed:

  • Collets/chucks
  • Feed tubes
  • Feed fingers (also make sure they’re appropriately tensioned)
  • Inner spindles

Then, check on the wear and tear and general condition of the following parts:

  • Stop screws
  • Cross slides
  • Gib adjustments
  • Stock reels and stands

Clean the outer spindles with a boiler brush, and make sure the locating lever is locking correctly and that the roll turns. Check the condition of the following components:

  • Chuck slides, rolls, and pins
  • Cam levers, rolls, and pins
  • Bearings
  • Tooth wear
  • Gear mountings

The shafts are particularly important: check for a potentially twisted front cam shaft, since the locating lever must clear the locating blocks on index, and you want it to make contact, angle side first, with 0.012” pushback when locking.

Check to see whether the revolving head has end play, and adjust the thrust ring if needed. Lastly, make sure that the locking nuts and set screws on the spindle change gear shafts are in good repair.

Quarterly Maintenance

Once every quarter, clean the coolant pan: remove all coolant and get rid of any sediments and fine chips before adding new coolant. If you have long runs that make changing the cams difficult, take the cross slides off and clean them before checking for proper gib adjustments. Remove the plugs at the bottom of the worm gear housing, and flush the housing with an OSHA-approved solvent. Finally, replace the plugs, and fill with fresh oil.

Semi-Annual Maintenance

Twice a year, drain, clean, flush, and refill the main lube pump reservoir. Check the filter, and make sure there isn’t excessive end play in the revolving head or thrust bearings. You should also verify that there’s no excessive looseness in the work spindles or tool spindles.

This is also a good time to check the condition of the electrical controls, including the switches, solenoid valves, wiring, panel box, cables, motors, and other elements, but make sure that only authorized personnel handle electrical control maintenance. Check pneumatics as well, including the air lines, valves, cylinders, and fitting.

Annual Maintenance

Once a year, perform a thorough inspection and cleaning of the entire machine as a unit. Check the tool spindles to ensure proper alignment with the work spindles, and align special attachments to the work spindles as needed.

Check for any cracks or breaks in the cross slides, and make sure all levers, rolls, and pins are in good condition. Check the chip conveyor’s condition as well as the condition of all the lubricating and coolant systems, including the:

  • Lube pump
  • Coolant pump
  • Lube lines
  • Meter units
  • Coolant screens
  • Coolant hoses/valves

Safety Matters! Pneumatic Collet Chucking for Davenport Machines

The 1605-SA Pneumatic Collet Chucking unit is an update to the classic lever operated chucking mechanism. On machines equipped with pneumatic control systems, the addition of this unit can be a great way to improve the user experience and remove a possible source of error. On standard lever actuated chucking mechanism, operators have to hit the lever repetitively throughout the course of a job to load bars and set collet tension. The pneumatic system can be used to open/close the collet during bar loads to lessen operator fatigue, and remove a means of direct operator to machine interaction. The use of pneumatics allows for easy pushbutton operation as opposed to repeatedly hitting the lever open or closed. The 1605-SA includes mounts, modified lever, control valve assembly, and other necessary hardware to connect the unit to the electrical/pneumatic systems.

Key Features:

  • Eliminates need to manually close chuck, switches action from lever to push button.
  • Improves setup time and minimizes recurring problems

Safety Matters! Improvements Made to Machine Enclosure with Door Interlocks

The Davenport Screw Machine enclosure has recently undergone a variety of improvements to enhance the overall user experience, as well as to bring the machine into compliance with modern safety standards.  With improved noise abatement and the addition of the door interlock system, the enclosure now offers a safer, code compliant working environment for the operator. Other changes to lighting, visibility and the wiring layout combine to add value to what is now standard for many new enclosure configurations. New HP machines come standard with the door interlock system and updated enclosure. Machines with enclosure model DSM-2000 and newer are compatible with the interlock system. If the enclosure model is DSM-85 or DSM 90 XL, it will require an enclosure upgrade to use interlocks. Depending on machine configuration, the interlock system may need auxiliary components in order to work properly.

Key Benefits of an Updated Enclosure, and Door Interlocks:

  • LED light upgrade, with more protection for lighting and longer working life
  • Large windows in 4 doors is standard in new enclosures, for better machine visibility

Types and Advantages of CNC Machines (Computer Numerical Control)

A CNC (or Computer Numerical Control) machine is an electro-mechanical device that uses computer programming inputs to operate machine shop tools. CNC machining is one common way to create prototypes (the other method being 3D printing).

While there are advantages to both, CNC is faster and stronger as it involves creating something new out of an already solid material. CNC machine programming offers many production advantages over previous methods of machining and is an indispensable tool across many industries.

How CNC Machines Work

Running on a set of prescribed digital instructions, CNC machines use computer files to execute a project. These digital instructions are created in either Computer Aided Design (CAD) or Computer Aided Manufacturing (CAM) files.

Once the program is uploaded, an operator runs a test program, often referred to as “cutting air.” This trial run is an important first step to verifying both speed and tool position because any discrepancies can result in damage to the machine or the part being created.

To maximize efficiency, CNC machines combine multiple tools into common cells or units. They produce the desired end product by removing material from the original stock source. This results in a stronger, more durable finished product.

The Two Types of CNC Machines

Conventional Technologies

  • Drills – These operate by spinning a drill bit and cutting it into a block of stock material.
  • Lathes – These are the opposite of drills. They spin the stock material against the drill bit instead of spinning the bit and cutting into the block.
  • Milling Machines – These use revolving cutting tools to remove material from the block. They are the most common type of CNC machine used today.

Novel Technologies

  • Electrical Machining – This highly specialized technology is common in special cases for mass production that use a certain type of material.
  • Other Mediums – Examples of this CNC machining technology include water-jet cutting, plasma cutting machines, and laser cutting machines.

Advantages of CNC Machines

  • They can run for 24 hours a day.
  • They can product jobs with higher accuracy and precision than other manual machines.
  • Operators can make changes easily, which reduces the delay time.
  • Fewer workers are needed to operate these machines, which saves labor costs.
  • CNC machines have the capability to create complex designs with high accuracy in a short amount of time.
  • The modern design software for CNC machines removes the need of producing a prototype or model before executing a project, which saves money and time in the long run.

CNC machining is vital part of many industries, such as aerospace, medical, automotive, and mining. Davenport Machine brings 100 years of innovation to each project, so every client has a product that meets their specifications and industry standards.

How Multi-Spindle Screw Machines Work

Multi-spindle screw machines are turning machines that use a number of tools mounted on a central spindle to simultaneously operate on material pieces. A precision-machined drum carries multiple spindles while typically rotating horizontally. To complete a part in one full rotation of the drum, the machine automatically divides the total number of operations between the spindles. With one part completed per drum index, multi-spindle screw machines deliver a highly efficient production process.

Basics of Multi-Spindle Screw Machines

All multi-spindle screw machines include accurate and rigid spindle-carrying heads. New machine models use angular contact radial bearings in the place of bronze or needle bearings, reducing runout for spindles to consistently less than 0.0005 in.

Davenport Machine’s multi-spindle screw machine capabilities include:

  • Forming
  • Backworking
  • Drilling
  • Reaming
  • Broaching
  • Cross milling
  • Flat generation
  • Cross drilling (drilling multiple holes at varying timed positions)
  • Thread rolling
  • Shaving
  • Swaging
  • Stamping
  • Burnishing
  • Keyway milling
  • Slotting
  • Thread milling
  • Gear hobbing

Parts of a Multi-Spindle Machine

Multi-spindle screw machines consist of three main components: the multi-spindle drill head, multi-spindle drill head attachment, and either a single or automatic multi-spindle lathe.

Multi-Spindle Drill Head

Multi-spindle screw machine drill heads typically contain numerous spindles mounted on ball bearings and driven by gears. The distance between the drill head’s spindles governs drill head bearing choice.

Multi-Spindle Drill Head Attachments

Multi-spindle screw machines incorporate fixed and adjustable drill heads.

  • Adjustable drill heads allow the drilling spindle’s center distance to vary according to specific requirements.
  • Fixed drilling heads have invariable center distance, allowing more precise drilling.

Multi-Spindle Lathe

A lathe rotates worked material on its axis to facilitate performance of operations including cutting, deformation, and turning. It operates by applying tools to the worked material as the lathe spins.

Mass production prefers multi-spindle lathes because they boost production rates four to six times greater than a single lathe machine.

Multi-Spindle Automatic Lathe

Automatic lathes for multi-spindle screw machines perform a range of operations, including:

  • Turning
  • Chamfering
  • Threading
  • Grooving
  • Boring holes
  • Drilling

These processes operate by moving the worked piece between the screw machine’s six to eight positions.

Types of Multi-Spindle Screw Machines
