Safety Matters! Pneumatic Collet Chucking for Davenport Machines

Leave a Comment

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 […]


Safety Matters! Pneumatic Collet Latch System for Davenport Machines

Leave a Comment

The 5020-20-SA is a member of a series of parts designed to make functions of a traditional Davenport Machine more accessible from the outside of an enclosure. Increasingly strict safety standards require more operations to take place behind walls of enclosures and integrated door interlock systems to keep users safe. This collet latch system enables […]


New Improvements Made to the Needle Bearing Locating Lever Stud Assembly

Leave a Comment

This is an update to our standard 5080-34-1-SA Locating Lever Assembly. The new assembly features precision needle bearings in place of the older tapered bronze bushing design. The old design required intermittent adjustments in order to keep the locating lever stud tight. If the bushings weren’t adjusted correctly, the revolving head index would vary, or […]

High Precision Chucker Brings Versatility to Secondary Machining

Leave a Comment

Secondary operations can often be time-consuming and cost prohibitive. Many shops invest in expensive CNC lathes to get the precision finishes they need on detailed components and parts, while others try to accomplish the same precision with older machines at slower speeds. Neither is an ideal solution for larger production runs or rush orders. Fortunately, […]

Types and Advantages of CNC Machines (Computer Numerical Control)

Leave a Comment

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 […]

How Multi-Spindle Screw Machines Work

Leave a Comment

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 […]


An Interview with Davenport’s Lead Design Engineer

Leave a Comment

In the world of manufacturing, cam-driven multi-spindle machines will always be an important part of part production. When it comes to high-volume orders and those less constrained tolerances, cam-driven is the answer. But, as manufactured parts get smaller and technology grows more complex, we are also experiencing an industry-wide demand for tighter tolerances and more […]
