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.

CJWinter offers Quick Change Tooling (QCT), taking change-over of sideworking and endworking tools on the Davenport from hours to minutes. The QCT package eliminates time-consuming adjustments and changing of tools, according to the company. The QCT stationary and revolving spindles are said to make it easier to change endworking tools for a Davenport machine.

When your only product is socket set screws and your primary customers are the demanding aerospace and military markets, quality and uptime are paramount. Your multi-spindle machines need to be reliable and easily reconfigured to produce a new part at a moment’s notice.

The company's Model 190 end rolling attachment is described in this color literature. Measurements and optional components are also listed and pictures illustrate the attachment. .

The company has introduced an end-rolling attachment for thread rolling applications on CNC turning centers, Swiss, multi-spindle machines and others. The Model 190 features a single-piece front-plate design that provides high rigidity for long tool life and better quality threads, the company says. The single-piece design is said to provide thread roll protection.

The new NC41 Series Tangential Thread Rolling Attachment is said to provide reliable service with a high degree of versatility and ease of use unmatched in the CNC thread rolling industry. Compact yet able to handle a wide range of sizes, this head incorporates several attachment features. The pitch diameter knob is said to allow easy adjustment without tools.

Hakusui USA has introduced Mist-R-Cool, a stand alone cooling system with ECOREG technology that can be adapted to existing machine tools to provide the similar cooling and lubrication performance. Mist-R-Cool is available in models to serve a single machine or two machines at one time. The patented ECOREG system blends water plus very small amounts of coolant and lubricant which is dispensed at extremely high pressure in the form of a super particulate mist stream.

Virtually all precision machined part manufacturers require a method of cleaning their parts prior to shipment to their customers. And because many machine shops cut with oil, parts cleaning is usually a complicated multi-step process.

The tangential thread rolling attachments feature an easy-to-use pitch diameter adjustment that can be used without any tools. The 360-degree compensator makes it easy to synchronize thread rolls without the need to remove the attachment from the machine. This compact attachment can handle a wide range of thread ran

TurretJet Universal Coolant Nozzles are now rated for operating pressures up to 150 psi (originally 40 psi). This allows them to be used in many machine tools having high pressure coolant pumps. TurretJets fit both NPT and BSPT threads, are rugged, compact, quick and easy to aim, and are difficult to accidentally k

Few screw machine shops can escape the inevitability of tighter tolerance demands from customers. Getting the most accurate tool travel from a screw machine is a key component to consistent part production.

The company will display the new 132 EG Series Reversible Slide that lets a Davenport act like a six-spindle machine. This slide fits both first and second positions and incorporates a precision-fit dovetail expansion gib. Its precision and rigidity virtually eliminates chatter while making deeper and wider cuts in
