Servo Feeds

EF Series

EF Series feeds are designed to provide an economical means of employing servo feed technology to smaller presses without sacrificing build quality, accuracy, durability or power.

The EF Series is known for holding very accurate tolerances. The reason for this is their unique direct drive setup. This direct-coupled arrangement places the motor's encoder in-line with the roller, providing precise feed length accuracy.

The mechanical design of the EF Series also sets it apart. Consider all that is standard on every model: solid, matte finished rolls, air cylinder roll pressure and pilot release, planetary inline reducer, cluster gear power transfer and pivoting upper roll assembly for ideal gear mesh.

The EF series can be equipped with a pull-thru straightener to reduce space and capital investment in the overall feed line. See this link for more information.

Another significant difference between EF Series feeds and other models is power. Compared to similar competitive brands, some EF Series feeds may have 400% to 800% more torque!!

RF Series

The RF Series feeds are ideal for many medium to heavy duty stamping and cut-to-length applications. This series comes in 5 sizes, ranging from 4” to 8” diameter feed rolls in an array of coil widths. High torque servo motors drive either orbital or helical-bevel reducers make the RF series both powerful and precise.

feedlease RF servo feedThe exceptional mechanical design of the RF Series sets it apart from many other feed designs. Vertical tie-bars provide amazing structural rigidity. Spherical roller bearings support the feed rolls across the entire rated width of the feeder. The feed rolls come standard with matte finish for maximum gripping power.

RF Series feeds can be equipped with a pull-thru straightener to reduce space and capital investment in the overall feed line. See this link for more information.


feedlease RF servo feedThe roll pressure is applied by two adjustable stroke pneumatic cylinders. Roll pressure is adjusted by a supplied regulator. The same cylinders are also used for the pilot release of the upper feed roll. These cylinders are positioned well past the center point of the rolls to provide maximum power to the roll. The rolls lift and lower on a pivot, rather than up and down in a slide block, to ensure full gear mesh regardless of the thickness of the material. Many other standard features are included (see box below) that make the RF Series one of the best values of any servo feed in its class.

Controls

Feed Lease Corporation is proud to employ top quality controls on every servo feed. Each Feed Lease servo feed utilizes a Control Techniques drive for superior performance. Since no components of the electronic system are proprietary, you have the option to use your local distributor for any replacement parts.

Servo Feed ControlsAll feeds except EF) are PLC-based, allowing a wide array of functionality including four different jog modes, part recipe storage, and an integrated batch count. The standard control includes a feed complete output (optional on EF series) to use with simple press signal-feed/feed-signal press and cut-to-length applications.

Optional I/O are available for more advanced cut-to-length systems. Our optional Automated Line Solution allows any powered axis to be stored in the job recipe storage and automatically position when a given job is loaded. The optional Off-Site Remote Service adds to our 24/7 service commitment by allowing our controls service personnel access to the feed line controls remotely. We can take control of the feed line for troubleshooting and setup adjustment from anywhere in the world at a moment's notice, anywhere in the world!
