The newly engineered Varimec lead-screw selfeeder was designed to meet the demand by manufacturers for a smaller, more powerful and accurate self-contained drill unit capable of a high degree of accuracy in a range of metals and other materials, according to the company.

Available in two electrically-driven models, the SSV3 is rated at 0.5 hp (0.4 Kw), while the larger SSV5 unit is rated at 3.25 hp (2.5 Kw).

Spindle runout for both units is under 0.0004" TIR.

Internal linear slides used to guide the quill are among the engineering features incorporated into the units that have increased the rigidity and reduced their sizes. Designing the spindle motor within the moving Z-axis quill and other features have reduced the overall size of the SSV3 to 22.3" (567 mm) and the SSVS to 34.3" (871 mm).

The extremely high rigidity of the machines eliminate side-load chattering, enhancing their versatility to perform end milling and face machining operations, the company says.

Nominal unit weight for the SSV3 is 94.6 Ibs (43 kg) while the nominal weight of the SSV5 is 220 Ibs (100 kg).

Programming is accomplished with an available hand-held programming console to input information or through the R232C port for use with a laptop computer.

The controller can store up to 99 individual programs. There are 13 preprogrammed drill modes including standard, step, dwell, skip, spot face, inverse spot face and other drilling modes to simplify setup and production.

The unit is furnished with a feed controller, an inverter for spindle speed operation, all interfacing cables and hardware that are necessary for easy integration into any manufacturing operation, cell, system or dedicated machinery. The units can be mounted directly to a machine base or to adjusted columns to provide accurate drilling or machining at any required angle.

The selfeeder can be equipped with multi-spindle drill heads and offset drill heads to increase their productivity and versatility.
