Products

The Variax VG Series is a coil feeder for presses that delivers high precision and speed.
It can be used for a variety of feeding conditions, such as for feeding irregularly shaped or soft material, in applications that call for micro-pitch feeding and ultra-high-speed feeding.

Wide Product Lineup

Available in a wide range of models and sizes, and designed to meet various feeding conditions.

Ultra-high-speed Feeding

Capable of ultra-high-speed feeding rates of up to 3,600 spm (model VG15H).

Easy to Adjust

Easy dial adjustments of feed pitch, grip force, and material thickness (material thickness is adjustable only on the VG__(T) models).

Handles Various Materials

Inherently designed to feed irregularly shaped material, soft material, and processed material.

Connector
IC lead frame presses
Beverage can presses

*1	A material thickness adjustment dial is furnished on the high-speed type, some general-purpose types (VG___T), and the wide-stock type. For all other general-purpose types, material thickness is adjusted by shims.
*2	Contact Sankyo for material thicknesses of more than 1mm.
*3	The values listed here are Sankyo internal testing standards. Repeatability varies according to actual operating conditions.
*4	Compressed air with a high moisture content can lead to equipment failure. Furnish an air dryer or mist separator to prevent moisture (condensation). Use an air filter with a porosity grade of 5 μm or less. Make sure the air supply is at the specified pressure. Insufficient pressure may cause the release action to fail.
