SANKYO Variax VG-Series Cam Driven Grip Feeds for Smooth "High-Speed" Operations

SANKYO's Variax VG-Series feeds with a Roller Gear type Feed Angle Cam and SANKYO's Special Sine Curve, provides controlled preprogrammed acceleration and deceleration for a smooth adjustable feed motion. SANKYO's cam controlled adjustable stock grip and brake pressures, allows for high-speed operation with less chance of marking soft material such as copper, aluminum and soft brass, etc.…. than any other type of feeder on the market. Cam controlled pilot release allows precise opening and closing of the brake jaw for better control of stock at high-speeds.

Feeding delicate and thin material at high-speeds is made possible when using the SANKYO VG-Series feeds.

SANKYO VG-Series grip and brake jaws are specially designed for feeding different types of stock such as flat material from the very soft to the very hard as well as different types of preformed material. Different configurations can be designed into the jaws to conform to the shapes of the material being feed. SANKYO also has jaws for feeding single or multi square or round wire for different applications. The Grip and Brake Jaws can be changed very quickly for different types of jobs.

Features

· Upper and Lower jaws are driven for better gripping of material at lower pressures.
· Roller Gear type feed angle cam with SANKYO specially designed sine motion with controlled acceleration and declaration for smooth feed motion.
· Job change over can be made more quickly than most other feeds in its class.
· Adjustable feed pitch can be made without changing cams or gears.
· Adjustable grip force on material.
· Replaceable grip jaws.
· Grip jaws can be changed very quickly.

Options

· "High-Speed" kits for most models.
· Micro-Adjustment for grip and brake jaws eliminating jaw shims for different material thickness'.
· Different types of stock guides.
· Extended stock guide plate and guides from feed to edge of press bolster plate.
· Inlet stock catenaries.
· Extra grip and brake jaws with many different types of gripping surfaces and configurations.
· Guides for wire applications.
· Stock clamp for either flat stock or multi-wire.
· SANKYO Mechanical Self-Compensation Tensioner (S.C.T.) feed drive.
· SANKYO Servo-Driven (VSD) feed drive.
