Title: CB/3 - Single Bevel
Long Description:

Single Head Knives to 8" (200mm) Diameter
Handles knives of all designs including multi edge barrel types
Accurate angle adjustment, positive or negative
Adjustable automatic feed and feed limit
Radial accuracy of the ground blade
Automatic deburr option
Precise grinding angle measurement
High stock removal and good finish
Designed for knives at the smaller and lighter end of the scale

The machine has two motors, one to drive the knife carrier shaft and the second to drive the grinding wheel. The assemblies are mounted on a heavy and substantial cast iron base through which the knife carrier shaft passes carried on self lubricating bearings with grit excluders. The machine will accommodate circular knives of all designs and sizes up to 200mm dia dependant on the rate of required stock removal. This machine is designed essentially for knives at the smaller end of the range. Adjustments are made using quick release clamp levers. Accurate facilities are provided for all grinding angles, positive or negative using clearly graduated scales, and a vertical pillar at the rear of the machine provides adjustment for height and knife diameter. The rotating blade is fed into the grinding wheel automatically at a constant and adjustable rate, controlled by a ratchet and cam arrangement. The ratchet also incorporates a detachable slide which can be preset so that after a pre-determined amount of stock has been removed, feed will be automatically arrested. After locating the blade, the whole operation, which covers grinding, feed and limit, and deburring if requested, is automatic and the inaccuracies and variations of hand grinding are avoided.

Title: CB/7 Range
Long Description:

Autool have a wide range of CB/7 twin head knife grinders. All models come complete on a machine stand with re-circulating coolant system, electric control panel, and a variable speed system for knife rotation which gives a creep feed option for a polished finish. Single bevel knives can still be ground on all of our twin head grinders.

The basic model is the CB/7S which is the most realistically priced and preferred by companies who use circular knives and wish to grind them in house. The other models in the CB/7 range include the CB/7A , CB/7K and CB/7E which have additional equipment on them where a larger volume of knives need to be ground such as... pneumatic tail stock for rapid loading of knives, automatic down feed of grinding heads with automatic spark out timer, knife comparators and more.

The basic model CB/7 can be used to grind circular knives up to 250mm in diameter but this can be changed to suit the needs of different customers.
