The well proven rigid assembly of Eclipse Rectangular Chucks aids accurate grinding or milling. The use of carefully selected pole spacing ensures the maximum possible grip on a wide selection of workpieces. Awkward workpieces can be accommodated by using an additional top plate which can be machined to meet requirements.

|Small Rectangular Chucks - Suited to Toolmakers work|
Eclipse Circular Chucks will hold work during turning operations on lathes and for grinding on internal, cylindrical or rotary grinding machines. They have a rigid assembly, thick top plate and are operated by a removable handle. Eclipse chucks can be partially energised to simplify the correct positioning of the workpiece. Additional top plates can be provided to accommodate awkward shaped workpieces.

Radial Pole Chucks
The Radial Pole range of chucks are highly versatile and are the most powerful of their type. The thru-bore allows easy location for fixturing and for coolant to be fed through the chuck. With the removable brass centre plug in position, the entire surface can be utilised.

Fine Pole Chucks
Fine Pole Chucks have a unique pole design, which in conjunction with powerful magnets, provide an extremely strong and versatile unit, capable of holding a wide range of thinner workpieces. Each chuck in the range has 3 magnetic faces, angled side and end brass stops, smooth, easy switching and variable power.

Workpieces which have an underside projection may require support above the chuck face. Other workpieces may need supporting on an inside or side face. For such applications, chuck blocks should be used to extend the flux paths of a magnetic chuck with parallel poles. They may be used horizontally or vertically, but the laminations must always be placed in line with the inner poles on the chuck top plate. It is permissible to machine chuck blocks to an angle or with grooves to accept irregular shaped workpieces. Supplied in matched and numbered pairs.

Magnetic Vee Block
The Magnetic Vee Block will hold cylindrical workpieces for grinding. It will hold both itself and the workpiece on any flat ferrous surface, including a permanent magnet chuck (without energising the chuck). There are two vees. The smaller model is intended for workpieces up to 20mm in diameter and the larger model is intended for workpieces up to 65mm in diameter. The vees and faces are energised or de-energised simultaneously.
It is sometimes advantageous to use two Magnetic Vee Blocks together (matched pairs are available).
Note: Not suitable for the rotation of workpieces for inspection.

Some workpiece materials retain a certain amount of magnetism after being held by a magnetic chuck. Subsequent operations may necessitate the efficient demagnetisation of the workpiece materials. The Eclipse range of demagnetisers proves invaluable for this purpose. N.B. The Demagnetisers are not intended for continuous use and should not exceed the two minutes 'on' in any four minutes.
The Eclipse Table Top Demagnetiser simply requires a connection to a suitable A.C. power supply. A buzzer indicates when the current is on.
