Rectangular Chucks
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.

Circular Chucks
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.
| Catalogue No. | Outside A (mm) | Thru' Bore | Pole Depth C (min) | Height d (mm) | No of Poles D (mm) |

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.

Chuck Blocks
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.

Demagnetisers
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.
Table Top
Demagnetiser
The Eclipse Table Top Demagnetiser simply requires a connection
to a suitable A.C. power supply. A buzzer indicates when the
current is on.

Magnetic Vice
An accurate grinding vice which can be used on its base, side
or end. As it is not necessary to disturb the workpiece between
these attitudes, the achievement of 3 dimensional squareness
is assured. The hold is entirely magnetic and the vice is not
subject to the distortional thrust of a screw. The faces are
ground to the following deviations: Parallelism - 0.005mm, and
Squareness: 0.01mm per 100mm.
