Introduction To Diamond Saws
Ref: IntroSaws

These units are all designed specifically for sawing and would normally be used in conjunction with a lapping or grinding machine.

A Diamond saw-blade consists of microscopic diamond particles embedded in the rim of a thin metal disc. Unlike a saw for wood or metal, a Diamond blade does not have 'teeth' and it has a fine grinding action rather than a cutting action. Because of its construction, it is possible - to most peoples surprise - to hold a finger against the rim whilst the blade is running and the flesh will be cleaned but not cut !

Quite a lot of heat is generated during the sawing process and for this reason a coolant has to be applied at the point of cut to prevent blade damage and stone cracking. Water is adequate as a coolant on saws of 6" diameter or less but this would evaporate too easily on a deeper cut so larger blades are used with a special coolant ('MetPrep Cool') as shown below.

Ameritool 4/5inch Saw (220v) with 4inch Blade & Vice

Ref: 13-010

Suitable for trimming glass, cabochon pre-forms and facet rough. The large (11cms x 21cms) table has no inhibiting lip so is capable of trimming oversize slabs and rods.
The body of the machine is made from durable polyethylene and the table top moulding lifts off for ease of cleaning.
The variable speed direct drive (110v 1/4H.P.) is operated through a plug-in auto-transformer (220v) and will run fast enough for ultra thin blades but powerful enough for sintered diamond blades up to 5inch diameter (5/8 inch arbor).
The included aluminium and stainless steel vice (which can be swung out of use) is ideal when trimming or slicing precious facet material or glass rods or cubes.
The supplied 4 inch blade is a low-cost unidirectional notched rim thin (0.002) blade suitable only for softer materials such as turquoise, lapis and opal.

These units are all designed specifically for sawing and would normally be used in conjunction with a lapping or grinding machine.

Quite a lot of heat is generated during the sawing process and for this reason a coolant has to be applied at the point of cut to prevent blade damage and stone cracking. Water is adequate as a coolant on saws of 6" diameter or less but this would evaporate too easily on a deeper cut so larger blades are used with an oil.This unit is motorised and supplied complete with a 4" notched thin rim diamond blade making it ideal for Opal or other precious gemstone fine cutting work.
This unit ref 13-001 is not a general purpose trim saw and will not cut Geodes etc., but is ideal for the purpose for which it is designed - i.e. as a faceters trim saw.
