We offer cut pieces "to finish to" your requirements at no charge when you purchase our materials and strongly suggested taking advantage of these services. The following recommendations are provided should you choose to saw yourself.

BLADE BRAND
A high quality carbide tipped blade, like Lenox Tri-Master or equivalent must be used on all our MoldStar^® alloys. Bi-Metal or non-carbide tipped blades should never be used as they will typically dull immediately.

TOOTH/PlTCH FORM
A blade with a staggered 2-3 or 3-4 teeth per inch works best. Non-staggered pitch blades should not be used and will lead to "work hardening" of the workpiece and the blade will cease cutting and dull quickly.

BLADE SPEED
This style of blade is used for cutting from 1/2" to 3-1/2" thick plates, with band speed at:

150 fpm for 1/2"
120 fpm for 1"
100 fpm for 2"
60 fpm for over 2-1/2"

on a vertical band saw with a hydraulic table feed.
This same style of blade is recommended for horizontal, gravity or hydraulic fed machines as well.

FEED RATE
On hydraulic fed machines, feed rates of:

4" to 6" per minute on thin plates (less than 1/2" thick)
1/2" to 1" plates: feed rates vary from 2" to 4" per minute
plates over 1" thick : feed rates vary from 1/2" to 2 inches per minute

Feed rates are critical in that too light of feed rate will allow the cutting surface to dwell and "work harden" the area to be cut. Common sense and experience provide the best results when it comes to blade speed and feed rates.

COOLANT
Recommended coolant or lubricant is a light mist of soluble oil/air combination. For the ultimate blade life and saw speeds, Accu-Lube, a premium oil is suggested.

WORKPIECE SETUP Always cut MoldStar^® Copper Alloys with the blade in contact with the "thinnest" cross section of material. This means in a horizontal band saw, the plate is verticle or standing, not laying down. On a verticle saw the plate would be laying flat. Make sure that on thinner plates (less than 1 1/2"), the plate is supported adequately as to prevent flexing or bounce.
