Rockwell Hardness Scale

Hardness is a materials characteristic and not a fundamental physical property. Knowing the hardness of any metal or alloy is important since hardness value is in correlation to other properties such as materials size and thickness. The Rockwell hardness test is a measurement based on the net increase in depth of impression as a load is applied. Hardness numbers have no units and are commonly given in the R, L, M, E, and K scales. The higher the number in each of the scales means the harder the material. The Rockwell hardness test worldwide adoption likely resulted from the test …

Haltbar M42 701-601 Series

The Haltbar M42 701 series bandsaw blade will cut through applications that the 601 series blade cannot. The 701 series is designed to cut Inconel, D2, Monel, and other exotic alloys. The unique tooth geometry, plus the addition of an 8% cobalt backing strip, helps to assure prolonged blade life even under constant feed pressure. The 701 series bandsaw blade is good for production cutting of stock bars and solid rounds, and is recommended for applications that are prone to work hardening. The 701 series variable tooth height and set make this a high performance bandsaw blade that allows for an …

Machining Alloys

Machining alloys is what most metal cutting industry shops do. Fabrication, drilling, cutting, milling, bending, and punching operations will all end up encountering problems in the process of machining alloys. Rough finish, bending of materials, poor product texture, and machine aspects like wear, tear, and blade dulling or breakage. These issues cause slow production output and incur unwanted cost — to both materials and equipment. Aluminum alloys are a commonly used lightweight metallic materials that are easy to shape. Aluminium alloys are material that offers high machine ability as opposed to titanium or magnesium. Factors to consider when machining alloys include tool life, chip removal, removal rate, …

How to Determine Bandsaw Blade Size

When trying to figure out how to determine bandsaw blade size, it is important to know the job that will be performed using that particular saw blade. Things like material, amount, and cut. To help determine the proper bandsaw blade size for a particular machine, follow this formula: For two-wheel bandsaws Adjust the wheels to their correct position (about the middle of the adjustment range) make sure the wheels are not adjusted to the extreme Allow for take-up to tension the band and for possible future blade re-welding. The middle of the adjustment range is best Band length = (R1 x …

Metallurgy and Bandsaw Blades

The study of metallurgy and its impact on bandsaw blades is invaluable knowledge for any machine or woodworking shop employee and key to proper application in any cutting process. To better understand the need-of-use for the different types of saw blades and their effect on different types of materials, a better understanding of the terminology and application becomes more clear. Metallurgy is the study of physical and chemical behavior of metallic elements, their inter-metallic compounds, and their mixtures, which are called alloys. Another way of describing it is the way in which science is applied to the production of metals and the engineering of metal …
