HEM Saw H130 Bandsaw Machines
Gerald R. Harris founded HE & M, Inc. (HEM) in 1964. For fifty years, HEM Saw has maintained its reputation as the manufacturer of quality and durable bandsaw machines. HEM Saw remains a leader in the bandsaw industry, consistently setting the standard with more patented innovations than any other bandsaw manufacturer in the world. HEM manufactures more than 70 different models of production bandsaw. One of their most successful achievements is the H130 Series bandsaw machine. The cutting capacity for this series ranges from 16” x 16” W to 10” x 20” W when cutting shapes. All three use a 10hp motor with 2hp hydraulics. …
Double-Weld Bandsaw Blades
Depending on the needs of our customers, Sawblade.com offers welded-to-length bandsaw blades. This process involves cutting the blade to length, welding it, and then annealing the blade. There are rare instances when a bandsaw blade will have two welds instead of just one. If an order for 16’ of bandsaw blade arrives, and the weld shop only has 10’ of band in stock, the manager may feel confident about permitting an employee to take the 10’ band and weld 6’ more provided it is from the same stock. The weld shop may weigh the potential for problems versus waste and loss. The customer has the right to refuse the …
Bandsaw Blade Tooth Set
The bending out of the blade’s teeth, left or right, and away from the blade is known as tooth set. It works to give a straighter cut. Tooth set clears the chips from the kerf, allowing the band back to clear the cut without binding or becoming stuck in the material. The set will vary depending on the intended cut. A rip saw has a tooth set similar to the angle used on a chisel, ripping the material apart. A flush-cut saw has no set on one side, allowing the saw to be laid out flat onto a surface and cut without scratching. The set of a blade’s teeth …
Gullet Cracks
There is no substitute for a well designed, properly maintained, and fully functioning bandsaw machine. When things go wrong, it is usually due to maintenance having been avoided for any length of time. Avoiding gullet cracks is part of an ideal maintenance procedure. The gullet is the second hardest working bandsaw feature. A properly cleaned gullet is critical to achieving correct cut, appropriate band cooling and lubrication, and for adequate chip removal to occur. Gullet cracking stems from a number of variables, but the likely cause is the machine and not the blade. Band straightness, too tight blade guides, too high blade tension, too heavy a …
Variable Speed Pulley
A variable speed bandsaw machine has several speed drive systems located within the base of the machine. It consists of two v-pulleys mounted on a common bearing tube. A belt on one pulley is driven by the transmission while the belt on the other pulley drives the saw band drive wheel. Two outside pulley cones are fixed, but the middle cone shifts when the speed change wheel is turned. These two v-pulleys play a significant role in controlling the machine’s blade speed and help provide accurate cuts. The main advantage of variable speed pulley is its being economical. It allows for various …
EHS IC-Heavy Set Bandsaw Blade
Extra Heavy Set bandsaw blades are equipped with heavy-set teeth that provide extra blade clearance. This minimizes binding or pinching when beam stresses are relieved and/or when bundles move during cutting. Because of its tooth geometry, EHS blades reduce vibration and noise levels, providing for smoother finish and the prevention of chipped and stripped teeth. EHS are the types of blades preferred in structural cutting applications and are specially designed for cutting H- and I-beams and structural steels that have a tendency to close in on a cut. They are also excellent for use by steel fabricators, production cutting houses, and …
C-3000 Full Synthetic Cutting Fluid
Coolant fluid is designed specifically for metal cutting applications and machining processes. It is made to cool the material being cut and lubricate the blade doing the cutting. The oil used provides a measure of corrosion protection and helps remove metal shavings (chips). The two types of coolant or sawing fluid are synthetic and semi-synthetic. Both are translucent blue, water soluble, and designed as moderate to heavy-duty sawing fluid. Full synthetic is used in all sawing and grinding procedures while semi-synthetic is created exclusively for sawing applications alone. At SawBlade.com, we offer both varieties of coolant in C-2000 semi-synthetic and C-3000 full synthetic coolant. C-3000 …
Clamps/Vices
Bandsaw machines are as common in woodworking shops as they are in the metal cutting industry. They are also one of the most powerful and extremely useful tools in both industries. In either case, the machines consist of various and unique parts. Understanding them all and applying proper maintenance is essential to safe and productive output. Two of the most essential parts of a bandsaw are the clamps and vices. A vise is used to hold the material in a solid, fixed position and it usually consists of two jaws that open and close via screw or lever. The jaws are separate pieces made of …
