Knuth Machine Tools USA Inc. carries a variety of machines, including high performance bandsaws with automatic feed. The ABS 320C is a fully automated bandsaw with a twin column guide system. The automatic feed system utilizes a powered pinch roller system with ¾ horsepower hydraulic motor for automated, rapid material advancement. Designed with a limit switch to cut lengths accurately, this machine also comes equipped with a programmable part counter for exact productivity and lower material waste, and an automatic height adjustment to limit space between the blade and the material, so no time is wasted cutting air. The saw frame feed has an infinitely variable cutting speed from 65 to 330 feet per minute and a main motor drive rating of 5 horsepower provides for sufficient power reserves. There is also rigid, dual column guide for parallel cuts, a torque-resistant weldment, and a cutting capacity of 13.75 inches by 12.5 inches. The ABS 320C uses new helical gears and a hydraulic cylinder. These gears ensure exceptional quality service, a longer life-span and lower overall maintenance, while the large cylinder dimensions ensure continuous consistent and quiet operation. Plus, the machine incorporates an automatic shut-down when the blade breaks for added safety and productivity. Standard equipment includes a coolant system with 3 nozzles, a saw blade cleaner brush, a 48 inch feed roller table with linear stop, and an operator's manual.
Related Glossary Terms
Machine that utilizes an endless band, normally with serrated teeth, for cutoff or contour sawing. See saw, sawing machine.
Fluid that reduces temperature buildup at the tool/workpiece interface during machining. Normally takes the form of a liquid such as soluble or chemical mixtures (semisynthetic, synthetic) but can be pressurized air or other gas. Because of water’s ability to absorb great quantities of heat, it is widely used as a coolant and vehicle for various cutting compounds, with the water-to-compound ratio varying with the machining task. See cutting fluid; semisynthetic cutting fluid; soluble-oil cutting fluid; synthetic cutting fluid.
- cutting speed
Tangential velocity on the surface of the tool or workpiece at the cutting interface. The formula for cutting speed (sfm) is tool diameter 5 0.26 5 spindle speed (rpm). The formula for feed per tooth (fpt) is table feed (ipm)/number of flutes/spindle speed (rpm). The formula for spindle speed (rpm) is cutting speed (sfm) 5 3.82/tool diameter. The formula for table feed (ipm) is feed per tooth (ftp) 5 number of tool flutes 5 spindle speed (rpm).
Rate of change of position of the tool as a whole, relative to the workpiece while cutting.
Strip or block of precision-ground stock used to elevate a workpiece, while keeping it parallel to the worktable, to prevent cutter/table contact.
- sawing machine ( saw)
sawing machine ( saw)
Machine designed to use a serrated-tooth blade to cut metal or other material. Comes in a wide variety of styles but takes one of four basic forms: hacksaw (a simple, rugged machine that uses a reciprocating motion to part metal or other material); cold or circular saw (powers a circular blade that cuts structural materials); bandsaw (runs an endless band; the two basic types are cutoff and contour band machines, which cut intricate contours and shapes); and abrasive cutoff saw (similar in appearance to the cold saw, but uses an abrasive disc that rotates at high speeds rather than a blade with serrated teeth).
