Pneumatics Gets Lumber Mills Rolling
In the lumber industry, productivity demands are staggering; output is often measured in lugs per minute, a unit that describes how quickly a machine can process logs and boards. OEMs and timber-processing end users also need machines that can withstand harsh mill problems where temperatures fluctuate, dust damages equipment, and vibrations stress and grate machinery.
Traditionally, heavy-duty steel pneumatic cylinders were the only long-lasting hardware used in lumber production. However, over the past few years, pneumatic solutions combined with lighter and less expensive aluminum have improved sawmill production.
Mills resisted using aluminum because failure of aluminum pneumatic cylinders was common on equipment such as trim saws, where high speed and shock overstressed the units. Even though aluminum cylinders are less expensive than steel, the steep cost of downtime made sawmill operators question their use. “Downtime in a mill is about $1,000 an hour,” says lumber industry consultant Bill Bowlin. “So if a trimmer stops for some reason, the whole mill stops because all the boards have to pass through the trimmer to get out of the mill.”
Now, a new combination of pneumatics, aluminum, and ideal cushioning increases cylinder longevity and performance. The latter is a solution developed by Bosch Rexroth Corp., Lexington, Ky., that gently decelerates the pneumatic piston as it reaches end of stroke inside the cylinder to eliminate bounce and end-cap slamming, two main culprits of cylinder wear.
It is particularly useful for eliminating excess piston movement and bounce on quickly cycling, highly kinetic sawmills, especially in trim saws where pneumatic cylinders constantly drive blades up and down. Piston velocity — at its maximum speed throughout the stroke sequence — is exactly zero when it reaches the end cap. Vibration and noise are reduced and cycle time is improved, boosting machine speed as much as 30%. Cylinders with ideal cushioning are also lighter to further improve acceleration and cycle times.
Advanced Sawmill Machinery Equipment Inc. (ASM), Holt, Fla., worked with Bosch Rexroth to incorporate aluminum cylinders with ideal cushioning in its Series 140 Trimmer. The machine builder wanted to offer faster cycle rates and more durability.
ASM president David Seffens says the cylinders make their high-speed trimmer competitive and play a big role in opening up the 140 to 200 lugs-per-minute market for ASM. Seffens also notes that all the saw ladder surfaces on the Series 140 Trimmers are machined, keyed, and require no alignment by the customer. With the aluminum cylinders, each machine is customized for speed at the request of the end user.

The 2006-2011 World Outlook for Manufacturing Hydraulic and Pneumatic Fluid Power Cylinders and Actuators $795 The latent demand for manufacturing hydraulic and pneumatic fluid power cylinders and actuators is not actual or historic sales. Nor is latent demand future sales. In fact, latent demand can be lower either lower or higher than actual sales if a market is inefficient (i.e., not representative of relatively competitive levels). Inefficiencies arise from a number of factors, including the lack of international openness, cultural barriers to consumption, regulations, and cartel-like behavior on the part of firms. In general, however, latent demand is typically larger than actual sales in a country market. |

Pneumatic Lubricator $68.51 High Quality Content by WIKIPEDIA articles The pneumatic lubricator is a device which injects an aerosolized stream of oil into the airline. This is used to provide lubrication for internal working parts of pneumatic tools and components such as actuating cylinders, valves and motors. Pneumatics is that branch of technology, which deals with the study and application of use of pressurized gas to affect mechanical motion. Pneumatic power is used in industry, where factory machines are commonly plumbed for compressed air; other compressed inert gases can also be used. Pneumatics also has applications in dentistry, construction, mining, and other areas. A compressed fluid (also called a subcooled fluid) is a fluid under thermodynamic conditions that force it to be a steam. In a plot comparing absolute pressure and specific volume (commonly called a Pv diagram), of a real gas, a compressed fluid is to the left of the liquidvapor phase boundary; that is, it will be to the left of the vapor dome.

The World Market for Linear Acting Pneumatic Power Engines, Motors, and Cylinders $325 This report was created for strategic planners, international executives and import/export managers who are concerned with the market for copper springs. With the globalization of this market, managers can no longer be contented with a local view. Nor can managers be contented with out-of-date statistics that appear several years after the fact. I have developed a methodology, based on macroeconomic and trade models, to estimate the market for copper springs for those countries serving the world market via exports or supplying from various countries via imports. I do so for the current year based on a variety of key historical indicators and econometric models. |

The 2006-2011 World Outlook for Non-Aerospace-Type Linear Pneumatic Fluid Power Cylinders with Less Than 1-1/2 Inch Bore Size Excluding Rodless, Aluminum, $795 The latent demand for non-aerospace-type linear pneumatic fluid power cylinders with less than 1-1/2 inch bore size excluding rodless, aluminum, and steel types is not actual or historic sales. Nor is latent demand future sales. In fact, latent demand can be lower either lower or higher than actual sales if a market is inefficient (i.e., not representative of relatively competitive levels).
