It’s shaping up to be a challenging year for the forest industry, with the current COVID-19 virus situation affecting all sectors, from the forest to the sawmills—and also restricting what would normally be a busy time of year for many industry people who would be attending and exhibiting at tradeshows, conferences and industry events.
One of the most crucial sectors of the industry, of course, is sawmilling—with the forest industry having been declared an essential industry, sawmills continue to provide customers with much-needed wood products in this very difficult time. Sawmills are still operating, and still needing products, such as saw filing equipment, to turn out those wood products.
In light of the recent cancellation of the B.C. Saw Filers’ Association annual convention, Logging and Sawmilling Journal is pleased to be able to provide our readers with this special “Saw Filers in Print” section.
While some sawmill operations are seeing reduced operations, saw filing remains an essential part of every sawmill operation, and we know it’s important to continue to get information out to the industry. Sawmills continue to need the most up to date technology, and their continued operation is dependent on sourcing saw filing equipment and parts from suppliers.
We certainly know that saw filing-related equipment manufacturers have not stopped developing new products, and we are happy to feature these new products and technologies with these listings.
Since Andritz Iggesund Tools introduced its Powerhead Conical Canter heads in 2003, it has delivered over 600 chipping heads to mills all over North America.
These applications have covered every conceivable species, feed speed and region in Canada and the U.S. Using this experience to further optimize the design of the these chipping heads and TurnKnife System, mills have the absolute best options for canter heads, says the company.
Andritz Iggesund continues to work very closely with the OEMs of canter lines, (BID-Comact, Optimil, Cone-Omega, etc.) to help these companies deliver exactly what a customer demands from a new processing line, or a revamped line.
Andritz Iggesund’s Powerheads have proven to be among the most economical, trouble-free chipping heads available to mills today. The company says the Powerheads are built like tanks, and coupled with the TurnKnife System, give mills the worry-free operations they are looking for in their plants. Most recently, these mills have added Andritz Iggesund canter heads: Dunkley Lumber, Prince George, B.C.; Pine Products, Martinsville, VA; Morgan Lumber, Red Oak, VA; and NorSask in Meadow Lake, SK.
With over 115 installations in North America alone, Key Knife’s Key Planer Head (KPH) product line has a solid track record of increasing production, improving board finish, and reducing operating costs, says the company.
The innovative design and use of the disposable strip knife allows for up to 2X more knives in the same cut diameter of a conventional head. KPH users are able to crank up the feed rate and still achieve a superior finish. The KCC-treated strip knives are proven to last on average three to five times longer than conventional knives, says the company. In addition, the knives are disposable, eliminating all costs associated to grinding and handling larger conventional knives.
FUCHS Lubricants are said to be industry leaders in the development and manufacturing of specialized bandsaw and edger oils, as its saw lubricants are specially formulated for use in bandsaw and edger oil applications. Extensive field testing has been done on the company’s products which allow its customers to reduce oil and water consumption, while minimizing unnecessary saw changes due to heat and guide wear.
FUCHS field technicians have over 25 years of experience and offer free optimizing services and lubrication system audits. The company has worked on and understands most lube systems (both new and old) for bandsaws and edgers.
Industrial Autolube has specialized in only automated lubrication systems for the past 15 years. It has provided solutions to all facets of industry, but specifically the forest industry. Being one of only the few full-line Dropsa Lubrication Systems distributors, it partnered with that company in 2017, and is now part of their global family.
This partnership was brought about when Dropsa saw the technology Industrial Autolube had been developing with its Saw Guide Lubrication System. The system provides full monitoring, and precision control of water and oil dispensing rates, with no air. All parameters are then displayed on a touchscreen in real time. Any alarms pertaining to flow rates or pressure are then displayed for quick, easy troubleshooting. This information has allowed a reduction of as much as 65 per cent in water and oil used by standard systems.
Premier Bandwheel & Equipment Ltd. has a reputation for manufacturing top quality bandwheels at the best possible price for 30 years. The company’s manufactured fabricated bandwheels are capable of a maximum 14,000 SFPM through its mastering specialized welding, machining and dynamic balancing procedures. Headrigs, re-saws or twins in vertical or horizontal configurations, and especially quads, require critical alignment using optical levels and theodolites to ensure all wheels are true to the centerline of the log regardless of if you have a log carriage, line bar, sharp chain or end dogger.
Precision mill set-up including wheel pullback, alignment, cross alignment and sawguide offset can save time and money in every sawmill. Premier’s custom bandwheels can be fabricated or cast for both OEM or direct to the mill end user, with installation assistance available. Many older bandmills or headrigs still use cast iron or ductile iron wheels, and if required or requested, Premier can still produce these styles to original specifications and tolerances using today’s precision casting techniques.
Building on Williams and White’s strong history and reputation for high quality and rugged machinery, the company is proud to introduce the all new Hammerhead 3000 Auto Bench to its growing equipment line.
The Williams and White Hammerhead 3000 Auto Bench is an all-in-one band saw processing center designed to automatically tension and level a band saw with ease. It is a must-have for any sawmill or band saw producer, says the company.
Stand-out features include: an easy saw load system featuring hide-away clamps, independent rigid tension and level heads, intuitive touch screen control with teach functionality, and a full light curtain safety system.
The precision measuring systems for level, tension, and back allow the Hammerhead 3000 to efficiently work the band saw to exacting specifications. The Hammerhead 3000 is currently in stock at the company’s facility in Burnaby, B.C.
The Corbilt Group of Companies includes Wrangler Engineering Ltd. and Corbilt Welding & Fabrication Ltd. who specialize in the design, manufacturing, and installation of various components/equipment for the sawmill and planer mill industry.
The companies’ VDA Outfeed eliminates the need for perimeter guarding due to its 100 per cent contained modular design. The internal design of the outfeed eliminates sawdust spray and flitch hang-ups. The built-in doors allow for easy inspection and maintenance.
Their Wrangler 2 Stage Cyclone was designed to replace filter bag houses. The system reduces downtime and maintenance costs, due to no bags replacement. Wrangler’s vertical rotary air lock eliminates the issues of traditional horizontal rotary airlocks.
Their Bandmill Enclosure captures and controls the sawdust properly while allowing the saw filers and maintenance staff to perform their work easily and effectively. The focus of the enclosures is to capture fugitive dust at its source.
SiCam Systems provides saw filers with the information they need to know on how cutting tools are performing during production. Whether it’s the company’s probe or laser scanning technology, SiCam provides saw filers with critical information to understand how saws are trending over time or to look back at their historical performance.
SiCam’s technology enables a mill to catch issues immediately, notifying the mill in RealTime and providing it with the opportunity to prevent costly saw wrecks from occurring. Log diet plays an important factor on line speed and saw performance; data from SiCam can be used to maximize speed opportunities. Monitor saw deflection and guide ware optimize cutting tool change cycles through analysis that only SiCam’s software provides, says the company. Using all of this information will enable the mill to tune optimization and controls, minimize manufacturing variation, cut closer to/or achieve target size reductions and improve value recovery. SiCam helps mills improve quality and production.
Simonds AutoBench is the proven industry standard for mill run saws, says the company. The 095 uses the same technique and process to measure and recondition saws as do experienced benchmen.
And for mills running headrigs that are substantially thicker than their resaws, the 095 is now available with a Double Tension Roll feature to facilitate quick changeovers for different thickness saw blades. Key features of the 095 include: carbide tensioning rolls, contact sensor, Learn Mode to measure and store the benchwork specifications of a “good” saw blade, and full automatic mode plus manual override options. Simonds has a team of skilled field service technicians and a well stocked inventory of replacement parts. With over 60 units of its latest generation AutoBench in use in North America, the 095 is said to be the industry choice for reconditioning mill run bandsaw blades.
Precision Machinery’s Wireless Saw Temperature Monitoring system provides users with valuable real time information from saws.
Saw temperature data can be used to:
• Identify issues before they lead to catastrophic failures
• Reduce water and oil consumption
• Identify problems in the saw stack
• Optimize feeds and speeds for increased saw performance
A small, wireless, puck-shaped temperature sensor is mounted inside the guide, allowing for accurate saw temperature readings without effecting machine performance. The small profile of the temperature sensor allows the entire temperature sensor to fit within the existing bounds of the saw guide. The data stream is presented live to the operator and is saved for easy data viewing and reference. The system is intended for constant monitoring, allowing the user to integrate temperature data into everyday decisions made during machine operation, with optional PLC integration allowing for automated optimization of machine parameters.
With the advanced technologies that are utilized to process wood products today, the industry is really machining wood, not just cutting it. This is the reason that precision alignment programs are invaluable in wood processing.
The BID Group’s Service Division utilizes advanced Hamar Laser Alignment Systems to maximize accuracy and repeatability to give its customers the highest value service in the industry. With specialized jigs, highly experienced and highly trained alignment technicians, the company provides value and reduced downtime with its alignment services. The BID Group also recommends utilizing its machinery audits prior to the alignment process to maximize machinery efficiency and condition before the alignment process. This will provide valuable information on the condition and the parts required to bring the machine to a level that maximizes the alignment process. Information about BID’s laser alignment systems payback is readily available from the company.
Does your mill have a large number of sorts, or process a lot of cut-n-two products?
USNR has developed and installed unique new sorter designs that accommodate large numbers of cut-n-two sorts while maintaining high production rates. A powerful advantage is that both cut-n-two boards remain in a single lug space.
Options include split diverters that pick out either the lumber-line or clear-line board, or tandem bins that position two short-length sorters side-by-side with independent bin floors under one sorter top.
This sorter solution looks dramatically different, with lumber from the tandem bins and the standard bins discharging to a centre jump rollcase, headed for the stacker.
USNR’s WinTally sorter management system can accommodate all these options, and MyMill mobile control makes it easy to manage the wide variety of products from anywhere in the mill.
Supersaul Chemmex Inc. is in the process of developing and bringing their new saw guide design to market.
The design of these new guides is from a consistent accuracy perspective. Consistent accuracy is maintained by reducing two significant factors: heat build-up in saws and wear to the babbitt on the guides. By utilizing proven technology and applying it to the saw and guides, strict sawing clearances are maintained more accurately.
Also, this design is expected to increase service life of the guide by 50 per cent without consuming more water or lubricant. In other words, sawing accuracy can be increased for a longer duration with the same daily usage in water and lubricant.
In sawmills, efficiency is everything in the drive to cut downtime. The solution is PETROGLIDE ELV, Petro-Canada Lubricants' premium quality emulsified low- viscosity saw guide oil designed for specific applications and tested for multi-blade gang saws and edgers, says the company.
