Taranakipine Saw Shop Upgrade Project
The Taranakipine saw shop upgrade project all started with a conversation about a saw trial on site of the Thode designed Variable Pitch & Depth profile with the dream of the projected gains in productivity paying for a state-of-the-art re-fit.
The Thode VPD profile differs from the more traditional ascending and descending patterns that had been more commonly used over the years, by using an alternate layout of the pitching to create a wave looking profile further enhancing the effects of the VPD concept.
Working with Taranakipine’s saw shop contractor, Craig Robinson of Fred Robinson Saw Doctors and sawmill manager Rodney Baker, the trial got the go ahead and two saws were ordered “ready to run” meanwhile Craig and Rodney set about gathering as much information as they could to form solid base line data of where the sawmill was currently performing.
In mid-September 2021, the Thode VPD saws arrived on site and the trial was underway.
There was noticeable difference in performance instantly and at the end of the trial with all the data collected the improvement in sawmill performance was significant!
This information along with a list of the top-of-the-line Iseli machinery for a full saw shop fit out was then presented to John Sanders, Taranakipine’s Plant and Projects manager so the numbers could be crunched for justification.
The capex put together by John and his team flew through board approval and the order for the Iseli machinery was placed.
Meanwhile we set to work planning the new saw shop layout. We used 3D models of the Iseli machinery to generate several floor plans for different layout options, and through consulting with Craig we found the perfect layout to maximize space and flow through the saw shop for what he and the team needed for ease of day-to-day operation.
The team had a goal of “zero” sawmill down time for this project and to accomplish this we had to have a bullet proof installation plan, the timing and order of existing gear to be removed and the order that the new gear would be positioned and powered up would have to be perfection.
Working with Craig and the Taranakipine maintenance team we crafted just that, removing as much of the old gear to give the floor reconditioners and painters as much time and space as possible before the new Iseli equipment arrived on site.
In November 2023 five pieces of Iseli equipment arrived on site, this consisted of one RZ1 auto benching station, an SAA Stellite tipper, a BNF100 5 axis CNC side grinder and two BNP110 2 axis CNC profile grinders.
The plan worked like clockwork, perfectly staged to maximize time for all trades involved.
Week one, the SAA, BNF and both BNP grinders were installed, power on and sharpening saws.
Week two, the last of the old gear removed and the RZ1 installed, tuned and training on all machinery commenced.
While this was a big task the “zero” mill down time goal was achieved with the sawmill never missing a beat! Something that everyone involved can be extremely proud of!
At the start of week two, now with both BNP110’s up and running the new Thode VPD saws were unleashed on the mill and very quickly the gains become apparent! So much so that we had barely started the week and the operators no longer wanted the old standard pitch saws and Rodney made the call that they were to no longer to be used!
“We got everything up and running in the first week of November 2023. From that point on we noticed the difference in cutting speeds, sawing accuracy improvement, cleaner cutting no feather edges, less reprocessing due to accuracy of cutting, less intermittent saw changes, quieter cutting, motivation of saw doctors and production crews around upgrade of saw shop having new gear and technology in the saw shop. With wet grinders it made a huge difference to the air quality and the housekeeping was made easier as well with everything being contained. Overall, we are well on track to hit our targets for the payback time of this install. Thanks to all parties involved.” Rodney Baker- Sawmill Manager.
BEFORE & AFTER
A night & day difference, not only in presentation but in performance too!!
After a few months of running and the sawmill operation staff having the time to settle in, it has become clear that there have been gains in several areas as Rodney has mentioned above.
It is important to note that the only thing changed in the sawmill at this time was going from a standard pitch profile to the Thode VPD profile on all band saws.
The trial was a great success, testing in a controlled environment, removing as many variables as possible with the data recorded clearly showing that if you want a way to pay for your brand-new saw shop this is the way to accomplish it!
Thode 100% recommend and stand behind the Thode VPD profile as the best option for sawmills to maximize productivity and drastically reduce their manufacturing cost / M3 making their business more profitable.
We would like to take this opportunity to thank the team at Taranakipine for putting their trust in Thode to deliver another successful Iseli installation.
The new Saw Shop is light and bright with the new layout spacious and user friendly.
"All I can say is that the accuracy is Awesome! And the Iseli gear is very easy to
use” - Craig Robinson

A Positive Move For Thode Knife & Saw Ltd Christchurch.
As of 1st July 2023 Thode Knife & Saw Christchurch started the move to a new building better suited to our current size and customer base. The previous building had been fit for purpose for 25+ years and as the industry changed, the need for such a big building didn’t fit our needs going forward.
We are now situated at 29A Blakes Road, Belfast in a new building that we had some input into the design and layout of the office / store and staff amenities and are now firmly placed to service our customers from this site. Our staff are over the moon to have a new building and bright and airy working conditions. “The move gave us the ability to create a much better, more efficient factory layout and introduce new machinery in a controlled well-planned manner.
During the planning stage of the move we decided to upgrade an area of our factory to meet the current needs of our customer base, namely our Tungsten Carbide (TCT) circular saw servicing area. The TCT area now has a fully automated circular saw grinder that is fitted with a self-loading arm. This machine has replaced two Vollmer CX100’s and increased our ability to service our customers saws 50% faster and saws serviced to date are showing a great level of both accuracy and sharpness. The robotic combination means when we have high levels of saws for servicing we can stack and load the trolleys and set the machine to run overnight so when we arrive in the morning all saws are sharp and ready to go back to the customers.

Aaron would like to thank Neil Hunter, Robert Dunn and the Team in the Sawshop.
Recent Machine Upgrade at Pan Pac Otago
As part of a continuous improvement programme, Pan Pac Otago recently installed an Iseli KHF100 circular saw side grinder into the Milburn site sawshop. The KHF100 replaced an older North American machine that had worked well on site for many years but had reached its end of serviceable life.
Both Pan Pac’s sites have an array of Iseli equipment already, so the decision was made to replace the existing side grinder with an Iseli KHF100 Fully automatic 6 axis CNC machine. The KHF100 is designed for fully automatic grinding of the side angles on Carbide/Stellite tipped circular saws, and features space saving machine design that allows for high ergonomics and excellent usability, as well as ease of access to the electrical cabinet, coolant pump, pneumatics and fire suppression system.
Other notable features are:
- automatic adjustment of all common angles
- automatic detection of the tooth pitch with built in sensor technology on the feed finger
- the ability for the positioned tooth to be finished in several passes (saw finish ground in one rotation)
- high flow capacity oil coolant
- automatic CO2 fire detection and supression system.
The machine is controlled via a 15.1 inch colour touch screen with Windows-based interface for fast saw parameter loading and has unlimited program storage.
The grinder was installed in November 2023 and commisioning and training was completed by Regan Eisenhut from Thode Knife & Saw Rotorua.
Thode Knife & Saw would like thank the team at Pan Pac Otago for choosing the Iseli machine and the help given to Regan while commisioning and training.

Centrifugal Mobile Cleaning Station
Thode Knife & Saw Auckland recently purchased a mobile cleaning station marketed by Iseli.
The centrifugal system gives superior cleaning of oil coolant over their older filter system which was fitted to their manufacturing centre.
When the machine was first connected to the top and face grinder the coolant was at a stage that it was due for a full change. After running the centrifuge for a week, the coolant was back to its near original colour.
They now rotate the RUMA on all their machines.
Darren Clissold, Auckland Production Manager, is thrilled with both the efficiency of the cleaner and the massive cost savings from not having to replace the specialized grinding oils they run in their machines.
He also enjoys the ease of set-up and the lock out switch which means the machine complies with H&S requirements.
Thode Canada and OFO Australia are also thrilled with the operation of their RUMA cleaning units
Contact your THODE REP to find out more about these machines.

Variable Pitch and Depth Bandsaws
Variable Pitch and Depth Bandsaws
By: John Eisenhut
A bit of background on myself, I’ve been in the Saw doctoring industry for quite a few decades now and in those years I’ve experimented a little outside the box with many things over those years.
Several in particular:
- Hit and miss tipping
- Variable kerf, something I have a huge passion for.
- Variable pitch band saws off older cam Technology grinders.
Now most of us know and I would think agree that reducing vibration in a saw is beneficial.
A Variable Pitch or Variable Pitch and Depth saw will run quieter than a standard pitch profile. There is no doubt about this; it’s an actual fact and has been documented well over the years.
So a few points to consider
Firstly: from a health and safety point of view, quieter saws in the saw mill are an immediate benefit in itself, and for most in the industry reason enough to make the change to a Variable Pitch saw.
It is common to receive feed back from the operators that they can’t hear the saw and in the next breath say I don’t like it, I can’t here it how can I cut fast and smooth if I can’t hear it?
What he is actually saying is the saw has changed its cutting pitch.
This is nothing that a re-adjustment period and a bit of reassurance and coaching over a few days won’t fix and it is definitely not something that should dictate not changing to the Variable Pitch concept.
This is a free advantage, no outlay, no more expensive than a standard saw.
Old technology grinders or standard cam grinders can grind a three pitch scenario with not too much effort, so the gain is there for us all.
Another benefit from a VP saw is the ability of the saw to decrease or eliminate completely any wash board that may be occurring… This. again is achieved without any other investment or modification being required. It’s a free fix.
Some of the myths around using Variable Pitch saws are that they cannot be serviced on a cam driven grinder, this is absolutely not the case.
Yes care needs to be taken to not over grind the face of the tooth “and” the tooth shape may not be as “pretty” as a CNC machine, however the additional benefits are there to grab. Your choice
The assumption that a VP saw is harder to deal with is also misguided information, setting a Variable Pitch saw going on a cam grinder or a CNC grinder is a simple task.
Continued Benefits
Now the money maker advantages
Increased feed rates
A decrease in within board deviation or a combination of both and again these benefits are being harnessed without any other investment or upgrade, it’s effectively a free performance increase for your sawmill.
You have to buy saws for your saw mill; there is no difference in price between buying a standard profile saw or a Variable Pitch profile saw,
We at Thode can cut your saw to any profile you require
Water cut by Thode Knife and Saw / cold cut flat and true, with no punch deformation
Even if you only have a cam driven grinders we can cut a profile to suit what they produce,
Our CNC water cutter allows us to cold cut your profile to very close tolerances,
The cut is clean, accurate and without heat absolutely no deformation in the plate
This can save you hours of grinding time, and have your new saw up and running in no time at all.
Massive leap in technology for Bandsaw Shop" self programming & self setting bandsaw profile grinder (Iseli BNP200)
Iseli Latest Technology
ISELI TOOTH TRACING SYSTEM (TTS)
Programming tooth shapes is still a major challenge for many customers. The ISELI Tooth Tracing System (TTS) can help! The tooth shape of the saw you desire to be emulated can be probed automatically by an acoustic sensor and saved as the tooth shape of your choice. The data obtained is then used for sharpening in the recipe. Parameters such as tooth profile, hook and back angles, tooth height, variable pitch and depths etc, are automatically determined and saved by the program.
This process enables the exact reproduction of existing tooth shapes directly on the machine without a great effort. These can be used going forward on all saws you have in service. So an exact repeat of tooth profiles on every saws
Inaccuracies are also copied, which means that the removal and thus the costs can be reduced to a minimum, even if the profile is not precisely defined. In addition, inaccuracies on the grinding wheel are compensated for when probing and enables absolutely precise grinding of the profile, even with a worn grinding wheel.
Tooth shapes generated on a system using TTS can be read in other ISELI machines of the BNP series.
AUTOMATIC INSERTION AND EXTRACTION
Automatic insertion of the blade is now possible. The machine inserts the blade until a height pre-set in the recipe has been reached; the machine then closes the saw clamp. The first saw tooth is determined and the tooth pitch is calculated. In the case of variable tooth shapes, the group of teeth is automatically detected. This significantly reduces operating errors and the effort involved in searching for variable divisions.
The saw blade can be inserted / lifted to the stop point automatically on demand in automatic mode. The search for teeth and the determination of the zero point takes place automatically and the grinding process is started. In summary, the operator can insert the blade and start the machine by pushing the start button. The rest of the work is done automatically by the machine. The option is completed with a revised height adjustment, which works faster and more precisely thanks to a variable-speed drive.
Pan Pac Napier Invests in High Tech Iseli Saw-Shop Machinery
The Iseli BNP200 Bandsaw Profile Grinder
The BNP 200 automatic profile grinders are equipped with a 3 axes CNC system which gives automatic tooth finding functionality and different options for optimised accurate profile grinding. This also opens the door to many other saw machining options for the future.
A user friendly touch screen makes the machine very easy to use.
Pan Pac have opted to run a full oil immersed CBN wheel system. The Iseli machines were found to have the best oil containment details of all machines considered including close fitting wipers, oil mist extraction system and a fully automatic fire suppression system.
The machines run an electronically controlled central height adjustment system for saw blades, a pneumatic blade clamping system. The machine also has a Thode designed swarf magnet and back feed engagement device, both of which build upon the base machine from Iseli.
The Iseli BNF100 Bandsaw Side-Grinder
The BNF side grinder from Iseli is a 4 axes CNC machine; it runs a user friendly touch screen that makes the machine very easy to use.
The machine runs a full oil immersed CBN wheel system for the very best side grinding results with accuracies second to none.
The oil also assists in lubricating all moving parts keeping maintenance to a minimum.
The machine also comes with an oil mist filtration system and a fully automatic fire suppression system to mitigate against the risks of using an oil lubricant.
