Variable Pitch and Depth Bandsaws

July 07, 2021

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)

July 07, 2021

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

July 06, 2021

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.

How sawdust is worth $500,000

A Rotorua-based timber "super mill" is generating its own electricity in amounts sufficient to power a town the size of Whakatane.

The Red Stag Timber Company, which annually processes more than one million tonnes of logs at its Waipa mill, is using its waste wood as renewable fuel rather than trucking it to landfill and paying for its disposal – avoiding an annual power bill of up to $1 million in the process.
