The global pandemic has impacted businesses around the world, but for Aiguisatek, the impact was compounded by stringent local regulation in the Quebec province that all but shut down manufacturing in the area. Luckily for the Delson-based company, its investment in a Vollmer CHD 270 eight-axis TCT circular sawblade sharpening machine with the Vollmer ND250 automation station enabled the company to run unmanned production throughout the pandemic.
Founded in 1986 by Mario Dion and Conrad Goulet, the 15-employee company designs, manufactures, sharpens and services cutting tools, circular sawblades, router bits, cutter blocks, profiling tools and special tools for the wood, metal, paper, plastic and composite processing industries. Like many businesses, Aiguisatek started with one machine in a garage, with the founders focusing primarily on sawblades and router bits. Aiguisatek had a promising start, with the combination of highly skilled engineers and a Vollmer Akemat grinding centre.
Since its inception, the company has grown exponentially and expanded its product and service offering – something that has been supported down the years by six Vollmer Akemat circular sawblade sharpening machines. In 2011, the daughter and grandson of company founder, Conrad Goulet, took over the business.
Lisa Goulet and Jonathan Riberdy have since driven the business forward by moving to a new 14,000 sq ft facility, investing heavily in new machine tools and implementing a strategy to diversify into PCD cutting tools.
In 2013, the company realised its sawblade servicing department was reliant on ageing Akemat machines that required significant labour resource to keep up with its weekly demand of 350-400 sawblades. This was compounded by the increasing requirement for 80, 100 and 125mm split scoring saws that had to be manually processed.

The next-generation Vollmer arrives
The answer was a Vollmer CP200 four-axis CNC face- and top-grinding sawblade sharpening machine. Commenting upon this, Jonathan Riberdy says: “The demand for split scoring saws was increasing, and each blade would take up to 15 minutes to process manually. Buying the Vollmer CP200, we reduced production time to 3-4 minutes. This alleviated the pressure and capacity demands on both the Akemat machines and the staff.
“The Vollmer CP200 also gave us a lot more – it improved our re-grinding and service quality, it improved our throughput, and the versatility of the machine allowed us to produce blades with more complex geometries.
“Back in 2013, we had several sawblades that were problematic. These saws had to be subcontracted out for re-grinding. Just one example was a 10-in diameter sawblade with a fine pitch of 130 teeth. The CP200 enabled us to bring challenging blades in-house and eliminate subcontract costs and the reliance on third-party suppliers. The CNC control unit and the software on the CP200 also made the set-up and programming extremely quick and efficient.”
Solving growth challenges with Vollmer
In 2015 Aiguisatek expanded into PCD cutting tools, increasing its offering and market share with existing customers as well as winning new clients. Since this diversification, Aiguisatek has witnessed +25% YoY growth, expanding beyond its local customer base to support clients across the Quebec and Ontario areas.
Of course, such aggressive growth, not just in PCD tooling but also in TCT sawblades, required additional investment. So, in 2019, the company acquired a Vollmer CHD270 eight-axis tooth top- and face-grinding machine with the Vollmer ND250 automation solution, as part of a $1.5m investment.
Alluding to this growth, Aiguisatek president Lisa Goulet says: “PCD tooling has been a gamechanger for us and it has accelerated growth. In a short time, the breakdown of our products is now 35% PCD and 65% carbide tooling. Simultaneously, our TCT sawblade department has grown by an average of +15% YoY and we are now servicing over 1000 sawblades a week.

Almost 90% of our customer base is in the woodworking industry. We now have three staff delivering/collecting saws and tools daily to manufacturers of everything from cabinets and furniture through to windows, doors and the construction industry.”
With production requirements increasing from 350 to 1000 blades a week, the Vollmer CHD270 was a necessity. Commenting upon this, Jonathan says: “While increasing production output, we had ageing machines and two experienced but also ageing operators, running seven machines non-stop every day.
“This bottleneck was a stressful environment for the operators, whose vast experience kept inconsistent quality to a manageable level. We knew we needed a solution, and the CHD270 provided it.”
The benefits of Vollmer and automation
The CHD270 installed in 2019 can process sawblades from 3.15-33in in diameter, while the ND250 four-axis double-gripper automation cell has five carriages to accommodate up to 450 sawblades or a maximum load of 1500kg. This changed the game for Aiguisatek, a growing business in a stagnating marketplace.

Recalling the situation, Jonathan continues: “Saw servicing changed overnight. We went from two operators running seven machines non-stop to one operator working across the CHD270, the CP200 and one or two Akemat machines. With the Vollmer CHD270, our operator can spend two hours loading and unloading around 150 saws and then setting the machine to run for 24 hours unmanned – giving the operator time and capacity to work on other machines.
“The Vollmer CHD270 processes one saw at a time, so it’s not as fast as two men running seven machines simultaneously all day long. However, we used to have two men working 10 hours a day to produce 150 saws on seven machines – now the Vollmer CHD270+ND250 runs 24 hours a day, six days a week, giving us the same weekly production capacity from one unmanned machine as we used to get from two men and seven machines.
“Instead of running seven machines simultaneously for 10 hours, the CHD270 reaches the same daily output by running through the night unattended. Not only does the Vollmer make the time and output up through weeknights, but it runs unmanned over the weekend too. Now, we run about 10-15% of our blades through the Akemat machines for a couple of hours a day, with the CHD270 doing most of the saws.”

Exceeding quality expectations
Aiguisatek has built an enviable reputation for its service, quality, consistency and innovation, and Vollmer has been pivotal in supporting this. Jonathan says: “The Vollmer CHD270 instantly improved the quality and consistency of our sawblades.
“With in-cycle blade probing and automated wheel dressing, the repeat quality really surprised us. It was a huge difference when compared to our older machines. When combining the stability and stiffness of the CHD270 with its in-cycle calibration and automation, the quality is outstanding.”

Like the CP200, the CHD270 has a user-friendly interface that simplifies programming, with almost limitless tooth geometry opportunities. As Jonathan states: “Our price point may be a little more expensive than our rivals, but we deliver quantifiable savings with test reports. Our expert engineers will consult with customers on applications and material types to maximise performance and precision, and reduce costs. The ability to easily create a variety of geometries with unsurpassed quality on the CP200 and CHD270 supports this service.”
By creating test reports for clients, Aiguisatek can follow the lifecycle of sawblades from new, through to the final re-grind before blade replacement. Compared to its rivals, Aiguisatek can re-sharpen blades up to 20-25 times before renewing, whereas competitors can only achieve up to 10-12 re-grinds before a costly blade replacement. Aiguisatek sawblades can achieve up to +50% greater tool life, and they can increase cutting metres by more than +30% per re-grind.
This is credit to the combination of expert on-site engineers and the production processes on the Vollmer CHD270 and CP200. Concluding, Jonathan says: “With the Vollmers we know exactly what we are taking off each tip every time we do a re-grind. There is no inconsistency, and this gives the blades a much longer tool life. For new customers that query our price point, we show them the Vollmer machines their blades are being made on – and that fills them with confidence in our quality.”

… and the pandemic
For Aiguisatek, the pandemic has been a painful period that has seen some customers enter liquidation, a factor compounded by pandemic market conditions and regional legislation that has restricted trade to ‘essential manufacturing business only’. Commenting on this, Lisa Goulet says: “At Aiguisatek, we had challenges like every business.
“At the height of restrictions, our business was down to just 30%. The challenge for us was satisfying this low level of production with no staff. Our staff were not at work due to safe-distancing regulations, and Jonathan and I ran the business between us.”
Jokingly, Lisa concludes: “If it wasn’t for the Vollmer CHD270+ND250, Jonathan would have needed to work more than 100 hours a week on the shop floor to get the sawblades out of the door for our customers!
“It is situations like this that highlight the benefits of automation and investing in quality machines. Moving forward, we are happy to report that we returned to pre-Covid business levels last year, and, as of October, our annual growth rate of +25% is back on track.”
It looks like Aiguisatek may need more Vollmer technology soon …
