Is Your Sawblade Restricting Optimizing Line Efficiency?

Print Friendly, PDF & Email

The Stiles System TM Opti-Kap and Dimter machines operate at high RPM’s, setting the standard for high-speed optimizing (defecting & sizing) of component pieces. However, most saw blades are not approved for use and do not perform well at this high RPM and cutting speeds.

Leitz optimizing blades are among very few blades approved to safely operate at up to 5,100 RPMs, and designed to continuously outperform competing blades. Customers who have made the switch to Leitz optimizing blades, provide very positive feedback:

“That’s the best blade we’ve ever used.”

“Who knew an optimizing saw could cut so clean!”

“My optimizing line now performs at optimal efficiency!”

A Sawdust-free Wood Shop? It’s Achievable with Dust Extraction Solutions from Leitz.

Print Friendly, PDF & Email

“Sawdust” is not only a daily clean-up and downtime issue, but excess dust can also lead to serious consequences for your employees, equipment, facilities, productivity, and the quality of your products.  The airborne dust within your facility is inhaled by employees, sucked into machine motors, and coats everything within the facility, all of which lead to serious health, maintenance, and safety issues citable by OSHA.

Wood dust is considered carcinogenic to humans (Group 1)(IARC). IARC states that wood dust causes cancer of the upper respiratory system and is linked to health issues related to the inhalation of bacteria, mold, or fungi within the wood.  Wood dust is also associated with toxic effects, irritation of the eyes, nose and throat, dermatitis, and respiratory system effects which include decreased lung capacity and allergic reactions. (Canadian OSHA 2017)

Dust on the workspace floor can cause slip and fall accidents, which account for more than 65% of (95 million) lost US workdays per year (US Dept of Labor). Dust is also highly combustible and can cause catastrophic explosions resulting in employee injury or death and destruction of facilities.

You may have invested in the best dust collection system available, with automated gates and spark arresting technology, but the problem originates at the cutting tool.  Most cutting tools are engineered to eject dust into the cutting path of the tool, and most machine “tool hoods” fail to efficiently trap and extract dust from the cutting process.  A large percentage of the dust simply flows in the airstream around the tool and is ejected back into the workshop.

Leitz utilizes dust flow control tool gullet designs (DFC) to neutralize dust velocity and trap it within the hood.  Once the dust velocity is neutralized, Leitz aerodynamic dust hoods efficiently extract virtually all of the dust from the cutting process and send it into your dust collection system.  Hoods are designed with easy tool access, and adjustable gate features, for ease of use and maximum encapsulation of the cutting process.  Leitz dust hoods are also available with noise-canceling technology, which reduces cutting related sound by as much as 5dB.

 

 

Leitz has long been a leader in engineering custom dust control solutions which provide a clean and safe environment for employees, improve product quality, and optimize process efficiency.  Whether you need to upgrade existing machinery, or have new machines in the budget, put our 20+ years of dust extraction engineering experience to work, ensuring the safest and most efficient tooling and dust extraction solutions possible.

When you combine machining and fiber-reinforced composite materials, such as carbon fiberboard and glass fiberboard, it can be difficult to achieve accurate and repeatable results. These materials present additional challenges to maximizing tool life and cut quality. Composite materials can wear down tools quickly. As tools become dull, they catch the fibers in the material, resulting in tears instead of clean cuts.

The Vienna University of Technology created the Fibercut Benchmark, a large-scale comparison of tooling performance, with the goal of determining which tool is most suitable for machine fiber-reinforced composite materials. The engineers from Vienna University of Technology evaluated the tools on the basis of fraying, delamination, and cracks and splits on the workpiece. In one hundred and twenty-four individual machining tests, they utilized three different workpiece materials: carbon fiberboard, glass fiberboard, and aramid fiberboard.  Eighty-six boring and cutting tools from sixteen different producers in total were tested. In the course of the Benchmark Study, each tool had to perform twelve processing tasks per test.

The tooling from Leitz out-performed the others machining these materials.

In individual tests with carbon fiberboard and glass fiberboard, Leitz submitted a diamond-tipped shank tool with an alternate twist. Andreas Kisselbach, Head of Research and Development at Leitz, explained, “Especially fiberglass being a very abrasive working material, tungsten carbide tools dull and quickly reach the end of their useful life.” In practice, diamond cutting materials are much more suitable when machining glass fiberboard.

Leitz solution with carbon fiber

Diamond tools typically outrun carbide tools by more than 20x and dramatically cut tooling and processing costs. Of course, special consideration must be given to proper application, operation, and service of diamond tools. The best tooling value can only be accomplished through precision service which increases the total service cycles and overall productivity of each tool. Precision tool service will also yield longer service life between sharpening or repair, resulting in fewer tool changes, less machine downtime and improved productivity.

Leitz diamond routers provide longer tool life, greatly improved service life, and high processing speeds to increase productivity and efficiency without compromising quality. Available in diameters as small as 3/8″, 2+2 and 3+3 wing design, and in various cutting lengths.

Leitz diamond tooling is maximized through experienced service technicians who use the finest grinding machinery, precision measuring and inspection equipment, dynamic balancing equipment, and the most current grinding know-how available to keep your cutting tools performing at optimal levels.

Proper Tool $ervice yields Critical Cost $aving$

Print Friendly, PDF & Email

 

Are you really buying the lowest cost-cutting tools? Caution, tool cost is not based on the lowest initial price, it’s based on the total efficient productivity provided by the tool.

The Real Cost of Tooling

Here’s how you should be calculating your tool costs:

New tool price + total service costs + tool change over costs / total linear feet of production achieved over the life of the tool.

The actual tool cost really comes down to the cost of cutting each piece of material. The key cost variables are total productivity between sharpening cycles and maximizing the total number of efficient service cycles.

If you simply evaluate tooling cost based on the initial purchase price and assume you are saving money by buying lower-priced tools. In reality, you are likely buying lower-performing tools, more frequently, and therefore, at a higher overall expense.

Better Tools + Better Service

Leitz is intensively focused on providing the lowest cost tooling, by ensuring our premium quality tools are used in the correct manner and returned to like new condition at every service interval. By sharpening tools on precision CNC grinding equipment and adhering to Leitz principals of proportional and relief grinding, we ensure your tools operate at top performance over the greatest possible service life.

Leitz proportional grinding procedures ensure the sharpest possible cutting edge while removing the least amount of cutting-edge material, thereby maximizing total available sharpening cycles.

Leitz proprietary tool relief geometry, and service relieving procedures ensure premium cutting-edge quality and sufficient tool clearance which minimizes friction heat build-up and thermal breakdown of the cutting edge.

High-tech final inspection and dynamic balancing equipment ensure you will NEVER be shut down due to tool geometry or performance issues.

If you’re searching for the lowest cost tooling solutions, Leitz will always provide the least expensive solution over the life of your tools!

How an Organization’s Growth Resulted in a Partnership for Continued Improvement

Print Friendly, PDF & Email

Technology plays an essential role in efficiency and productivity for today’s major manufacturers. Yet, when many manufacturers hit capacity, it’s assumed the only way to meet production schedules is to add extra equipment. The goal is to maximize current floorspace without having to add extra equipment or move to a larger, more expensive location until it’s necessary.

A growing, nationally recognized cabinet door and drawer box manufacturer was at production capacity and needed to make adjustments to meet their growing demand. In addition to adding two new CNC machines, they saw the opportunity to review their current machinery and technology and explore what could be done to optimize their entire operation. The manufacturer had been working with Leitz for tooling service and met with their representative to discuss what else they could be doing to get the most from their current machines.

A close look at MDF doors that have been cut with Leitz diamond tooling. These doors are ready to be sanded, glued, and have their foil pressed on.

Their Leitz representative recommended moving from an insert tooling system to the Leitz diamond routers and the Leitz ThermoGrip tool holding system. The newly implemented diamond routers system reduced machine downtime and increased tool life. Additionally, the ThermoGrip tool holders gave the customer a cleaner cut without the lines and imperfections they were experiencing with their other tool holding system, cutting down on multiple run-throughs and rework of the product.

With better quality cuts and increased tool life, the customer is not only saving money but has expanded their production capacity by approximately 50% on their current machines, more than doubling the number of truckloads of product they dispatch daily.

Additionally, the customer achieved a 30% improvement in tool life using the ThermoGrip system.

A comparison of the carbide insert tools the customer was using (left) and the Leitz diamond tooling in the ThermoGrip (right).

The solution from Leitz resulted in the highest level of production capacity without having to invest in more machinery or a bigger facility.  By looking beyond machinery, easy-to-implement changes in their tooling technology have made a huge impact for the Leitz partner customer.

Leitz is not only an industry leading manufacturer of advanced cutting technology but also a leading consultative technical provider. Leitz guidance is based on insight gathered from our multi-industry, worldwide perspective, and experience.  Our expert review, fueled by our belief that we can improve any cutting process, backed by our unconditional quality and performance guarantee, ensures our partner customers achieve the continuous improvement vital to their future.

What You Need to Know for a Successful Transition to CNC-Based Manufacturing

Print Friendly, PDF & Email

Manufacturers commonly buy CNCs because these flexible machines promise to replace several manual machines and dramatically improve the capabilities and efficiency of the production shop. This transition is, of course, very achievable, but because of inaccurate tooling and application choices, many buyers are missing out on fully optimizing their CNC machine performance.

When key machining principals such as proper part fixturing, achieving ideal cutting velocity and chip load are overlooked it can significantly affect process efficiency and ROI. Developing strong relationships with your router supplier and qualified tooling experts will prevent catastrophic errors and expedite the integration and optimization of this critical machine technology.

Utilizing existing hand routers and shaper tools

Many first-time CNC buyers will continue to use their inexpensive carbide-tipped tools on their new high-tech machine. These brazed carbide tools may “work,” but are generally not rigid, precise, balanced or durable enough to provide ideal CNC performance. Brazed carbide tools are, by necessity, much softer and less wear resistant than solid carbide or carbide insert tools. Tools designed around the CNC’s operational specifications and your output will yield more efficient and higher quality results.

Solid carbide router options

Solid carbide tools are also available in a range of hardness and durability levels that cannot be differentiated by eye. Carbide is essentially tungsten particles held together with a cobalt binder. Softer, less expensive routers are formed with 10% cobalt glue; harder more durable carbides generally have 3% cobalt concentration and may also include trace elements which resist thermal or mechanical dulling.

CNC operators may inadvertently settle for “softer/less durable” solid carbide tools because they’ve broken harder versions. Understanding why these higher quality tools broke (vibration, part movement, improper chip load, etc.) and addressing the issue will help you extend tool service-life and lower annualized tooling expenses.

Coated carbide tooling

Carbide coating options that improve surface lubricity, heat deflection, or increased cutting-edge hardness offer the next level of enhanced performance. These coatings are relatively inexpensive and generally provide much greater value to the user. Depending on how the tool must be sharpened, these coatings can sometimes provide extended performance over multiple service cycles.

Diamond tooling

Polycrystalline Diamond (PCD) routing tools can provide the lowest tooling cost per unit of production, but the higher initial tool cost and risk of damage can be intimidating. We recommend transitioning to diamond tools only after you are comfortable with the operation of your CNC and are enjoying problem-free routing with solid carbide tools. We also recommend forming a partnership with a PCD tooling supplier who can guide you through the proper utilization and care of these delicate yet durable tools. The baseline cost comparison for PCD vs. solid carbide routing tools is generally less than 7:1, but the average performance comparison should exceed 15:1. Used correctly, PCD tooling will dramatically reduce tooling inventory and required tool changes, while maximizing machine uptime and process efficiency.

Tool holding

Tool holding generally drives most CNC processing issues. Machine tooling start-up kits generally include basic collet chucks in one of three common collet versions (ER32, ER40 or SYOZ25/RDO35). Collets provide dimensional flexibility, allowing an operator to hold cutting tools with 1/8” to 1” diameter shanks in the same chuck body. Collets are, however, the first weak-link in an otherwise very rigid and precise machining process. The multi-directional torque applied to the collet when tightening or releasing tools can push the tools out of concentricity, and slight rotation or slipping of the tool will create internal damage which compounds tool run-out. Even the premium SYOZ25 collet system, which due to its 52mm grip length and 2.5-degree taper is the most precise option, can induce tool eccentricity and allow tool deflection. Collet systems also require significant maintenance and wear out over time, but issues which lead to poor tool performance are not always easy to visualize.

Eliminating collets

There are several collet-free chucking options available, but the easiest and most effective is Leitz ThermoGrip heat-shrink chucking system. ThermoGrip uses the thermo-mechanical properties of steel to grip tool shanks under tremendous pressure, effectively yielding a one-piece chuck and tool. Leitz ThermoGrip CNC chucking system provides the most rigid and precise CNC tool holding possible, optimizing cut quality, throughput and safety, while conservatively yielding $15,000 in annualized savings per machine shift. ThermoGrip ensures perfect tool concentricity under working loads, resulting in greater than 25% increase in tool life and at least 10% improvement in machine throughput at optimal finish quality.leitz, thermogrip, tooling, woodworking tools

We challenge customers to test their existing top running router bit style with the ThermoGrip. Once installed, their operator will immediately report:

  • Much quieter cutting
  • Outstanding cut quality
  • The ability to increase feed speed, without degrading the quality
  • Significantly longer tool life

 

Ultimately, this test is eye-opening for most customers, and a major step in optimizing the efficiency of their routing processes.

In conclusion

In order to optimize your CNC-based manufacturing process, you must be aware of available cutting tool related technologies and understand how to properly implement and utilize the technology. Tooling is the single machine accessory which can either limit or optimize your manufacturing efficiency and success. Having a knowledgeable tooling partner, with a worldwide perspective, will greatly enhance your ability to continuously improve your internal processes and keep your company at the forefront of the industry.
