The , stainless steel pin media, can be added to a single or multiple tubs along with liquid solution, cutting fluid or even water. The parts that require deburring are added to the container and the desired cycle time and other parameters are dialed in to the controller.  

When it's time to separate the demurred parts from the media, simply pour everything through a strainer that sits in a second container.  Place the strainer and the container back in the tub of the sPINner unit, momentarily turn it on and all of the magnetic pins are sucked through the colander/strainer.  And you're ready for your next batch of deburring parts to be added.
​
Here are a few usage tips to operate the Magnetic Deburring Machine:

• When working with hard materials that require more power, choose media with a diameter of 0.5mm or larger.
• For softer materials, use media with a diameter of 0.5mm or smaller.
• When dealing with parts that have small holes and crevices, opt for 3mm length media.
• Always make sure that the diameter of the media is smaller than the holes present in your parts.

By following the recommended operation procedure and usage tips, you can effortlessly achieve optimal results, ensuring your parts undergo a thorough and efficient deburring process.

There are some distinct advantages of Techniks Spinner Magnetic Deburring Machines over Manual and Vibratory Deburring

Operator Safety
Manual deburring exposes workers to potential ergonomic and safety hazards, including repetitive strain injuries and exposure to sharp edges. Vibratory deburring machines require regular monitoring and maintenance to ensure safe operation.

Techniks Spinner Magnetic Deburring Machines prioritize operator safety. By automating the deburring process, they reduce the need for workers to handle sharp-edged components manually. This minimizes the risk of accidents and workplace injuries, creating a safer working environment.

Cost-Efficiency
Manual deburring is labor-intensive and can be costly, particularly when skilled operators are required for precision work. Vibratory deburring machines, while more efficient than manual methods, consume significant amounts of energy and may require expensive abrasive media replacements.

Techniks Spinner Magnetic Deburring Machines strike a balance between precision and cost-efficiency. Their automated operation reduces labor costs, and their magnetic field eliminates the need for abrasive media, as a result of the the long life of the stainless steel media, saving on consumables. Over time, this cost-saving advantage becomes evident in reduced operational expenses.

Environmental Impact
Vibratory deburring machines often generate noise and vibration, potentially affecting the working environment and requiring soundproofing measures. Additionally, the disposal of used abrasive media can have environmental implications.

Techniks Spinner Magnetic Deburring Machines operate quietly and without vibration, creating a more comfortable and environmentally friendly workspace. They also produce less waste, as there is no need for disposable abrasive media, contributing to sustainability goals.

It's that time of year for IMTS!

​Here's a preview of some of the products that are going to be featured during the International Manufacturing Technology Show September 12-17.  You can see all of these new products and talk to the manufacturers in the Tooling & Workholding Systems Pavilion in the West Building Level 3. 

Supermini Set. Horn USA is featuring the Supermini tool holder system with face clamping as a set, in response to customer requests for different tooling system heights. With this holder variant, clamping is not carried out via the lateral surface of the cutting insert but via a clamping wedge on the face. This results in a greater holding force on the insert and thus high rigidity of the entire system. This increases repeatability when changing the insert and provides better utilization of the available space. This is a big time saver on Swiss-type lathes, as the user can change the cutting insert without removing the tool holder.

New carbide grades for system DAH8 - Horn USA is expanding its range of carbide grades for its DAH milling system to enable its use for machining a wider range of materials. The new grades SC6A and IG6B complement the tool system for high-feed milling. The SC6A grade is suitable for machining the ISO M material group, as well as ISO S materials as a secondary application. Horn has developed the IG6B grade for machining the ISO P group, while it is also suitable as a multipurpose grade for other material groups.

The 2021 Techniks Catalog is available for download now!!  It features the MegaFORCE Retention Knobs that we talked about in our February Article as well as the new Triton Hydraulic Holders. 

The only thing standing between a job well done and catastrophic failure is the retention knob. MegaFORCE Retention Knobs are designed to deliver superior performance and enhanced safety for the critical connection between your machine spindle and the tool holder.  Retention Knobs are subjected to extreme pulling forces of up to 5,000 ft. lbs. Over time, this stress exploits weaknesses in the retention knob and can lead to breakage.

MegaFORCE Retention Knobs have been designed and manufactured to increase the strength and durability of this critical connection.

​The longer overall length engages threads deeper in the tool holder, reducing taper swelling and maximizing taper/spindle contact for the most rigid connection. MegaFORCE also features a redesigned, blended radii for improved overall strength, making MegaFORCE the strongest high-torque retention knob in the market.

The Triton Hydraulic Holders by Techniks feature a new hydraulic design to provides excellent vibration damping properties, so tools run longer and quieter and produce superior surface finishes. Triton provides 3.5X clamping force of standard hydraulic chucks.

Triton hydarulic chucks are charged with hydraulic fluid in a vacuum chamber to eliminate air and gas from the system. Coupled with a redesigned oil sealing system, Triton chucks are built to provide maximum holding power for years!

As carbide end mills gain higher and higher speeds and metal removal rates there has also been a trend by round tool manufacturers to tighten up the tolerances on both the cutting diameter and the shank diameter to improve concentricity. At the same time, shrink fit holders have become more and more popular because they hold a tighter concentricity as well.  To achieve this both the shank and the bore now have similar surface finishes and this has led to a problem  The tools pull out in the cut.

Shrink fit holders are the most accurate for TIR as the toolholder engages completely around round shank tools with a bore tolerance of -0.0001" to  -0.0003".  As high performance end mills have tightened shank tolerances to the same range of -0.0001" to  -0.0003" they have used finer and finer grain grinding wheels which give the shanks a 'shiny' appearance. 

Shiny means that the superfinished shank has a lower coefficient of friction. So, although the TIR is tighter, the shank is more "slippery".   End mills traditionally had surface finish of about 8 μin on the tool shank. But that's changed.  It's been recommended that tool shanks used in shrink fit holders should not have a finish finer than 16 μin. for optimum holding power, but tell that to the guy who just superfinished the end mill to a super cocncentric tolerance that you don't want it looking that good.

Everyone know that the last thing you want is for the end mill to slip in the middle of a heavy cut or on the finishing pass of a high tolerance part.  These 'hi performance' end mills, often times have higher helix angles which are great for ejecting chips but also create a higher pull out force on that slippery shank. And reducing the helix angle is not the answer.

We  already know that the gripping pressure is a function of the interference between the tool shank  and the shrink fit toolholder bore. Most shrink fit holders have a already bore surface finish of between 12 μin. and 16 μin.  So they are ground to a very high tolerance and have about the same surface finish as the toolholder shank.

End mill manufacturers and machinist have tried a variety of methods over the years to stop the tools from pulling out. This has ranged from grit blasting the shank to rubbing chalk on the shank, but most everyone in the industry has felt that the problem really needs to be addressed by the longer life toolholder rather than the replaceable cutting tool.

We've had several inquiries regarding steep taper rotary toolholders specifications.  Below you will find all of the technical reference information related to V-Flange Tooling Tapers and dimensions.

BT-40 Shank is also known as: JMTBA MAS-403 "BT", JIS B 6339 - 1986, JIS B6339 - 1992, and ISO 7388/1 - 1983.

The spindle interface JIS B 6339 as the traditional interface for milling spindles distinguishes itself through it robust design. Its field of application ranges from fine machining to heavy duty roughing. The tool holder is pulled in the milling spindle with the help of an additional pull stud.

The centering takes place via the taper contact. Therefore, the JIS B 6339 interface is primarily suitable for applications with a spindle speed of up to 12,000 rpm in an unbalanced condition.

Many operators do not know why it is necessary to replace their tooling, or have the experience to tell when it is time to do so.

Determining if toolholder components need to be replaced is not a difficult task, but does require that the operator knows what to look for.

A worn out holder will not provide good accuracy and will quickly wear out your cutting tools. Worn tooling causes poor surface finish, and may damage your spindle.

This article will discuss the following types of causes and types of wear.

1. Spindle Mouth Wear
2. ATC Alignment Issues
3. Taper Wear / Fretting
