Slim collets are very flexible and can respond differently to diversification and complications and applications. They have a chucking range of 0.07mm to 25.4mm and have high accuracy due to their flat shoulders pushing and gripping the torque of the taper. Slim collets are very versatile and can be used for a wide range of applications including milling, drilling, reaming, and rigid tapping. Other common collet types include R8 collets, hydraulic sleeves, HPH reduction sleeves, boring bar sleeves and morse taper sleeves. Each have their own application and applicable tool type.

4. Balance is extremely important in any type of machining (it is most important in 5-axis machining work). When your holder is balanced correctly, it helps ensure that the cutting edge is consistently engaged with the material, reducing chatter and poor surface finish quality.

A carbon fiber reinforced polymer is an advanced composite material which consists of two parts: a matrix and a fiber reinforcement. In this case, the reinforcement is carbon fiber, intended as primary structural component. Fiber can be continuous or short. The expression can be shorten in CFRP; “P” can stand for “plastic” also, not only for “polymer”.

In this scenario – driven by the demand of higher quality products, greater choice, flexibility – one of the most popular performance materials is carbon fiber reinforced polymer composite, thanks to its undeniable strength and stiffness: these characteristics when combined with the capabilities of professional 3D printing provide unrivalled manufacturing solutions.

Having the right tool holder in your machine can also significantly help with the repeatability of high-volume jobs and ensure that all your workpieces are machined to the same standards. This can increase productivity, improve process efficiencies and allow more high-volume jobs to run in a shorter time period, without the worry that workpieces will need to be scrapped due to not conforming to specified tolerances. Sometimes, when using tool holders that aren’t suitable for your machining set-up, it can cause the machine to stall or even damage the spindle – having huge cost implications and also causing major downtime whilst the machine is serviced or replaced.

Angle heads allow you to machine a feature in a hard-to-reach place without having to reposition the feature.

The WTO CoolSpeed® mini is a high-speed turbine-driven spindle. The CoolSpeed is driven purely by air, coolant or oil, and it does not have any gears, so it does not require any mechanical power from the milling machine spindle.

A huge factor that can impact the performance of a tool holder is rigidity. The higher the rigidity of a tool holder, the longer the tool life will be. The most high-performance tool holders will offer a combination of high rigidity and good dampening qualities, which allows the tools to work through vibration without decreasing the quality of the surface finish or damaging the tool.

Benz spindle speeders have been designed for the most demanding machining environments where the tolling is a crucial part of the production process. The standard Benz Spindle Speeders have a 1:5 ratio and a maximum speed of 40,000RPM.

Using a high-performance tool holder can also have implications on the outcome of a job or workpiece. By using a performance tool holder, you can decrease the expected run-out, hence increasing the accuracy of your tool and also the tool life. The amount of run-out that a tool will experience will cause it to wear due to the increased vibrations (vibration causes tool wear, spindle wear and tool failure, as well as a poor surface finish on your workpiece).

These versatile cutting tools are available in multiple point angles and are perfect for drilling, grooving, milling, spotting, and chamfering.

There are many different types of tool holders that can be used for different applications. Using the right tool holder for your job can impact many aspects of the machining process, including the speed at which the machine is able to run. If the tool holder you are using is high, with a low runout and high rigidity, it allows the cutting tools to run at a much higher RPM. The biggest advantage to this, and why we recommend high performance tooling alongside suitably high-performance tool holders, is the cost-saving benefits; saving the amount of downtime you will experiencing and allowing you to complete more jobs in a set time in a time-effective manner. On the flip side, if the tool holder you are using is not suitable for your set-up (for instance, using a standard ER collet chuck for high-speed cutting of a tough material), this can cause wear on the tool holder and also tool wear, potentially causing it to chip or even snap. Collets can also not be evenly pressed into the tool holder.

Arguably, one of the most crucial things to look at when purchasing a tool holder is the accuracy the tool holder provides. The accuracy of a tool holder can play a huge role in affecting the tolerance of the completed product and the machine’s ability to complete instructions and produce components to precise dimensions. When tool holders have increased levels of accuracy (usually characterised by low run-out, higher balancing and a higher quality material body), it is usually accompanied by improved productivity, better surface finish, lower downtime (due to not needing to replace tooling as frequently) and increased cutting speeds without sacrificing precision.

At the tip of the drill bit are the chisel edge, (the line across the point), the cutting lips (the leading sharp knife edges on a drill point) and the heels ( ...

Benz Jet allows you to slash your cycle times by up to 70%. Benz Jet uses an HPC-spindle technology, which is provided by Colibri spindles. The HSM jet spindle is quickly prepared for operation using a standard tool holder with a collet chuck.

A high-performance tool holder can offer several different benefits. Most high quality/high-performance tool holders will offer excellent rigidity, accuracy, high clamping power and dynamic balancing – this is all to suit the machine and the maximum spindle speed.

In 2015 Windform XT was replaced by Windform XT 2.0, with improvements in mechanical properties including +8% increase in tensile strength, +22% in tensile modulus, and a +46% increase in elongation at break.

When using carbide tooling (or any tooling which is defined as ‘high performance’, ‘premium’ or has a sizeable cost attached to it), it is important that the tool holding matches that of the tool making contact with the workpiece. Hydraulic chucks and heat shrink chucks (also referred to as shrink fit chucks) are two popular options when dealing with high performance tooling. Both offer higher run-out accuracies and increased tool life over conventional tool holders. Differences between the two are mainly the way in which the tool clamps into the holder; hydraulic chucks fill with hydraulic fluid which pressurises, closing the bore of the holder and clamps the tool in place, whilst shrink fit chucks use specialist machines to heat the chuck, which causes the chuck to ‘shrink’ and mould around the tool. For tapping, the equivalent high performance tool holder would be a synchro tap chuck.

In 2005 the company launched on the market Windform XT, polyamide based composite material carbon fiber filled, the first of this kind in the world, with unique mechanical and thermal properties enhanced by selective laser sintering (SLS) as manufacturing technology.

Over the years we have been asked all sorts of questions from customers who have varying levels of knowledge and experience. I have summarised below some of the most frequently asked questions that I am asked on a regular basis...

Collets act as the bridge between the tool and tool holder, so form an important part of the equation when choosing the correct tooling for a job. Selecting an ultra-high performance holder but complimenting this with a standard 10 micron run-out, would not only undermine the tool holder quality, but also potentially prove dangerous to the user, tool and job, especially if running at extremely high cutting data. It is therefore necessary to select a collet with a relevant level of accuracy to your tool holder and tool.

Another factor that can affect the efficiency of your tool holder is the gripping force. High-performance tool holders will have a higher gripping torque; the higher the gripping torque is on a tool holder, the more efficiently it will be able to run. A tool holder with a low gripping torque is more likely to run the risk of tool pull out.

High-performance tool holders also usually have a higher balance rating. A higher balance rating can affect the efficiency of work. When a tool holder has a high balance rating, the G value will be lower; the lower the G rating, the better the tool holder will be for your work (this can also depend on the application, the machine you are using and the cutting data of the tool you are using).

1. When you are setting up your tool holders, make sure that they are balanced as a complete assembly. A lot of tooling providers pre-balance their tool holders at the factory before they are sold, however, this can sometimes be inadequate, and it is better to make sure you balance the tool holders as a complete assembly.

Spindle tooling refers to a collection of tooling which fits into a manual or CNC machine’s spindle, hence the name ‘spindle tooling’. The end of the tool holder which connects to the machine will feature the same taper as the machines. Common tapers include BT MAS (JIS B 9339), SK (DIN 69871), HSK (DIN 69893), ISO (DIN 2080), Straight Shank and Morse Taper (MT). The connection chosen will have little bearing on the quality of the toolholder but is just a reflection of the make and model of the machine. At the other end of a tool holder will be the cutting tool.Usually, the cutting tool is directly clamped into the tool holder, with certain types of spindle tooling (commonly ER Collet Chucks) instead use an intermediatory to clamp the tool into the holder, usually a collet. A collet will have a clamping range, by which tools with diameter shanks within this range can be clamped. The collet is then clamped within the tool holder, which is then ready to be used.

Driven tools are a type of tool holder that are attached to the spindle and mounted onto the lathe turret – whilst standard lathing tools are held stationary against a spinning workpiece. They are capable of speeds above 6,000RPM and have a much greater efficiency than other types of tool holders, as they can dramatically reduce your workshop downtime and labour expenses. This is because driven tools allow you to reduce the number of operations needed to do a job.

3. Rigidity can cause problems when you are machining as it does very little to counteract the thrust loads caused by tooling, especially machine taps.

Gerardi also supplies a range of Evolution Line Angle heads which feature an interchangeable drive taper that allows the same angle head to be used on multiple different machines, simply by changing the input of the shaft.

Depending on the application or performance level required, there are different tool holding options available. If you’re using very cost-efficient tooling (for instance HSS or powder metal milling cutters or drills), it makes sense for a standard run-out holder to be used. This could be a basic ER collet chuck, end mill holder or face mill holder with standard 10 micron run-out collets. Of course, you can use a high precision collet in a standard tool holder, but you will be limited on the cutting data you can run a tool at and the vibration within such a set-up.
