Frequently Asked Questions:

Q: What is the “carrier” concept?

A: The “carrier” concept is a method for machining parts that uses an amount of sacrificial material, the “carrier”, to hold onto a part while the top and sides of the part are machined to finish size. The part is then re-positioned with the machined top portion down and clamped on the finish machined sides using hard jaws or nested in soft jaws, then “carrier” material is machined off and any other finish machining is completed on that side of the part. This process allows completing a high percentage of parts in just two clampings. The most efficient version of this process uses Talon Grip Vise Jaws and requires no pre-machining of the blank material in order to effectively hold the part while machining aggressively.

Q: How are TalonGrip Systems Jaws used in the “carrier” concept?

A: Talon Grip Jaws are used to clamp a part in a vise using only 1.5mm of material to grip the part while still allowing for machining with aggressive speeds and feeds.

Q: Why would I use TalonGrip Systems jaws instead of the regular jaws that came with my vise?

A: Regular jaws are smooth and will not hold the part as well while machining aggressively unless much more than 1.5mm of material is clamped in the vise. TalonGrip Systems Jaw grips actually bite into the material to prevent the material from being so easily pulled out of the vise when aggressive speeds and feeds are used.

Q: Will the TalonGrip Systems jaws leave marks in my parts?

A: Yes, the grips bite into the material, that’s how they hold on to the material so well. Using the “carrier” concept, this material (and the marks) is removed in the second or later operations.

Q: Why are the jaws not hardened?

A: Mitee-Bite leave the jaws soft so that if you need to cut into them to separate the carrier of multiple parts to eliminate a sawing operation, you can mill right into the jaw without damaging the cutter. DO NOT mill into the grips, they are hardened, and will damage your cutters. Mitee-Bite will be offering a case hardened version of the steel jaws, very soon, for those applications needing additional resistance from wear and damage from heavy steel or stainless steel parts, or heavy handed operators.

Q: What are the extended jaws used for?

A: The extended jaws give you an extra inch, per side, over the stock width to allow longer parts to be clamped. Also if you have 6”, plus, long parts, there is room for the stop. The extra length will also allow more parts to be clamped in the jaws at once.

Q: Is 1.5mm enough material to clamp on my part while machining?

A: 1.5mm is enough for most applications if the bottom of the material has only a small edge break or corner radius of up to about 0.75mm max. All parts shown in the videos on the Mitee-Bite Talon Grip YouTube Channel, were machined gripping on only 1.5mm. However, if the edge condition of the material is rounded quite a bit, it might not be enough. Also softer materials like some plastics and non metals may need more than 1.5mm of grip height to be gripped adequately

More grip height can be achieved by removing the grips, stops and their screws from the jaws, clamping the vise tight and machining off up to 0.38mm of material from the top of the jaws. This will allow the grips to stick up higher than normal and grip more material. No more than about 0.38mm should be removed as the grip geometry will only allow gripping on about 1.9mm max.

Q: What materials can be clamped with the jaws?

A: Any material that has a Rockwell “C” hardness of 40 or softer. Aluminum, brass, bronze, copper, composites, plastics, mild and carbon steels, high nickel materials, inconel, titanium, stainless steels, tool steels have all been gripped and machined successfully with the TalonGrip Systems Jaws. Brittle materials like some plastics, ceramics and composites may develop cracks and chipping from the grips. You will have to determine for yourself if the Jaws and Grips will work in those types of materials.

Q: How parallel are the “built in part rest surfaces”?

A: Mitee-Bite machine the jaws to within 0.05mm of parallel, to the bottom of the jaw. They will, normally, not need to be even this close as you will, normally, be removing the gripped “carrier” material anyway. If you need them more parallel for a special application, this can be achieved by removing the grips, stops and their screws from the jaws, tightening the vise with the jaws installed and machining a small amount of material from the top of the jaws. Or you can match grind the tops to the bottom on a surface grinder.

Q: Will the TalonGrip Systems Vise Jaws fit my vise?

A: Most likely! The jaws have been designed to fit most common machine vises. Determine the hole spacing and size of your existing vise jaws and compare them to the size specification chart.

Q: How do I install the TalonGrip Systems Vise Jaws in my existing vise?

A: Quit laughing, we were actually asked this question at the Santa Clara Tool show! Remove the bolts from the existing jaws of your vise and take the jaws out of the vise. Clean the vise and make sure the area under the jaws is clean and has not been damaged. If not damaged, then clean the Talon Grip jaws and install them in place of the just removed jaws, insert the jaw screws and tighten adequately. Position the grips and stop(s) as needed for your application, insert the flathead screws provided and tighten to the torque setting recommended (3-5 newton meters).

Q: How many grips do I need to use?

A: Good question! Usually less than you might think. The grips need to penetrate the material to really work best, so if you use too many, the increased surface area of the grips may not allow them to penetrate with the force available from your vise. If you have to use a cheater to get adequate penetration then you are likely using too many. Most single parts can be clamped really well using two grips per side. Some small parts can be clamped using only one grip per side. Larger parts may require up to 3 grips per side. If properly spaced and you have good penetration 3 grips per side will allow some pretty big parts to be machined very aggressively. You will be amazed at how well they hold!

Q: How are the stops used?

A: The stops are at the same height as the grips, and so, should be under the cutter when machining. They can be reversed to provide a little extra adjustment. The corner of the material is placed against them to locate the material laterally before clamping. Multiple stops can be used in a jaw set to position multiple parts.

Q: How tight should the grip and stop screws be?

A: Torque the flat head screws to 3-5 newton meters.

Q: How tight should material be clamped in the jaws?

A: Tight enough that the grips penetrate the material at least 0.25mm – 0.38mm and usually not as tight as you would with smooth hard jaws. For softer materials more penetration is desired.

Q: Can I hammer down the parts clamped in the jaws?

A: NO!!! If you do, you WILL BREAK the grips. You do not need to tap or hammer the material down when using a “carrier”. Just set the material on the rest surfaces, against the stop and tighten. You should also not hammer on the vise handle to tighten the vise.

Q: What cutter speeds and feeds should I use when using the jaws?

A: This of course will depend on so many factors we could not hope to address them all here. You will have to determine these based on your application. Look at the videos again on the web site to see some real demonstrations, this may help you. In any case you should never exceed the recommended speeds and feeds supplied by the cutter manufacturer or your machine’s capabilities.

Q: Can I modify the jaws to suit my application?

A: Yes. You will void any warranty of course, but you can modify them to suit you needs. That is one of the main reasons they are soft.

Q: How do I clamp on more than 1.5mm of material?

A: You may either shim the grips up 0.38mm max or remove 0.38mm max from the top of the jaws to achieve a 1.9mm grip height. Any more and the grip geometry will prevent proper clamping of the part. Mitee-Bite will soon offer, for sale, grips that will have 3.175mm of grip height. These will fit all existing TalonGrip Systems Jaw sets and will be available in sets of two or more.

Q: How do I clamp on less than 1.5mm of material?

A: Be very careful, but you can grip less than 1.5mm on a good edge with minimal edge break on your material. Gripping power is reduced as the grip height decreases, depending on material. To achieve this you must modify the jaws by machining the grip groove deeper to allow the grip to set lower. BEWARE!! If you machine the groove deeper you will not be able to use the stops. You will break off the stop tabs when you tighten the screws. Remove the grips, stops and screws , of course, before machining the grooves deeper. Keep the groove width the same as the existing groove, or you may damage the grip, screw or jaw when clamping with the vise.

Q: How do I clamp on thin parts without distorting them?

A: Use common sense here, thin parts are always a problem to clamp without distortion. If the part is thin enough to bow when clamped but will spring back to normal when unclamped, you can possibly clamp the part tight enough to penetrate the material with the grips, then loosen the vise and re-clamp the part not so tightly without moving it. The grips teeth will still be in the material, and you can machine the part with caution and common sense dictating the speeds and feeds.

Q: Can I buy extra grips or stops?

A: Yes. Grips come in sets of 2 and stops are sold individually. Contact your local distributor for pricing.

Q: Can I buy replacement jaws?

A: Yes. See the “Jaw specifications” chart for the part number. They are also available through your distributor.

Q: Can I clamp and machine more than one part at a time in one set of TalonGrip Jaws?

A: Yes. The picture and videos on the web site show applications with multiple parts being clamped in the jaws. The extended jaws allows extra room for more parts. Unlike regular jaws, you can clamp on three or more parts and not have any loose parts as you would in regular, smooth, hard jaws. The grips will penetrate into the material, so slight differences in material width will not prevent all parts from being gripped. Be careful! When clamping three, or more, parts, make sure that the material width does not vary too much. You can also use multiple stops in one set of jaws. Depending on the size of the parts, try and use two grips per side for each part. Smaller parts can be clamped using only one grip per side.
