We all know that part quality begins at the spindle. If you're manufacturing complex, difficult-to-machine parts, a collet-ready spindle should be standard equipment. Parts machined closest to the spindle bearings provide the highest accuracy and will greatly extend the life of the spindle and the tooling. A collet-ready spindle reduces wear on the spindle from less weight; and reduces chatter, extending the life of the tooling. Minimal overhang from the spindle bearings assure that spindle accuracy is transferred directly to the part being machined. This is the Hardinge Advantage. Hardinge collet-ready CNC lathe spindles are recognized around the world for providing superior part roundness and surface finish. The unique collet-ready spindle allows quick changeover from through-spindle bar work to second operation and piecework without the time penalties and alignment problems associated with non-collet ready spindle machines. Hardinge spindles offer flexibility for gripping parts of all shapes, sizes and materials. High-precision gripping options include: collets, step chucks, Sure-Grip® expanding collets, FlexC? collet systems, custom collets, Sure-Grip® power chucks and HCAC? dead-length collet chucks; all precision manufactured by Hardinge in Elmira, New York.. + Informações

Here is a comparison of the PreciseBits Precision Collet and the stock collet that came with my Hitachi M12VC Router. The stock collet had too much runout and I couldn't drill perfect holes nor profile perfectly sized shapes. With some trial and error, removing and reinserting the bits and stock collet, I was able to get the runout down to about 0.006" at the lowest. Most of the time it was around 0.009" or so. Considering that this is measured AT the collet basically, it means there's a ton of runout at the tip of the bit. I was also able to get the PreciseBits collet down to 0.0005" runout as opposed to the 0.001" in this video. This varies with each bit that I put in there, but you can definitely get very good results with a little bit of effort. They are available for purchase at www.precisebits.com Also special thanks to the http forum for lots of information as well as introducing me to these collets.. + Informações

zagar.com Zagar Inc - Workholding Collet Fixtures: Work holding is fundamental to any machining operation. Zagar collet fixtures both accurately locate and clamp work pieces at the same time. Steel housing components enable operation either hydraulically or pneumatically. More clamping force per square inch is applied on a work piece than any other method of clamping. Cycles are fast and safe. Fixtures are designed for use in severe environments. Bar stock, chips, and coolant can pass straight thru the fixtures. Set-up is made easy with a precision locating boss on each fixture's base. Work Holding Collets: Customize pallets are available for mounting groups of fixtures used in multiple part machining operations on CNC machines. Standard fixtures and collets range in size from # 3-C to # 44-C with round, square, hex, or custom ID's Up to five and a half inch OD Bar stock can fit thru our largest standard fixture and collet. Zagar collet fixtures are also used as draw-bar actuated rotating chucks as shown. In turn, Zagar automatic indexing fixtures are the fastest on the market. Indexing a work piece around it's center line in zero point two seconds. Keep us in mind the next time you're thinking about a work holding requirement. Please give us a call. We've been in the business of supplying work holding solutions since 1938 and some of our original collet fixtures that we built back then, are still in use. For more information on Work holding fixtures please contact us .... + Informações

This is an example of what can be done with the cool Celtic Fonts from this site: www.clanbadge.com I just used a stock pattern, but there are infinte patterns that can be made with the over 200 symbols! Since they're True Type Fonts, they can be used directly in most drawing and design programs. I used VCarve Pro 5.5. You can machine them different ways; I chose to V-carve the negative spaces and it givevs a good effect. What's cool about the fonts is that you can fit them to an arc just like any text, and create knot rings and such. I am using an Amana V-carve 90 degree insert bit, and PreciseBits.com collet and collet nut. The insert bits use harder grades of carbide which stay sharper longer, are reversible, and sharpenable. The PreciseBits collets and nuts are a huge improvement over stock collets, and greatly reduce vibration. That's important, because this V-carve bit is HUGE. I have the spindle at medium speed, and bumped the feedrate to 120ipm. For details about my home made CNC router, check here: www.youtube.com. + Informações

This video starts with a brief tour of my cnc lathe then shows how I make generic blank collets. I needed some collets for my gang toolblock to hold various size drills and boring bars. The first couple I made on a conventional lathe but realized that I would need many more. I also needed to test my cnc lathe (and to educate myself) with steel parts. I work mostly with aluminium. I think I need more spindle horsepower for the parting or to make some refinements to speed and feed. I have learned that you can't cut steel at aluminium speeds and feeds. You need to slow surface speed to approx 50%. Overall I am very pleased with the results. To complete the collets, I cut a 0.5mm flat on the side in the conventional mill, drill whatever drill size hole 3/4 the way through on a conventional lathe, and cut a 0.6mm slit on the centre (@ 45 degrees to the flat) with a slitting saw mounted in the conventional mill. The finished collets hold drills very well. The drills are clamped in the 40mm tool block with 2 x M8 304SS Caphead Screws.. + Informações

Hardinge designed an eccentric tool holder to eliminate tool breakage from misalignment. The Hardinge 1C Eccentric Tool Holder Collet Kit provides an ideal solution for indicating and centering small drills in machines that do not have Y-axis capability. The tool holder is purposely off center by five-thousandths of an inch to enable you to rotate and sweep your drill to the centerline position. The Kit includes the tool holder with draw nut, two machineable spacers, and four 1C collets in 1/16, 1/8, 3/16 and ¼ inch sizes. Tool holder is also sold separately.

Proper Collet Torque in ER collet chucks is essential to longer tool life. We often find that customers over-torque their collet nuts with the idea that the tighter the nut the better the holding power. Overtightening can lead to collet "twisting". Have you noticed how similar the angle on an ER collet is to your steep taper toolholder. They are both 16 degree, or 8 degrees per side, which is called a "free releasing" locking taper. When your ER collet reaches a specific torque value the longer taper will "lock" and the shorter 30 degree taper will 'twist" the collet which can cause runout and inconsistent tool life.

Performance With shrink fit toolholders vibration is reduced and cutting is noticeably faster and smoother. Manufacturing times can be reduced while maintaining the quality and accuracy demanded by today's competitive markets. How it Works Shrink fit uses the expansion and contraction properties of metal to provide extremely powerful tool holding. The bore is slightly smaller than the tool shank, and when heated it expands just enough to allow the tool to be inserted. When it cools, the contraction of the metal holds the cutting tool with 10000 lbs of force.
