		Custom Chuck This chuck was a 12 inch (12) jaw wedge key chuck that was used to hold (3) different sizes of tires. The biggest benefit this chuck has is the ability to chuck different sizes of bores varying .5 of an inch. With exact repeatability of each jaw on the internal wedge, the chuck repeated less than .0001.

		Draw-Down Chuck This chuck is a 8 inch, 3-jaw draw-down chuck. Our customer needed a way to ensure part was being held tight against the part stop during machining. Our customer was machining a gear carrier where repeatibility had to be less than .0005. We proposed this design to replace their current 3-jaw sliding chuck that was not performing to their needs. This chuck was fit into the old machine envelope with exact part stop heights and exact chuck diameter and weight specifications.

		ID Diaphragm Chuck This chuck is a 9 inch, 6-jaw I.D. diaphragm chuck. Our customer needed a way to perform an audit on their production ring gears they were machining. This chuck was used and developed to hold on the I.D. of the ring gear so various dimensions could be checked. This chuck had to repeat within .0002 in order to assure proper readings from the audit machine. There were (2) different sized ring gears, so all that was necessary for part change over was replacing the (6) top jaws that has (2) bolts per jaw to hold it in place. Even with part change over, the chuck repeated within .0002.




		ID Diaphragm Chuck This chuck was used to hold the I.D. of 5 different parts, all having different bores. With having (10) ears on the chuck, there were (10) different inserts that we replaceable, where part change over could be done in less than 15 minutes. With changing each set of inserts, the chuck was repeating within .0002 on each part.




		Large Single Taper I.D. Collet Chuck This chuck was designed to balance (3) different sizes of brake drums. This is an 18 inch chuck that had to be able to withstand a .25 inch deep milling cut for balance correction. By using quick change jaw inserts on the collet, part change over was done by replacing the jaw inserts, not the entire collet. By using our latest CAD and CAE software we were able to determine if the chuck could handle that depth of cut. This chuck had a built in air cylinder with springs to clamp the part. The chuck repeated within .0005.

		O.D. Diaphragm Chuck This is a (4) jaw - 6 inch O.D. diaphragm chuck that was used to hard turn the I.D. of bearing caps. This chuck accommodated (3) different sizes of the bearing caps, where change over was as simple as removing (1) screw from each jaw. This chuck had a positive part stop with a part ejector that was used in a system with robotic load. There was also a built in air cylinder which incorporated push-pull capabilities. The chuck was built with stir- around screws where the chuck was proven to repeat within .0001 TIR. This particular chuck was used to replace a (3) jaw sliding chuck where performance and maintenance was timely and not cost effective. Being this chuck was used in a grinding application, the previous chucks were ...




		O.D. Diaphragm Chuck This chuck is a 12 inch O.D. diaphragm chuck with 12 ears. This chuck is a push-pull chuck that allows the user to vary chucking pressure depending on part geometry. The slots are sealed to eliminate any swarf to hinder chucks application. The chuck comes with 12 replaceable jaws that can chuck any part from 10 inches an below.




		O.D. Diaphragm Chuck This chuck is a 12 inch O.D. diaphragm chuck with 9 ears. There is no grinding of the jaws at part change over and the chuck still repeats within .0002 tir.




		OD Collet Chuck This chuck was used to straighten drive shafts prior to balancing. The chuck held on the O.D. of the slip-yoke with the collet having manual load. The collet was made where the part stop was inside the chuck. When the slip-yoke was pushed into the chuck, it pushed the collet down the taper, chucking the part.




		OD Collet Chucks This chuck was designed with (2) independent collets. There is a smaller collet on the inside that locates and clamps a small internal bore on the piece first before the large collet clamps the piece for turning. This chuck is 18 inches in diameter as well as having concentricity of .0005".




		Replacement Top Jaws • Manufactured to print • Designed to hold your specific piece • Design top jaws for any chuck • Guaranteed to be within OEM specs or better

		Single & Double Tapered Collet Chucks This chuck was designed for ease of part change over. There are (2) different parts being held and our customer needed a quick way for part change over. There are (6) part stop posts that are stationary. The left picture shows the chuck while it had the long double taper collet configuration. Change over was as easy as replacing the gold body with the one on the right in order to hold the second part. The chuck had a built in air cylinder with springs to clamp the part. The chuck repeated within .0002.

		Special Flatted I.D. Collet Chuck: Flat-Lok Special This chuck was designed to hold an OP 20 part. The body was re-designed along with a special part stop to ensure proper locating every time. The part seen on the right was a production run where tolerances were .0002. There were (2) different sized bores needing to be clamped on, where we made part change over as easy as changing out the collet.

		Wheel Chuck This chuck was designed to balance various sized wheels. We had to have .4 inches per side travel along with a chuck to hold 3 different sizes.
