Products Dial Indicator Pin Chuck The Dial Indicator Pin Chuck was developed to save time by avoiding the need to make or modify dial indicator contact points for measuring small holes and slots. It provides a quick and easy method for measuring these features using gage pins, items found in all machine shops and quality control departments. Specific features of the Dial Indicator Pin Chuck include: Okuma & Howa ACT 3 CNC Lathe PURCHASED 1985 1.75" through collets, 10" chuck (6" diameter capacity) Powerful, 15 horsepower, 3500 rpm spindle, Fanuc 6TB control Support Equipment Honing Cold sawing Accepts a wide range of gage pins from.010 dia. To.135 dia. to accommodate many hole diameters and slot widths. Eliminates making contact points saving valuable production and inspection time. Thumbscrew locking mechanism provides fast changeover. Internal V-block design ensures parallel gage pin positioning. Universal 4-48 male thread fits most dial indicators. Very short overall length saves available indicator stand height. Pays for itself in one use. They are sold by the pair. Mastercard & Visa card purchases accepted by phone Vibratory Finishing Plastics Heat treat ask for the Pin Chuck 1 800 770 8517
Page 4 Page 9 Products Optical Rings, custom Optics components such as filters, windows and lenses are often cemented into protective metal rings, usually made of aluminum. Rings can be one or two part (one close-fitting inside the other), They can be black anodized for non-reflectivity. Select from the chart online. Special variations are easily machined. We stock some of these sizes in small quantities. Rings can also be manufactured in custom sizes with threaded outside and inside configurations (for use with retaining rings).

Page 8 Page 5 Capabilities Products Our principal specialty is CNC turning. -CNC Swiss to 1 diameter (dual end-working, main and subspindle indexing, side and end working with rotary tools, 7 turning tools). Machining quantities of 50 to 20000, depending on complexity. -CNC 2 axis bar work from.010 diameter to 2 diameter, slugs up to 6 diameter. Machining quantities from 1 to 5000. -We machine a great variety of materials, a list comprised of 8 aluminum alloys, 11 stainless alloys, more than 6 copper alloys, more than 6 exotics, 11 steels, and at least 16 varieties of plastics. See Materials on page 11. -We specialize in cast acrylics, as well as their vapor polishing and annealing. -We do small part microscopic machining, inspection and deburring. -We have support capabilities including FeatureCAM CAD and CAM design, honing, cold and abrasive sawing, vibratory finishing, and abrasive blasting. -We know TIG lathe welding, brazing and soldering. Rod ends, miniature nickel silver Our rod ends are made of 792 Nickle-Silver, which is actually a Copper/Nickle alloy. The ball is 316 stainless, with a 2mm thru hole. The body is internally threaded with an M3x.5 thread, The rod ends are specially lapped to eliminate ball backlash, and may require additional lapping dependent on the use to which they are put to achieve optimum fit. Part #04111501 Thermowells, custom We have made tens of thousands of custom thermowells for various customers, and we can help you design one for your special purpose in various materials from aluminum to plastic. In general, thermowells are used with temperature sensing devices, isolating the sensor from fluid or gas, possibly made of a good heat conductor such as brass or aluminum. Stainless is often used in demanding environments, though it is a poor heat conductor. In that case the material in contact with the chemical environment is thin to lessen heat transfer time. Titanium can be specified for good chemical resistance and heat conductivity. Ask for Thermowell Generic drawing
