9. After the rough cut has been completed, check the bore size.10. Adjust the cutting tool, to size, for the finish cut.11. Use the above procedure for the finish cut.Machining Thrust Surface
1. After the thrust surface has been built up with weld (do not use excessive amount of weld), use the following procedure to machine the surface.2. Place the cutting tool (facing) in the boring bar, and adjust the position of the tool so that it extends approximately 7.6 mm (0.3") past the bore diameter. The tool face must be parallel with the shank of the tool and extent past the shank.3. Make a rough cut until the weld begins to clean up. Determine the amount of material to be removed for correct location of the thrust surface. Install a dial indicator to read the cylinder travel. Continue to machine the thrust surface until approximately 0.5 mm (0.020") of material remains to be removed for the finish cut.4. Move the cutting tool out to machine a progressively larger surface. As the diameter increases, smaller widths of cuts should be taken. Continue to machine the thrust surface across its diameter until the entire surface is now ready for the finish cut.5. Machine the finish cut for the thrust surface.6. If necessary, sharp edges can be removed or a chamfer can be cut using one of the chamfering tools. For some applications, it may be necessary to shorten the tool by cutting off some of the shank.Final Machining Steps
After all faces and bores have been machined, remove the boring bar from the setup. Check the location of all machined thrust faces. Use a dial bore gauge to measure the diameter of all machined bores. If any bore or thrust face is not within specification, it should be finished to the correct size. If machined oversize, it will be necessary to weld again. After all faces and bores are correct, use a cutting torch to remove the setup from the work piece.Setting Speeds and Feeds
The correct speed and feed rates will depend on bore diameter, size of cut and hardness of the material being machined. A combination of speed and feed rates should be chosen that produce a shiny chip.The correct combination will ensure maximum tool life. If the chips begins to turn blue, reduce either the feed or speed until they become shiny again. If tool chatter occurs, it can usually be stopped by increasing the speed.Specifications
Power requirement is 45 ampere at 230VAC and 27 ampere at 460VAC.Hydraulic fluid capacity 150 L (40 gal)Weight is 408kg (900 lb) with hoses and electrical cables (no oil).Maintenance
Hydraulic fluid (CAT® Hydraulic Oil) HYDO
CAT® Hydraulic Oil is formulated with a balanced additive system, including detergents, rust inhibitors, antiwear agents and defoamers. It will offer maximum protection against mechanical wear, rusting and corrosive wear in all hydraulic systems.If different viscosities are required because of extreme ambient temperatures, one of following oil may be used, CAT® Engine Oil (EO) or CAT® Diesel Engine Oil (DEO).If CAT®
