Rottler would like to announce the newest model CNC machining center to the Rottler family of CNC machining centers. Our new F68ATC machine comes with a full enclosure, 24 piece tool changer and coolant capability. Machine has a 10hp 5,000rpm spindle motor along with ability to read G-code programs. The specialized Rottler software also allows programming of block machining functions easily and with no prior G-code programming experience.

Water Pump Machining:This past quarter we were involved with a machining project that aided in the repair of water pumps. Internally there is an impeller that circulates water through the pump at a very rapid rate. There is an isolated area that creates a lot of wear on the surface of the material. SCR will put weld on the affected areas. With the fixturing and the programming that we provided them they are now able to utilize their F99 to re-cut the pumps, after weld, to get them back to their original state. With the DM control we created a simple 3-D surfacing routine which provided a perfect blend with the weld and original surface.
New Block Lightening Program: For the past six weeks we have been working on a new block lightening program for the Dart "Big M" big black Chevy. The program, tools, and fixturing will be available for purchase in one complete package. It is a turnkey process where all you have to do is load the block, touch off your tools and hit the go button. The program cuts yoru block automatically while you are working on something else. Average time to machine a block is ten hours. We also have programs available for Dart and World small blocks.

Direct drive motors/ball screws on all 3 axes- X, Y, and Z. The belt connecting the ball screws and aces motors has been eliminated and the motors mount directly on the end of the ball screws through a special zero backlash coupling reducing back lash and improving accuracy/repeatability and reducing noise, especially in rapid feed rates.
New Column Casting. Previous version had a rise to extend the capacity between the spindle taper/nose and table top, the new version has a single casting which increases the Z axis travel so the spindle nose moves further down to the table for small industrial jobs such as making parts. The casting is also a Y shape - upside down - given better rigidity and appearance.
New Control Panel and Electrical Enclosure. The electronic hand wheel has been moved a different position to allow installation of the Digital Run Out Gage which has been useful on the F90 machines. The electrical enclosure has a solid aluminum back plate and spindle amp head sink for better cooling of electronic components.

Circular interpolation is a CNC operation that allows a rotating tool to move in a circular motion. When facing counterbores, the cutting tool spins while the spindle or block moves in a circular motion. The main benefit is that it machines a perfectly flat counterbore surface. One of the problems with cutting counterbores with a fixed cutting insert is that the flatness of the counterbore is determined by the accuracy of the lower face of the cutting insert. This can become a problem when tooling is worn. Circular interpolation eliminates the accuracy of the tool and allows a single point cutting action resulting in perfectly flat surface. When using Rottler circular interpolation to face counterbores, a larger undercut corner radius can also be included in the operation.

This quarter we had an opportunity to work with Dinan Cars to help them reduce labor time spent on creating cam clearance for BMW and Ferrari heads. When installing a larger cam a standard cast head has minimal or no clearance to accept the new radius swing. Typical method for creating cam clearance has been to die grind away material in the areas of the head that interfere with the rotation of the cam. Typical time spent using this method has been up to eight man hours to complete two heads. Writing a simple program for the F68 has reduced the time it takes to create cam clearance down to two automated hours for two heads. Actual manual labor in this case has been reduced from eight hours to twenty minutes (the labor time it takes to set up the job). Not only is this method faster and automated it is cleaner and more precise. See photos below:
