This technical information section is provided as a guideline to assist you in the safe and proper use of this new product. These guidelines should not be considered a complete guide but merely a starting point for successful implementation. It cannot be a complete guide because of the variety of machines, machining and programming techniques and component parts that we work with in our individual shops. For this reason, we encourage you to take a careful look at the way you integrate this technology into your manufacturing business.
Swiss style screw machines that have live tooling capability were not designed to accomodate grinding processes. The live tooling in these machines was designed to drive small diameter drills and endmills. The horsepower that is available to drive these small diameter tools is perfectly adequate and generally perform without issue. However, grinding processes require
more horsepower than drilling and milling operations. Also, larger diameter cutting tools, like the grinding wheels that we offer, require more horsepower to drive. It is for this reason that you must be very conscious of the feedrate and volume of material that you ask the grinding wheel to remove. Therefore, consideration must be given to several things, like live tool horsepower, diameter of stock, depth of cut and feedrate. The grinding wheel should always be run at maximum live tool RPM.
The horsepower and RPM constraints of the machine force us to be very conscious of how we use this tool. However, the tool can be very effective when used correctly. Increased surface finish, reduced cycle time and a burr free part are the result. In the column to the right is a list of general guidelines:
