Deburring and Burnishing Tools for Swiss-Type and Other Lathes
PMTS 2017: Cogsdill Tool Products Inc. will display a variety of deburring and burnishing tools designed for production machining on Swiss-type and other machines.
Cogsdill Tool Products Inc. will display a variety of deburring and burnishing tools designed for production machining on Swiss-type and other machines. On display will be the company’s Micro Roller Burnishing Tool series that includes internal tools for part IDs up to 0.501” in through and bottoming styles. Also on display will be external tools for ODs between 0.054-0.254” in bottoming style. The MRBT tools feature a compact design with short tool projections for use where limited space is available. The tools mount in “gang” toolholders, and they feature a rear adjustment mechanism with 0.0001” incremental adjustment capability. These easy to apply and easy to adjust tools provide the ability to obtain ultra-low surface finishes (as low as 2-4 Ra) in seconds, the company says.
Running rotary milling cutters at the proper speeds and feeds is critical to obtaining long tool life and superior results, and a good place to start is with the manufacturer's recommendations. These formulas and tips provide useful guidelines.
One of the most common methods of tapping in use today on CNC machines is 'rigid tapping' or 'synchronous feed tapping.' A rigid tapping cycle synchronizes the machine spindle rotation and feed to match a specific thread pitch. Since the feed into the hole is synchronized, in theory a solid holder without any tension-compression can be used.
Economic efficiency is an important consideration when choosing tools for challenging metals.
