Helical Milling Tool Now Available in Inch Sizes
The Dormer Pramet shoulder milling range has been expanded with inch cutters, geometries and inserts.
The Dormer Pramet shoulder milling range has been expanded with inch cutters, geometries and inserts, among which is the Helical AD for roughing applications. Offering the ability to cut as deep as 3.150", the cutter is especially suitable for use with the company’s ADMX 16 inserts, supporting medium machining of varied engineering materials including cast iron, stainless steel, aluminum alloys and super alloys.
The clearance between the cutting teeth, combined with internal coolant delivery, enables efficient chip evacuation, according to the company. The axial clamping of inserts on the end teeth is said to increase milling stability. This also helps to minimize noise and vibration which in turn reduces tool wear. The surface treatment of the body is nickel-plated for resistance to corrosion and lower abrasion.
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.
Consider these alternatives when conventional drilling can't do the job.
The right choices in tooling and technique can optimize the thread turning process.
