Face Mill's Adjustable Insert Pockets Reduce Axial Runout
Tungaloy is expanding its TFE series of face milling cutters for finishing applications to include bodies with adjustable insert pockets.
Tungaloy is expanding its TFE series of face milling cutters for finishing applications to include bodies with adjustable insert pockets. The cutters are said to help achieve near-zero axial runout for good surface finishing results.
The screw and wedge located beneath each insert pocket are used to axially adjust the insert heights to a tolerance of ±0.065 mm (±0.0026"). This is said to improve surface quality on the workpieces and insure uniform wear progression on all the inserts in the cutter, facilitating insert life management.
The adjustable cutters use existing TFE inserts which are available in a range of grades and geometries for a variety of materials and applications, including the AH120 coated carbide grade for steel and cast iron; AH140 for stainless steel; DS1100 with chipbreakers for nonferrous materials; NS740 cermet grade for steel; uncoated KS05F grade for nonferrous applications; and DX140, a PCD-tipped format serving as a nonferrous, high-parameter solution.
The standard cutter bodies are available in the bore (shell-mill) style only, with outer diameters of 80, 100 and 125 mm (3.15", 4" and 5"). Specials are available upon request.
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.
Reducing cutting fluid use offers the chance for considerable cost savings. Tool life may even improve.
Economic efficiency is an important consideration when choosing tools for challenging metals.
