The retractable center floating reamer handle is used for machining centers

Returnable center floating reamer shank

Machining center processing case

The center returning floating reamer handle can correct the relocation error of the old machining center, improve the machining efficiency and improve the finish of reaming.

Product Name: spiral case

Product material: Cast Iron

Reaming diameter: d14mm

Reaming depth: 27mm

At present, the main problems are: due to the aging of machine tools and equipment, the use of cemented carbide reamer can only reach the speed n = 150 and feed f = 150. If the speed is increased, it will lead to over cutting and larger aperture. FN = 1mm / revolution, the machining finish can only reach RA = 1.6.

It is hoped that the floating reamer handle can be used to trim the repeated positioning accuracy, so as to improve the speed and reduce the feed per revolution FN, so as to improve the finish.

Use the returnable center floating reamer shank sv-fter25-d25 (Hz), the processing parameter speed n = 700 and feed f = 150

Processing results: the hole diameter tested by go no go gauge is qualified, and the finish RA ≤ 0.8

In the later stage, you can test higher speed by replacing the central spring (greater elasticity), and the cleanliness will be better.
