1. What is a milling cutter arbor?

Generally, "milling cutter" refers to a vertical milling cutter used for machining on a milling machine, while "arbor" refers to the holder or fixture installed on the milling cutter shank.

Milling cutter arbors and milling cutters are used together. Today, let's learn about the models and specifications of milling cutter arbors. As a technology-driven enterprise deeply engaged in the field of cemented carbide cutting tools

We know that: Even the most powerful blades require perfectly matched shanks to unleash their 100% potential 。

The shank acts as the machine tool and blade's " neural center ” ", and its rigidity, precision, and stability directly determine the machining efficiency and surface quality.

To this end, we select the world's top shank solutions to help you build " cemented carbide blades + high-precision arbors ” A golden combination, boosting cutting efficiency!

2. Arbor types and common models

BT Arbor (Japanese standard): Different arbor sizes match different machine tools.

CAT Arbor (American standard, also called V-Flange ):

HSK Arbor (German high-speed arbor): Suitable for high-speed machining, with double-sided contact on the tapered and end faces, providing greater rigidity. + 3.

How to choose a milling cutter arbor model? Mainly consider processing needs: rough machining

heavy cutting: select an arbor with a larger taper (such as / series), high-speed fine machining: prioritize using BT arbor. HSK Arbor compatible tool types

4、BT/CAT/HSK These arbors can be used with milling cutters, cemented carbide drills, and other blades. For example,

series can all be adapted for use on these arbors. MS-2E If you need more specific blade recommendations, please provide the following information:

Processing material (steel

cast iron / aluminum alloy / titanium alloy) / Processing type (rough machining

fine machining) / Tool type (face milling cutter, end mill, drill, etc.)

5. Why must cemented carbide blades be matched with professional arbors?

Rigidity transmission

: Ordinary arbors are prone to micro-vibrations during high-speed machining, causing cemented carbide blades to chip, while high-precision arbors can improve system rigidity ，ensuring 50% WC blades withstand the limit cutting parameters. Thermal shrinkage deformation control

: Thermal mounting arbors use 400℃ uniform heating to achieve blade molecular-level bonding with the arbor, with runout accuracy - ≤3μm ，avoiding abnormal wear of cemented carbide blades due to clamping misalignment. Dynamic balance guarantee

Grade dynamic balance arbors can increase the spindle speed to ：G2.5 20,000rpm or more, especially suitable for superhard blade machining of quenched steel and titanium alloys. CBN/PCD超硬刀片加工淬火钢、钛合金等材料。
