A dual-contact main axis is usually standard on a machine that USES a cat or a bittorrent interface. Although the double-contact spindles work with all cats or BT holders, there is a significant performance advantage with the BRY pair
Contact the clamping device.
On the main shaft of the machining center, a standard taper taper tool system is designed to meet the fixed taper. The tool controls the taper through a rod mechanism. When a traditional bracket is on the spindle, there is a 3mm gap between the tool support flange and the main axis.
Double touch, including the handle (cone) and the blade flange, is a method to eliminate hilt. The precision machining of the main shaft hole, the taper of the knife and the flange are connected, so that the cone and the surface are seated at the same time, thus producing double or simultaneous contact on both surfaces.
In the main axial plane and radial plane, the contact between the spindle cone and the flange contact is a solid combination. In operation, the holder of double contact cutter has resistance to axial movement, because surface contact prevents the tool frame from being pulled into the spindle at high speed.
In order to realize the double contact between taper and flange, the 1.5mm is added to the main shaft, and the 1.5mm is added to the blade flange. The taper didn’t change.
Adding this material effectively closes the 3mm gap between the spindle surface and the tool holder flange. Eliminating gaps allows these tools
There is a double connection.
The rigid connection between the tool frame and the main shaft becomes crucial as the store continues to increase production speed to the high speed curve.
The advantages of grinding machine with large spindle are:
The best T.I.R.
The increase of stability and tool rigidity increases the quality of surface finish and increases the life span of the spindle
