High Precision Heavy Live Center CNC Machine Tool, machine tool parts in machining. The top is mainly composed of a thimble, a clamping device, a shell, a fixed pin, a bearing and a core shaft. Thimble is the top of the inner hole of the center hole or pipe material, on the other end can be top end is a spherical or conical parts, thimble by the clamping device fixed. When the parts are not allowed or can not hit the central hole, the use of the clamping device to clamp the turning. The shell and the core shaft drill with pin hole, removing of the fixed pin pin or, to achieve the top two. Top can also be used for the work of the drilling, casing and hinge hole.
Heavy Duty Precision Live Center Product information:
Precision Live Center Material: Bearing steel GCr15;
Precision LIVE CENTER Hardness: 58-62HRC; High rigidity and durability;
Precision Live Center Precision: <5u, speed up to 12000 rpm;
Precision Live Center Integration of angular contact ball bearings and roller bearings with accurate matching ensures high concentric accuracy.
The sealing ring is dust-proof and water-proof at the front end, which can avoid the influence of coolant on the bearing and prolong its service life.
Deep-cooling treatment: All NC chilled for a long time (-180 C, 20 hours) to make retained austenite precipitate into martensite and nano-carbide particles, improve the hardness, toughness and durability of the chuck, reduce the residual internal stress;
Precision Live Center Thermal aging treatment: Long time thermal aging treatment can effectively remove the residual internal stress during grinding.
