Brake disc machine tools are specifically designed for machining automotive brake discs and other disc-type parts, typically featuring efficient and high-precision machining capabilities.nMachining Dimensions: Different models of brake disc machine tools have varying machining dimensions. For instance, the VTT500S2 model from Shenyang Julang Special Machine Tool Technology Co., Ltd. has a maximum turning diameter of 680mm, a maximum turning diameter of 500mm, and a maximum turning height of 700mm.nTravel Parameters: Taking the VTT500S2 as an example, the X1 and Z1 travels are ±250mm and 500mm, respectively, while the X2 and Z2 travels are 120mm and 100mm, respectively.nSpindle Power: The spindle motor power of the VTT500S2 is 11Kw/25Hz (reducer), with a front bearing inner diameter of 130mm and a spindle end model of A2-8.nTool Post Related: The VTT500S2 is equipped with a double-row tool post, with both the 1st row and 2nd row tool plates having 2-4 positions.nOverall Dimensions: The overall dimensions (length × width × height) of the VTT500S2 are 2340×2550×3100mm, and the machine tool’s net weight is 8000kg.nBed and Other Castings: The bed, column, base, and slide seat usually adopt HT300 gray cast iron material, which has good strength and shock absorption properties. Castings typically undergo aging treatment to relieve stress, ensuring the stability of the machine tool during high-precision cutting operations.nGuideways: The column and slide seat guideways often use high-frequency quenching treatment to increase hardness and wear resistance. The moving surfaces of the guideways are usually plastic-lined to further enhance the stability and accuracy retention of the machine tool during long-term use.nSpindle Bearings: The front spindle bearings generally use the NSK NN30 series double-row short cylindrical roller bearings in combination with 130BAR double-row thrust angular contact ball bearings with a contact angle of 30 degrees, while the rear bearings use the NSK NN30 series double-row short cylindrical roller bearings, giving the entire spindle system characteristics of long life, low temperature rise, and good accuracy retention.
