This standard specifies the basic requirements for the material and hardness, appearance and surface roughness, accuracy, marking and packaging of involute spline hobs with a pressure angle of 30° and a modulus of 0.5mm to 10mm and a pressure angle of 45° and a modulus of 0.25mm to 2.5mm. This standard applies to hobs manufactured in accordance with GB/T5104-2004 and GB/T5105-2004. Hobs manufactured in accordance with this standard are suitable for machining involute external splines whose dimensions comply with GB/T3478.2 and GB/T3478.4 respectively, and whose basic tooth profiles comply with GB/T3478.1. The hob accuracy is divided into three levels: A, B, and C. GB/T 5103-2004 General Technical Conditions for Involute Spline Hobs GB/T5103-2004 Standard Download Decompression Password: www.bzxz.net

Implementation on August 1, 2004
This standard shall take effect from the month of implementation: Replace B/T5103-1U85% Involute Spline Hob with Technical Conditions 3. The main changes between this standard and R/TF103-1985 are as follows: 1. - The 3.5 modulus in the modulus series is cancelled; - GB/13 is changed. |tt||13 in the material part of the general "high energy high speed tool steel: revised G/5193-1985 mark packaging part: canceled the provisions of the material carbide waste: the elimination of the performance test chapter.
The standard was proposed by the Ten-nation Machinery Industry Federation. This standard is also promoted by the National Standardization Technical Committee, the standard drafting unit: Guigong!

General technical conditions for involute spline hobs
GB/5103—2004
This standard defines the material and hardness, external surface properties, marking and packaging of new involute spline hobs (hereinafter referred to as hobs) with a pressure of a0\, a rotation angle of 0.5mm10m and a force angle of 45, a die of 25ram~2.5mm. This standard applies to the roll cutters selected according to GB/T5104-2004 and GB/T1C5-200-. The roll cutters selected according to this standard are applicable to the workpieces with dimensions in accordance with GB/T378.*, GB/T3476.4, and GB/T3478.1. The basic steps of the roll cutters are in accordance with the involute outer flower specified in GB/T3478.1. The roll cutters are divided into three types: A and BC.
