Gear hob characteristics 齿轮滚刀特性

Gear hobs according to:齿轮滚刀分类齿轮滚刀分类，，按如下:•Structures 结构

•Types of gearing to be manufactured 被加工齿轮的类型

•Quality of the gearing or machining stage 被加工齿轮的精度或加工工序•

Surface treatment 表面处理

•Structures:按结构分:

•Solid type gear hobs 整体齿轮滚刀

precision tooth hobs, roughing hobs 精滚刀, 粗滚刀

Cutting materials: High-speed steel (conventional, PM), carbide, Speedcore 刀具材料: 高速钢(传统HSS, 粉末), 硬质合金, 速切王•Multi-part gear hobs 装配式滚刀

ICI Hobs, Gear hobs with soldered carbide inserts

or carbide strips 刀片滚刀, 镶刀片或刀条的硬质合金滚刀

Gear hob characteristics 齿轮滚刀特性

Quality of the gearing or machining stage:按被加工齿轮精度等级分:•Gear hobs for roughing Requirements:High chip removal rate,

different quality requirements depending on the following machining process

(honing, shaving, grinding, skive hobbing).

•粗加工齿轮滚刀•要求:高的切屑去除率,

根据后序加工工艺，有不同的质量要求（如珩齿、剃齿、磨齿、刮削）

•Gear hobs for finishing

Requirements: Defined precision (e.g. Q6).•精加工齿轮滚刀

要求: 已知的齿轮精度(例如：Q6).

•Surface treatment:按表面处理方法分:

•Coatings 涂层

Use of gear hobs at different machining stages 齿轮滚刀在不同的加工工序中的用途

Hobbing 滚齿Shaving 剃齿

Rough milled with gear hob 齿轮滚刀作粗加工用Heat treatment 热处理(annealing) (退火)

Heat treatment (hardening, tempering)

热处理(淬火, 回火)

Grinding 磨齿

Toothing finish milled or rough milled for grinding 精滚齿或磨齿前的半精滚齿

Skiving 刮削
