Abstract

本实用新型涉及一种双色复合涂层的钻头，包括钻头，其特征在于：在钻头的刃面及钻头内槽面上涂布有一层氮化钛膜及氮化锆膜，在钻头外侧面和刃背上涂布有一层铁基彩色氧化膜。本实用新型的优点是降低钻头钻孔时的摩擦力，增强钻头的硬度，耐磨、防锈及增加美观。

Description

一种双色复合涂层的钻头
技术领域
本实用新型涉及一种钻头，特别是一种双色复合涂层的钻头。
背景技术
目前在机械加工中，钻头是一种常用的孔加工刀具，现有的普通钻头一般在钻头的表面不做任何的专用处理，在使用过程中容易发生生锈，且在钻深孔时，钻头的刃口和侧面会产生一个较大的摩擦力，在工作中发热磨损及易发生钻头退火，影响钻孔的效率，降低了钻头的使用寿命。
发明内容
本实用新型的目的是解决现有技术中普通钻头由于外表面不作任何的专用处理所存在的上述问题，提供一种双色复合涂层具体要求高硬度耐磨并且降低使用中摩擦系数的钻头。本实用新型设计一种双色复合涂层的钻头，其特征在于：在钻头的刃面、钻头内槽面及棱面上涂布有一层金黄色氮化钛膜及氮化锆膜，在钻头外侧面和刃背棱面上后涂布有一层铁基彩色氧化膜。本实用新型的优点是降低钻头钻孔时的摩擦力，增强钻头的硬度，耐磨、防锈及增加美观。
附图说明
下面结合附图和实施例对本实用新型作详细说明，
附图为本实用新型的结构示意图，
具体实施方式
图中包括钻头1，其特征在于：在钻头1的刃面2、钻头内槽面3及棱边6上涂布有一层氮化钛膜及氮化锆膜4，在钻头1外侧面5和刃背5上涂布有一层铁基彩色氧化膜7。由于氮化钛膜及氮化锆膜4具有高硬度耐磨性，因此涂布有一层氮化钛膜及氮化锆膜4的钻头1的刃面2及钻头内槽面3在钻孔时可以增加加工工件时的耐磨性，而在钻头1外侧面和刃背5上涂布有一层铁基彩色氧化膜7可以大大降低钻头外表面的摩擦系数，提高钻孔的效率，同时又可以防止钻头1的锈蚀及增加美观。
