Multi edge milling cutter, a kind of milling cutter for machining the plane of the workpiece at high speed. The blade cutting edge part has 5 10 blades, each blade length is 0.5 1mm, blade to blade height difference of about 0.2mm, a multi step shape. The blade machining plane, multi blade cutting at the same time, the original knife cutting depth is decomposed into 5 10 small cutting depth, the cutting speed can be increased to 50% 100%, to overcome the existing technology of rough milling cutter for cutting depth is not deep and high speed cutting defects, reduce the the cutting force, reduce the cutting heat, improve processing efficiency. If the cutting fluid is applied, the cutting fluid is easier to reach the bottom of the blade, and it can give full play to the cooling and lubrication. The invention has the advantages of simple structure, easy manufacturing, low price, economical benefits, wide use range, high economic benefit, safety and reliability, and is not easily eliminated.
【技术实现步骤摘要】
多刃铣刀片
本专利技术涉及一种刀具,特别是一种用于粗铣工件平面的多刃铣刀片,属于机械加工刀具
技术介绍
铣床和镗床所使用的铣刀盘上的铣刀片,都是方形直刃形状。因为切削速度和切削深度成反比,所以铣刀片在粗铣工件平面时,因切削深度深,切屑宽,不能高速切削,加工效率较低。因此,极须提供一种切削速度快,加工效率高的铣刀片。
技术实现思路
本专利技术的目的是针对上述现有技术的不足,提供一种快速粗铣工件平面的铣刀片。本专利技术是通过以下技术方案实现的:多刃铣刀片,其特征是,所述刀片切削刃部分有5-10个刀刃,每个刀刃长度为0.5-1mm,刀刃与刀刃高低相差0.2mm左右,呈多台阶形状(见图1)。本专利技术粗加工平面时,多刃同时进行切削,将原来一刀的切削深度分解为5-10个小的切削深度,切削速度可提高50%-100%,克服了现有技术之刀具粗铣平面时因切削深度较深而不能高速切削的缺陷,减小了切削力,降低了切削热,提高了加工效率。如施加切削液,则切削液更易到达刀刃底部,能充分发挥冷却、润滑作用。本专利技术结构简单,制造容易,价格低廉,经济实惠,使用范围广,经济效益高,安全可靠 ...
