There's a high-tech accessory in the ballpoint pen, you know?

That's the smallest ballpoint pen, the little metal ball.

How hard is it to make a ballpoint pen? There are only three countries in the world that can make it.

When I was a child, in the 1980s, the most commonly used pen was ballpoint pen. Even today, many people are still used to using ballpoint pen. Ballpoint pen in the market price is very low, so naturally no one will care about the structure of ballpoint pen! But you know what? It is such a humble ballpoint pen, but its manufacture is very difficult, the most difficult part is its ballpoint pen head!

How hard is the ball point pen? At present, only Japan, Switzerland and China can make it! Of course, in the past, China's ballpoint pen heads were all imported.

It's no surprise that Switzerland can make a ballpoint pen head, because Switzerland's machinery manufacturing has always been very precise! World famous Swiss watch! Switzerland is a global leader in micro technology.

Let's analyze the structure of ballpoint pen.

The ball point pen is composed of the ball point and the ball seat. The oil ball point pen is made of brass, steel or tungsten carbide, while the water ball point pen is made of stainless steel, hard alloy or aluminum oxide!

What kind of ballpoint pen is qualified? Under the same angle, the ball point pen head must write continuously for 800 meters without broken line, and these ball point pen heads are qualified.

It takes 20 processes to make a ballpoint pen head in Switzerland, and the error between the groove and the ball must be kept at about 3 microns, which can be compared with our hair! In order to maintain such a small gap, professional precision equipment is indispensable!

Nowadays, China can also make ballpoint pen heads, but their precision is still a little behind that of Switzerland! Therefore, some famous brand ballpoint pens are from Switzerland.

"Manufacturing industry is a very basic element, indicating the development level of productivity in a country or region. A small ball point pen core tells us that technology is the first productivity. When gmtlight manufactures and assembles products, it will also encounter many problems. Some ideas and product innovations have to be abandoned because of technical problems. "

圆珠笔里有个配件是高科技，你知道吗？

那就是那个最小最小的圆珠笔头，那个小小的金属球。

圆珠笔头到底有多难造？全世界只有三个国家能造。

笔者在小时候，也就是上个世纪八十年代，最常用的笔便是圆珠笔了，即便今天许多人还是习惯使用圆珠笔。圆珠笔在市场上的价格很低，所以自然也就没有人会在意圆珠笔的构造！可是你们知道吗？就是这么一支不起眼的圆珠笔，其制造却是非常难的，最难制造的部位便是其圆珠笔头！

圆珠笔头到底有多难造吗？目前只有日本、瑞士和中国可以造！当然以前中国的圆珠笔头都是依赖进口。

瑞士能够制造出圆珠笔头，一般人不觉得意外，因为瑞士的机械制造一直都是非常精密的！世界闻名的瑞士手表！瑞士在微型技术方面全球是领先的。

我们来分析一下圆珠笔的构造。

圆珠笔头是由笔尖上的那个小球珠和球座体两部分组成的，其中油性的圆珠笔头小球珠是由黄铜、钢或者碳化钨制成的，而水性圆珠笔头的小球珠是由不锈钢以及硬质合金或者氧化铝制成的！

什么样的圆珠笔是合格的？在同一个角度下，圆珠笔头必须连续不断的书写800米并且不出现断线，这些圆珠笔头才算合格。

瑞士制造一个圆珠笔头需要经过20道工序，而且沟槽和滚珠之间的误差必须保持在3微米左右，这种误差可以与我们的头发丝相比拟了！要想保持这么微小的差距，专业精密的器械是不可少的了！

如今，中国也能制造出圆珠笔头，但是其精密程度与瑞士相比还是有些差距的！所以，一些著名品牌的圆珠笔头，还是来自于瑞士。

“制造业是个很基础的元素，标志着一个国家或地区生产力的发展程度。一个小小的圆珠笔芯告诉我们，科技是第一生产力。gmtlight在制造和组装产品的时候，也会遇到很多难题。有些想法和产品创新因为技术的问题，不得不放弃。”牛先生，gmtlight。
