机加工件非常容易被低估的缺陷，不是尺寸超差，而是交叉孔、油道转角处那圈不到0.1mm的软毛刺。人工倒角看得到外面，看不到内腔；锉刀一过，棱边圆了，孔里却多了一撮金属碎屑。

The most easily underestimated defect in machined parts is not the size deviation, but the soft burrs of less than 0.1mm at the intersection holes and oil passage corners. Artificial chamfering can see the outside, but not the inside; As soon as the file passed, the edges became round, but there was a pinch of metal debris in the hole.

高压去毛刺清洗机干的事很简单：把水加到几十兆帕，通过CNC或机械手带着喷嘴对准毛刺根部扫过去，水箭在微区产生出色大剪切应力，毛刺从根部断掉，同时把切屑和油污一起冲走。

The task of a high-pressure deburring cleaning machine is simple: add water to several tens of megapascals, and use a CNC or robotic arm with a nozzle to aim at the root of the burr and sweep it over. The water arrow generates great shear stress in the micro area, causing the burr to break off from the root while washing away the chips and oil stains together.

但它不是“压力越大越好”：

But it's not 'the greater the pressure, the better':

铝件、铜件：20–30MPa就够，压力过头会把薄壁打变形；

Aluminum and copper parts: 20-30MPa is sufficient, excessive pressure will deform the thin wall;

钢件、铸铁件：可拉到40–60MPa，厚翻边才断得干净；

Steel and cast iron parts: can be pulled up to 40-60MPa, and only with thick flanges can they break cleanly;

交叉孔、盲孔：核心不是压强，是喷角+排液口。水只进不出，毛刺断了也卡在腔里，清洁度照样不合格。

Cross hole and blind hole: The key is not pressure, but spray angle and discharge port. Water only enters but cannot exit, burrs are broken and stuck in the cavity, and the cleanliness is still not up to standard.

深腔件：固定喷嘴够不着的地方，得上多轴联动或转台工装，不然就是“外面锃亮、里面藏渣”。

Deep cavity components: In areas where the fixed nozzle cannot reach, multi axis linkage or turntable fixtures are required, otherwise it will be "shiny on the outside and slag hidden inside".

买设备时别只盯着“多少兆帕”，这三个配置才决定你能不能量产：

When buying equipment, don't just focus on "how many megapascals", these three configurations determine whether you can mass produce:

过滤闭环：粗滤+精滤+沉降，循环水干净，才不会把刚冲掉的颗粒再喷回工件上；

Filter closed loop: coarse filtration+fine filtration+settling, circulating water is clean, so as not to spray the particles that have just been washed away back onto the workpiece;

参数记忆：换型号只调程序不换人，多品种小批量才跑得动；

Parameter memory: When changing models, only adjust the program without changing personnel. Only with multiple varieties and small batches can it run smoothly;

前后工序衔接：高压去毛刺后面一定跟一道低压漂洗和干燥，否则残水把颗粒带回密封面，前功尽弃。

Front and rear process connection: After high-pressure deburring, there must be a low-pressure rinsing and drying process, otherwise residual water will bring the particles back to the sealing surface, and the previous work will be in vain.

冷知识：毛刺这东西，后道怎么清都只是“善后”。刀具寿命、出口转速、倒角量没控好，再贵的高压机也救不回波动的毛刺高度。

Cold knowledge: Burrs are just "aftermath" no matter how clean they are afterwards. The tool life, export speed, and chamfering amount are not well controlled, and even the most expensive high-pressure machine cannot recover the fluctuating burr height.

真正稳的产线，是前端少生毛刺、后端合理清毛刺，中间不过度依赖人工返修。

A truly stable production line is characterized by minimal burrs on the front end, precise deburring on the back end, and no excessive reliance on manual repair in the middle.
