金屬零件在機加工后，孔口、邊緣、交叉孔處總會殘留毛刺。傳統人工刮削效率低、良率差；拋丸或噴砂又可能損傷表面。高壓去毛刺清洗機另辟蹊徑——用水，且只用水。

After machining, metal parts will always leave burrs at the holes, edges, and cross holes. Traditional manual scraping has low efficiency and poor yield; Shot blasting or sandblasting may also damage the surface. The high-pressure deburring cleaning machine takes a different approach - using water only.

原理：超音速水射流，瞬間“掰斷”毛刺。 高壓泵將水加壓至20MPa以上，通過特制噴嘴以180-250米/秒的超音速射向毛刺根部。瞬間沖擊力在毛刺根部形成巨大應力，使毛刺折斷而剝落，同時對零件表面進行清洗。這是一種非接觸式加工，避免了拋丸對表面造成的二次凹坑損傷。

Principle: Supersonic water jet instantly breaks off burrs. The high-pressure pump pressurizes the water to above 20MPa and shoots it towards the root of the burr at a supersonic speed of 180-250 meters per second through a specially designed nozzle. The instantaneous impact force creates a huge stress at the root of the burr, causing it to break and peel off, while cleaning the surface of the part. This is a non-contact machining method that avoids secondary pit damage caused by shot blasting on the surface.

壓力選型“對號入座” ：

Pressure selection "in place":

4mm以下的細長交叉孔（鋼件類）：射流壓強20MPa，射速180-200米/秒。

Thin cross holes (steel parts) with a diameter of less than 4mm: jet pressure of 20MPa, firing rate of 180-200 meters per second.

4mm以上的交叉孔或孔口：射流壓強20MPa以上，射速大于250米/秒，可同時完成孔口倒圓角處理。

Cross holes or openings with a diameter of 4mm or more: with a jet pressure of 20MPa or more and a firing rate greater than 250 meters per second, the opening can be rounded at the same time.

過濾系統同樣關鍵。粗過濾（40目/寸以上濾網）+精過濾（精度根據顆粒度選型，從100微米到0.1微米不等），必要時可添加磁性過濾裝置吸附鐵屑。

The filtering system is equally crucial. Coarse filtration (filter screen above 40 mesh/inch)+fine filtration (precision selected according to particle size, ranging from 100 microns to 0.1 microns), and if necessary, magnetic filtration devices can be added to adsorb iron filings.

優勢一句話： 去毛刺+清洗一步完成，不傷基材，尤其適合液壓閥體、發動機缸體、精密閥芯等對表面光潔度要求出色的零件。毛刺去除干凈了，后續裝配、密封、使用壽命才有保障。

Advantage in one sentence: deburring and cleaning can be completed in one step without damaging the substrate, especially suitable for parts with extremely high surface smoothness requirements such as hydraulic valve bodies, engine cylinder bodies, and precision valve cores. After removing the burrs, the subsequent assembly, sealing, and service life can be guaranteed.
