How to get the central hole prickle

1. I'd like to know how your shutter wheel is put in. It's wonderful. The abrasive flow is reliable, but the efficiency is not high,

2. Use the punch first, then use the grinding rod to deburr

3. Unknown_Error

4. Hand massage can be used for treatment. He often rubs his hands against each other, that is, with the thumb of his right hand rubs the pain of his left hand, and then with the thumb of his left hand rubs the pain of his right hand. You can press it when you are free, and it will recover in a few months. You can try this method: select the cactus whose area is slightly larger than the inflammatory damage, remove the burr, and scrape off one side of the epidermis. The side without epidermis was attached to the lesion and fixed with medical tape. Every other day for a new cactus, alone for three times, the lump will automatically disappear
for patients with first visit or mild symptoms, braking physiotherapy or local closed conservative treatment can be used. If the improvement of non-surgical treatment symptoms is not obvious or recurrent, it can be treated by surgery. Surgical treatment does not end with incision of the first sheath of the dorsal carpal tunnel, but it should also check whether there are anatomical variations in the sheath, and if so, remove the rendant part. If there is tendon adhesion, it should be released at the same time
according to the situation you described, it is recommended that you pay attention to the maintenance of your skin. Rece direct ultraviolet rays on the skin. Make it a good habit to take a bath regularly. At the same time, pay attention to eye hygiene, not always too long, so as not to cause eye fatigue
manual deburring, as the most primitive and ancient deburring method, is currently used by most enterprises. This method uses sandpaper, grinding head, file and other tools for deburring operation, and the file also has pneumatic and manual. Manual deburring does not require high indivial technical quality of workers. It is very suitable for some procts with simple structure and small burr. However, it has the disadvantages of high labor cost and low efficiency, and can not remove some complex cross hole burr.

Magnetic polishing machine is to use the force of the magnetic field to guide the grinding material (magnetic needle) to rotate rapidly and grind the workpiece, so as to achieve the grinding effects of efficient deburring, surface polishing, polishing, cleaning, oxide film removal, sintering mark removal, rust removal, etc

● workpiece surface polishing, polishing, smooth

● deburring, flash, batch edge, burr

● removing oxide film

● removing sintering trace, restoring metal color

● cleaning, removing metal chips and slag

● rounding off angle of front edge

● optimizing surface electroplating and welding

● metal surface paint removal

6. Use it first Φ 1, and then expand to the required size

7. In particular, it is difficult to deburring the intersection of threaded holes and holes. It is one of the most effective methods to deburring, such as chamfering in the process of processing, manual chamfering after processing, or wire brush, silicon carbide nylon brush, etc. The small ones are OK, the big ones are easy to break, and the explosion deburring. The effect is good, the efficiency is low, the big flanging is also powerless. And there are not many such devices in the country. I support the opinion of the fourth floor. But the burr turned over to the side of the 1.8 hole,

8. Deburring is very simple, Nuojia Noga edge trimmer can be very good deburring, Dongguan Sicheng mechanical and electrical sales
Israel Noga universal magnetic base, scraper, manual deburring series Noga | Nuojia | base | scraper | trimmer | dial indicator

Burr refers to the removal of tiny metal particles on the surface of the workpiece, which are called burr. They are formed in the process of cutting, grinding, milling and other similar chip processing. In order to improve the quality and service life, it is necessary to deburr all metal precision parts. The surface, sharp corners and edges of the workpiece must have a very high degree of metal cleanliness. If necessary, it should also be suitable for non electroplated and electroplated metals. The traditional deburring process is mechanical process, such as grinding, polishing and other processes with different degrees of automation. The quality of the processed workpiece is often not guaranteed

The proction cost and personnel cost are very high. Using the deburring process of deburring magnetic grinding machine, the workpiece is grinded in the barrel with grinding material for 3-15 minutes. It can remove all the tiny burr of precision parts, make the surface of the workpiece smooth and smooth, and bring unprecedented high quality to users. And it will not affect the precision of the proct. Deburring with deburring magnetic grinding machine is not only environmental protection, but also can save a lot of proction and personnel costs. Magnetic polishing machine suitable for material (stainless steel, zinc aluminum alloy, copper, titanium and other non-ferrous metals) machining, turning parts, stamping, die casting, welding, etc

if your workpiece is iron and not suitable for magnetic abrasive polishing, we can also provide you with abrasive flow deburring and polishing machine. The abrasive flow polishing machine can achieve mirror effect on the inner hole of the mold, which is suitable for deburring and polishing of complex inner hole parts

we are dedicated to deburring and polishing instry for 7 years. Our aim is to rece the manpower of deburring for customers, let machines replace manual work, and realize mechanization, automation and unmanned deburring. We have magnetic polishing machine, magnetic grinding machine, fluid deburring machine, electrolytic deburring machine, centrifugal grinding machine, chemical deburring polishing machine, explosion deburring polishing machine, frozen deburring machine and other deburring and polishing equipment. As long as you encounter the problem of deburring and polishing, as long as you call, we can always give you the best deburring scheme

1 Compared with other polishing equipment such as cloth wheel polishing machine, the magnetic polishing machine can be used for batch polishing of workpieces. After polishing, it can be separated from steel needles in batches by screen, which greatly improves the working efficiency and polishing effect. 3-20 minutes can be polished once.

2. Magnetic polishing machine for hardware, trinkets and other dead angle, inner hole treatment effect is excellent. It can remove the st, burr, improve the surface brightness and remove the surface oxide layer, which is incomparable to other types of polishing equipment

The magnetic polishing machine is easy to operate, one person can operate multiple equipment at the same time, saving cost

The magnetic polishing machine uses polishing liquid and steel needle, plus suitable tap water to polish the workpiece in batches, and the sewage without acid and alkali is easy to be treated
