1. Core characteristics and working principles

 

1. Analysis of structural parameters

12 mm diameter working head: suitable for medium-area polishing and cutting operations, with a wider coverage than small-diameter files;

25 mm working part length: It can be operated deep into grooves, narrow slits and other positions to avoid interference from the handle;

6mm shank: Suitable for most high-speed rotating tools (such as electric mills and pneumatic polishers), with strong versatility.

 

2. working principle

Through high-speed rotation (usually combined with electric grinding equipment, the speed can reach 10,000 - 30,000 revolutions/minute), the cutting edge on the working head (such as tungsten carbide, diamond and other materials) is used to grind, mill or polish the surface of the workpiece to achieve precise processing.

 

2. Specific uses

 

1. Metal processing field

Deburring and chamfering:

Deburring the edges and holes of metal parts (such as steel plates, aluminum alloy profiles, castings) to eliminate sharp edges and corners;

Machining 45 ° chamfers on the right-angled edges of mechanical parts to improve assembly safety (such as gears, flanges).

 

Surface finishing and grooving:

Trim the metal welds after welding (such as automobile chassis welds, pipe welds), remove weld bumps and weld slag, and make the surface smooth;

Mill shallow grooves on metal plates (such as wiring grooves on the metal shell of a circuit board, guide grooves on the parting surface of a mold).

 

Mold and precision parts processing:

Carefully polish the cavities of injection molds and stamping molds, and correct the size tolerances (such as mold corners, groove radians);

Machining deformed structures of precision parts (such as curved surfaces of medical device parts, weight-reducing grooves of aerospace parts).

 

2. Wood and plastic processing

Wood carving and reshaping:

Carving patterns and grooves on solid wood furniture and wood carving handicrafts (such as the pleats of wood carvings and the tooth grooves of wooden combs);

Trim irregular edges of wooden workpieces (such as preliminary shaping of root carving blanks).

 

Edging and opening of plastic parts:

Trim the rough edges of injection molded plastic parts (such as toy casings, electrical panels);

Reaming or machining special-shaped holes in the plastic plate (such as t* ventilation holes and installation holes during model making).

 

3. Stone and ceramic processing

Stone surface treatment:

Round the edges and matte the surface of marble and granite plates (such as polishing the edge of the table and t* the details of tombstone inscriptions);

Carve patterns and characters on small stone handicrafts (such as seals, stone carvings).

 

Grinding of ceramic parts:

Trim the edges of ceramic sanitary products (such as washbasins, ceramic tiles), or machine shallow grooves in ceramics (such as decorative lines for ceramic art decorations).

 

4. Automobile and machinery maintenance

Parts repair:

Polish the sealing surfaces of automobile engine blocks and cylinder heads to eliminate scratches or deformations;

Repair worn surfaces of mechanical parts (such as minor damage to gear tooth surfaces, shaft parts).

 

Modification operation:

In car modification, exhaust pipes and body enclosures are cut and trimmed, or mounting holes are machined in metal bumpers.

 

 

3. Precautions for use (optimization of safety and efficiency)

Equipment matching and installation

Ensure that the speed of the electric mill or pneumatic tool is suitable for the rotary file (too high speed may cause overheating of the cutting), and tighten the handle after being inserted into the tool chuck to avoid falling off.

 

operation specifications

Wear goggles and dust masks (when processing metal/stone) to prevent debris from splashing;

During processing, keep the tool and the workpiece surface at an angle of 15°-30° to avoid sticking caused by vertical force, and move at a uniform speed to ensure surface flatness.

 

Cooling and maintenance

Cutting fluid can be used to cool metal during high-speed cutting to prevent overheating and annealing of the working head;

Regularly clean up debris on the working head (especially fiber/slag remaining after processing wood and plastic) to avoid clogging the cutting edge.

 

4. Comparative advantages compared with other tools

Compared with manual files: The efficiency of high-speed rotating files is more than 10 times higher, and it can process complex curved surfaces and narrow spaces (such as chamfering of internal holes), which is difficult to achieve by manual files;

 

Comparative milling cutter: suitable for small-batch, high-precision grinding operations, with lower equipment cost and strong portability (such as handheld electric mills used with), especially suitable for on-site maintenance or DIY scenarios.
