Product information of Ningbo Haigong Group Company

Ningbo Offshore Group has successively developed SCY and WHM series horizontal honing machines, four-axis linkage grinding machines and electrical textile products. Horizontal honing machine and mutual research machine won the Science and Technology Progress Award of Ningbo City, Zhejiang Province and the National New Product Award of 1994. WHM200 precision honing machine and S-QZ60- 1400 automatic hydraulic shearing machine are our main export products. Widely used in aviation, aerospace, automobile, motorcycle, oil pump nozzle, industrial sewing machine, precision mould, air conditioning and refrigeration, hydraulic pneumatic, bearing, brass musical instrument, military industry and other industries for precision machining of small holes.

The main products come from two categories: honing machine products and four-axis mutual grinding machine products.

Classification by honing machine product model:

Semi-automatic horizontal honing machine (SCY60 16)

Semi-automatic single frequency conversion horizontal honing machine (WHM-70 model)

Double-guide single-frequency horizontal honing machine (WHM- 100 model)

Double frequency conversion and double guide rail precision honing machine (WHM-200 model)

WHM- 100A/B double frequency conversion double guide honing machine

HG- 1 precision honing machine

According to the product model classification of four-axis mutual research machine:

Four-axis grinding machine (SCY-60 12) Taking HG- 1 precision honing machine as an example;

1, processing aperture range: φ 30mm ~ φ130mm;

2. Spindle speed: 150 rpm ~ 800 rpm, with frequency converter for speed regulation;

3. Stroke length: 0 ~ 0~ 180mm, stepless;

4. Travel speed: 40 times/min ~ 150 times/min, adjusted by frequency converter;

5. Spindle motor: power 3kW, speed regulation and braking by frequency converter;

6. Stroke motor: the power is 0.75kW, and the frequency converter regulates the speed and brakes;

7. Cooling pump: power 130W, flow rate 25L/min；; ;

8. Filter motor: power 40W；;

9. Total power of power supply: 4kW；;

10, working volume of cooling box: 350L；;

1 1, overall dimensions of main engine (length× width× height):1080mm×1430mm×1360mm;

Overall dimensions of fuel tank (length× width× height):1010mm×1150mm× 745mm;

12. Net weight of machine tool: 920kg (including main engine 765kg, oil tank 155kg, excluding honing oil weight). 1, wide processing range and high efficiency. Especially, the horizontal honing machine on the market can't process parts with a hole diameter of more than 90mm, and its efficiency is higher than any honing machine on the market. It can directly replace twisting, boring and internal grinding, and directly replace expensive large-caliber vertical honing machine.

2. Good stability and long service life. The upper and lower boxes are made of cast iron and are aged; The spindle adopts unloading device to reduce wear and prolong service life; The pulley is checked and processed by dynamic balance; The spindle bearing adopts imported bearing and high-rigidity double-guide linear rolling bearing stroke support.

3. High reliability. Combined with the advantages of honing machine in the market, the whole equipment is rationally optimized, with few faults and high reliability.
