long: 1520mm width: 609mm height: 1200mm
1．Not equidistant dorsal column structure is more scientific and reasonable. It ensures piano durable and guarantees that the piano remains stable under the strain of the strings.
2．V120 is not only in line with the piano industry requirements, but also to protect the product quality and stability by applying CNC five - axis machining bending.
3．The drilling work on the iron plate, the milling of the string reinforcement and the connection between the components of the sound source are completed by the high-tech CNC control equipment. It controls the manufacturing accuracy and controls the quality of the piano.
4．Hailun's piano rarely makes the assembly precision to meet industry standard requirements through the temperature control and humidity of the wood and workshops, Hailun's the unique positioning patented technology, and the CNC processing technology from Japan. So that it controls fundamentally the stability of the piano.
5．The piano keyboard is HAINSWORTH felt from the UK, which has good weatherability, so that the piano can be stable in different environments.
6．Germany imported ABEL string hammer with ultraviolet anti-counterfeiting, which is equipped with German VFG hammer felt and is equipped with VFG core felt imported from Germany, and the treble is longer. So the treble is longer.
7．Hailun piano's ribs and other wood parts are selected from various woods in northeast China. Solid wood string code is conducive to transmission of sound.
8． The bass area of the piano adopts the design of the chord pillow button. The double chord set coordinates the effective chord length of the same set of strings, and the bearing force is even, and the vibration performance is stable.
9. Iron rectangular frame structure is made of high-precision vacuum casting. Its source string is firm and stable, and the hole layout is reasonable. Its European carved cast iron plate technology makes the piano more beautiful.
10.The string axis of V120 is made of 18 layers of maple. And it is stable and firm. The tuning peg of VD1 uses chamfer threading technology so that the tone is smoothly without noise.
11.Automatic friction of the string machine weakens the string stress, and ensures a longer and more stable tone.
12.The key bed with metal frame is firm and stable, and the keys chassis is not easy to deform in a long period of time.
13.VD1 is equipped with a weak sound file that is beautiful and generous. It has rational angle location and no noise in the tap linkage system. The transmission beam of wood structure follows the European tradition design.
14．The red and black bicolor black key, spruce solid white key. The ebony keyboard is not only comfortable, beautiful and natural, but also changes the dynamic and static load of the piano by means of built-in counterweight adjustment.
15. It is equipped with color wooden multi-layer aluminum alloy adjustment file (shrinking stalls) to increase the stability of piano work.
16. VD1 is equipped with a keycap descent control device to protect the player's hands.
17. VD1 has push-button lock. Its structure is exquisite and novel, and it is easy to operate.
18. The RENNER technology from German has been widely adopted by Hailun in action.
19. Its spruce soundboard is a single pentagon unequal thickness ranging from thick sound. It allows beautiful sound and good sound conduction.
