â—†Material identification: Redwood does not refer to a specific kind of wood, but refers to some wood with purple-red color and hard wood, such as rosewood, rosewood, red sandalwood, etc. can be called mahogany. The mahogany inlaid silver small pieces mainly include rosewood, ebony, wenge, rosewood and rosewood. The rosewood has a blinking shape and is irregularly shaped. People usually call it "crab claw pattern"; the new sandalwood is like a red color in the sauce. The old red sandalwood is oxidized to dark black, the old red sandalwood does not fade, and the new red sandalwood Faded, although the pear trees have similar blinks, they are less, basically arranged in a straight line. The color of the red rosewood is similar to that of red sandalwood. The material is hard and fine. It is usually called “old mahoganyâ€, and the pear wood is scraped with some wood chips. It has obvious sour taste; the rosewood texture is mostly black, wide, the wood grain is thick, and the texture is straight. The texture of the chicken wing wood is beautiful, like water waves floating, and like the golden chicken color feather, the black chicken wing wood is more beautiful and distinct than the yellow chicken wing wood texture, so it is more precious.
â—† Appraisal of the appearance: As the saying goes: "Looking at the image, looking at the art", that is to say, the mahogany crafts must have exquisite craftsmanship and meticulous creativity. There are three main points: First, the skills, including whether the woodworking skills are exquisite and the lacquer skills are perfect; the painter effect is an important aspect of the quality assessment. To make the paint surface even and thin, there is no paint left at the seam, and the post-grinding mill arrives at home, and there is no sticky particles on the paint surface. Second, whether the content of the work has new ideas; the small pieces of good mahogany should have new ideas. The so-called new meaning means that the works must be innovative and changeable. The third is the charm of the work. Exquisite mahogany pieces must have a charm, the so-called charm is a work not only tangible, but also God.
â—†Collection and value identification: The economic value of the mahogany piece itself is composed of its historical value, artistic value and market supply and demand. The influence of the craft level on the price is very large.

High Speed Door Motor And Control Box
Our company have German SEW Motor, Japan Mitsubishi Controller. Our own brand Hofic servo motor and controller. Chinese famous brand SEJ motor and Holip controller.
About our German SEW Motor and Japan Mitsubishi Controller: It is easy to find the ideal energy-efficient motor for your application at SEW. The series has a suitable design in its range for the globally applicable efficiency classes. Select the power and frequency within this motor design and you have already taken care of the most important selection criteria.All other motor options are of course available independently of the efficiency class. A comprehensive braking concept and cost-optimised built-in encoders ultimately complement the motor range. Comprehensive braking concept and combinations i.e. up to three different brake sizes per motor size featured in the range: Cost-optimised built-in encoders integrated into the motor. Motors for efficiency classes IE1 to IE4.Compact design saves space and costs. Future-proof, also as regards environmental protection (standards). Reduction in operating costs when using energy-efficient motors; our energy-efficient motors conform to the efficiency classes.
About servo High Speed Door Servo Control System: Our rolling gate servo control system is suitable for high speed and high usage soft and hard rolling gate. The whole system is in a small and light package, it has high torque and high operating speed, lower noise, high reliability, smooth and soft operating curves, it`s suitable for high speed and usage environment. The rolling curtain can be controlled by pull switch, push button, Bluetooth, ground radar, ground magnetic sensors. Operating Speed: 1M/s; Operating Width: ＜16 ㎡; Daily operating time: ＞2000 time; Rated voltage: 220v; Rated Output: 0.75 KW/1.5KW.
The system can operated via: 1) control box; 2) inching electronic control; 3) continuous automatic operation; 4) emergency stop; 5) single side operation box; 6) time delay; 7) ground radar and/or magnetic sensors. Please refer to Wiring Terminal for eternal connections.
System has fuse/safety wire shutdown switch for three-phase power protection, fuse/safety wire for operating circuit protection, and temperature sensing relay for motor protection.
Stroke Controller utilizes absolute value encoder. Connect the absolute value encoder and reducer via encoder`s axle, and fix the wings on to the reducer, than insert the aviation plug into plug receptacle.
The mounting screw for the control box must inspect regularly to prevent screw been getting loose and falling off. Check the internal and external wirings. Check and change the oil for the redactor on regular basis.
Precision: The system use Full closed-loop servo control and Double Encoder design. This is to ensure long operating life and to prevent overshooting during operating.
Stability: The system utilizes integrated design concept, in order to simplify internal wiring and prevent any function caused by wiring and terminal connections.
High Speed: Motor max speed is 2500 rpm; door max operating speed is 2 m/s.
Smooth: The torque servo system can adjust torque to the load automatically, and its speed curve mode step less speed regulating to ensure a smooth operation.
About SEJ motor and Holip controller: Three-phase asynchronous motor with magnetic brake has broad uses, It is suitable for various mechanical main drive and auxiliary drive, and it is also used for various required rapid stopping and correct positioning. The braking time within 0.2 second. Electric motor is added the DZM series direct current electromagnetic arrester by the basic series(Y series) electric motor.The protection class of electric motor part is IP44,the arrester part is IP23.if be applicable to bad environment can also make the arrester part into IP44,but customer have to put forward a special request while ordering,the manufactory can design a manufacturing exclusively. Its structure diagram is picture 1 and 2,picture 1 is the structure with hand release.Picture 2 is the structure without the hand release.Its operating principle BE, after being to make the retardation coil(6)to connect direct current power supply,because of the function of electromagnetic force,electromagnet(7)attract gag bit(5),and compress spring(24),make arrester disc(2)away from the friction surface of the gag bit(5)and shield(26)(the electrical motor can immediately operate normally).When the power supply cuts off after,the electromagnet(7)loses electromagnet force,the spring(24)releases the gag bit(5)and compress tightly to arrester disc(2),the arrester function,stop(the motor shaft)quickly,make electric motor shop turning to move,for the second time connect power supply will repeat above-mentioned action.
