Double-end grinding machine is a kind of equipment that can grind two end surfaces at the same time. In recent years, with the continuous improvement of the national independent development capability, the market of double-end surface grinding machines is continuously expanding, and the price is also behind the continuous growth. The cost of manufacturing double-end grinding machines is also constantly increasing.
The reason for the increase in the price of double-end grinding machines is not that manufacturers deliberately increase the cost, but that the manufacturing costs in the industry are increasing. Through industry surveys and analysis, we can find the factors for price increase.
1. Price rise is the main factor. Everyone knows that prices rise rapidly. All things are rising, including food, clothing, housing, industrial production, and financial services. In this case, the manufacture of various accessories, accessories, and consumables for the double-end surface grinder adds a lot of cost, which leads to one of the main factors that increase the cost of the double-end grinder.
2. The increase in service expenses is also a considerable sum. Before selling the equipment, Xiangheng Machinery is free of charge as a customer sample. After the trial grinding at the site, the customer can be seen or delivered to the customer. After the sales of equipment, our factory will follow customers throughout and provide free training for our customers, allowing them to benefit as quickly as possible. In the process of using the device, we have responded promptly to any problems and helped our customers solve the problem at the first time. In these service processes, the material costs, labor costs, and time costs required for the test specimen, as well as the cost of travel, labor, and time required for the after-sales service, add up to a considerable number. These service costs also lead to double The cost of the face grinder has increased.
3. The increase in manpower cost and the manpower cost are calculated from Jiangyin City. The minimum wage of employees was about 1500 two years ago, and it is now at a minimum of 3,000 yuan. As wages have doubled, R&D and office workers have not been included. The increase in labor costs has directly led to an increase in the cost of double-end grinders.
The double-end grinding machine is a high-precision equipment. The grinding technology is continuously developing and the technology upgrading is also a trend. Xiangheng Machinery will devote itself to timely informing the customers of new technologies emerging on the market and help them to upgrade according to the needs of different customers. Welcome to negotiate. Cooperation, mutual benefit and win-win situation.
Branch Pipe, mean pipe fittings tee or tee fittings, tees and the like. It used mainly to change the direction of flow, with a branch in the main conduit to the Office. Can diameter size classification. General carbon steel, cast steel, alloy steel, stainless steel, copper, aluminum, plastic, argon Ge Lek, pvc and other materials produced.
Casting Branch Pipe is a three hole, namely an inlet and two outlet; or two inlets, a kind of chemical pipe outlet, there are T-shaped and Y-shaped, with equal diameter nozzle, orifice diameter pipe also, for three identical or different line Survey Office. The main role tee is to change the direction of flow.

Divided by the diameter size
1. Tee takeover ends are the same size;
2. Same size - Reducing tee competent to take over, and over size is smaller than the executive branch pipe over size.
Divided by technology
1. hydroforming
Tee hydroforming is compensated by the axial expansion of the metal material of a branch pipe forming process. The process is the use of special hydraulic machine, the injection of the liquid and the inner diameter equal to the three-way tube, side cylinder synchronous movement of the extruded tube by two horizontal hydraulic presses, tube after extrusion by the smaller size, the inner tube the volume of liquid with the smaller tube and pressure rise, when it reaches the three-way manifold pressure required for the expansion, the metal material in the dual role of the cylinder and the inner tube side fluid pressure and flow along the mold cavity bulge manifold.
Tee hydroforming process can be a shape, high production efficiency; competent and shoulder tee wall thickness were increased.
Due to the larger seamless tee hydroforming process equipment required tonnage currently mainly for the manufacture of standard wall thickness less than DN400 tee. Its application for the molding material is relatively low work hardening tendency of low-carbon steel, low alloy steel, stainless steel, including some non-ferrous materials, such as copper, aluminum, and titanium.
2. thermoforming
Thermoforming tee tee is greater than the diameter of the tube, flattening about to tee diameter size,
Stretching branch site to open a hole; tube by heating, into the forming die, and a tensile load manifold die within a tube; tube is radially compressed under pressure, radial compression during the metal flow direction and forming the manifold branch pipe in a stretched punch. The whole process is by radial compression and stretching process tube manifold portion is shaped. Tee hydraulic bulging difference is that hot tee branch pipe metal tube is carried out by radial motion compensation, it is also known as radial compensation process.
Because after pressing tee by heating the material forming the equipment needed to reduce the tonnage. Hot links to wider adaptability of materials suitable for low-carbon steel, alloy steel, stainless steel material; especially large diameter and wall thickness bias tee, often use this forming process.
