 First of all, we all know that in the process of machining mechanical parts, we will inevitably encounter problems in the process of production. Making lathe parts starts with the selection of raw materials. The size and length of the material are related to the process and time of CNC machining. If the material is too long, it will Increase the processing time, the material is too short to be processed. In the process of processing, every dimension and every step requires the operator to detect in time, digital calipers and micrometers are essential, and the detection accuracy reaches 0.001mm. For production, the operator must be patient and careful. Make sure that every part made is qualified. In other words, the operator does not perform self-inspection in the process of programming and machining mechanical parts, so it is so-so, and problems cannot be found in time. When the sequence is transferred to the quality management side, it is too late to find the problem, and a series of

  About the alternative size of them,  Freeze Contour Dual  have three size, the  Freeze Contour Twins  have 4 size to choose. About the treatment areas, Freeze Contour Twins compared with Freeze Contour have much large areas to treat more areas. So compared with them, Freeze Contour Twins have better results, it can ensure largest treatment areas to be treated. Freeze Contour Twins have deep cup it ensures largest treatment areas, compared Freeze Contour Dual the treatment areas quitely smaller than Freeze Contour Twins. So between them which have better results I recommend you to choose Freeze Contour Twins. In treated result, Freeze Contour Twins have much large areas to treat more areas. It means more of fat cells will be treated. In treated flexibility, Freeze Contour Twins have four sizes for handles.One handle one size,one shape and one area. Freeze Contour Dual has three sizes for handles each handles have three exchangeable tips. Freeze Contour Twins will be more flexibility.

  disadvantages of old rolling mill stands Early and old types rolling mill stands were different from modern mill stand. Usually spherical  roller bearings  were installed onto the roll neck, meeting the production requirements at that time. However, it became outdated with more and more  problems as steel mills have higher demand for rolling mill delivering speed. Disadvantage Shorter bearing working life leading to higher bearing consumption, Lower precision of steel products, More wear on roll neck, More endplay for the rolls UPGRADING YOUR MILL STANDS What  ESG Bearing  can do for you? No  cost for upgrading without changing the rolls and bearing housing Maintaining the production requirements of carrying loads of production requirements Advantage ★  Minimizing the roll run-out with interference fit of bearing inner ring and roll neck ★  Allowing higher radial loads and higher rolling speed ★  Higher precision of steel products ★   Convenient for mounting and dismounting, with sep

  DC-DC Converters  are used in parallel The parallel of DC-DC Converter has two aspects, one is to increase the output power, when two or more DC-DC power modules in parallel, requires the good current-sharing function between the DC-DC power module is good, the current-sharing mode cannot achieve only by parallel output terminal or uniform output voltage. Because DC-DC power module output impedance, temperature drift are different, will make the load unbalanced. This parallel operation requires this function of DC-DC power modules to achieve , such as our  YPD600 series products . The second is to increase the reliability of the power supply system, which we call redundant heat backup, as shown in Figure (Figure 9).The requirement of such parallel is that each  DC-DC power module  can separately provide 100% load current, so there is no requirement of current-sharing in parallel use, both provide current and are heat backup to each other. With a diode separation between two modules,

  1，DC-DC Power Module Thermal Design The DC-DC Power Module heat dissipation is mainly through natural convection, forced air cooling, heat-sink installation methods or several combinations of them. For  DC-DC Converters with  small power below 40W , the natural heat dissipation is mainly considered in the design. In use the installation environment is mainly considered. To make it have the convection space, there is a certain power derating, and detect the case temperature at the actual maximum ambient temperature. For  DC-DC Converters above 40W  or with radiator mounting holes, forced air cooling or radiator installation must be considered. The basic method is to calculate the dissipated power  Pd=Pout / -Pout  of DC-DC Power Module through efficiency η  , calculate the case temperature θ c-a=(Tc-Ta)/Pd  through the maximum shell temperature  T c  and the required working environment temperature  Ta , and select the appropriate heat sink or wind speed according to the calculated he

  Remote control switch function  （ CNT ）  DC-DC Converters Remote control switch refers to the "ON" (allowed), "OFF" (prohibited) operation of the output voltage. The control end is generally called the CNT. The  DC-DC Power Modules  are controlled in two standard ways as follows. 1, Conventional control mode 1) Positive Logical Control The CNT terminal connects directly to the-Vin or at a low voltage level, with the output is OFF; The CNT terminal is suspended or connected at a high voltage level, and the output is ON. 2) Negative logical control The CNT terminal connects directly to the-Vin or at a low voltage level, with the output is ON; The CNT terminal is suspended or connected at a high voltage level, and the output is OFF. 2, Isolation control mode In some special applications, you may have to use the way of isolation control mode. An isolation controlled circuit is recommended for reference only as shown in Figure 14. The photocoupled devices usually choos

  When must  Tecar  be used? * Acceleration of the warming up before physical activity * Maintaining of the athletic preparation * Muscle warming * Preventive physiotherapy * Preparation for massages * Preparation for kinesiotherapy * Muscular cooling down * Passive muscle toning Sport traumatology: carpal tunnel syndrome, impingement syndrome,contractures, bruises, joint dislocations, muscular strains, tendinitis, osteitis pubis, etc. What kind of function does Tecar have? Muscle relaxation The precise and aimed effect of the Targeted Radiofrequency Therapy on the hypertonic muscle fibers causes their immediate relaxation. The effect of myorelaxation is primarily based on vasodilation, which occurs immediately during the therapy responsible for higher supply of nutrients into the tissue. Tissue regeneration and healing The improvement of tissue metabolism is a natural and valuable secondary outcome of the therapy. It leads to faster healing of the traumatized soft tissue and faster re

  The   dental burs   is a consumable tool used by the stomatologist. It is a very small steel needle. The needle consists of a needle and a needle handle. If the dentist's mobile phone is likened to a hand-held drill, the bur is equivalent to the drill bit on the drill. First, Classification by function: 1.  Initial grinding bur : When a large amount of cutting is performed, a bur with a coarser diamond grain size (>150 μm) is generally used. 2.  Fine grinding burs : burs smaller than 40μm are used for fine grinding and polishing of the prepared tooth surface. 3. Short Bing emery bur: It is used for tooth preparation with small mouth opening, especially in the preparation of teeth in the molar area or in the preparation of teeth in the molar area of patients with abnormally thick buccal fat pads. 4.  Long-handled emery bur : preparation of teeth in the gingival 1/3 area with long crowns. 5.  Shoulder bur : The design of this type of bur only has emery on the top of its end, whi

  OSANO's newest multifunctional  Magchair --- pelvic floor machine ,  urinary incontinence treatment machine , uses high-intensity focused electromagnetic technology to induce deep pelvic floor muscle stimulation and restoration of neuromuscular control. This  pelvic floor therapy  is capable of producing supramaximal PFM contractions for a few seconds, which are not related to brain function, but are directly stimulatory contractions of the peripheral nerves in the pelvic floor area, the effect of which is not usually achieved by voluntary muscle action ( such as pelvic floor exercises  ---  Kegel). Core technology: high-intensity focused electromagnetic, the maximum contraction of 11,000 times within 30 minutes. 1. The key to the technology is to concentrate electromagnetic energy and penetrate deeply to stimulate the entire pelvic floor area. 2. Thousands of extra-large muscle contractions of the pelvic floor can occur in a single treatment, which is particularly critical for m
