SC-B6 Diameter : 8mm 600MM/PCS,120PCS/CTN,80CTN/PALLET, 10KG/CTN 2. These are used for ALL kind of WELDING PROCESSES & for ALMOST ALL METALS, for One Side welding. Welding processes such as SMAW, FMAW, GMAW, SAW, CO2, TIG, MIG etc. 4. By using ceramic Weld back up strips, Welding COST is saved approx 50 to 60% whereas welding TIME is saved by 50%. RESULTS are 100% RADIOGRAPHIC WELDING. No Back CHIPPING, No Back GRINDING or Gouging, No PURGING required. 5. Weld back up tape consists various profiles of Non Porous CERAMIC tiles for butt welding, Fillet welding etc. 6. Due to having been backed at high temperature, the blocks have excellent resistance to heat shocks in course of rapid heating or cooling. Under the high temperature of welding, they remain stable without producing molten metal drops and in the same time a good back bead is formed. 7. Ceramic materials have the fine property of acid and alkali resistively. Therefore, in process of steel pieces welding, no deformation and no physical or chemical reactions occur.

The induction hardening process is a very important way in the manufacturing process of heat treatment of mechanical parts. In order to improve the hardness of metal's surface, not only should the surface layer depth of the workpiece reach the industrial design standard, but the heat treatment production plants are also needed to introduce the hardening process in the production. Functioning as an effective tool to implement the induction hardening process of steel, the induction hardening machine occupies an irreplaceable position in many heating methods, especially in the control of layer depth and temperature control. As a mature induction hardening machine manufacturer, JKZ sells 1- 10KHZ medium frequency induction furnaces, 15-30KHZ ultrasonic frequency induction heaters, 30-60KHZ high-frequency induction heating machines, and 50- 120KHZ super high-frequency small induction heating machines of high quality. These induction hardening machines hold the power range from 7.5KW to 600KW, which can process workpieces with a diameter up to 2000mm and hardening depth from 1 to 20mm. Moreover, capable of working together with CNC/PLC hardening machine scanner system, JKZ's Induction heating equipment can also accurately control the induction heating coil moving speed, workpiece rotation speed, power output percentage, layer depth, and quenching liquid spray time. Thus, if you are still looking for a tool to conduct effective application of induction surface hardening, our industrial heating unit can then perfectly meet all your needs for the hardening and heating processes. JKZ is a professional induction hardening machine manufacturers, we provide induction heating machine china, induction heating power and etc. Want to know more? Please contact us.

A Telecentric lens, is a kind of lens that the chief rays are parallel to the optical axis. There are three kinds of telecentric lens, that is object space telecentric lens, image space telecentric lens, and bi-telecentric lens. Telecentric lens is always the core business of Canrill Lens. After continuous research and development for 11 years, Canrill has successfully developed 1700+ kinds of lenses, and the number is still increasing, to meet the diverse and growing applications. Advantages Of Canrill Telecentric Lens High telecentricity and little-to-no distortion for accurate measurements Good consistency for better telecentric imaging Extensive range of machine vision telecentric lens covering sensor size from 4.8mm to 82mm and supporting object FOV from 0.7mm to 390mm. Considerable inventory offers the quickest leading time in industry Quick customization service,break the customization record by producing a new lens within 12 days from design to finished product World-famous brands endorsement, like Apple, Samsung, Huawei, Han's Laser, Foxconn, etc. Telecentric Lens Tutorial What is a Telecentric Lens? The telecentric lens is mainly designed to correct traditional industrial lens parallax. Within a certain range, a telecentric lens for machine vision can make the image magnification of the image does not change. Currently, due to its unique parallel optical path design, the telecentric lens has been widely favored by machine vision applications that are highly required for lens distortion. What's The Difference Between Resolution & Mtf30 For The Telecentric Lens? Resolution and MTF have a different definition method. Resolution formula is R=0.61*λ/NA. R is object resolution and λ is wavelength, which is usually 0.55um. NA is the numerical aperture of the object side of the lens. For example, XF-MT1X65D, the NA is 0.045, thus the resolution is 0.61*0.55/0.045≈7.45um. ( the resolution in our product list and drawings is 7.33um, is because decimal point numbers ) Therefore the corresponding line pairs should be 1000/(7.33*2)=68Lp/mm. MTF is Contrast of output image/Contrast of input image. Since the input image is always larger than the output image, therefore the MTF value is always from 0-1. MTF30 means the line pairs when the image MTF value is 0.3. So to calculate the image side resolution, the formula is 1/MTF30/2. For example, XF-MT1X65D, the MTF30 is 90lp/mm, then the resolution is 1/90/2=5.56um. What Is The Resolution Of Telecentric Lens? Resolution is the ability to resolve details in the object. It describes the thinnest line that the human eye can distinguish. Normally, the resolution for machine vision telecentric lens is as below: R=0.6*λ/NA; λ is the wavelength of the light(normally λ is 550nm); NA is the numerical aperture of the lens. How To Improve The Deep Of Field (dof) Of A Telecentric Lens? The DOF of a telecentric lens can be changed by adjusting its aperature. When the aperature gets bigger, the DOF becomes smaller. When the aperature gets smaller, the DOF will increase. What's The Advantage Of Telecentric Lens System? Telecentric Lens can eliminate the parallax error characteristic by having a constant, non-angular field of view. Its magnification and field of view do not change at any distance from the object. Telecentric Lens has a very low level of distortion, which makes the telecentric lens an excellent choice for metrology applications Telecentric Lens can have a larger depth of field, which is beneficial in maintaining a very good image contrast even when looking at very thick objects Canrill is a professional optical lens manufacturer, we provide image space telecentric lens, telecentric lens image, machine vision illuminator, illuminator machine and etc. Want to know how to make a telecentric lens?
