Product Description:

MMW-1A microcomputer controlled vertical universal friction and abrasion testing machine

Product description

1. This machine has the friction forms of sliding, rolling or sliding-rolling compound motion under some contact pressures; it has a stepless speed regulating system, and under low speed or high speed conditions, it can evaluate the friction and wear properties of lubricants, metal, plastics, coating, rubber, ceramics and other materials, such as low-speed pin-on-disk (having large disk and small disk, single needle and three-needle) friction function, four-ball long-term antiwear property and four-ball rolling contact fatigue and thrust washer friction performance tests. It can replace American FALEX6 multi-functional testing machine, and it is a testing machine generally adopted by many units engaging in tribology researches, mainly used for tribology performance tests of materials and coating. The four-ball friction pair is used to test the antiwear property of lubricating oil, meeting the requirements of SH/T 0189-1992 “Method for Determining Antiwear Property of Lubricating Oil (Four-ball Machine Method)”, and it has been widely applied to the development of antiwear hydraulic oil products.
2. This machine is widely applied to various fields of technologies of tribology, petrochemical, machinery, energy, metallurgy, aerospace, various junior colleges and research institutes (institutions).

Q:Infiniti I30 Car Alarm?
Try removing the 15 amp fuse in cavity number 56 first and then start the vehicle and make sure that everything is working. If that will not work the you will need to have the vehicles computer scanned because if you disconnect the module the vehicle will not start.
Q:I am going to make a cheesecake and I keep reading that I should use a water bath when baking.?
Flavored tobacco!?!?!?!?!.HA HA HA HA HA HA HA HA HA HA HA HA HA .
Q:what camshaft should i run?
There are a lot of options here Do you have a reliable speed shop near ? Just saying you want a cam is a good start but matching the correct one to what you want requires a bit of looking If no speed shop , get tool free number for Jegs and talk to one of their techs He will ask you a lot of questions , but at least you will get right one Be sure and get complete kit You can change the springs with heads in truck .

No radiation buddy as you say that the plate shop plate warehouse do not have to die,
Q:Shelf life of stainless steel electrode
There should be some
Q:How to distinguish sanlux rubber belt quality
1 the cause of the deviation of the conveyer belt is the basic reason of the deviation of the conveyer belt, which is caused by the unbalance of the transverse force during the running of the belt. The main reasons are as follows: 11 installation quality 1) rack and roller are not adjusted straight.2) the roller axis is not perpendicular to the center line of the conveyor belt.3) the frame and the ground connection strength is not enough, the frame is unstable.4) the material and the baffle of the guide trough and the discharging trough are improperly installed and the force is uneven.12 conveyor belt quality 1) conveyor belt joint and central line is not straight.2) conveyor belt with a S shape.13 load quality, loading point is not in the center of conveyor belt.14, maintenance quality, drum cleaning is not clean, sticky coal, material, drum tilt, deformation and so on.2 conveyor belt deviation treatment, conveyor belt deviation many factors, at the same time, because of the belt conveyor type is different, its correction method is not the same. The deviation phenomenon should be analyzed carefully and corresponding measures should be taken.
Q:How to hit the sink hole of the pincers with two screws.
There are two types of options for processing a processing center: One. Drill holes, drill holes, reamer drills, reamer, etc. 2. Milling hole, the use of two or 90 ° right-angle milling cutter milling machining cutter: For small holes such as 30mm in diameter, you can use a double-edged milling cutter for processing. A small blind hole can also be used for a two-blade milling cutter. Small waist type hole, the most reasonable with two-edge milling cutter, drill down to depth first, and then cross the knife. (the large waist type hole will be drilled with a bit and then used to cut the hole to the waist.) Using the 90 ° Angle cutter will have to use milling spiral interpolation, the premise is tool must be smaller than the pore size, all kinds of macroporous, sink holes, waist type hole, ellipse, etc this method processing; There are many other special ways to process the outside of a CNC machine. For example, the perforation of the barrel of the gun, the forming of the shaft of the barrel in the barrel of the barrel, the forming hole, the grinding hole, the rolling hole, the honing hole, Micro-hole processing of the laser threshold, a type of non-circular hole machining based on electromagnetic drive, etc.
Q:What materials do you have instead of silica powder?
The best guide light transmission rate can reach 90%, and the fog is very high, is very white. These products are generally large manufacturers in the market to sign. You have to find an acquaintance to buy it.

(2). The fan system fan selection and preparation of mud wants appropriate. The main ingredients are soil and sand. Generally speaking, the clay content of fan is more, the core contains more sand, and the particle is coarser. And in the two, also mixed with vegetable material, such as grass sawdust, to reduce shrinkage, and conducive to breathability. Soil preparation of van must be extremely careful, after drying, crushing, sieving, mixing, and add the appropriate water, the hard and soft mud into moderate, after repeated rubbing, beating, and after a long time of infiltration, make qualitative. So do the mud in turn van Shicai handy. Turning from the mold to the technical model is very strong, and it is the central link of the block casting technology. For more simple solid objects like knife, Gorbachev, arrowheads, only the model can turn two van, the van called two fan. The container for making hollow containers is much more complicated, and Jane's is as follows: 1. before turning over the fan, it is first necessary to decide where the outer fan should be divided into several pieces and where they should be divided. 2., the method of turning out the outer fan is to use the clay mold to pile up on the mold, and then press hard.
