The diameter of the upper end of the pressure bar: Φ19mm
The diameter of the lower end of the pressure bar: Φ9.5mm
Pressure bar total weight: 250g
Station: 3 groups
Weight: 1, 2, 2, 5, 10, 10, 20, 20, 50, 100, 100, 200g each 3 sets (weight according to customer requirements)
Second, the operating instructions
1. Take appropriate samples and make according to the relevant test requirements.
2. Use a static weight dial gauge to measure the thickness of the sample before the test and record.
3. Place the test device in the aging test chamber and place the weight on the weight plate.
4. Set the temperature and time of the aging tank to the required values ​​of the corresponding standards. Open the meter after the temperature is reached
The switch starts timing.
5. After the time is reached, the sample is taken out, and the thickness value after aging is tested with a static weight dial gauge and recorded.
6. Calculate the deformation rate of the sample as follows and judge according to the relevant standards.
PCD Milling Cutter: Polycrystalline Diamond (PCD) tool is a tool made by welding a PCD composite sheet to a carbide or steel body. Since the PCD composite sheet combines the high hardness, wear resistance, low friction coefficient and strength of the single crystal diamond with the high bending strength of the tungsten carbide cemented carbide, the tungsten carbide hard alloy layer of the composite sheet provides the diamond layer. Mechanical support increases its bending strength, while the hard alloy layer is easy to weld, making it easy to make finished tools. Compared with other tool materials, polycrystalline diamond has the following characteristics: 1 extremely high hardness and wear resistance; 2 high thermal conductivity and low thermal expansion coefficient, fast heat dissipation during cutting, low cutting temperature, small thermal deformation; 3 low friction coefficient Can reduce the surface roughness of the machined surface. When processing aluminum alloy with PCD tool, the hardness of the diamond is high, the surface and metal affinity is small, and the rake face of the tool is polished into a mirror surface, which is not easy to produce built-up edge, and the dimensional stability and surface quality are good. Using PCD tools to process aluminum alloy parts of various specifications, the tool life can reach several thousand to tens of thousands, especially suitable for mass production of automobile and motorcycle parts. PCD tools are also widely used in high-speed machining of other non-ferrous metals and non-metallic materials, and are widely used in automotive, aerospace, electronics and wood processing.
FEATURE:
1.Hardness PCD blanks more than 5000HV.
2. PCD Stone Milling cutters is maily used for High efficiency milling and depth character engraving on underside, grooving areas with good surface Roughness.
3.Top quality as world leading manufactuers, high abrasive resistance and with long service life.
