UL1581-560
Wire and cable heating deformation test deviceI. Overview
This test device complies with the UL5601-2006 wire and cable and cords UL560 and UL2556 7.7 heating deformation test standards.
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.
Gun Drills
GUN DRILLS with its ability to Machine very straight deep holes and hold excellent ï¬nishes, was originally developed for gun barrel manufacturing. Today, this drill is designed for deep hole drilling in virtually any material.
The gundrill requires high-pressure coolant through the tool, keeping the cutting edges lubricated and providing adequate chip evacuation down the flute channel. OPT gun drills product line diameter range is .039" [1.00mm] through 1.500" [38.10mm] as a solid carbide head.
Larger diameter tools are available using a brazed inserted blade design. All gundrills can be made to any speciï¬c length. Lengths over 72" [1828 mm] will have an additional weld joint in the body of the tool.
The gundrill is designed to drill holes from solid material, and can produce bottom hole conï¬gurations, and minimize burr at intersections. The gundrill can achieve precision holes in one pass thus eliminating the need for secondary passes, and is a tool for consistent hole-to-hole reproduction.
Flexible in order quantity:
Samples can be provided before mass production, and MOQ can be discussed accordingly.
