FAQ
Q1: What is the notch specimen preparation machine used for?
The notch specimen preparation machine is equipment specially used for preparing notched specimens for impact toughness testing of non-metallic materials. It is used together with Izod impact testing machines and Charpy impact testing machines. It can precisely machine standard V-shaped or U-shaped notches in specimens, ensuring the accuracy and repeatability of impact test data. It is widely used in plastics factories, modification plants, quality inspection laboratories, and third-party testing institutions.
Q2: What standards does it comply with?
It complies with the following domestic and international standards:
· ISO 179-2000 (Charpy impact)
· ISO 180-2001 (Izod impact)
· GB/T 1043-2008 (Charpy impact)
· GB/T 1843-2008 (Izod impact)
The specimen preparation precision meets the requirements of the above standards for notch shape, dimensions, and surface quality.
Q3: How many specimens can be processed at one time? What about efficiency?
It can clamp 20 specimens of 4 mm thickness at one time, and can process more than 60 notches every 10 minutes. The batch specimen preparation efficiency is very high, making it suitable for laboratories and production enterprises with large sample volumes.
Q4: What is the blade life like? How often does the blade need to be replaced?
The blades are made of special imported alloy material, with hardness greater than HRC60 and surface roughness less than Ra0.4. The cutting edges are sharp and wear-resistant.
The blades can be reground repeatedly and have a long service life. Signs that the blade needs regrinding: burrs appear at the bottom of the notch, surface roughness decreases noticeably, and deviation in notch dimensions increases. Blades are consumable parts, so it is recommended to keep spare blades on hand to avoid affecting test progress.
Q5: Is it safe to operate? What protective measures are there?
Safety is ensured in two ways:
1. Emergency stop switch: in an emergency, press the emergency stop and the equipment stops immediately.
2. Automatic shutdown when the cover is opened: if the protective cover is opened while the equipment is running, it will automatically shut down to prevent injury caused by misoperation.
