Cast iron plate measurements described in detail, 史丽娟 to answer your questions

Cast iron measuring plate known as measurement platform. Cast iron plate measurements described in detail: cast iron measuring plate / measuring platform flatness test: measuring the flatness test platform, and the previous standard had not the same concept, no longer blindly pursue the use of cast iron plates measuring point of contact general use can focus on the flatness of the test can be, due to the current measurement of the workpiece and the cast iron plate specifications constantly increasing, so the workpiece measurement platform requirements are also changing, measuring the contact point platform How much processing costs and measurement platform has a great relationship, so that the user is no longer sensible deliberately requires measurement of the contact points of the platform. When 200 × 200-3000 × 6000 (special specifications according to the demand side, drawing production) due to the measurement plate is to avoid damage to the plane, but should often face cleaned of dust or other particles, measurements: measuring plate / measuring platform specifications , should be covered by a wiping cloth on a plate to place the gadget or gauge blocks. Common signs of damage flat surface scratches after use should cover up their face in. Measuring plate placed in a constant temperature and humidity Yee controlled air-conditioned rooms, and its advised to avoid direct sunlight or ventilation; particularly important that there should not be a vertical direction of the temperature difference or temperature gradient causes measurement flat working surface and a bottom surface having different temperatures . Even when the ambient temperature returns due to lattice-shaped structure iron plate frame and ribs, and thinner flat face and will help to measure the thermal conductivity of the flat speed to adapt to the external environment. There will always wear flat after use, the user can detect signs of wear following methods: using a high-grade measuring plate to grind the flat, then study the appearance of the state after grinding; straightness detection using the reference gauge flat in each direction.
