JINGDA is a precision measuring tool manufacturing company, founded in 1979. We can provide wide range of heavy duty measurement tools, such as cast iron surface plate, granite surface plate, cast iron angle plate, cast iron square block, straight edge, V-block and bench center. Our company has been developed as a heavy machinery manufacturer, we use production equipment such as milling, planing, grinding, drilling and boring equipment to ensure quality of measuring instruments.
The cast iron surface plate made through scraping or grinding, is mainly used for leveling the large-scale equipment. It is rational in design, secure in structure, as well as high in precision. It can realize the splicing of the 3,000mm to 6,000mm plate. Our cast iron calibration plate is widely applied in the machining operation.
This precision angle plate is suited to the parts inspection as well as the clamping in the mechanical processing. It is used to inspect the right angle of the workpiece. When repairing the equipment, it not only can be used to examine the parts perpendicularity, but also used for scribing.
After the long-term natural aging, the granite inspection plate is uniform in structure, and has low coefficient of linear expansion. The internal stress has completely disappeared, which means no deformation will be found. Therefore, our product offers high precision.
The cast iron square block is mainly used to inspect the verticality, parallelism of parts. It can be utilized to support the workpiece for scribing. Generally, it is a cube or cuboid in appearance. We can make the cast iron measuring block of various sizes based on the client’s requirement.
The bench center is chiefly used to inspect the circular runout of the shaft parts and plate-like parts. It is unique in design, elegant in appearance. Additionally, this measuring equipment features high precision, and can be conveniently used.
The straight edge or square is made in accordance with the GB/6318-85 manufacturing standard, and applies the HT250 materials. It adopts the scraping or precise grinding process for its working surface. Aside from the equipment installation, this straight edge and angle ruler is also mainly used for inspecting the straightness and flatness of the working piece.
The machining tools are made of HT250 or HT300. Our company applies new technology, scientific management, and advanced casting technology for manufacturing large casting parts. The advanced processing technologies include resin sand casting, artificial tempering, foam molding, natural or electric shock aging.
The shock mount is suited to support and level the machine tool or other equipment. It is mainly used to withstand the main loading and continuous vibration. This type of metal shock mount mainly includes adjustable type, anti-vibration mount, multi-layer anti-vibration mount, etc.
