(A) manufacturing process. Process refinement mainly refers to the process as short as possible, the merger of the machining processes without intermediate stocks, production, effectively reducing the impact of low-noise ball bearing performance and proces s factors; the production of clean technology, which is a system of technologies, including the grinding fluid, ultra- semen, cleaning fluid, air, high pressure air, production and environmental technology; automation, processing from the car to the assembly of the whole process of automation, few people or no; scale, such bearing mute ball bearings, must form a large-scale technology, in order to have a global market competitiveness. china bearing company
(B) equipment. High speed grinding electric spindle accuracy, stiffness, life and a variety of testing protective properties of the grinding accuracy and efficiency play a major role; grinder technology, foreign internal grinder usually have a high speed grinding, AC servo control, the feed 0.25μ resolution, automatic simple operation, self-diagnostic functions; ultra-precision technology, mainly in Osaka, Japan Seiki unintentional support of the representatives of the two workers ultra-precision hydraulic centering four workers and the German ladder Lun House bit ultra-precision two ways; online detection technology since the 1980s, Japan s bearing industry initiative measuring machine, automatic feedback control grinding ultra-short-term application is the most common. Our country in this manner constitute autoline applications mature, and currently has about 100. Mainframe technology with the advanced industrial countries, the line is getting easier to gradually reduce or do not take the initiative to measure and outside the machine detection; Centerless cylindrical grinding machine, outside the circle (KOYO, MIKROSA, etc.) commonly used by Rolling the wheel spindle unit, with a high stiffness, high precision, long life, easy handling, the use of reliable and a number of advantages; bed with damping reduction features; feed using high-precision micro servo system, th e stability of the drive AC variable frequency guide wheel adjustment system with online The random measurement of intelligence, the CBN grinding wheel can be automatic on-line, roundness of up to 0.3μm size dispersion of up to 3μm. bearing company
Surface grinder, double-ended foreign (eg, KOYO, Landis Gardner) surface grinder spindle is commonly used high-precision, high-stiffness rolling bearing spindle unit wheel axis systems, mist lubrication. Gardner technology, for example, the company s production system is equipped with more than 90 years of history, grinding bearings, ceramic, glass, rubber, plastic and other materials. Automatic wheel dressing and compensation techniques, wheel grinding head into the given servo motor screw coaxial structure, the grinding wheel to the inside and outside the fast synchronous feed, feed accuracy can r each 0.25μm, the body was placed in two horizontal blocks and balance the device, the balancer has a self-balancing support bar can automatically adjust the pad with two levels into a horizontal plane, so that the machine to a solid support, the balancer focus is to maintain the grinding wheel shaft concentricity to increase the wheel dressing interval, the workpiece feed rotary, reciprocating, throughout and special four forms can use the super abrasive grinding wheel, diamond grinding wheels and CBN grinding, grinding and high precision, good stability, a very long wheel life and convenient operation adjustment abrasives, according to the processing requirements specially formulated combination of agent, structure (ring, button-shaped or links like), so as to achieve the best grinding results, parallel deviation and flatness up to 1μm. bearing manufacturer
