Acme screw trapezoidal screw is widely used in applications: turret milling machines, gantry milling machines, lathes, EDM, grinding machines, woodworking machinery, printing machinery, glass machinery, transport equipment, medical equipment, winding machine industry, packaging machinery, etc. field; Korea and Taiwan transmission business is strong, Dongguan trapezoidal screw manufacturer, with the development, surveying and mapping, the ability to manufacture all kinds of screw and conditions, production and testing equipment, product performance, reliability and stability. Products have been exported to many countries, the United States, Japan and Europe are the major users. Korea and Taiwan drive in a "people-oriented, scientific management, careful construction, dedicated service" business philosophy, "integrity, efficiency" is the driving culture of Korea and Taiwan, we have a lot of highly qualified technical engineers and perfect technical service team to provide customers all aspects, standardization of services. Korea and Taiwan transmission warmly welcome new and old customers at home and abroad to discuss the guidance. We will, as always, to provide users with high-quality products, competitive prices, satisfactory after-sales service, the rise of national industry struggle together to create a cause. Acme screw workmanship standards acme screw thread requiring precise movement as a key component in the movement, mainly high-quality alloy steel processing, heat treatment process to ensure its excellent mechanical properties, in the manufacturing process, coarse and fine step apart, effective stress components ensure a reasonable distribution of the key processes in a constant temperature processing workshop, a stable temperature, high precision lead screw to ensure that all indicators meet the national standard JB / T 2886-1992 Machine acme screw, nut and technical conditions relating to acceptance criteria. Ball trapezoid accuracy class and acceptance criteria: R logo screw, right-handed screw is generally not marked. 7 Screw - For precise drive, precision screw lathes, exon grinder, surface grinder feed motion and so on. Trapezoidal screw Conversion Table 1, tooth type angle trapezoidal thread is generally α = 30 °, the pitch P is determined by the thread standard, different standards, different pitches; 2, crest clearance ac: when P = 1.5 ~ 5 时, ac = 0.25; P = 6 ~ 12 when 时, ac = 0.5; P = 14 ~ 44 when when ac = 1; 3, external thread large diameter d: the diameter d2 = d-0.5P; small diameter d3 = d-2h3; tooth High h3 = 0.5P + ac; 4, internal thread: large diameter D4 = d + 2ac; the diameter D2 = d2; trails D1 = dP; tooth height H4 = h3; tooth top width f = 0.366P; alveolar bottom width . w = 0.366P-0.563ac has imported CNC lathes, milling machines, lathes, centerless grinding machines, table lathes and other specialized equipment. Professional manufacturing acme screw / square screw / long screw / to cover screw / screw conveyor / roller screw / special screw / worm and all kinds of ancillary and other nuts.
