Cold-rolled cold-rolled screw screw features: a saving of raw materials, high efficiency, trapezoidal screw, high strength, high gloss, long trapezoidal screw, high precision and good interchangeability. In particular elongated bar, the effect is particularly remarkable, with cutting screw can not be figurative. Thread are: trapezoidal, triangular, serrated; Metric, English, Anglo-American system and other non-standard thread. Raw materials available A3.45 # steel, stainless steel, precision acme screw, stainless steel iron, copper, seamless pipe and other materials. I provide a domestic ladder screw industry's most comprehensive product range of services. The maximum diameter: 100mm, length limitation, pitch: 0.5--8mm, lead: 0.5-24mm. Can produce single and multi-head and non-standard screw; process a variety of non-standard thread, including the common thread, trapezoidal thread and so on. Acme screw Caution regular grade materials must be round, or easy to form the surface of Burr and other easily damaged crack cutter, knife knurled rapid depletion: processing, must be knurled knife assembly more relaxed in the tank moving , trapezoidal screw manufacturers, and without gap is too large, if the gap is too large, the work hob tilt wheel, get out of the uneven pattern, itself fragile: knurled knife plate as far as possible all closed to prevent the chip, miscellaneous etc. splashing into: Never work knurled knife lubrication and cooling to prevent damage thereto closest carbide blade: first start lathe, make the workpiece rotate, then tighten the screw to prevent static friction is too large, the workpiece slippage: selection manufacturing quality to reduce the number of tool changes knurled knife: regular open quick cover, the cleaning blade slot.
