Product Introduction of DRO Heavy Duty Lathe
This DRO Heavy Duty Lathe adopts frequency conversion stepless speed regulation, and the spindle box adopts high and bottom gear manual transmission. High power, high speed, reasonable structure, machining accuracy up to level 6, roundness error no more than 0.01mm, surface roughness no more than Ra1.6um; It is suitable for finishing in medium and small batch machining workshops.
The maximum turning diameter of the bed of this machine tool is 1250mm, which is suitable for turning various rotating surfaces and end surfaces such as cylindrical, conical, and arc surfaces, as well as various metric and inch straight and tapered threads. With appropriate accessories and tools, it can also perform various processing such as drilling, reaming, reaming and tapping.
The bed is an integral box-shaped structure, which is made of high-standard cast iron (HT300) for one-time molding and has been subjected to secondary aging treatment, and has good stability; the guideway span (755mm), with good rigidity and strong vibration resistance; the guideway surface is medium-frequency quenched , And precision grinding by the guide rail grinder, to ensure long life, high precision and good retention.
