What should we pay attention to when buying a heavy lathe?
Heavy machine tools mean heavier cutting, higher rigidity and less vibration. Lathes with heavy cast iron bases are chosen for maximum service life and accuracy. Anything less than about 2 HP is insufficient for metal cutting.
What should we pay attention to when buying a heavy lathe?
1. Chuck must be large enough to hold any workpiece in the machinist's mind. They need at least a three - and four-claw chuck as well as a control panel and tailstock.
2. Equally important is how many types of spindle bearings are used and how far apart they are. Cheap spindles with low quality bearings only cause problems after a year or two.
3. The wider bed provides greater stability and better results in turning operations.
4. Foot brakes are necessary to stop the spindle quickly. A geared headstock with a wide range of speeds helps ensure that the mechanic has enough power available. Hardened and ground in a manner that ensures years of production use. The job button makes shifting gears easier. The buyer shall ensure that the lathe has the correct thread cutting capability.
5. The tool rest should be easy to change and adjust the tool. For shaft machining and other longer parts, a stable stand helps make work easier. Dials make lathe operation easier and less error-prone and should be purchased if you can afford them.
For those in the market for heavy duty lathes, any mechanic will help himself by expanding his search to include tool lathes that include heavy duty lathes. They will probably save some money by buying more versatile lathes, and will almost certainly have higher-quality, more durable machines.
