What to pay attention to when buying a heavy-duty cutting lathe
Heavy-duty cutting lathe machines mean heavier cutting, higher rigidity and less vibration. In order to obtain the longest service life and highest accuracy, a lathe with a heavy cast iron base should be selected. Any power less than about 2 hp is not enough for metal cutting.
The chuck of a heavy-duty cutting lathe must be large enough to hold any workpiece in the mind of a mechanic. They need at least a three-jaw, four-jaw chuck and a control panel and tailstock.
Equally important is how many types of spindle bearings are used in heavy-duty cutting lathes and how far apart they are. Cheap spindles with low-quality bearings will only cause problems in one or two years.
A wider bed can provide higher stability and better results in turning operations.
Heavy-duty cutting lathes must have foot brakes to quickly stop the spindle. Geared headstocks with multiple speed ranges help ensure that the mechanic has enough power available. The way of hardening and grinding ensures many years of production use. The job button makes it easier to change gears. Buyers should ensure that the lathe has the correct thread cutting capabilities.
The tool holder of a heavy-duty cutting lathe should be easy to change and adjust the tool. For shaft machining and other longer parts, a stable bracket helps to make the work easier. The dial makes the operation of the lathe easier and less error-prone. If you can afford it, you should buy it.
For those looking for heavy-duty cutting lathes in the market, any machinist will help himself by expanding his search to include tool lathes including heavy-duty lathes. They will most likely save some money by buying a more versatile lathe, and will almost certainly have a higher quality, more durable machine.
