  • Are the PRB's meant for aluminum?
    It can, but will leave some scratches so they can use some protection films or order their own custom made Nylon dies.
  • Does PRB's come with a set of universal dies?
    PRB's comes on set of universal dies, which can do all the jobs except the round tubes and pipes.
  • What die will I need to bend 1 1/2" tube on a PRB?
    You will need to order 1-1/2" tube die for , one size die set only works for one size of tube.
  • What die will I need to bend 1" pipe on a PRB?
    You will need to order 1" pipe die , one size die set only works for one size of pipe.
  • Are tube and pipe different sizes?
    Yes, pipe OD is larger than tube OD, check the chart of pipes & tubes. Outside Diameter (OD): The outside diameter (OD) is the distance across the extreme outside dimensions of a tube or pipe. Inside Diameter (ID): The inside diameter (ID) is the longest distance across the inside dimensions of a tube or pipe. Wall Thickness: Wall thickness is the distance between the outside diameter and the inside diameter of the pipe measured in thousandths of an inch. For pipe: Schedule determines wall thickness. It's important to use accurate calipers when measuring this value; a tape measure or well-trained eye are not accurate enough in this case. The relationship between outside diameter and wall thickness has an important bearing on selecting a die.

    Follow the chart of the thread chasing dial in the manual. When you repeat, disengage 1/2 nuts and move the carriage back, then engage half nuts again on the same number or line when the thread chasing dial turns on. The manual shows how to cut the metric and inch threads. Please contact us if you need copy of manual.
  • Do we carry bigger 3 & 4 Jaw chucks for GMC lathes, such as 20" or 24"?
    We do not offer bigger chucks. Unfortunately, 24" is too big; you will have to use very slow speeds, and even then, the part cannot be heavy. Otherwise, it may damage the spindle at the customer's risk. We recommend using a face plate, and they make a fixture to hold their large parts.
  • Will the 16 x 40" Heavy Duty Precision Gap Bed Lathe w/ DRO accommodate a 12" chuck?
    GML-1640HD is small lathe so it cannot hold big chucks due to the chuck weight, it comes with 8” 3 jaw and 10” 4 jaw chucks, the max 4 jaw chuck is 12”.

    It does not matter the material thickness or width, as long as they meet the roll minimum thickness specification.
  • Preventive maintenance schedule for the PSR-5016 Slip Roll Machine
    Keep the machine clean and grease any zerk fitting. You can add a little oil to the chain if you want to, but make sure there is no grease as it will collect dirt.
  • What's the major difference between HBR and PBR models?
    Power plate rolls, also known as mechanical plate rolls, use mechanical force to bend the metal plates. The power for bending comes from an electric motor that drives the rolls. Power plate rolls are generally more straightforward in design and operation compared to hydraulic plate rolls. (review specification) Hydraulic plate rolls, as the name suggests, use hydraulic force to bend the metal plates. The hydraulic system provides the force required for bending, allowing for greater control and precision in the bending process. Hydraulic plate rolls are often preferred for their versatility and ability to handle a wider range of materials and thicknesses. If you are doing cone attachments this machine is for you. Power plate rolls tend to be more affordable compared to hydraulic plate rolls, making them a more cost-effective option for certain applications. It's important to note that specific models have different features and capabilities, so it's always recommended to review the specifications and capabilities of the particular machine you are considering understanding the differences and choose the one that best suits your requirements.
