Numberall can modify our marking tools to suit many applications. In this example the customer was stamping a part that needed to be a curved line. Also, clearance issues required a unique modification. The engraving not only had to be offset to produce a curved line, it had to be adjusted to stamp 30 degrees from normal. (more…)

Numberall is known for products that last for decades. To make sure your machine lasts a long time, regular maintenance must be done. It is almost always more cost effective to perform regular maintenance than repair a damaged machine. The Model 50P is a machine that is a fine example of this. In fact, we are still servicing Model 50P numbering heads that are over 40 years old, a true testimonial to Numberall’s quality and design.
This list, along with your Model 50P owner’s manual, will help you to maintain your machine:
- Coil Return Springs. The coil return springs are part of the head of the Model 50P. These springs are under considerable tension and should be handled carefully. They are not required with the air trip feature, however, they will experience the most wear due to their location on the machine.
- Actuating Pawl. When removing the actuating pawl shaft, be careful not to drop the actuating pawl as it is easily broken.
- Actuating Pawl Spring. When maintaining your machine, always wear eye protection as the actuating pawl spring is under tension and could fly out. It can break prematurely due to wear, so it is recommended to keep one in stock.
- Retaining Pawls (Regular). Be careful not to bend the retaining pawls when using or maintaining your machine. If the retaining pawls are to be removed, maintain the original order for reassembly.
- Retaining Pawl (Unit). Care should be taken not to bend the retaining pawl shaft when using or maintaining your machine.
- Retaining Pawl Spring. Retaining pawl springs on numbering heads can break prematurely, so it is recommended to keep them in stock.
- Spare Wheels. Depending on use and the material being stamped, it is recommended to keep spare wheels in stock.
- Medium India Stone. If there are any burrs on the wheels or actuating arms, make sure to remove them using a medium India stone.
- Light Machine Oil. Lubricate the Model 50P. Care must be taken to ensure that dirt and grit are not in the machine before lubricating it. The tolerances are very tight, so any dirt and grit in the machine may bind or damage it. Do not lubricate a head that is to be heated as the oil will leave residue, which will bind the machine.
The location of these parts will vary on your machine based on options you’ve selected. However, the owner’s manual provides detailed images to help you identify them.
