Quick grinding for short wire sections

“Even proven conventional point grinding machines struggle to process sections measuring less than 35mm in length,” explains Managing Director Peter Renz. As a result, shorter needles were previously shortened to the required length. Help is now at hand with the “PG3” and “PG11” needle grinding machines, designed to process sections from 20mm in length and between 0.25mm and 2.50mm in diameter.

Saving time, material and workload

The short blanks are separated from the magazine by a grooved transport wheel before being positioned. A transport unit then coveys them along the grind stone. Peter Renz says: “This special design feature is what enables a shorter passage of the needles over the grind stone.” Customers who use the “PG3” or “PG11” for point grinding on short sections therefore save both time and material. Both needle grinding machines use a magazine system to convey the parts to and from the grinder. This process is automatic and requires no operating personnel. The only manual process is the replacement of the magazine. This reduces staff workload, therefore making the point grinding process more profitable.

Precisely adjustable grinding process

Both machines make it possible to grind concentric point shapes (convex, concave or straight) on sections of varying diameter. The length and shape of the points, along with the machine’s output, can be set precisely via motorized adjustments in the x, y and z axes. The “PG3” and “PG11” needle grinding machines are suitable for a wide range of products. Typical examples include needles used in the medical sector. But they also include everything from fishing hooks to points for perforating thin films or sheets for lithium-ion batteries.

Flexible and reliable solution

These two point grinding machines are an efficient solution for any applications that involve short needles measuring between 20mm and 80mm in length. Lengths of up to 140mm are also possible, depending on the point shape. Thanks to an enclosed machine housing, they are protected and easy to access from all sides. The drive and electronics are also integrated.

Live demonstration of the PrecisionCut UD0

“Our entire exhibition team cannot wait to explain to customers how they can benefit from our wide range of machinery,” says Peter Renz. He is particularly looking forward to presenting the “Precision Cut UD0” straightening and cutting machine in person at the stand. Capable of both straightening and cutting wires measuring from 0.05mm to 1.5mm in diameter and from 3mm to 3,000mm in length, the UD0 is particularly well-suited to medical applications.
