QIBR - BNF 2005-5 Ball Screw Optimization

Adjustable Dimensions: The screw shaft's terminal end is unprocessed, allowing for additional machining to customize the shape and size according to the customer's ball screw requirements.

Process Optimization: The geometry of the threads and balls is optimized to increase contact area and load capacity.

Further Customization:QIBR can design and optimize ball screws according to customer drawings and operating conditions.

More customization: QIBR can design and optimize the ball screw according to customer requirements for drawings and ball screw working conditions.

QIBR - BNF 2005-5 Ball Screw Quality Control

Dimension measurement: Use a variety of professional high-precision instruments to measure multiple dimensions of the ball screw, with a maximum accuracy of 0.001mm.

Hardness measurement: Use a hardness tester to measure the surface hardness of the guide rail, with a measurement accuracy of ±0.5HRC.

Roughness measurement: Use a surface roughness meter to measure the surface roughness of the ball screw, with a maximum accuracy of ±0.01μm.

Load measurement: A load is applied using a force sensor, and the deformation of the ball screw is measured with a micrometer.

Geometric tolerance: Use a profiler to measure the geometric shape and relative position of the ball screw.

Raw material control: Procurement of steel and parts from ISO 14001 certified suppliers ensures product stability while promoting sustainable development.

Features & Benefits

BNF 2005-5
The screw is the main part of the ball screw, usually made of metal material, with a thread structure. The thread on the screw is usually a triangular thread, which is used to contact the balls inside the ball screw bearing, and generate a driving force when the screw is turned, thereby achieving linear motion.
The nut is a part that matches the screw, usually made of metal, with a thread structure inside that matches the screw thread. There is also a guide groove inside the nut for accommodating the ball.
