Precision Sawing
Stelstocks specialise in offering precision sawing solutions that are specifically aligned with our customer requirements, providing specific bar feed lengths or individual billets.
Bars can be sawn to close tolerances by both length and weight. Our high performance machines can offer sawing solutions from one off cutting, to high production batches, in size ranges from 12mm up to 340mm diameter, in both Round and Hexagon bars.
Bar Facing & Chamfering
At Stelstocks we are aware that the condition of the bar ends can have a huge impact on your machining process, therefore, we can supply our bars with either a full face, or a chamfer, to meet your requirements.
We can chamfer bars from 12mm up to 70mm in diameter, with an angle between 30 and 60 degrees.
Hexagon Roller Marking
Roller marking is the process by which inscriptions are marked on a material, continuously over a fixed length.
Stelstocks can mark Hexagon bars within the size range of 14mm to 60mm across the flats.
Obverse Flat Marking is also available.
Non-Destructive Crack Detection
Stelstocks can offer a wide group of analysis techniques used to evaluate the properties of a material without causing damage. Our high speed and reliable testing will ensure products are free of harmful defects, maximising their productivity and reliability.
Magnetic Particle Inspection (MPI) is a non-destructive testing (NDT) process for detecting surface, and shallow subsurface discontinuities in materials such as steel. The process puts a magnetic field into the part.
We provide Surface Crack Detection by M.P.I. or equivalent methods, to BS 6072 & Euro Standard BS EN 1290
Ultrasonic testing (UT) is a family of non-destructive testing techniques based on the propagation of ultrasonic waves in the object or material tested. In most common UT applications, very short ultrasonic pulse-waves with center frequencies ranging from 0.1-15 MHz, and occasionally up to 50 MHz, are transmitted into materials to detect internal flaws or to characterize materials.
We can provide Ultrasonic Testing to BS 5996 & Euro Standard BS EN 10160
Grinding
Centreless grinding is a machining process by which material is removed from steel bars or components by means of abrasive cutting or grinding.
No spindle or fixture is used to locate and secure the bar; the bar is secured between two rotary grinding wheels. The speed of their rotation relative to each other determines the rate at which material is removed from the bar.
Full bar lengths are straightened and ground to tight tolerances for an enhanced surface finish.
