Sterling STC AX CNC Servo Twin-Column Automatic Bandsaw
Sterling’s range of bandsaws are one of the leading brands in the metal cutting world. The STC AX CNC range is designed to maximise our customer’s production of heavy metal beams, profiles, and pipe cuts in high-volume quantities, with a fully automatic servo feeding and cutting system. Automatic controls and sensors maximises the performance to cost ratio, and extends the lifetime of a blade up 50% longer.
For further improved safety – the machine can be supplied fully enclosed.
The Omron Touchscreen CNC controller on this saw enables the user to set-up to 100 programmes with 50 steps each for automatic cutting, simply punch in your lengths and quantities, and let the saw do the work for you.

A built-in flood coolant system helps to not only prolong blade life, but assists with a cleaner cut, preventing overheating and warping of blades. The hydraulic gravity down feed allows you complete control of the speed of the cut, ensuring the drop of the blade suits to the material that you are cutting, with the automatic stop, the blade will stop spinning once the cut is complete, allowing for safer worker interaction.
Ideal for cutting round, square or rectangular section, bandsaws like this Sterling STC X CNC are the mainstay of virtually any fabrication shop in the UK. We offer a wide range of Sterling and Bianco Bandsaws, to fit with your cutting requirements, look at the rest of the range here.
We can also supply blades and coolant too, these can be purchased directly off our tooling website. All of our Saws are supplied with a starter set of our Goldcut Blades, we will discuss with you the material you will be cutting to ensure they will meet your requirements and a free container of coolant, so your new saw is ready to begin cutting straight away as soon as it’s delivered to you!

Frequently Asked Questions
What is the Sterling STC AX CNC Servo Twin-Column Automatic Bandsaw designed to cut?
The Sterling STC AX CNC Servo Twin-Column Automatic Bandsaw is aimed at high-volume cutting of heavy beams, profiles, pipe and large sections. The published range covers STC335, 420, 570, 660 and 825 AX CNC. Suitability for a particular grade or section should be confirmed against the actual job and model.
What cutting capacity is available on the Sterling STC AX CNC Servo Twin-Column Automatic Bandsaw?
The published range includes 335mm, 420mm, 570mm, 660mm and 825mm round respectively. Capacity changes with material shape and, where relevant, mitre angle, so compare the correct model and angle in the Selmach specification table.
How does the automatic cutting cycle work on the Sterling STC AX CNC Servo Twin-Column Automatic Bandsaw?
The machine uses servo-driven material feeding and bow movement with an Omron touchscreen CNC controller. This reduces repeated operator input between cuts, although loading, safe setup, blade selection and checks remain essential.
Can the Sterling STC AX CNC Servo Twin-Column Automatic Bandsaw make mitre cuts?
The published STC AX CNC specification lists straight-cut capacities; confirm any angled-cut requirement before ordering. Check the product specification for the exact material section and cutting angle before planning production.
Which bandsaw blade is used on the Sterling STC AX CNC Servo Twin-Column Automatic Bandsaw?
The published blade specification is 5260 × 41 × 1.3mm on the STC335 AX CNC up to 9500 × 67 × 1.6mm on the STC825 AX CNC. Blade tooth pitch and grade should be chosen for the material, wall thickness and cut frequency; Selmach can advise on suitable replacement blades.
What features or options are available for the Sterling STC AX CNC Servo Twin-Column Automatic Bandsaw?
For this range, up to 100 CNC programmes with 50 steps each are described; full enclosure is an available option on the STC420 AX. Check which features are standard and which are optional on the quoted model, particularly if coolant management or material handling is important.
What should operators check when maintaining the Sterling STC AX CNC Servo Twin-Column Automatic Bandsaw?
Follow the machine manual and isolate the saw before maintenance. Routine checks should include blade condition and tension, guides, coolant, swarf removal, vice operation and the feed system. A useful specification point is: The listed cutting-speed ranges are generally 15–150m/min, except the STC660 AX CNC at 15–120m/min.
Can Selmach provide a Service Plan for the Sterling STC AX CNC Servo Twin-Column Automatic Bandsaw?
Ask Selmach about a Service Plan and aftersales support for the Sterling STC AX CNC Servo Twin-Column Automatic Bandsaw. The recommended service schedule and any included visits or parts should be confirmed for the exact machine, its age and operating hours rather than assumed from the product page.
