Machines are CE and CA marked, with installation, training and technical support available from Ajax Machine Tools.
What’s the best machine for teaching CNC milling on ? An Ajax AJPR220 which has an industry standard CNC control, its on wheels and runs off a 3 pin household plug.
Ajax AJPR220 Mini CNC Milling Machine
The entry level AJPR220 is a compact CNC milling machine with viewing windows on three sides, making it particularly suitable for training and education. The fully enclosed guarding provides operator protection while helping to contain swarf and coolant within the machine.
The AJPR220 is compact enough to pass through a standard single doorway and can be moved on its own wheels, making installation and relocation straightforward. It operates from a standard 3-pin electrical socket and is fitted with the industry standard Siemens 808D CNC control, capable of simultaneous 3-axis contouring.
The AJPR220 is ideal for schools, colleges, training centres, prototyping, small workshops and users looking for a compact, easy to install CNC milling machine.

Frequently Asked Questions
What is a mini CNC milling machine?
A mini CNC milling machine is a compact computer controlled machine used to accurately cut and shape materials such as aluminium, steel and plastics. Its smaller footprint makes it ideal for schools, colleges, training centres, prototyping and smaller workshops where space is limited.
What materials can a mini CNC milling machine cut?
A mini CNC milling machine can machine a wide range of materials including aluminium, steel, brass and engineering plastics. The materials that can be machined will depend on the machine, spindle and tooling being used.
Is a mini CNC milling machine suitable for schools and colleges?
Yes. A mini CNC milling machine is ideal for schools, colleges and training centres because it provides students with hands-on CNC machining and programming experience while requiring much less space than a full-size machining centre.
What CNC control does the Ajax AJPR220 use?
The Ajax AJPR220 is fitted with a Siemens 808D CNC control, providing an easy-to-use system for CNC programming and simultaneous 3-axis contouring.
Can the Ajax mini CNC milling machines be supplied with a 4th or 5th axis?
Yes. Ajax mini CNC milling machines are available with additional axis options depending on the model. A 4th axis option is available across the range, while the AJPR300 is available in 3, 4 or 5-axis versions.
How much does a mini CNC milling machine cost?
The cost of mini CNC milling machine depends on the machine specification, CNC control and any additional options required, such as a 4th or 5th axis, tooling and work holding. Contact Ajax Machine Tools for advice and a quotation to suit your requirements.
Can Ajax mini CNC milling machines be delivered worldwide?
Yes. Ajax Machine Tools can arrange worldwide shipping for its mini CNC milling machines, providing door to door delivery to customers in the UK and overseas.
