Welcome to the Bochi North America question and answer page. This page was created for machining help with CNC/Manual mills and lathes as well as general machining help. If you have a machining question please fill out the form to the right with your question and a specialist at Bochi North America will answer below on this page. Please use this page for help and advice only and keep the questions based on machining. Thank you for your cooperation.
A CNC Machine is a machine that is computer numerically controlled. This meaning that numerical points are imputed through a computer to the machine to either remove or add materials to these pre-programmed points.
CNC Machine is a term that includes many different types of machines. Each type has different price points. Based on our estimates we have composed of the following price points.
Hobbyists can get started with a CNC Router for $3,000 to $5,000.
Machine shops can expect to spend $30,000 to $80,000 on toolroom machines.
Production Machining can expect to spend a minimum of $60,000 per machine.
Lastly any 5 or more axis machine will cost $200,000 or more per machine.
When selecting the orientation of your lathe it is primarily based on your work-piece style. With a vertical lathe you can have gravity help hold your work-piece in place which is very effective with large and heavy work-pieces. Secondly working with gravity on your side can increase production by applying more cutting force and removing more material. Primarily if you have a large disk shaped work-piece, go vertical. Any small work-pieces or long work-pieces, go horizontal.
A toolroom lathe simply put is a lathe in a toolroom designed for simple toolroom work. They are typically a higher quality than standard engine lathes or center lathes. You can typically expect a toolroom lathe to have a gearbox in the headstock, better accuracy, and offer ranges of pitches and feeds for threading.
A lathe typically consists or 2 or 3 axes. They do not have a milling feature and operate by only removing materials well rotating the spindle. A turning center will typically consist of 3 or more axes and have the ability to turn or mill parts. You may want to choose a turning center over a lathe for making more complex parts that have to be turned and have features milled.
The major benefit of 5-axis milling is the machining of complex parts. This includes shapes and angles that can only be achieved by 5-axis machining and less set up on standard complex parts. Parts that are being machined on many sides could be done in a 3-axis mill but would require separate setup to machine each side compared one setup for all sides except for one clamped.
When discussing types of materials to be cut we tend to look towards the tool rather than the machine. Most all standard manufacturing materials can be cut on lathes and mills. It will depend on cutting speeds and proper tooling.
