In this section you will learn the basics of the Tormach 770 CNC Mill Standard in our innovation lab. This includes tasks it can complete, material handling , and features of the machine.
What is it?
The Tormach 770 is a computer-controlled milling machine used to shape and cut materials like metal (aluminum, steel, brass), plastic (polycarbonate), and wood (plywood). It’s like a high-tech version of a traditional drill press but much more precise and versatile. This machine is great for prototyping and small-medium scale sized projects, perfectly suited for robotics.
Features
Features:
Work Area: It has a table where you place your material, and it can handle parts up to 30 inches wide and 12 inches deep.
Spindle Speed: The spindle (the part that spins and cuts) can go up to 10,000 times per minute, allowing it to cut through various materials.
Tool Holders: It uses a standard type of tool holder called R8, which makes it easy to swap out cutting tools
What can it do?
Uses:
Prototyping: It’s great for making prototypes of designs—think of it like creating a model before making a final product.
Custom Parts: It can make unique, custom parts for projects or small-scale manufacturing.
Tapping: It can perform tapping operations to create internal threads in materials.
Milling: The primary function of the Tormach 770M is to mill materials into precise shapes and dimensions. It can perform various types of milling operations such as face milling, slotting, drilling, and contouring.
Drilling: With its spindle and tool options, the 770M can drill holes of various sizes and depths into different materials.
How does it work?
The Tormach 770M CNC mill automates the cutting process by using a computer to control its movements and operations. It moves the cutting tool in precise patterns to shape materials according to your digital design. This combination of software and hardware allows for accurate and repeatable manufacturing of parts and prototypes.
1. Design and Programming:
Create a Design: First, you create a digital design or model of the part you want to machine using CAD (Computer-Aided Design) software.
Generate Toolpaths: Using CAM (Computer-Aided Manufacturing) software, you convert the design into a set of instructions or toolpaths that tell the mill how to cut the material.
2. Set Up the Machine:
Load the Material: Secure the material (e.g., metal, plastic) onto the machine’s table. The table has clamps or vises to hold the material in place.
Install the Tool: Choose and install the appropriate cutting tool in the spindle. The tool might be a drill bit, end mill, or other cutting instrument.
3. Load the Program:
Transfer Instructions: The toolpaths generated by the CAM software are transferred to the mill's control system, PathPilot® in this case. This can be done via a USB drive or network connection.
4. Machine Operation:
Automated Cutting: The CNC control system reads the instructions and moves the machine’s three axes (X, Y, and Z) accordingly:
X-Axis: Moves the table left and right.
Y-Axis: Moves the table forward and backward.
Z-Axis: Moves the spindle up and down.
Cutting Process: The spindle, which holds the cutting tool, rotates at high speeds and moves according to the programmed instructions to cut, drill, or mill the material. The machine precisely follows the toolpaths to create the desired shape or part.
5. Monitoring and Adjustments:
Monitor the Process: You monitor the machining process to ensure everything is running smoothly. You can make real-time adjustments if needed.
Finish the Part: Once the milling or drilling is complete, you remove the finished part from the table and inspect it for accuracy and quality.
