ACT Machines is the online division of Advanced Control Tech, GPK Group, Inc., which is a company located in the Los Angeles area of California. ACT Machines specializes in digital motion control, high efficiency brushless motors and the benchtop CNC milling machine and drilling machines. ACT Machines' company founder, Dr. Peter Lee, has a PhD in digital control technology and has been working in the motion control industry for thirty years. The company develops the advanced CNC controller using the latest micro-process chips for the benchtop CNC milling machine. High torque and variable speed brushless motors are used for the spindle driver. ACT Machines (Advanced Control Tech) is proud to introduce the next generation benchtop CNC milling machine. The DMC-111(US Patent No. 7467449) prototype portable benchtop CNC milling machine is lightweight, compact and low cost, and rigid enough for precision cutting of all metals. After four years of research, development and testing ACT Machines is confident that the performance and reliability of the DMC-111 benchtop CNC milling machine will meet all needs and beat any other system in the market. ACT Machines' versatile benchtop CNC milling machine delivers a professional performance at an affordable price for a wide range of projects, which include precision prototype development, low production manufacturing, precision 3D mold making, engraving, jewelry manufacturing, thin plate milling and drilling machining for sheet metal or panels and PC board drilling and PC board test fixture construction.

The benchtop CNC milling machine is also suitable for laboratories, hobbyists and professional schools. ACT Machines provides the fast, low-cost benchtop CNC milling machine which will greatly reduce turnaround times and manufacturing costs. ACT Machines' benchtop CNC milling machine system is integrated into a single piece machine weighing only 260 pounds, movable by two people without having to use a forklift. The cast ion frame and T slot table is ideal for heavy duty machining and rigid enough for all metal machining. ACT Machines' benchtop CNC milling machine features specially designed work piece(s) holding devices for thin plate machining, PC board drilling and electric panel machining, as well as a clamp set to secure the work directly onto the T slot table for machining and no vises are required. All parts of the benchtop CNC milling machine are precision manufactured with final calibrations and alignment and the machine's repeatability is within 0.0001".

The mill features high precision ball screws with zero backlash and the linear guided rails, high quality ball bearings and thrust bearings are used for all three axes and the spindle. The spindle speed can be changed directly from the CNC software in the PC. ACT Machines' patented lightweight compact design for true benchtop CNC mill operating includes a PC with Windows operating system and installed CNC software. The Keyboard, monitor and mouse are not included in the system. ACT Machines' benchtop CNC milling machine toolbox contains clamping devices, ER16 collets and milling bits for turnkey operations. The belt and pulley system is used to isolate any vibration between the motor and the spindle.
