Small parts manufacturing can pose significant machining challenges for the average job shop. Tiny holes, minute features, extreme accuracies and fine surface finishes may prove difficult for larger CNC machines. Haas Automation's new CM-1 compact mill is a small-footprint, high-accuracy solution for the production and prototyping of small, high-precision 2D and 3D parts, such as those found in the communications, aerospace, medical and dental industries.

The CM-1 features 12" x 10" x 12" travels, a 20" x 10" T-slot table, a 30,000-rpm ISO 20-taper spindle, and a 20-pocket automatic tool changer. Maximum cutting feeds are 500 ipm, with rapids to 757 ipm for reduced cycle times. The user-friendly NextGen Haas control makes set up and operation simple. Standard equipment includes a 15" color LCD monitor, 1 GB of program memory, Ethernet connectivity, a power-failure detection module, a USB port, a coolant system, high-speed machining software, and more. A number of high-productivity options are also available, including a 50,000-rpm spindle and full 5-axis capability.

The CM-1 is small enough to fit into most freight elevators, and can easily be moved with a pallet jack or equipment dolly. The machine runs on single-phase power.

For full 5-axis machining on the CL-1, Haas offers the TRT70, an ultracompact dual-axis tilting rotary table that provides ±120 degrees of tilt and 360 degrees of rotation to position parts to almost any angle for machining. The TRT70 provides 60 ft-lb (81.3 Nm) of torque on the tilt axis and 40 ft-lb (54.2 Nm) on the rotary axis for aggressive machining; and indexing speeds of 410 deg/sec on the tilt axis and 620 deg/sec on the rotary axis ensure short cycle times. The precision-ground 70 mm (2.76") platter features multiple bolt patterns and a precision through-bore for versatile fixturing, and will swing parts up to 4.0" (102 mm) diameter.
