The MW35 all-electric, compact turning center with a servo high-speed loader (single or twin gantry loaders are available) is said to produce small parts in as little as three seconds. The machine has two spindles capable of simultaneous multi-tool cutting. The MW40 is designed for minimal thermal displacement during machining operations of smaller parts with tight tolerances. The machine is available with live tooling and Y-axis milling capability.
The MW120 twin-spindle CNC turning center reduces cycle time with a high-speed gantry loader and turret axes. The machine is capable of production times as low as 16 seconds per part. The MD120 automated CNC turning center accommodates live-tooling capabilities, including drilling and milling in every turret position. The integrated three-axis gantry robot loader enables versatile automation possibilities with increased productivity and process flexibility.
The MT100 opposed spindle machine has a built-in Y-axis for greater precision on complex parts, the company says. The machine is designed for each turret to serve either of the twin spindles. Upper and lower turret configuration enable the flexibility to manage two tools in a single cut while reducing cycle time. A variety of automation options include an optional third turret and a three-axis gantry robot. The MT200 opposed-spindle-type machine accommodates larger parts with a turn diameter ranging to 8.3" and an 8" chuck.
Running rotary milling cutters at the proper speeds and feeds is critical to obtaining long tool life and superior results, and a good place to start is with the manufacturer's recommendations. These formulas and tips provide useful guidelines.
The more common twist drill point geometries often are not the best for the job at hand. By choosing the best point for the material being drilled, it is possible to achieve better tool life, hole geometry, precision, and productivity.
Cutting holes by interpolating a face milling cutter may be a better process choice for many rough and even finish boring operations. Software improvements and better cutter designs allow expanding use of the versatile face mill for hole making.
