Higher accuracy for smaller applications
IBAG North America has introduced a micro collet system that can achieve higher accuracies for precision milling and ultra small drilling applications becoming increasingly common in the medical industry and other micro manufacturing applications. The new system delivers accuracies of one micron T.I.R at the collet nose and handles up to 1/8” tool diameter, and is equipped for use with 22, 25 and 33 mm IBAG Micro Line high speed spindles, including back working and right angle models. Spindle speeds up to 90,000 RPM are possible, significantly reducing cycle time and boosting productivity.

New insert designs for exchangeable head milling system
October 1st sees the launch of 3 new styles of inserts for the CoroMill 316 exchangeable head milling system. The 3 new designs of end mill, each with 2 cutting edges, extend the depth of cut for the CoroMill 316 range to 0.8 x Dc, making them versatile problem solvers with maximum strength and security. The new range features a ballnose for profile milling, aluminum machining and finishing, and has a strong cutting edge for profile roughing. Other features include a corner radius for slot milling, shoulder milling, plunge milling, face milling, ramping and pocketing, excellent for chip evacuation problems when slot milling, and finally a chamfer for chamfer milling of different angles and optimised for spot drilling capability. The system of exchangeable end mills are connected to a tool shank by a unique threaded coupling which combines high-strength with guaranteed accuracy. The tool is based on CoroMill Plura geometries and is available in the latest PVD grade technology.

5-axis cryogenic machining for mega-size parts
MAG’s modular HMC 1250/1600 Series uses cryogenic tool cooling technology and a new cryogenic-equipped A-axis tilt-spindle for 5-axis horizontal machining on large parts. The HMC1250/1600 Series is engineered for high-precision, high-productivity machining of large aerospace, power generation, pump, valve, and off-road equipment parts. It now includes six spindle options to suit special-purpose or general machining requirements. Standard on the live spindle, MAG’s exclusive Z-axis thermal compensation software dynamically offsets spindle growth to maintain tight tolerances. Powerful and agile, the new HMC offers 56 to 80 kW (75 to 107 hp) spindle power, 35 kN (7870 lb) Z-axis thrust, and super-rigid, full-contouring hydrostatic rotary table. The 360,000-position contouring table provides a rigid work platform, while a rugged worm gear drive with clamp securely holds axis position. Rotary table positioning accuracy is 10 arc seconds, repeatable to 5 arc seconds. Positioning accuracy of the tilt-spindle is 4 arc seconds, repeatable to 2 arc seconds. Meeting industry needs for tighter part tolerances and greater machining accuracies, the HMC Series comes standard with linear scale feedback in X, Y and Z axes, providing 8 micron (0.0003 in) positioning accuracy and 5 micron (0.0002 in) repeatability.

Drilling and plunge milling with a single tool
KOMET’s Quatron hi.feed milling cutters boosts roughing operations by enabling machinists to use the four-effective indexable inserts for both drilling and plunge milling. The Quatron indexable inserts also have a radial cutting action, which affords a considerably higher degree of flexibility in plunge and pocket milling by comparison with two- or three-edged inserts and adds rapid removal of high chip volumes. Machinists who need to cut deep grooves or large cavities in their workpieces often opt for plunge milling due to the dimensions or cutting capacities of the tools or the performance of the spindle inside the machine. Rather than boring with the use of multiple boring tools, it is possible to achieve various diameters and complex contours in one roughing operation by milling with an axial and a horizontal feed. The KOMET Quatron hi.feed can use the very same indexable inserts for drilling as well as milling. The proven BK8425 coating delivers exceptional tool life while enabling universal use of these milling cutters for steel, cast iron and stainless materials.

New series vertical machining centers
Makino’s PS-Series machines are the new standard in vertical machining centers for production machining, offering a reduction in cycle time, increased productivity, improved quality and minimization of capital investment. The PS-Series features a field-proven design with key technologies from several of Makino’s most reliable production machines. Its rigid construction, thermal stability and versatile spindle are ideal for a variety of applications, including automotive, aerospace, medical and other small-component manufacturing applications. Makino’s PS-Series comes standard with a high power 33.5 HP, high speed 14,000-rpm CAT40 spindle delivering 130 ft-lbs peak torque. The PS-Series is available in two models: the PS65 and PS95. The smaller PS65 features X-, Y- and Z-axis travels of 26”, 20” and 18.1”, respectively; a 36.2”-by-20” table; and a maximum workload of 1,323 lbs. The larger PS95 features X-, Y- and Z-axis travels of 36.2”, 20” and 18.1”, respectively; a 46”-by-20” table; and a maximum workload of 1,763 lbs. Both models are equipped with an easy-to-access, highly reliable, 30-tool-capacity automatic tool changer (optional 50-tool capacity available).
Large-diameter bearings, air-oil lubrication and jacket-spindle temperature control deliver long-term thermal stability and stiff, rigid, chatter-free cutting. Created with the production environment in mind, the PS-Series chip and coolant systems enhance the productivity of the machine. Configured with flood, overhead shower, flush and through-spindle coolant as standard features, chips are efficiently and effectively removed from the cutting zone. Spiral chip augers located in the front and rear of the worktable quickly and efficiently evacuate chips and coolant from the machining zone and into a standard lift-up chip conveyor.

Newly designed horizontal boring and milling machine
The new Nissin HBM BHP130-3.5 Series Horizontal Boring and Milling Machine from SNK America, Inc. is rigidly designed for accurate and tough prolonged cutting.The heavy, high quality cast iron construction of the HBM BHP130-3.5 is complemented by the scale feedback of the worm and wheel. Large worktables, featuring nine T-slots, simplify work fixturing. The HBM BHP130-3.5’s extra-wide solid boxways, precision finished using SNK’s “Mirror Surface Finish” technology, easily accommodates the largest parts. Oversized ballscrews on all linear axes provide consistent precise positioning in the most demanding machining conditions.

New high-torque spindles combine increased power with precision
REM Sales, LLC (Windsor, CT), the exclusive North American importer of Tsugami machine tools announces that selec 20mm models will now be equipped with a new higher torque main spindle. The new 10,000 rpm higher torque spindles will boost metal removal and productivity without sacrificing precision. Affected models include the B0203/204/205, S205/S206, BH20, BE20-V, SS20, and the S207. Previous to this announcement those models were equipped with a 12,000 rpm main spindle. Tests have shown the new higher torque spindles provide three times the metal removal capability of previous models in certain applications. Turning cutting area has been increased from 0.15 mm2 to 0.50 mm2. Drilling and tapping power has also been boosted. Tapping capability has been increased from M8 in Swiss configurations and M6 in chucker configurations to M10 in both.
