Kitamura’s Bridgecenter-8F Double Column Vertical Machining Center offers #40 or #50 taper spindle options for the flexibility needed in the heavy duty cutting of molds to the high-speed, high accuracy cutting required for high precision parts. Both configurations offer positioning accuracy of 0.000078” and repeatability of 0.000039” – The Bridgecenter-8F is the perfect machine for large, long parts that require a wider machining area, most often associated with the Aerospace, Defense and Mold/Die industries.
The design of the Bridgecenter-8F allows for a reduction in fixturing and set-up of parts that would otherwise generally require more than one machine to complete. In addition, the Bridgecenter-8F offers the operator wide door openings and an expansive table work area for easy loading and unloading of parts up to 98.4”L x 42.7”W x 30.3” in height.
Bridgecenter-8F Features
The basic construction of the Bridgecenter-8F consists of a bed type casting with square section support columns, incorporating a triangular section cross beam for an even distribution of weight during heavy cutting, standard linear scale feedback ensures optimum accuracy on a machine of this size. Construction of the Bridgecenter-8F combines super-finish, ground-hardened solid box ways on all axes with high grade Meehanaite castings to deliver outstanding accuracy with excellent vibration damping capabilities.
On the #40 taper configuration, a 20,000rpm, 4 speed gear driven spindle is standard for lighter cuts with fine-finish capabilities at higher speeds. The #50 taper configuration offers 3 spindle speeds (3,500rpm, 6,000rpm, 10,000rpm) for heavy duty, high torque cutting. The optional 10,000rpm 2-speed gear driven spindle allows for an impressive maximum output torque of 199.2ft•lbs with fine finish capabilities. Standard on the #50 taper machine is a 30 HP AC spindle motor with a 2-speed, 3,500rpm gear driven spindle allowing the Bridgecenter-8F to reach full power at 317rpm with a maximum output torque of 490ft•lbs (both 3,500rpm & 6,000rpm) for the ability to handle the toughest of materials and the heaviest of cuts. The Dual Contact Spindle design is standard on both machine configurations and offers the benefits of greater machining rigidity, improved surface finish, higher cutting accuracy and extended cutting tool life.
The Bridgecenter-8F is equipped standard with high speed rapids of 945ipm on the X, Y and Z axes – the fastest on box ways for a machine in this class.
A 30 Tool upgradeable ATC is standard with a 2.8 tool-tool change time. The Bridgecenter-8F is available with 4th/5th axis interface upgrades allowing for the machining of more complex multi-sided parts. In addition, a 2-station automatic pallet changer is an available option for fast change over at a moments notice.
Kitamura combines many standard features in our Kitamura-Fanuc 16iMB control for maximum flexibility in a variety of machining environments. Standard features include 1280 meters memory, 16MB Data Server, HPCC by RISC Control, NURBS Interpolation, manual guide conversational control function and Ethernet connection. This control is powerful enough to ensure optimum accuracy.

Kitamura’s Mycenter-HX630i Horizontal Machining Center is designed for the precision, accuracy and repeatability necessary to produce close tolerance parts from the toughest of materials. The induction hardened solid box way design, combined with high grade Meehanite casting offers the stiffness needed for true high precision, hard milling. Guideways are equipped with ultra high precision twin ball screws and twin servo motors that provide the capability of running speeds of 1969inch/min with accuracies of +-0.00008” Full Stroke and repeatability of +-0.00004”. Total weight on the Mycenter-HX630i is a sturdy 45,100Lbs.
The Mycenter-HX630i is a productive and efficient workhorse, designed to meet the most demanding and advanced applications usually found in the automotive, oil and gas field machinery, aerospace and heavy machinery equipment industries.
Mycenter-HX630i Features
The HX630iF comes standard with a 40HP, 12,000rpm 2-step geared spindle that delivers 323.8ft/lbs of max. Torque with high end power - The only 50 taper machine in its class that offers the versatility for roughing with fine finish capabilities in a single set-up. An optional 5,000rpm high torque spindle is an available option with output max. Torque of 679.3ft/lbs. The combination of Kitamura’s unique spindle gear system with a Dual Contact Spindle design offers the benefits of greater machining rigidity, improved surface finish, higher cutting accuracy and extended cutting tool life.
The Mycenter-HX630i comes standard with full 360° 4th axis simultaneous machining capabilities needed to machine complex, multi-sided parts, greatly reducing set-up time. In addition, Kitamura’s 2-station automatic pallet changer allows for the loading of parts while machining – dramatically improving spindle cutting time while allowing for in-process verification of component quality. Maximum work size of 39.4Ø x 43.3” high with a table load capacity of 2,640Lbs allows for the machining of larger work pieces and complex fixturing. Up to 8 pallets can be added in field to give you added flexibility as the needs of your shop grow. Optional Flexible Manufacturing Systems are also available and easily expandable to meet high precision, production machining requirements.
The HX630i comes standard with a 50-tool fixed pot ATC with an amazing tool-to-tool change time of 1.5 seconds. Up to 200 tools can be added in the field for added flexibility in changing from one job to the next. A Double Decker Conveyor and Filtration System combined with chip augers in the machine bed removes chips with a high amount of efficiency minimizing thermal distortion while improving accuracy and prolonging tool life. In addition, 220psi Coolant thru the spindle is standard on the HX630i to maximize heat dissipation during hard milling.
Horizontal machining requires a user friendly and responsive control when challenged with high precision machining of tougher materials and alloys. Kitamura combines both in our Kitamura-Fanuc 16iMB control. With standard 1280 meters memory, 16MB Data Server, HPCC by RISC Control, NURBS Interpolation and Ethernet connection this control is powerful enough to ensure optimum accuracy in a variety of cutting conditions.
