Equipped With

The KENT USA KHC-320 Compact CNC Horizontal Machining Center combines proven machine design with advance technology in control and manufacturing.  Reliability and performance makes these a favorite among demanding job shops and in-house production alike.  The one-piece machine casting base with traveling column design provides a solid foundation for high volume small parts precision machining.  The direct driven spindle and rigid machine structure enable higher machining efficiency with better finish and longer tool life – resulting in greater productivity and profitability all around.  Upgrade your global competitiveness today.

OUTSTANDING FEATURES:

• Compact space saving design with dual 320 x 320 mm (12.5” x 12.5”) Pallets
• Servo driven automatic pallet changer for fast 7 seconds pallet change time
• 24 tools Dual Arm Swing-type ATC with fast 1.2 second tool change time
• Convenient tool storage built-in on side of machine enhances operator efficiency
• Column traveling design for X/Y/Z Axes with high precision Linear guide ways

DIRECT DRIVE SPINDLE

Direct driven spindle design offers greater static/dynamic load stiffness with less vibration and noise for better surface finish and longer tool life.  An optional “built-in” type spindle is available for 25,000 and higher RPM applications.

SERVO DRIVEN PALLET CHANGER
The standard servo driven pallet changer offers faster pallet exchange speed with better positioning accuracy and precision, increasing overall reliability for maximum productivity.  Pallet change time is 7 seconds.

LOCKING TAPER 
Each table has 4 taper cones for precision positioning and clamping by hydraulic system.  Air blow and sensors ensure smooth and reliable operation.  Repeatability is +/- 0.005 mm (+/- 0.0002 inch) or less

The compact space saving design with enclosed back and side guarding helps to comply with industrial safety regulations.  Chain type chip conveyor and chip cart for easy and convenient maintenance without impacting production cycle times.
