X-2540CAM
CNC CAM grindingINTRODUCTION
The TOPKING X-2540CAM is a CNC non-round grinding machine designed for CAM-controlled contour grinding under space-constrained conditions. The machine adopts a cross-slide structure combined with linear motor drives and direct drive systems, enabling zero mechanical backlash and high dynamic response during non-circular interpolation.
Precise C-X axis synchronization supports stable contour generation for non-round profiles. The machine is suitable for grinding polygon punches, small camshafts, eccentric pins, and precision medical components, where consistent μm-level accuracy and repeatability are required.

MACHINE FEATURE
USER FRIENDLY OPERATION SYSTEM
■ Equipped with SIEMENS SINUMERIK ONE control system. Built-in TOPKING’s latest version graph conversational operate interface includes crankshaft and camshaft grinding application. Make work easier! Moreover, operating with CAD/CAM software (optional accessories) easy to programming the custom-made grinding graphics. Provide a flexible and humanized operating environment.
RIGID MACHINE BASE
■ High rigidity machine base made of Meehanite cast iron through annealing and aging treatment.
■ Slideway though high-frequency hardening and precision grinding process. Machine base with stable material and strengthen construction for deformation-free and outstanding wear resistance.
WORK TABLE
■ The work table is permanently bolted to the machine. The cross-slide design is adopted to reduce travel. It can improve working speed and precision stability.
CROSS-SLIDER DESIGN & AXIS GUIDANCE
■ X and axes are designed as cross-sliders to reduce machine space.■The X-axis is driven directly by a linear motor, combined with linear guides, to achieve smooth axial movement. Equipped with a high-resolution linear scale as standard, ensuring stable repeatability precision and guaranteeing utmost precision during the machining process.
■ Two axes covered by enclosed telescopic covers. To protect the transmission structure and prevent contamination from grinding debris and coolant.
X-AXIS DRIVEN BY LINEAR MOTOR
■ X axis is driven by a linear motor directly, with no backlash for achieving more precise position control.
■ Cross-slider construction with high-speed precision linear motor and closed-loop control linear scale on X axis. Apply the smoothest working condition with the C axis.
■ Moving speed could reach 15000 mm/Min.
■ Linear motors constitute of coil and permanent magnets. No attrition for longer uses life and contributes to energy savings and increased efficiency.
WHEELHEAD CONSTRUCTION
Built-in spindle for grinding wheel.
■ The lightweight design of the wheelhead seat mitigates resonances stemming from conventional transmission components, thereby stabilizing the grinding process and elevating machining precision.
■ Built-in spindle proficiently manages and monitors spindle temperatures, effectively safeguarding against thermal deformation issues.
■ Built-in spindle's high-speed rotation and rapid response to acceleration and deceleration enable the fulfillment of speed adjustments and consistency required for intricate contour grinding.
■ Built-in spindle offers lower energy consumption and reduced pollution emissions, achieving benefits in energy efficiency and environmental conservation.
WORKHEAD SPINDLE
■ Working spindle equipped with a Direct Drive motor and precision angle encoder. High resolution of angle tolerance control ±0.2”. Accurate angle control applies for various eccentric, cam shaft, crank shaft, and polygon punch grinding.
■ Could do micro-adjustment for taper correction.
FINE ADJUSTMENT TAILSTOCK
■ An auto. oil bath lubrication system has been provided for tailstock to maintain high-level accuracy.
■ The oil level gauge provides a quick check of the oil level.
■ Could adjust enables taper correction in centers fixed grinding way.
