INTRODUCTIONTOPKING's X-2540A is a CNC angular cylindrical grinding machine designed for simultaneous outside-diameter (O.D.) and end-face grinding in a single clamping. The integrated angular wheelhead and cross-slider X/Z design reduce setup time, shorten production cycles and deliver consistent precision with simplified programming via a GUI-based CNC control.
CAPACITY- Swing Over Table: Ø270 mm
- Distance Between Centers: 400 mm
- Maximum Grinding Diameter: Ø250 mm
- Maximum Grinding Length: 400 mm
- Maximum Load Between Centers: 15 kg
- Center Height (table to center tip): 135 mm
MACHINE FEATURES- GUI-based CNC control for process segmentation, numeric dressing and simplified editing without manual G/M coding.
- Rigid Meehanite cast-iron base with annealing and aging treatment; hardened and ground slideways for long-term stability.
- Permanently bolted work table and cross-slide layout to reduce travel and improve speed and positional stability.
- Compact cross-slider arrangement for X and Z axes; enclosed telescopic covers protect transmissions from coolant and debris.
- High-enclosed linear scales on X and Z axes as standard for accurate positioning and finish quality.
- Precision linear guides and ball screws for low friction, high load capacity and minimal backlash; supports flexible feed modes for small components.
- Angular wheelhead with G.W. spindle using precision bearings; spindle material SNCM-220 with multi-stage heat treatment and grinding to >HRC62 for wear resistance.
- Servo-driven workhead with stepless speed; optional hydraulic tailstock; flat-air-pressure design to reduce friction and center heating; central cooling to prevent deformation.
- Diamond tool holder (tailstock-mounted) with standard dressing device; multiple dressing options available.
