Cylindrical grinding machine X-35100CAM

for shaftworkpiecehorizontal

INTRODUCTION
TOPKING's X-CAM series is engineered for grinding eccentric and non-circular components including camshafts, crankshafts and polygon punches. Suitable for automotive, automation and mold production. The machine integrates SIEMENS SINUMERIK ONE control with the TOPKING GUI to streamline parameter setup and deliver high-precision operation.

CAPACITY

• Swivel Over Table: Ø370 mm
• Distance Between Centers: 1000 mm
• Max. Grinding Diameter: Ø350 mm
• Max. Grinding Length: 1000 mm
• Max. Load Between Centers: 150 kg

MACHINE FEATURES
USER-FRIENDLY OPERATION SYSTEM
Equipped with SIEMENS SINUMERIK ONE and TOPKING graphical conversational interface. Optional CAD/CAM graphical programming enables custom grinding cycles and simplified setup.

RIGID MACHINE BASE
Meehanite cast iron base with annealing and aging treatment. Slideways are high-frequency hardened and precision ground. 1V1 flat guideway and reinforced sliding seat ensure structural rigidity and stability.

WORK TABLE
Worktable permanently bolted to the machine. Cross-slide layout reduces travel and improves processing speed and positional stability.

CROSS-SLIDER DESIGN & AXIS GUIDANCE
X and Z axes adopt a cross-slide configuration; wheelhead traverses on Z axis to reduce footprint. X-axis uses box-way support to withstand grinding forces and a 1V1 flat guideway with wear protection.

X-AXIS DRIVE BY LINEAR MOTOR
X axis is directly driven by a linear motor to eliminate backlash. Closed-loop control with linear scale; peak moving speed up to 15000 mm/min. Linear motor construction reduces attrition for long life and energy efficiency.

WHEELHEAD CONSTRUCTION
Grinding spindle uses precision bearings. G.W. spindle machined from SNCM-220 with normalization, quenching, tempering, carburizing and cryogenic treatment, then precision ground and mirror-finished. Surface hardness > HRC62 for stable high-precision performance.

WORKHEAD - C AXIS PRECISION ANGLE CONTROL
Work spindle equipped with direct-drive motor and high-resolution angle encoder. Angle tolerance ±0.2” suitable for eccentric, camshaft, crankshaft and polygon punch grinding. Micro-adjustment available for taper correction.

FINE ADJUSTMENT TAILSTOCK
Automatic oil-bath lubrication for tailstock with oil level gauge. Tailstock supports taper correction in centers-fixed grinding.

G.W. DRESSING
Multiple dressing device options with graphical dressing interface. Diamond roller dresser available for wheel and component dressing.

G.W. JIB CRANE
Standard jib crane for loading/unloading grinding wheels, base-mounted on the machine and covered by splash guard.
