The STK-100NC Automatic Metal Cold Saw Cutting Machine is engineered for high-speed cutting of solid metal bars, thick-wall tubes, and compatible non-metallic materials. It combines an 11 kW spindle motor, servo-controlled feeding, hydraulic workpiece clamping, and a 360 mm circular saw blade to support repeatable cutting operations in industrial production.
The machine uses a horizontal cutting feed driven by a servo motor and ball screw. Its rigid machine structure, automatic material loading arrangement, and programmable control system help coordinate material handling and cutting operations.
The STK-100NC is intended for manufacturing environments where metal stock must be cut into specified lengths before subsequent machining or assembly.
The machine bed uses a reinforced structure and heat-treated ductile cast iron to support the cutting mechanism. The construction is designed to provide mechanical rigidity and reduce the effect of vibration during cutting.
The spindle assembly uses a precision gearbox and an 11 kW main motor. The documented saw-blade speed range is 53–120 rpm. Cutting parameters should be selected according to the blade specification, material grade, and workpiece dimensions.
A servo motor and precision ball screw control horizontal movement of the cutting head. The feed mechanism is intended to provide controlled blade engagement during cutting and support consistent cutting operations.
The main clamping system secures the workpiece from vertical and horizontal directions. Proper clamping helps limit material movement and supports consistent cut-face geometry.
The material feeding arrangement uses a servo motor and ball screw. The specified single-feed travel is 6–600 mm. Longer cutting lengths can be achieved through multiple feeding cycles. The loading rack accommodates stock up to approximately 6 m in length, according to the technical configuration.
The cooling system uses an external minimal quantity lubrication arrangement. A controlled supply of lubricant helps reduce friction and manage heat at the cutting area.
The machine incorporates a touchscreen-based control system and programmable operating sequences. The technical design also describes industrial Ethernet connectivity for integration with manufacturing information systems. Such integration depends on the installed controls, communication interfaces, and software configuration.

The technical document contains two cutting-capacity ranges without clearly identifying their corresponding material profiles. The cutting diameter, blade thickness options, and hydraulic pressure should be confirmed against the final equipment specification.
The STK-100NC can prepare metal blanks used in automotive component production. Potential applications include compatible steel bars for shafts, pins, bushings, connectors, and other machined components.
Machinery manufacturers often cut solid metal stock before turning, drilling, milling, or grinding. The automatic cold saw supports repeated cutting of suitable bars and profiles for these processes.
Manufacturers of hydraulic fittings, connectors, and mechanical assemblies may require precisely cut bar stock. Material compatibility and cutting capacity should be confirmed for each application.
The machine can support industrial cutting operations involving compatible steel, copper, and other materials. Its programmable feeding and hydraulic clamping arrangements are relevant to batch production.
The STK-100NC may also be used to prepare blanks for mechanical equipment, industrial hardware, and selected structural components.
The cutting process begins with material detection and positioning. The feeding mechanism transfers the workpiece into the cutting position. The main clamping system then secures the material before the cutting head advances.
After the cutting operation, the blade returns to its original position and the feeding sequence repeats. The production cycle can continue according to the programmed cutting quantity and material availability.
Cutting performance depends on the material properties, blade condition, feed settings, and clamping stability. Finished workpieces should be inspected for:
Specified machine accuracy should be verified using actual production materials.
The technical design describes cutting applications for compatible steel, copper, solid bars, thick-wall tubes, and selected non-metallic materials. Suitability depends on material properties and blade selection.
The specified circular saw blade diameter is 360 mm.
Yes. The documented configuration includes servo-controlled material feeding and a loading rack designed for automatic bar handling.
The machine supports a specified single-feed travel of 6–600 mm. Longer cutting lengths may be achieved through repeated feeding cycles within the equipment's operating limits.
Buyers should provide material grade, outside diameter or profile dimensions, wall thickness where applicable, required cutting length, dimensional tolerance, and expected production volume.
The STK-100NC Automatic Metal Cold Saw Cutting Machine is intended for industrial production requiring controlled material feeding, rigid clamping, and repeatable cutting.
Before selecting the machine, verify the cutting-capacity range, blade configuration, automation requirements, and finished-part quality using representative material samples.
