Purpose of Machine Tool:
SIO-CM300L CNC Cam Milling Machine (Linear Guide Rail) is a modern machine with high efficiency, high precision and high rigidity. It was developed by SIO company and has patents issued by the SIPO. It is mainly used for half finishing or finishing camshafts like S type brake camshafts. Machining cams become very fast and easy. The machine can improve the production efficiency, machining accuracy and saving the cost of human resources. It is the ideal processing machine for automobile, mechanic and other manufacturing industries.

General Description & Main Features:
Machine Bed
The machine bed made by high-grade cast is implemented in stable horizontal framework in order to provide high accuracy and consistent repeatability. The outstanding sturdy machine body is heat treated to relieve stresses. In line with the torsion resisting and sturdy construction, the linear guide rail slider is equipped with ball screws which have high stiffness, accuracy and excellent dynamic performance. Each of these units is driven via high precision servo motor, complete with position feedback system.
The work pieces are processing on the precision index head. Patents technology ensures the work piece has high degree of symmetry and rapid positioning.

Milling Heads
The milling heads mounted on the slides located. Adopt independent unit to ensure good movement precision, stiffness and stability. The drive of the milling heads is conducted via an AC vector motor and via a belt drive to the headstock input pulley.

Hydraulic Unit
The hydraulic unit is a unit connected to the chuck via generously dimensioned hydraulic piping. The hydraulic oil is cooled using an oil heat exchanger.
Dual hydraulic chuck makes automatic clamping. The chuck has internal blowing clearance system. Horizontal positioning with hydraulic lifting. Rapid back after installation.

Electrical control
Relevant parts of the electrical control system of the machine are contained in a switch gear cabinet.

Operating Panel
The machine is equipped with a computer numerical control system Siemens 808D with USB port.
Mobile manual pulse generator is equipped to easy operate.

Accessory
Integrated automatic lubrication system makes the maintenance more reliable.
Configuration cooling pump and enclosed shield.

Equipped automatic chip removal device.

Optional Accessories (Extra Price):

NC system such as FANUC，Siemens,GSK or KND is available for your selection.
