Tool layout

Standard machine tool post layout.

‍

Built-in motors are extremely compact and achieve maximum rigidity, a requirement for achieving maximum speeds and exact concentricity.

Built-in motor spindle on front and back spindles

They have high power up to high speed and maintain high precision and low vibration all in one simple mechanical structure. 

Built-in main and back spindle motors increase tooling accuracy.

Built-in motor rotary guide bushing

Servo rotary guide bushing enables high-speed and accurate machining.

Higher precision

• ‍The rigidity of horizontally opposed gang tool posts at main spindle side and the headstock linear guides are increased so tooling accuracy is not influenced by cutting load variation.
• The main/sub headstocks, and X axes (X1, X2) are arranged in a thermal symmetric way, reducing the heat-induced deformation to a minimum. The small thermal displacement of the bed during long periods of operation promotes high accuracy. 
•  High rigid cast machine bed, absorbing the vibration caused by high-speed rotation and rapid traverse.‍

Reduced tooling idle time

• ‍Rapid traverse: Max. 32 m/min (X1: 24 m/min).
• ‍Tool span is only 28 mm, greatly reducing tool change time.

Maximum high-speed control, reducing idle time.

• Two-path control. Programs can be specified at main and back spindle side separately, and they are read and processed at the same time.
• ‍With X2 axis and independent back tool post, simultaneous machining at main and back spindle side can be done.
• ‍M and T codes, axis feed can be specified at the same command block.
• ‍High-speed thread cutting function, reducing thread cutting time.

Convert to chucker mode in minutes

With the increase in material cost in recent years, it’s great that SG-12 has chucker mode to reduce waste. In chucker mode, the machine doesn’t require the space between the guide bushing and the collet so there is less bar remnant. Chucker mode does not require the use of ground bar stocks, so it is suitable for cold-drawn bar machining.  In addition, the powerful chucking force enables heavy cutting, minimizes roughness and improves roundness. The user can choose between guide bushing mode or chucker mode according to the length of the part to be produced and be able to convert to chucker mode in minutes.

Direct C-axis indexing

Unlike conventional machines, direct C-axis indexing enables deceleration to the chosen index position directly, without the need to home return,  reducing spindle indexing time.
