BS203 center-lathe

● Equipped with a rear turret (BS205/BS206) to enable fully simultaneous machining on both the spindle side and the back‑spindle side. ● The back‑spindle turret features Y-axis rotation (BS206), allowing for fully simultaneous composite machining on both the back side and the spindle side. ● Depending on the workpiece, you can choose between a synchronized guide sleeve or a guide‑sleeve‑free configuration. ● An optional built-in power head enables eccentric hole machining on both the front and back sides. ● Featuring new software that reduces cycle time, enhances machining accuracy, and improves ease of use. ● Increased power head rotational speed, with a maximum speed of up to 8,000 min⁻¹.

Mechanical Body


Product details


  It employs Yixing’s proprietary chuck opening/closing mechanism, replacing the traditional toggle linkage, to enhance spindle roundness. Equipped with precision spindle bearings, it delivers stable cutting at high speeds, extends tool life, and improves surface finish. Designed for ease of operation, it features a standard configuration suitable for miniature parts, a dual‑side chip discharge system, and low capital investment that yields high productivity and strong returns. Overlapping machining reduces cycle time, while the tailstock and its dedicated tool turret enable simultaneous front‑ and back‑side machining. For even higher precision, the advanced high‑accuracy lathe (a model specifically designed without a guide bushing) offers exceptional accuracy; its front bearing utilizes a high‑rigidity spindle bearing, enabling ultra‑high spindle speeds. With the front bearing positioned as close as possible to the cutting point, it achieves exceptionally precise machining. It can clamp bar stock up to φ20.
 
  ● Equipped with a rear turret (BS205/BS206) to enable fully simultaneous machining on both the spindle side and the counter-spindle side.
  ● The back‑spindle turret is equipped with a Y‑axis rotary axis (BS206), enabling fully simultaneous composite machining on both the back side and the spindle side.
  ● A synchronized guide sleeve or a guide‑free configuration can be selected depending on the workpiece.
  ● Optional embedded power head, capable of machining eccentric holes on the front and back sides.
  ● Equipped with new software, it shortens cycle times, enhances machining accuracy, and improves user convenience.
  ● Increase the spindle speed; the maximum speed can reach 8,000 min⁻¹, thereby reducing the machining cycle time for small-diameter holes.
  ● The rapid traverse multiplier function has been added, allowing the machining program to be adjusted under the commanded cutting feed rate.
  ● Comes standard with automatic programming software.
  ● Enhance the rigidity of the bed and tool post to improve cutting performance.
  ● Increased the maximum rotational speed of the four horizontal power heads (standard configuration) to 8,000 min⁻¹.
  ● Enhance chip evacuation capability.

FAQ


Q

How to Select Cutting Tools Appropriately Based on Different Machining Operations

+

A

Machining centers can perform a variety of operations, but different machining processes require different types of cutting tools. The general principles for tool selection should be: ease of installation and adjustment, good rigidity, and high durability and precision. Provided that machining requirements are met, shorter shanks should be chosen to enhance tool‑holding rigidity. When selecting tools, ensure that their dimensions are compatible with the surface geometry of the workpiece being machined.
When machining the peripheral contours of planar parts, it is recommended to use end mills.
When milling flat surfaces, it is recommended to use carbide-insert milling cutters.
When roughing—i.e., machining the blank’s surface—it is recommended to use a corn‑shaped end mill with a carbide insert.
Selecting the appropriate cutting tool is essential to achieving precise, seamless machining and preventing process deviations caused by unsuitable tools, which can lead to tool collisions.

Q

In summer, the weather is so hot—why can’t we open the CNC cabinet to allow it to dissipate heat?

+

A

In summer, to enable the CNC system to operate continuously under heavy load, some people open the CNC cabinet door to improve heat dissipation. Is this approach advisable?
The air in machining workshops typically contains oil mist, dust, and even metal particles. If these contaminants settle on the circuit boards or electronic components within a CNC system, they can reduce the insulation resistance between components and may even cause damage to the components and circuit boards.
Opening the doors of CNC cabinets to dissipate heat will ultimately accelerate the deterioration of the CNC system. Therefore, during extremely hot summer weather, it is advisable to minimize opening the doors of both the CNC cabinet and the high-voltage electrical cabinet. So, how should a CNC system be maintained?
