Features and Advantages

High-Precision Machining Capacity

This type of CNC surface grinder is equipped with a high-precision bearing spindle, which can control the runout within 1 μm. It offers high rigidity and excellent vibration resistance to maintain a stable machining process, thereby making the grinding wheel maintain stable machining condition. In addition, the high-rigidity hydrostatic rotary table also offers excellent static rigidity that is more than 400 kg/μm. It provides high stability to withstand heavy and duty workpieces, ensuring high surface precision.

High-Precision Machining Capacity
High Efficiency

Compared to the traditional reciprocating surface grinder, the CNC surface grinder with horizontal spindle and rotary table offers higher machining efficiency. Its rotary worktable keeps uninterrupted rotation to help the grindle achieve continuous machining. The drive system also features an accumulator to prevent table damage caused by power failure or pressure loss, thereby enhancing the equipment utilization. The CNC system supports a single setting of machining path and other parameters to ensure automated operation. This can not only reduce manual errors, but also improve overall production capacity.

High Efficiency
Excellent Lubrication System

The HRO series CNC surface grinder is typically equipped with a reliable SKF lubrication system to ensure each key component keeps normal operation. The SKF lubrication system provides continuous and uniform lubrication for the machine, significantly reducing friction and wear. This system features alarm functions to prevent precision decrease caused by dry friction, helping the grinder maintain stable precision with long term use. If your equipment needs to be used frequently, an excellent lubrication system will reduce the maintenance cycle and extend its service life.

Excellent Lubrication System
Highly Automated System

HRO series’ surface grinder is controlled by the CNC system to achieve a high automation level, reducing errors caused by manual operations. It is equipped with specialized software, which offers rich functions and is easy to operate. You can preset machining parameters such as feed methods, grinding cycles, and more, to build the automated production line. In addition, the machine also features a monitoring and automatic compensation system to maintain reliable precision.

Applications

Precision Mold

Mold manufacturing demands high flatness and surface finish, especially the mold inserts, stamping die plates, and cavity locating surfaces. The rotary table of the CNC surface grinder offers high precision and extremely low surface roughness to meet the demand. It is equipped with precise components to achieve optimal surface accuracy of workpieces. You can also input certain programming in the CNC system to ensure high consistency with batch production.

Bearing Industry

The CNC surface grinder with horizontal spindle and rotary table is also widely used to machine ring-shaped components such as bearing rings and valve seat rings. These components typically feature circular structure, which is especially suitable to match with the rotary table. According to continuous grinding with high efficiency, the bearing obtains high flatness. For batch production, this surface grinder also offers excellent consistency to ensure stable quality and dimensional accuracy.

Aerospace

Aerospace components including turbine discs, valve seats, and circular structural components are generally made of materials with high strength. They have strict demands on dimensional precision and reliability. While the surface grinder can ensure high consistency below high machining load. It features high-rigidity structure and automatic compensation functions to machine various types of materials.

Automotive Industry

The automotive industry typically has mass production requirements to meet the market demands. The CNC surface grinder HRO series features high-efficiency spindle and rotary spindle to keep continuous production, meeting the demand of mass production. It is suitable to handle automotive parts, such as brake system components, clutch parts, and other disc-shaped or annular components.

Key Selection Points

A suitable CNC surface grinder with horizontal spindle and rotary table not only helps you complete the production project, but also brings additional benefits. You should analyze comprehensive factors to make the decision. The following are key points that you should consider:
A professional team will help you customize a grinding machine selection solution
  • Table diameter: The worktable determines machining range of the surface grinder, and can be chosen based on workpieces dimensions. You should ensure that the machine you choose features a sufficient table to accommodate the workpiece.
  • Workpiece height: The height between the rotary table with the grinding wheel determines the maximum workpiece height that the machine can handle. It is better to remove certain space for magnetic base plates or specialized fixtures.
  • Spindle power and speed: The spindle is a key component of the CNC surface grinder. Its power and rotation speed is directly connected to grinding capability. If your project involves high-strength materials, strong power is important to ensure a stable machining process. While the spindle speed affects machining efficiency and the surface finish of workpieces.
  • Precision Specifications: When selecting the CNC surface grinder, you should also focus on its key precision specifications such as flatness, surface roughness, and more. These metrics reflect the entire performance of this machine.
  • Control system: HRO series surface grinder is typically controlled by the CNC system to achieve highly automated production. There are various different CNC system brands on the market, you can choose the most suitable one based on actual requirements.
  • Brand and after-sale service: Choosing a reliable brand or supplier is also important to ensure stable quality of the CNC surface grinder. You can demand them to offer certifications of the machine. When your equipment has any failures, ensure the supplier can respond in time, reducing additional loss caused by downtime.

FAQs

Can the rotation speed of the rotary table be adjusted?

Yes. The speed of the rotary table can be flexibly adjusted by the CNC system, you can adjust it based on the actual production requirements. In general, high speed is helpful to improve the surface finish of workpieces. While low speed is more suitable for rough grinding.

Does this surface grinder require professional technicians?

This type of surface grinder mainly relies on the CNC system. It just needs some adjustments on the grinding program, feed rates, compensation parameters, and other simple fixture operations. So even beginners can master the operation after training, and it does not require professional technicians.
