High Speed Machining Center

What is High Speed Machining Center

 

 

The so-called high speed machining center means that the spindle speed and displacement speed are faster than ordinary machining centers. Generally, the spindle speed must reach 10000rpm and the rapid displacement speed is more than 36M to be called a high speed machining center.

 

Benefits of High Speed Machining Center

 

The chips are down (and out of the way)
Aircraft part production may be the only application in which the push broom is a critical tool for precision metalworking.
Getting chips out of the way of the cut is important to both the reliability of the tool and the quality of the part. On a vertical machine such as a gantry mill, that can make sweeping between cycles an essential part of the process.
Horizontal machining eliminates the need to spend time and labor cost on this manual chip removal, because the chips fall away instead. It also reduces the various hazards that result from having chips accumulate while the cycle is underway. Less recutting of chips can result in both a better machined finish and more consistent tool life.

 

Ending blending
Reduced recutting of chips, along with the elimination of dimensional discrepancies between simultaneous tools, results in a more accurate surface with a better finish. Also enhancing the surface quality is high speed machining center itself, which involves lighter cuts and therefore lower cutting forces.
The combination of these factors can let a shop avoid hand blending of machined parts. With high speed horizontal machining, the machined surface becomes the finished surface.

 

Replace three fixtures with one (maybe zero)
Replacing three spindles with one not only eliminates the need for redundant tool sets, but also eliminates the need to own and maintain redundant fixtures.
Meanwhile, high speed machining center itself may reduce the part's fixturing requirements. Cutting forces are lighter, so clamping forces can be lighter as well. It may become practical to machine the part out of a solid block. Using a “picture frame” approach that leaves tabs around the part to secure it to the rest of the block, until the machining is done and these tabs are cut away. With this approach, the only necessary workholding components are the clamps that secure the block to the table.

 

Floor space set free
Moving from a gantry to a horizontal replaces three workpieces with one . . . and the one workpiece that remains doesn't lie on a table but instead is turned on its side. These changes alone allow the machine tool to occupy a smaller footprint.
But the transition frees up floor space in other ways as well. The one-at-a-time approach to machining leaves fewer fixtures to store. It also leaves fewer finished workpieces to store, because each cycle on the horizontal leaves just one piece to manage instead of three.

 

A thrust-to-weight ratio for the process
In a machining process as in an aircraft, weight reduction translates directly to improved performance. For the machining process, that “weight” takes the form of lead time requirements that impede flexibility and inventory requirements that tie up available capital. A high speed horizontal approach to machining large parts can help the process shed these pounds.
First, the cycle time is shorter. That means the shop can deliver a finished part without as much advance notice from the customer.
Meanwhile, the optimum batch size for the machine shrinks from three pieces to one. The shop can run more efficiently in those cases when the ordersize is small.

Key Points of High Speed Machining Center

In high speed machining center (HSM), several critical factors are essential to ensure successful and safe machining processes. Here are three main key points: rigidity, tool balancing, and appropriate clamping methods.

Rigidity:

Machine Tool Rigidity: High speed machining center requires machine tools to have sufficient rigidity to minimize vibration and deformation. High rigidity enables better transmission of cutting forces, maintaining stability of the tool and workpiece.
Workpiece Clamping: When securing the workpiece on the machine, it's crucial that the clamping device provides adequate rigidity to prevent movement or vibration during machining.

Tool Balancing:

Dynamic Balancing of Tools: High-speed rotating tools must be dynamically balanced to avoid severe vibration and deterioration of machining quality. Tool balancing is typically performed using specialized equipment to ensure proper balance.
Balance of Tooling Systems: This includes tool holders, cutting tools, and tool seats, where the balance of all components is critical to prevent excessive vibration and noise during high-speed operation.

Appropriate Clamping Methods:

Uniform Distribution of Clamping Force: When clamping the workpiece, it's essential to ensure that the fixture or clamping system distributes clamping force evenly to prevent workpiece deformation or movement.
Selection of Suitable Clamping Techniques: Depending on the geometric shape and material properties of the workpiece, choose appropriate clamping methods such as mechanical clamping, vacuum suction, or specialized fixtures.

 

High Speed Machining Center Tool Selection Tips
 

Tool geometry
Select the appropriate tool geometry based on the workpiece material, type of machining and machine conditions. For example, different types of cutting tools such as turning tools, milling cutters, and drills have their own characteristics in terms of the shape and Angle of their cutting edges. The parameters of cutting edge sharpness, front Angle and back Angle are considered. For example, in the high-speed processing of cast iron, if the use of carbide tools, the radius of the tool tip is about 0.2mm, and the back Angle is selected at about 12°, it can provide good cutting performance.

 

Material composition
Select tool materials with high hardness and high wear resistance to withstand the high cutting forces and high temperatures generated during high-speed cutting. For example, coating materials such as cemented carbide, cermet, non-metallic ceramics and CBN. Ensure that the tool material has good heat resistance and can withstand the high temperature environment during cutting.

 

Keep tools short
The vibration and centrifugal force generated by a shorter tool at high speed will be relatively small. This is because shorter tools are lighter and therefore easier to maintain stability at high speeds. The reduction of vibration and centrifugal force helps to reduce tool wear, extend tool life, and reduce machining errors.
In addition, shorter tools are also easier to control. This means that during the machining process, the operator can more easily adjust the position and Angle of the tool, resulting in more precise machining.

 

Use special tools
Specialized tools are designed according to the specific processing requirements, and they can better meet the specific processing requirements. For example, the milling cutter is suitable for the machining of flat surfaces and contours, the drill is suitable for drilling operations, and the turning tool is suitable for the machining of outer and inner circles. The use of specialized tools can increase processing efficiency and quality because their design is optimized for specific processing tasks.

 

High speed machine clamping mechanism
High-speed machine tool holding mechanism is a key component to ensure that the tool is stably fixed on the machine tool spindle when rotating at high speed. Select the high-speed clamping mechanism that matches the machine tool to ensure that the tool can be stably fixed on the machine tool spindle when rotating at high speed.

 

Balancing tool
It is a common practice to use a balancing machine to balance the action of the tool. By adjusting the weight distribution of the tool or using a balance block to balance the unbalance of the tool, the vibration and noise generated by the tool during high-speed rotation can be significantly reduced. This helps to improve machining accuracy and surface quality, as well as extend tool life.

 

Clean
Clean the cutting area regularly to remove impurities such as chips and oil to keep the cutting area clean. This helps reduce tool wear and machining errors. Clean and check the tool regularly to ensure that the tool is in good working condition. Check the wear of the tool, coating status, etc., timely replacement of severely worn tools.

 

 
How to Optimize Feed and Speed in High Speed Machining Center?
 

 

 
Machine and spindle

Choose a highly rigid and powerful machine tool, because high speed machining center requires the machine tool and control device to meet the requirements of high feed speed and high cutting speed.
High speed spindle technology is introduced to reduce tool wear and improve machining surface quality by increasing spindle speed.
Optimize spindle design, including selecting the right bearing type and specification, as well as optimizing spindle geometry, material selection and machining process to improve spindle rigidity and stability.

 
Materials and tools

Select the appropriate tool materials according to the type of processing materials, such as diamond tools, cubic boron nitride tools, etc., these tools are suitable for different mold materials and working conditions.
Choose the right blade grade to ensure that the blade can handle the workload, reducing tool changes, scrap and rework.
Consider using a triangular blade because they provide a lower lead Angle and can produce thinner chips, requiring a higher feed rate to maintain the appropriate chip thickness.
Select the appropriate tool geometry (such as tool Angle and blade design) and coating technology (such as TiAlN or TiCN coating) to improve the cutting performance and life of the tool.

 
Job holdings and types of instruments

Use the appropriate fixture and tool holding system to ensure that the tool is stable and accurate during processing.
Consider using high-speed tool systems such as HSK, which have high accuracy and stiffness to reduce tool vibration and displacement during high-speed rotation.
Select the appropriate tool type according to the machining needs, such as end milling cutter, ball cutter or T-cutter, etc., according to the geometry of the workpiece and processing requirements to select the most appropriate tool type and size.

 
Depth of cutting

In high speed machining center, using a smaller cutting depth (usually about 10% of the diameter of the tool) can reduce the cutting force, reduce the cutting temperature, and thus improve the machining quality.
According to the requirements of the specific workpiece and tool, the cutting depth is adjusted to find the balance between the best processing efficiency and quality.

 
Calculate and adjust chip load

In high speed machining center, chip load is one of the key factors affecting machining quality and tool life. Therefore, it is necessary to accurately calculate and adjust the chip load.
When programming, pay attention to the smooth transition of the tool path and avoid sharply changing paths to reduce the fluctuation of the cutting load.
For steep, corner and other positions, the speed should be reduced reasonably to avoid overload and damage to the tool.

 
Programming optimization

Optimize the cutting path through appropriate programming to avoid unrealistic demands on the tool.
In programming, smooth transition and auxiliary trajectory transition are used to deal with the situation that two adjacent tool paths are not smooth.
In the programming, the appropriate adjustment ratio is set, and the cutting parameters are optimized reasonably to keep the reasonable load of the high-speed machine tool.

 
Process optimization

Choose high-speed cutting, large feed, high efficiency processing mode to significantly improve the processing efficiency.
According to different workpiece materials, the appropriate cutting process plan is adopted, including the optimization of cutting speed, feed rate, cutting depth and other parameters.
