I. Common machining problems of disc parts:
1. Clamping easy to deformation, flatness, parallelism is difficult to guarantee
Thin discs, large diameter discs with poor rigidity, stress deformation after chuck clamping
Loosening after machining, dimensional rebound, flatness, end face runout exceeds the limit
2. High perpendicularity between the end face and the outer circle, difficult to stabilise
End faces, stops, steps and outer rounds to be formed in one operation.
Ordinary machine tools with multiple clamping, perpendicularity and coaxiality are easy to exceed the error.
3. Difficulty in chip removal for machining of face grooves, ring grooves and deep grooves.
Narrow groove, large depth, poor chip removal → wall scraping, broaching, poor surface
Tools are prone to wear and dimensional instability
4. High positional requirements for centre holes, positioning holes and multiple holes
Multi-hole distribution, angled holes, eccentric holes
Difficult to ensure the position and concentricity, high rework rate
5. Cutting of large diameter discs is prone to vibration and vibration patterns.
Large overhang and high cutting force
Poor surface finish, corrugated end faces
6. Fragmentation of processes, inefficiency and high costs
Turning → drilling → milling → tapping on multiple machines.
Many clamps, long cycle times, poor consistency

Second, mill-turn machine solutions:
Turning, milling, drilling, tapping, grooving and boring in one clamping.
Eliminate multiple clamping errors, coaxiality, perpendicularity, positional degree of a standard.
High rigidity bed + high power spindle
Suppresses vibration of large-diameter discs with smooth, vibration-free end surfaces.
Adaptation of soft jaws / special fixtures / hydraulic floating chucks
Reduced deformation of thin discs, stable and controllable flatness and parallelism.
High Pressure Internal Cooling + Optimised Groove Process
Smooth chip removal, smooth groove wall, non-cutting, stable size.
Highly accurate optical encoder closed loop + thermal compensation
Long time batch processing, high dimensional consistency and high yield rate.

I. The most common machining problems of mill-turn parts:
Long shafts are prone to tool vibration, tool letdown, and straightness/roundness is difficult to ensure.
Long slender shaft overhang, poor rigidity, high cutting vibration
Poor dimensional consistency, vibration lines on the surface
Multi-step, multi-groove, multi-thread composite machining, many processes are prone to error.
Turning, milling, drilling, tapping and slotting concentrated in one axis
Multiple clamping results in poor coaxiality and position.
Deep holes, eccentric holes and cross holes are difficult to machine
Poor chip removal, inadequate cooling, easy to break the knife, unstable dimensions
Differential roughness of the inner wall of the hole
High-precision end face, outer circle, taper and arc forming in one go is difficult.
Requires high coaxiality, roundness and finish
Ordinary machine tools require multiple machining, low efficiency
Shaped axes, complex surface machining, high programming and tooling requirements
Difficult to control surface contour
High risk of tool interference and overcutting
Poor stability and low pass rate in batch production
Dimensional drift due to thermal deformation, tool wear
Long time for changeover and commissioning

Second, composite machine tool solutions:
High rigidity bed + high power spindle to suppress vibration and ensure long axis accuracy.
Turning / milling / drilling / tapping / slotting / threading in a single clamping, eliminating double clamping errors.
High-pressure internal cooling + efficient chip removal, stable and reliable for deep holes and difficult-to-machine structures.
Closed-loop control of high-precision guide rail, screw, and grating, micron-level precision and stable output
Intelligent compensation (temperature, tool wear) for higher batch consistency
Professional process solutions + rapid after-sales commissioning, reducing processing difficulties and improving yield rates.

ZhiZhuang deep ploughing into Eastern Europe! We will bring precision CNC machine tools to Moscow International Machine Tool Show 2024!

From 20-24 May 2024, the 24th METALLOOBRABOTKA will be held at Expocentre International Exhibition Centre in Moscow. As the largest and most professional machine tool industry event in Russia, this exhibition attracts more than 1,400 exhibitors from all over the world, with an exhibition area of more than 50,000 square metres, focusing on high-end manufacturing, automation upgrading and core component technology, and has become an annual benchmark event for the industrial field in Eastern Europe and the CIS region.

With the theme of “Precision Intelligent Manufacturing Enabling Industrial Upgrading”, our company participated in this annual event with a full range of products.
At the exhibition site, our booth presented our core advantages with clear technical disassembly and physical demonstration, attracting intensive negotiation among elites from various industries in Russia and Eurasia. In response to the local industrial upgrading of the immediate need for precision components, the team provides one-stop supporting services from product selection, process analysis, configuration, function introduction to batch delivery, accurate docking of customised market demand in the Russian-speaking region.

Relying on the quality and reputation accumulated by years of deep ploughing in the industry, our products have been widely used in the field of precision manufacturing. This exhibition is not only an important layout for the brand to plough into the Eastern European market, but also a concrete practice to help deepen the industrial cooperation between China and Russia with the strength of Chinese precision manufacturing. On the first day of the exhibition, a number of co-operation intentions were reached, covering bulk purchasing, joint development, localised supply and other dimensions, laying a solid foundation for subsequent market expansion.

In the future, our company will continue to focus on precision machining in the field of continuous technological innovation, with higher precision, better quality and faster response, to serve the global high-end manufacturing industry, and continue to develop the Russian-speaking region and the emerging markets in Eastern Europe, for the global manufacturing industry upgrading to provide reliable CNC machine tool processing solutions.
