Mechanical
Repair
Services
Mechanical failures demand precise diagnosis and targeted repair. Before any work begins, our technicians conduct a thorough inspection—assessing ball screws, linear guides, spindle assemblies, and structural elements to develop a plan that addresses the problem at its source.
From restoring smooth axis motion to rebuilding spindle performance, our services cover the full range of mechanical systems across both mills and lathes.

Turret Repair
The turret is responsible for precise tool selection and positioning in lathe operations—misindexing or poor locking causes dimensional errors, tool crashes, and costly downtime. Our repair process evaluates indexing mechanisms, alignment, and locking systems to identify the root cause, then restores indexing drives, coupling systems, and locking mechanisms. Each repair is verified through multiple indexing cycles to confirm accurate, repeatable tool positioning under real production conditions. We also provide preventative evaluation and maintenance recommendations to catch early signs of degradation before they lead to major failures.
Our team works with a wide range of CNC lathe turret systems and understands the importance of maintaining proper alignment, timing, and repeatability throughout the machining process. In addition to mechanical repairs, we inspect related components such as sensors, hydraulic systems, servo drives, and communication systems that can impact turret performance. By taking a complete diagnostic approach, we help ensure smooth indexing, reliable locking, and long-term operational stability for your machine.

AATC Repair & Alignment
Automatic Tool Changer (ATC) systems play a critical role in maintaining CNC machine efficiency, accuracy, and production speed. When an ATC becomes misaligned or experiences mechanical or electrical issues, it can lead to failed tool changes, machine alarms, spindle damage, and costly downtime.
We provide complete ATC repair and alignment services, including troubleshooting tool change issues, repairing damaged components, adjusting alignment, and verifying proper operation of the tool change sequence. Our goal is to restore reliable and consistent tool changes so your machine can operate safely and efficiently with minimal interruption.
BLive Tooling Repair
Live tooling enables milling and secondary operations on CNC lathes without additional setups. Loss of rotation, abnormal noise, or decreased cutting performance limits machining capabilities. We assess the unit to identify the exact source, then rebuild internal drive systems, replace worn bearings, address gear wear, and verify alignment within the tooling assembly.
We also evaluate the interface with the turret or spindle to ensure proper fit and power transmission—critical for stable, consistent rotation under load and optimal performance within the entire machine system.
Backlash Checks
Backlash—play between mating components such as ball screws and nuts—causes lag in axis response that directly impacts dimensional accuracy and surface finish. Using precision measurement techniques, we quantify backlash on each axis and identify whether it stems from mechanical wear, improper preload, or component damage.
Corrections may include mechanical adjustments, component replacement, or control parameter compensation—all verified through measurement and test cuts to confirm restored positioning accuracy.
Ballscrew diagnosis and replacement
Ballscrews are one of the most critical mechanical components in any CNC machine, directly responsible for accurate axis movement, positioning, and repeatability. Over time, normal machine operation causes wear on the ballscrew assembly, bearings, and support components, which can lead to backlash, positioning errors, poor surface finishes, vibration, and inconsistent machining performance. At MVC CNC Services, we provide complete ballscrew diagnosis and replacement services to identify the source of axis movement issues and restore machine accuracy and reliability.
Our team works with a wide range of CNC machines and carefully evaluates the condition of the ballscrew system, bearings, couplings, and related axis components to determine the proper repair solution. Whether the machine requires adjustment, repair, or full ballscrew replacement, we follow a structured process to ensure proper installation, alignment, and performance verification. After replacement, we also verify machine movement and axis accuracy to help ensure the machine is operating smoothly and within specification.

AHydraulic & Pneumatic System Repair
Hydraulic and pneumatic systems power tool clamping, axis movement, and automated components. Leaks, pressure drops, or component wear cause performance issues and unreliable motion control. We inspect pumps, valves, regulators, hoses, and actuators, then repair or replace worn components—addressing fluid leaks, pressure inconsistencies, and erratic motion.
All repairs are tested under operating conditions to verify correct pressure levels, responsiveness, and integration with the rest of the machine—keeping your automation cycles stable and consistent.
BAPC Repair
Automatic Pallet Changer (APC) systems are designed to improve production efficiency by reducing setup time and keeping machines running with minimal interruption. When an APC system becomes misaligned or develops mechanical, hydraulic, pneumatic, or electrical issues, it can lead to pallet positioning errors, failed pallet exchanges, machine alarms, and unexpected downtime.
At MVC CNC Services, we provide complete APC repair services, including troubleshooting pallet change failures, repairing damaged components, verifying alignment, and testing the full pallet exchange sequence to ensure safe, smooth, and reliable machine operation.
