We present a new lattice formulation of chiral nuclear forces with a simpler decomposition into spin channels. With these interactions the process of fitting to the empirical scattering phase shifts is simplified, and the resulting lattice phase shifts are more accurate than in previous studies. We also present some preliminary results of spectrum of the light and medium-mass nuclei. Our results provide a pathway to \textit{ab initio} lattice calculations of nuclear structure, reactions, and thermodynamics with accurate and systematic control over the chiral nucleon-nucleon force.
